heal.abstract	An experimentally validated simulation code is used to study the development and contribution of various friction components during turbocharged diesel engine transients. This is accomplished with the use of a recently proposed detailed friction model. Mean friction mean effective pressure modelling is found to considerably underestimate actual friction around firing TDC, leading to lower speed droops for abrupt load increases. The piston rings assembly contribution is dominant for the particular engine, due to its high number of piston rings and its low crankshaft speed. The model can be used to investigate such interesting cases as the effect of engine oil temperature on engine transient response, or the variation of oil film thickness during a cycle or a transient event.
