The Diesel Hybrid Combustion Engine Essay -- Auto Cars Automobiles Mec

The Diesel Hybrid Combustion Engine Two main types of engines powering everyday machinery are diesel and gasoline internal combustion engines. Both vary on efficiency levels, but are still effective. Diesel engines have high efficiency levels, such as producing great amount of torque at very low rpms. They are also known for their fuel-efficient behavior and capability to produce low emissions. Their capability to produce power at an efficient rate with little wear on the engine, this makes these engines ideal for hybrid integration. Hybrid integration takes a typical engine and combines it with an electric generator and motor, with the application of other electrical systems applied. Allowing the machinery to generate energy, with lower fuel consumption and cleaner emissions. Toyota is one of the leaders in the automobile hybrid design. The design goes as follows, â€Å"a VVT-I gas engine with an advanced electric motor to not only power the Prius, but also recharge the vehicle's batteries thanks to an ingenious generator and regenerative braking system†¦Ã¢â‚¬  (Toyota). This regenerative braking system allows absorption of the heat energy used to brake and uses that energy to recharge the cars batteries. This system makes the car self-reliant. Even though this engine uses gasoline, the development of diesel hybrids will be the next step in innovation. Comparison: One of the main areas is the on-board fuel combustion of these engines. In tests performed by MIT, the relative consumption of on-board fuel energy for a typical gasoline internal combustion engine measured about 88%, while the Diesel-Hybrid was at 52% (Weiss 27). These tests demonstrate how much more ene... .... Design News (19 August 2002): 1-5. Peckham, Jack. â€Å"Diesel Hybrids Come Out Best In Energy, Greenhouse Gases†.
