First Hydrogen Fuel Cell Car

Hyundai Becomes First Company to Mass Produce Hydrogen Fuel Cell Car.

Hyundai says it will produce 1,000 ix35 Fuel Cell vehicles by 2015. Initial production will be for municipal fleets in Copenhagen, Denmark, and in Skane, Sweden. Early hydrogen vehicle deployments are limited to locations with a refueling infrastucture. With a Hyundai-reported driving range of 370 miles (594 km), there would be no need to refuel until the vehicle returns to the main garage at night.

 

Mass-produced, hydrogen-powered cars were once called the wave of the distant future. Hyundai just advanced the timetable as the first production Hyundai ix35 Fuel Cell crossovers rolled off the production line in Ulsan, Korea, earlier this year. It’s based on the small crossover called the Hyundai Tucson in the US. The ix35/Tucson Fuel Cell converts hydrogen to electricity to power electric motors, rather than burning hydrogen in place of gasoline as BMW has done with its internal combustion hydrogen cars. Either way, the only emission is water vapor.

How Hyundai’s fuel cell works (caution: blonde joke follows): 

Hyundai ix35 Fuel Cell engine compartmentA hydrogen fuel cell works by converting hydrogen to electricity inside the cell, where an anode and cathode are separated by a membrane. At the anode the hydrogen is split into electrons and protons (hydrogen ions). The polymer membrane only allows protons to pass, while the electrons flow through a battery to the electric motor. At the cathode, the hydrogen electrons and protons are reunited and combine with oxygen (outside air) to form water (H2O).

We hear Hyundai may also market a model that converts the components into H2O2, or hydrogen peroxide, for Swedish motorists who are not naturally blonde and wish to fit in. Stay tuned.

The hydrogen is stored in a pair of heavily armored tanks that combine for a capacity of 12.4 pounds (5.6kg) of heavily compressed hydrogen, which is a lot considering hydrogen in its natural, uncompressed state is lighter than air. Locomotion for the ix35 Fuel Cell comes from a 136hp (100kW) electric motor that tops out at 100 mph (160 kph). The energy is buffered by a 24kW lithium-ion polymer battery developed by LG Chemical and Hyundai.

Want one of your own? Today, they’d cost in “the upper $100,000s per car,” Frank Ahrens, a Hyundai spokesman, told US News & World Report. By the time Hyundai shifts from fleet sales to individual buyers, around 2015, the price might fall to $50,000.

The cost of being green

While the only emission from the vehicle is water vapor, there are concerns about how hydrogen gets to be hydrogen in the tank. Right now, a common conversion process takes natural gas, applies energy, and leaves behind a carbon footprint worse than any environmentalist would hope for. You could fare better in the short run just going with a natural gas vehicle such as the Honda Civic Natural Gas. Researchers are working on extracting hydrogen from other sources, whether sea water or the sludge in a waste treatment plant. (See: The fuel cell that turns poop into power.)

This is the third generation hydrogen vehicle from Hyundai/Kia since 1999. Another hydrogen backer is BMW, which showed a series of hydrogen-powered BMW 7 Series vehicles as limited production prototypes. BMW used liquified hydrogen, which requires different equipment at a hydrogen refueling station. While the effort to liquefy is greater, there’s more energy stored in a smaller package (that still takes up more than a third of the big sedan’s trunk). Liquid hydrogen also boils away over a couple weeks if it’s just garaged. But BMW burns the hydrogen in an engine that also burns gasoline, so just like a plug-in hybrid that doesn’t strand you when the battery charge runs down, this one is suitable as a long-distance tourer.

Safer than you think

The Hyundai production start-up preceded by just a couple weeks the (possibly) final word on what brought down the Hindenburg in 1937: a jolt of static electricity when the tethering lines grounded themselves to the earth in Lakehurst, NJ. Despite the jokes, a hydrogen-powered vehicle may be safer than a gas-engine car. The fuel is in incredibly well-armored tanks. If they overheat, the hydrogen is vented directly to the atmosphere and shoots up, while gasoline pools on the ground.

