Effect analysis of the forward flow fuel injection angle on stratified combustion process in a high-pressure direct injection diesel Wankel engine (HPDI-DWE)

The Analysis of the Unconventional Piston Mechanism Conception and Comparison With the Conventional Piston Mechanism

“…For example, the emission of NOx, directly is related to the temperatures which appear in the engine cylinder, son on this can be affected by application of engine with variable compression ratio [11], as well as, by application of HCCI (homogeneous charge compression ignition) engines which give a low emission of nitric oxides, and besides this can achieve a great efficiency [12]. High-pressure direct injection (HPDI) at diesel Wankel engine reduces the particle emission for 39.5% [13]. Besides using the specific engine constructions, and modern engine equipment, the emission of diesel engine can be reduced and by addition biodiesel [14].…”
