Multipulse Ballistic Injection: A Novel Method for Improving Low Temperature Combustion with Early Injection Timings

Nowadays, increasingly stricter regulations on emission reduction are inducing rapid developments in combustion science. Low-temperature (LTC) is an advanced technology that increases engine’s thermal efficiency and even provides low emissions of nitrogen oxides (NOx) particulate matter (PM). The often uses early direct injections to achieve sufficient mixture homogeneity. This leads increasing wall wetting lower efficiency. paper introduces the Multipulse ballistic injection (MBI) method improve with timings. research was carried out a four-cylinder medium-duty diesel engine high-pressure exhaust gas recirculation (HP-EGR). investigation divided into two experiments. In first experiment, MBI examined without EGR, second, EGR applied study its effects. It found strategy decreased increased homogeneity indicated mean effective pressure (IMEP) at angles.
