INVARIANCE OF POSITION OF POINT OF THE MAXIMUM COMPRESSION SPEED POSITION FROM PRESSURE

Abstract

It’s given the analysis of indicator diagram of diesel engine in the point of fastest rate of change of pressure. This part of diagram begins after closing of inlet valves. It’s typically for the most of diesel engines that rate of change of pressure has the maximum before the beginning of combustion. It’s given in article the derivation of very interesting and important property of the point of fastest rate of change of pressure: position of this point depends only from dimensions of crank mechanism and compression ratio. It means that this point could be calculated before taking the indicator diagram of diesel engine.
