A team from the Beijing Institute of Technology and Beiqi Foton Motor are proposing a performance optimization strategy for the Atkinson cycle gasoline engine, which is playing a key role in the development of hybrid electric vehicles due to its greater fuel economy than a conventional Otto cycle engine. A paper on their work is published in the journal Fuel . Because the traditional gasoline engine has some shortcomings such as large pumping loss and poor fuel economy at part load, it can no longer meet the demand of HEV for economy and emission. The Atkinson cycle engine has become the main choice for the development of HEV because of its own advantages. Related research points out that 20%–30% of the fuel economy of HEV is attributed to the development and application of Atkinson cycle engine. At present, it is generally believed that Atkinson cycle engine is an ideal […]
