Abstract
The influence of different multiple injection strategies on the emissions, combustion noise and BSFC (brake specific fuel consumption) of a small non-road diesel engine prototype equipped with a Common Rail (CR) fuel injection system has been analysed.
The two most critical operating points according to the ISO 8178 - C1 test cycle as far as the exhaust emissions are concerned (Intermediate Speed/Full Load; Rated Speed/Full Load) were considered. Different injection strategies, each with a fixed number of consecutive injections (up to 4), were tested for the selected operating points.
It was found that multiple injection strategies can be very effective also for small displacement non-road diesel engines in reducing particulate matter (PM), NOx and noise levels without increasing fuel consumption.
