Particulate number and NOx trade-off comparisons between HVO and mineral diesel in HD applications

The results show that the engine injection control and also the fuel quality can influence the formation of NOx and particulate matter significantly. In-particular a potential pilot injection proved highly influential upon whether NOx emissions were reduced or not. When optimising the fuel injection, a reduction in NOx emissions of up to 18% or reductions of PN of up to 42-66% were achieved with simultaneous savings in fuel consumption of 4.3%.
