- Summary:
- Highlights:
NOx (nitrogen oxides) emission of PCCI (premixed charge compression ignition) engine reduced with an increase in DME (dimethyl ether) pre-mixing ratio and EGR (exhaust gas recirculation) rate.
•Smoke emission decreased with an increase in DME pre-mixing ratio and a decrease of EGR rate.
•ηet for PCCI engine improved with an increase in DME pre-mixing ratio and a decrease of EGR rate.
•Effects of EGR on PCCI combustion gradually weakened with a rise of DME pre-mixing ratio.
