摘要：
For effectively suppressing the pre-ignition and harsh combustion in hydrogen engine, the application of low temperature combustion technique to hydrogen engine is attempted. The prediction model for low-temperature combustion is established and the characteristics and implementing mechanism of low-temperature combustion in hydrogen engine are analyzed. The results indicate that low-temperature combustion, which is achieved by increasing high specific-heat components and reducing oxygen concentration of in-cylinder charge, can effectively control the combustion reaction velocity, suppress the pre-ignition and harsh combustion and reduce NO pollutant in hydrogen engine. With the rise of EGR rate, combustion reaction slows down, combustion duration extends and heat release shows a feature of “slow and lengthy”. © 2017, Society of Automotive Engineers of China.
