Multiple-benefit technology development for gasoline-diesel-hybrid powertrains

Modern spark ignition and compression ignition engine solutions have been characterized in the paper The requirements that the modern engines are currently facing are a compromise between the expectations of the clients and the technological capability of obtaining a significant reduction in the fuel consumption and emissions. The solutions applied in the CI and SI engines contribute to the above expectations and constitute a basis for further development i.e. hybrid propulsion combining SI and CI engines with electric machines providing much higher fuel economy and comfort.
