Parametric investigation of natural gas port injection and diesel pilot injection on the combustion and emissions of a turbocharged common rail dual-fuel engine at low load

Yang, Bo; Xi, Chengxun; Wei, Xing; Zeng, Ke; Lai, Ming-Chia - In: Applied Energy 143 (2015) C, pp. 130-137

experiments were conducted to investigate the effects of natural gas injection timing on the combustion and emissions performance … emissions at different natural gas injection timing under pilot injection pressure (46 and 72MPa) and pilot injection timing (−8 …° and −17° ATDC) operation conditions at low load (BMEP=0.24MPa). The results indicated that retarded natural gas injection …
