摘要：

Optimization strategies of reducing HC and CO emissions were studied experimentally on a turbocharged and inter-cooled common rail diesel engine of CA6DL during the low temperature stage of two-stage combustion process. The results show that during the typical low-temperature combustion(LTC) stage with single injection case, increasing fuel injection quantity and delaying the injection timing can increase the combustion temperature and thus reduce HC and CO emissions. Furthermore, better combustion efficiency and HC/CO emissions can be obtained with NOx emissions almost unchanged by increasing injection times due to the decrease of the fuel amount per injection and improving fuel/air mixing condition. The best optimization strategy among different injection strategies is the uniform distribution of fuel injection strategy as it can avoid the sharp increase of NOx or HC and CO caused by extremely high or low combustion temperature in cylinder. © 2017, Editorial Office of the Transaction of CSICE.
