The objective of present work is to obtain a strategy for adapting injection conditions to varied engine speeds in two-stage direct-injection PCCI operation in a diesel engine. To this end, an experimental study was conducted using a single-cylinder test engine varying first- and second-injection timings. The results indicate that problems of high maximum pressure rise rate at a low engine speed and low thermal efficiency at a high engine speed can be solved by adjusting injection timing. However, under a high engine speed condition, there remains a problem of increased CO emission.
