Version of Record

In recent years, internal combustion engines have been widely used in automobiles and power generators. However, to realize a sustainable society, it is necessary to improve thermal efficiency by improving existing internal combustion engines. As one of the methods to improve thermal efficiency, we are studying a multi-stage impinging injection method. In this study, we investigated the effects of premixing and fuel atomization by changing the fuel injection ratio on the combustion characteristics from the viewpoints of heat release ratio, Ignition delay time(ID), Total heat release(THR), total burning time(TBT), and Maximum burning pressure(MBP). The main conclusions are as follows: (1) It is possible to control combustion by the ratio of premixed combustion using multi-stage impinging injection. (2) When the multi-stage impinging injection is used, the THR is increased by up to 8% even at the same overall equivalence ratio by controlling the injection amount and injection timing of different fuels. (3) When the multi-stage impinging injection is used, the MBP is increased by up to 9% and the TBT is reduced by up to 10% by controlling the injection amount and injection timing of different fuels.
