Combustion Uniformity as a Measure for Engine Idle NVH 2003-01-1429
Low levels of Engine Idle Shake are required to produce a vehicle that delivers to the customer the overall perception of quality. Some previous metrics used to measure idle shake, e.g. SDIMEP, LNV, etc. have not always been good discriminators of engines that produced low levels of idle shake and those that did not. This paper will propose a new metric, Combustion Uniformity, that does a better job of describing the phenomena that creates idle shake. This new metric will then be used to describe how different distributions of cylinder-to-cylinder variation create different levels of Combustion Uniformity and how those levels of Combustion Uniformity compare to previous metrics.
