摘要
在一台增压共轨发动机上采用柴油/甲醇组合燃烧(diesel/methanol compound combustion mode,DMCC)方式进行了温度特性研究。对DMCC模式下缸内燃烧温度、缸内燃烧最高温度、进气温度和排气温度与纯柴油模式进行对比分析,结果表明:DMCC模式下的进气温度比原机模式平均下降80%以上,同时也降低了缸内高温持续时间和缸内最高燃烧温度。
Temperature characteristics of a turbocharged common-rail diesel engine in diesel/methanol compound combustion mode （DMCC） were experimentally investigated, and co diesel engine in in-cylinder combustion temperature, peak te Results show that, the intake temperature decreases by more the in-cylinder high temperature period and the peak tempera the theoretical basis for research on simultaneous reduction of mpared with the baseline nd exhaust temperatures. e using DMCC mode, and This conclusion provides NO~ and PM emissions by DMCC mode.