Latest Mechanical Engineering Updates

Two-legged robots learn to walk like a human:

Details -- Teaching two-legged robots a stable, robust "human" way of walking – this is the goal of the international research project "KoroiBot" with scientists from seven institutions from Germany, France, Israel, Italy and the Netherlands. The experts from the areas of robotics, mathematics and cognitive sciences want to study human locomotion as exactly as possible and transfer this onto technical equipment with the assistance of new mathematical processes and algorithms. The European Union is financing the three-year research project that started in October 2013 with approx. EUR 4.16 million. The scientific coordinator is Prof. Dr. Katja Mombaur from Heidelberg University.

Whether as rescuers in disaster areas, household helps or as "colleagues" in modern work environments: there are numerous possible areas of deployment for humanoid robots in the future. "One of the major challenges on the way is to enable robots to move on two legs in different situations, without an accident – in spite of unknown terrain and also with possible disturbances," explains Prof. Mombaur, who heads the working group "Optimisation in Robotics and Biomechanics" at Heidelberg University's Interdisciplinary Center for Scientific Computing (IWR). In the KoroiBot project the researchers will study the way humans walk e.g. on stairs and slopes, on soft and slippery ground or over beams and seesaws, and create mathematical models. Besides developing new optimisation and learning processes for walking on two legs, they aim to implement this in practice with existing robots. In addition, the research results are to flow into planning new design principles for the next generation of robots.

Besides Prof. Mombaur's group, the working group "Simulation and Optimisation" is also involved in the project at the IWR. The Heidelberg scientists will investigate the way movement of humans and robots can be turned into mathematical models. Furthermore, the teams want to create optimised walking movements for different demands and develop new model-based control algorithms. Just under EUR 900,000 of the European Union funding is being channelled to Heidelberg.

Driverless Cars

INVENTIONS OF DRIVER-LESS CARS

Driving is how you get things done yet it also stops you from getting even more things done. If only the act of driving were a thing of the past and you could become a passenger, get out your work, and let the vehicle be a real-life Jeeves. Well, a few companies are getting us closer to that futuristic feeling, though there's still a long way to go.

Here are some news from big players in driverless cars industry.

1-- Toyota's Test:

John Hanson, national manager for environmental, safety, and quality communications for Toyota, says it's gone this far because of the current state of the art in sensors and processing. "There are three basic aspects to how it works," he says. "It's the vehicle's ability to perceive its environment—actually see what's going on. The second part is it can process what it's "looking at." It's one thing to see it, another to understand it. The third part is the response. After it perceives its surroundings, can it respond, and do it quicker and with more precision than the driver?"

But Hanson says the autonomous ability wasn't created to lose the driver but to gain safety. "It's not so much an end game but was specifically a research project to use to further explore an integrated or layered approach to safety. What we showed in Vegas (at the Consumer Electronics Show) was a pre crash collision system. Our current pre-crash automotive technologies have been around for 10 years and have been evolving." Hanson feels the greatest barrier may actually be acceptance, not technological challenge. "Look at how hard it was for people to accept the functionality of a car that parallel parks," he says. "Many people identify themselves with driving. To give that up? Not as easy as you would think."

2-- Google and Audi:

Of course, Google is also in the game. In the first 300,000 miles, the Internet search leader reported that it hadn't had a single accident. With cameras and computers, it's become the eyes of the driver—but it also got the attention of the eyes of Californians, becoming legalized within the Golden State. Google has driverless cars as earmarked to be available within five years.

Audi is a player in the market as well, utilizing radar and LIDAR (light, detection and ranging). It boasts of an app that has the car show up in front of your house…or you can get out at the mall and have it go park itself. It also isn't afraid of heights as it was able to find its way to the top of Pike's Peak. 

Not satisfied, Audi is presently working on a car that actually can make traffic a selling point. While the vehicle is crawling along in gridlock, you can do anything you choose. Of course, it's easy to see the positive—until you ask the driver of that yellow cab you're flagging down. With so many in the driving and delivery industries, there could be countless jobs potentially lost. Even the valet is in trouble. And, for every fare from out of town who enjoyed the conversation of someone who knew the area, the feeling of isolation may be amplified just a little bit more. But change appears to be coming, even if it feels like it's crawling through traffic at the moment.

