Abstract:

This project has the aim of refining an existing zero-dimensional diagnostic tool developed in Matlab environment in order to analyse the combustion process of a compression ignition engine. The engine under exam is the F1A engine (FPT Industrial), a turbocharged diesel engine with a displacement of 2.3 litres. In addition to the common diesel fuel, a renewable fuel was also used (HVO) in order to evaluate what benefits could be achieved using this type of new fuel. Two models were used inside the tool: a complete one zone model and a three zone model, that is also used in order to evaluate the evolution of particulate matter (PM) and nitrogen oxides (NOx) emissions as function of the crank angle. The investigated injection strategy has two pilot injections and a main one (ppM injection strategy) at three key points (1250x2, 2000x8.96 and 2250x15), with different EGR rates.
