- •
Effect of pilot injection on DMDF combustion characteristic and gaseous emissions were analyzed.
- •
Regulated and unregulated gaseous emissions from the engine with DMDF system were examined.
- •
Compared with single injection, pilot injection strategy could reduce most of gaseous emissions.
- •
Increasing pilot quantity could reduce HC, CO and most of unregulated emissions of DMDF engine.
- •
Advancing pilot injection timing caused an increase in some unregulated emissions on M50 mode.