Emerging Trends in Automotive Engineering

Not too many people know automotive trends the way the staff does at The Ohio State University's Center for Automotive Research (OSU CAR). This interdisciplinary research center at OSU's College of Engineering focuses on advanced electric propulsion and energy storage systems, engines and alternative fuels, intelligent transportation and vehicular communication systems, autonomous vehicles, vehicle chassis systems, and vehicle safety.

"One of the biggest trends right now in automotive engineering is improving engine efficiency and fuel economy," says Giorgio Rizzoni, director of OSU CAR . "This includes downsizing, down-speeding, direct fuel injection, and boosting."

Other engineering trends focus on improving transmissions (adding speeds), accessory load reduction through the intelligent energy management of other vehicle components, vehicle electrification, hybridization, improved battery management systems, new battery chemistries, and power electronics. "Weight reduction in vehicle subsystems is also being tested by using lightweight structures made from alternative materials such as aluminum, magnesium, composites, plastics, and multi-material construction," adds Rizzoni. 

1--Battery Systems:

Battery management systems are being designed to meet performance, life, and warranty goals for both batteries and their monitoring and management systems. "Automakers need to fully understand how varying operational limits affect the life of battery systems through extensive testing and modeling, followed by developing sophisticated algorithms to track and predict various parameters, such as state of charge and state of health through the life of the battery," comments Rizzoni. In order to expand battery operating range and reduce costs, some researchers are designing and testing new battery chemistries and subsystems. Advanced chemistries could allow batteries to operate through greater temperature extremes, last longer, and reduce weight and cost. Other efforts are being made to reduce the cost of the ancillary systems, such as cooling, to further reduce the total cost of the battery system.

2--Downsizing and Turbocharging:

The two main benefits in downsizing an internal combustion engine are thermodynamic and mechanical. "From a thermodynamic point of view, the engine operation will move towards higher loads, at which the engine efficiency is higher," says Rizzoni. "From the mechanical point of view, the positive aspect lies in the reduction of the friction in the piston units, together with the reduction of the number of cylinders."

Downsized engines are lighter than conventional engines, thereby reducing vehicle mass and the improving vehicle fuel consumption. Turbocharging recovers the energy of the exhaust gasses to increase the inducted charge, therefore increasing the power-to displacement ratio. "A downsized and turbocharged engine has the potential to have the same or better performance as a non-downsized, normally aspirated engine, with the advantage of a significant increase of fuel efficiency," says Rizzoni.

3--Advanced Combustion Modes:

Engineers are working to increase the efficiency of internal combustion engines by developing several advanced combustion modes. One of these modes is called (homogeneous charge compression ignition) HCCI. In the HCCI combustion, a highly homogenized mixture of air, fuel, and combustion products from the previous cycle is auto-ignited by compression. "This combustion mode aims at combining the advantages of modern diesel and gasoline combustion processes, namely low emissions and high efficiency," states Rizzoni. Another research trend targets ways to recover the energy that is normally dissipated through the coolant and the exhaust gas systems of automotive powertrains using innovative waste heat recovery devices. These systems can convert thermal energy into mechanical or electrical energy, thus increasing the overall efficiency of the vehicle. Organic Rankine cycle, thermoelectric systems, turbocompounding, and recuperative thermal management systems all have potential for significantly increase engine efficiencies. A smaller but still significant aspect of fuel-efficiency research is called "intelligent energy management." "This ability to more intelligently control the accessory loads in a vehicle—such as the alternator or power steering, etc.—will also contribute to better gas mileage," says Rizzoni.

"With smarter control of these loads and the addition of stop-start technology there can be significant increases in fuel economy, with small or no increase in total vehicle cost."

What is Turbo-Charger ?

