Abstract The presented test results contain an analysis of the variable control fuel flow from high-pressure gasoline injectors. To such a system, cRIO 9063 system and NI-driven module were used. This allows controlling piezoelectric injector with time-varying needle height, which affects during single-time opening needle. tests carried out in constant volume chamber dose ( P inj = 15 MPa q o 1...

Due to the shortage of liquid hydrocarbon fuels for compression ignition engines, researchers have constantly been looking for alternative fuels. Recently, dim ethyl ether (DME) with its interesting properties, such as high cetane number and low exhaust emission has drawn a lot of interst as a suitable fuel for diesel engines. The main objective of this study was to assess the potentials and fe...

A multi-pulse injection strategy for premixed charge compression ignition (PCCI) combustion was investigated in a four-valve, direct-injection diesel engine by a computational fluid dynamics (CFD) simulation using KIVA-3V code coupled with detailed chemistry. The effects of fuel splitting proportion, injection timing, spray angles, and injection velocity were examined. The mixing process and fo...
