CO2 reductions from gasoline engines
27 April, 2022
To reduce CO2 emissions, it is necessary to increase the fuel economy. This implies extracting the kinetic energy from the combustion energy with minimum losses.
Using a leaner air-fuel ratio is recommended, this will result in the reduction of unburnt fuel left behind.
Increasing Compression ratio, increasing compression ratio increases the efficiency of the combustion process. If the mixture is more compressed, the temperatures will be higher, even before the spark and the combustion will be more complete, decreasing CO emissions.
Proper engine tuning is also an important step. The Engine relies on a lot of different systems to operate, including fuel injection, timing, transmission, and other important functions. Engine tuning allows you to fine-tune those processes to get a much cleaner burn. Downsizing of transmission, by reducing the weight of the transmission, reduces the load on the engine thereby reducing unburnt hydrocarbon emissions.
Friction losses can be reduced by replacing the sliding components with bearings where ever possible.By using biofuels (Ethanol) instead of fossil fuels, Ethanol and other biofuels are often touted for their ability to reduce greenhouse gas emissions by replacing fossil fuels. Traditional biofuels like ethanol can reduce greenhouse gas emissions by 19-48 percent compared with gasoline, while advanced or cellulosic biofuels can reduce emissions by more than 100 percent.
Super mileage prototype for the Shell Eco-Marathon

Designing a vehicle body is an art. Art that involves mind of a designer and knowledge of an engineer. When I, a member of bodyworks team of eta, use the surfacing tool 100th time for my 1000th iteration of my design, I get the feeling of utmost contentment. But then I hope one day I will draw a fine beauty that will give me a drag coeff less than 0.05. It will be the day all my team mates will have to stay up all night stacking up mdf sheets, machine them, and then endlessly grind and polish them to bring my thoughts to reality.
From Jugaad to Yugant, our team has always been up to the mark when it came to manufacturing. Every layer of carefully arranged carbon fibre for each car tells the story of our designing brilliance and our industry level manufacturing techniques. It wasn’t easy for us to manufacture a monocoque vehicle in one go, but guess what…we did it!!!
This gives me a sense of assurity when I say my team will join the 500 kmpl group in near future.
Cutting-edge super mileage prototype cars
28 July, 2023
Vehicle dynamics is the science of understanding and optimizing vehicles' performance, handling, and stability. It encompasses a wide range of principles,
including vehicle motion, tire behavior, suspension design, and control systems. The Vehicle Dynamics Department at Team Eta is at the forefront of harnessing
these principles to engineer cutting-edge super mileage prototype cars that deliver unmatched highest mileage, and safety.
The Vehicle Dynamics Department of Team Eta places steering at the forefront of its design philosophy, recognizing it as the conduit that connects the driver's
intent to the car's performance. Meticulously tuning the steering system, they ensure that every turn of the wheel translates into a seamless dance between man
and machine, allowing their drivers to navigate corners with unrivaled finesse and confidence. One of the key components in vehicle dynamics is the tire.
Team Eta's Vehicle Dynamics Department conducts extensive tire testing and analysis to understand the tire's behavior under various conditions. They meticulously
study factors like grip, lateral forces, and tire wear to optimize tire selection for different road conditions. This attention to detail ensures that the
prototype setup is perfectly tailored to extract the maximum potential from the chosen tires.
Forefront of transforming EV technology