A turbocharger, or turbo (colloquialism), from the Latin "turbō, turbin-" ("a spinning thing") is a forced induction device used to allow more power to be produced by an engine of a given size. It consists of a turbine wheel and a turbine housing, converts the engine exhaust gas into mechanical energy to drive the compressor.

The gas, which is restricted by the turbine's flow cross-sectional area, results in a pressure and temperature drop between the inlet and outlet. This pressure drop is converted by the turbine into kinetic energy to drive the turbine wheel.

There are two main turbine types: axial and radial flow. In the axial-flow type, flow through the wheel is only in the axial direction. In radial-flow turbines, gas inflow is centripetal, i.e. in a radial direction from the outside in, and gas outflow in an axial direction.

Up to a wheel diameter of about 160 mm, only radial-flow turbines are used. This corresponds to an engine power of approximately 1000 kW per turbocharger. From 300 mm onwards, only axial-flow turbines are used. Between these two values, both variants are possible.

As the radial-flow turbine is the most popular type for automotive applications, the following description is limited to the design and function of this turbine type.

In the volute of such radial or centripetal turbines, exhaust gas pressure is converted into kinetic energy and the exhaust gas at the wheel circumference is directed at constant velocity to the turbine wheel. Energy transfer from kinetic energy into shaft power takes place in the turbine wheel, which is designed so that nearly all the kinetic energy is converted by the time the gas reaches the wheel outlet.

WHAT ARE THE SCOPES, CAREER PROSPECTS, DEMANDS AND PAY SCALES OF MECHANICAL ENGINEERING IN COMING YEAR ?

Mechanical Engineering finds application in all fields of technology. It is one of the primitive branches of Engineering which have remained always in demand and continue to be in the future. This is why Mechanical trade is called as an Evergreen trade (branch).Mechanical engineering is one of the oldest branches of engineering. It is also referred to as the ‘mother’ branch of engineering. Another appealing feature of mechanical engineering is that the application base of this field of study is extremely broad and diverse. Almost all inventions during the ancient period and a vast majority in the modern era are direct contributions of one or the other application of mechanics. Mechanical engineers have always been needed as an essential staff personnel in various industries of both public and private sector. Their work criteria changes according to the type and domain of the company they are working with.As the Industrial sector has drastically risen in pace, the need for more mechanical engineers has increased exponentially. Every manufacturing and production industry needs mechanical engineers to carry out jobs efficiently and flawlessly for their companies.

The aforementioned are the conventional roles and responsibilities of mechanical engineers. However, times have changed. Nowadays the scope of mechanical engineering is expanding beyond its traditional boundaries. Mechanical engineers are focussing their attention towards new areas of research such as nanotechnology, development of composite materials, biomedical applications, environmental conservation, etc.

Start Early :-

To make mechanical engineering your chosen career path, you must have affinity for the way different machines function. This trait can be observed from early childhood when children try to tinker around with different machinery in their immediate vicinity. Such kids often tend to take apart mechanical toys, clocks, bicycles and then they try to assemble them back again.

These children are so innovative that they may even try to make new things. Here, parents have a special role to play. They must understand that the child possesses an inquisitive mind that is interested in gaining knowledge about machinery and not in breaking or destroying things. Parents must encourage the child’s curiosity to know more about different gadgets and machines in and around the house.

During schooling, the quest to play around with machinery increases all the more. This curiosity often culminates with the child opting for science with the PCM subject combination.

Is it the Right Career for Me?

Like other career paths, the entry into this particular branch of engineering also requires you to possess certain basic traits. First and foremost, you must have a penchant for mechanical components and machinery and how these machines work. Then you must be good at physics, chemistry and mathematics. You must also have skills such as an analytical bent of mind, logical reasoning and problem solving.

Further, you must have immense patience, physical strength, ability to work for long hours and an inventive spirit that are essential ingredients for becoming a successful mechanical engineer.

What would it Cost Me?

A graduate programme from a private engineering institution will cost you anywhere between Rs. 1,0,000 to Rs. 3,00,000 annually. However, in a reputed government run establishment such as the Indian institute of Technology (IIT) or any regional engineering college, you will have to pay an annual fees in the range of anywhere between Rs 30,000 to Rs 40,000.

