Summary:

In order to understand the effects of pulse injection mode on power output and emissions in an HCCI diesel engine, the pulse injection mode modulation was investigated. A computer simulation code of common rail injector FIRCRI was developed based on previous work by the authors, including the simulation of dynamic response and injected fuel amount. Then the injector parameters were partly revised to meet the requirement of pulse injections. By variation of control signals, a series of injection modes were realized based on the prejudgment of combustion requirement. The designed injection modes included so called even mode, staggered mode, hump mode and progressive increase mode with four, five and six pulses. Engine test was conducted with the designed injection modes. The experimental results showed that the HCCI diesel combustion was extremely sensitive to injection mode. There were many ways to reach near zero NOX and smoke emissions, but the injection mode must be carefully designed for higher power output
