Experimental investigation into particulate size and number distribution from a spark ignition engine: in-cylinder combustion and transient events
Recently, nano-scale particulate matter has been added to the list of regulated emission species for gasoline engines. However, the chemical mechanisms responsible for the formation of particles during gasoline combustion are yet to be fully identified. We examined and identified the correlation between combustion cyclic variability and statistical variation in engine-out nano-scale particulate matter. This fundamental work gave us the insight to control particulate matter from gasoline engines. The outcomes led to industrial links and sponsorship for establishing test methods, measurement schemes for gasoline direct injection engines towards EURO VI engine calibration for two major European vehicle manufacturers.