Funding/Scholarship

Educational institutes offering programmes in mechanical engineering generally extend scholarships to students from socially and economically backward classes. For example, IITs waive off the complete tuition fees for students belonging to the socially backward communities. Scholarships, freeships, stipends and financial assistance are also provided to students on the basis of merit and other qualifying criteria.

Step-by-Step:- 

Passing 10+2 with PCM (Physics, Chemistry and Mathematics) is the first step you take towards becoming a professional mechanical engineer. To be eligible for a graduate programme (BE/BTech) in a college, you should have scored at least 50% marks and 60% for being eligible for IITs (Indian Institute of Technology) in 10+2 with PCM as subjects. After this, you can sit for various entrance examinations such as:

•  The Joint Entrance Examination for IITs (IITJEE) for admission to various IITs

•  All-India Engineering Entrance Exam (AIEEE) for admission to various National Institutes of Technology or regional engineering colleges

Apart from these, there are hundreds of engineering colleges across the length and breadth of the country where you can get into a graduate programme in mechanical engineering. Some of these colleges conduct their own entrance exams whereas some accept AIEEE scores.

You can also opt for a diploma in engineering from a polytechnic. For obtaining a diploma, the basic eligibility is completion of Class 10 with 50% marks. The duration of these diploma courses is three-years for regular and four-years for part-time study.

You can also go for an associate membership qualification from the Institute of Mechanical Engineers, which is considered at par with the diploma earned from a state run polytechnic or a university degree. Another option is to earn a similar qualification offered by the Institution of Engineering (India). Diploma holders can also get direct entry into the second year of a graduate program (lateral entry).

What is Digital Twin Spark Ignition (DTS-i) ?

DTS-i - Digital twin Spark Ignition is a revolution in the modern motorcycling era in the country today and we are the first to offer it to Consumers. This technology offers phenomenal performance augmentation and was introduced for the first time on the highly successful Pulsar twins. It is also being patented by Bajaj Auto Ltd.For faster and better combustion. Currently one spark plug at one end of the combustion chamber is the conventional practice. The flame front created by the spark takes some time to reach the farthest portion of the combustion chamber. This leads to slower burning of the air-fuel mixture and creates limitations in optimizing the combustion chamber characteristics. Two spark plugs at either ends of the combustion chamber help in faster and better combustion.This combustion process of Twin Spark Plugs is being patented by Bajaj Auto Ltd. (Digital Twin Spark Ignition).

What is Anti-lock braking system (ABS)?

Anti-lock braking system (ABS) is an automobile safety system that allows the wheels on a motor vehicle to maintain tractive contact with the road surface according to driver inputs while braking, preventing the wheels from locking up (ceasing rotation) and avoiding uncontrolled skidding. It is an automated system that uses the principles of threshold braking and cadence braking which were practiced by skillful drivers with previous generation braking systems. It does this at a much faster rate and with better control than a driver could manage.

What is Mechanical Engineering?

Mechanical engineering is the study, design, development, construction, and testing of mechanical and thermal sensors and devices, including tools, engines, and machines. Mechanical engineering careers center on creating technologies to meet a wide range of human needs.

Mechanical engineering is a diverse subject that derives its breadth from the need to design and manufacture everything from small individual parts and devices (e.g., microscale sensors and inkjet printer nozzles) to large systems (e.g., spacecraft and machine tools). The role of a mechanical engineer is to take a product from an idea to the marketplace. In order to accomplish this, a broad range of skills are needed. The mechanical engineer needs to acquire particular skills and knowledge. He/she needs to understand the forces and the thermal environment that a product, its parts, or its subsystems will encounter; to design them for functionality, aesthetics, and the ability to withstand the forces and the thermal environment they will be subjected to; and to determine the best way to manufacture them and ensure they will operate without failure. Perhaps the one skill that is the mechanical engineer’s exclusive domain is the ability to analyze and design objects and systems with motion.
