APPROXIMATION OF CYCLES OF PARAMETERS IN FOUR-STROKE INTERNAL COMBUSTION ENGINE BY MEANS OF HARMONICS METHOD

摘要

The work presents cycle models of cylinder pressure and models of forces in crank-piston system based on a sample of experimental results. The models make it possible to determine the cycles in an arbitrary state of engine operation. Model limitations and the conditions for model applicability are also discussed. An example simulation of the processes is presented for well identified and verified models pertaining to the engine of Polonez 1, 5 GLI automobile.
