New Hybrid Car Runs On Air!
Hold your breath !! French Car Maker Peugeot is launch hybrid car that runs on air next year.
The Importance of this innovation?
1.To face the worldwide challenges of greenhouse gas and pollution created by vehicles.
2.To show to customers air hybrid car is affordable to great majority in term of price and performance.
What is it exactly?
1. It uses new type of fully hybrid power train that uses petrol and compress air simultaneously.
- Component of car are : a petrol engine,a unit to store energy in the form of compress air,a hydraulic motor-pump assembly and an automatic transmission working with an epicyclic gear train.
- To optimize energy efficiency control system adapts three different mode 1.ZEV(Zero Emission Vehicle) 2.Petrol Internal Combustion and 3.combine of both.  |
Why we take it seriously:
1.Consumption Point of View:
- 69g CO2/km Performance, (If we compare to regular slot Internal combustion engine,manual gear box,benchmark of 104g CO2/km ) For a conventional body style without any specific adaption.
- Saving 45% fuel in city driving, offering a 90% increase in range in comparison with conventional engines.
- Lastly, air compressors and tanks are cheaper than advanced battery technology, meaning the cars will be much cheaper to buy in the first place.
- An automatic transmission that offers a top quality ,smooth and pleasant drive.
- Maintain Vehicle space as it is.(boot,cabin,modular design).
- Reliable and Robust: So less maintenance.
- Small environmental footprint.Easily recyclable materials.
How It Works?
- Air: It allows humans to breathe, airplanes to fly, fills balloons, and is basically a crucial part of our everyday lives. But can it use as a fuel in a car? Most people can only dream about a car that runs on air, but engineers may have found a way to turn it into reality.
- Hybrid Air:
In simplified terms, combustion engines transform fuel into power, which is then used to run the cars up to speed. But all the energy used to get you up to speed is then wasted when you have to brake again, as calipers press on your disk rotors and car get slow down using friction force. The fact that your brakes are really hot to the touch is the most obvious indication that, from a kinetic point of view, you are wasting energy.
Conventional hybrids get solution on this problem using electric motors and generators. Instead of pressing on the brakes, they convert the braking energy into electricity which is then stored into a battery. The distance a car travels while braking looks very small because modern disk brakes are very strong, so it might seem like an insignificant problem, but in theory hybrids recapture the energy used to get you up to speed in the first place.
The Hybrid Air system uses much the same principle to run. It still uses a conventional but very efficient 3-cylinder combustion engine for highway cruising, but also has a motor that runs on air around town. This is stored in a pressurized tank situated in a tunnel under the middle of the car is compressed using a regenerative braking pump.Just like a hybrid can run on petrol or electricity, or a combination of the two, so too will system run on gasoline or air, or both. Air power would be used only during city driving, automatically activated below 43mph (70 km/h) and available for ‘“60 to 80 percent of the time in city driving,” according to the French. The air tank has enough pressure for a daily commute of up to 50 minutes under ideal conditions, a lot better than the 15 or so km range some hybrids of today offer.
we’re concerned about a few technical aspects. For example, compressed air isn't exactly the ideal storage medium. Compressing air usually creates a great deal of heat which will probably have to be vented though an extra radiator.
