Title: Misfire judging method for each engine cylinder
Inventor: IMAI RYUICHIRO
IPC: F02D45/00
Filed: 1990-11-01
Abstract: PURPOSE:To precisely detect a misfire state by comparing a difference in momentum during a non-working period of combustion between a cylinder before two combustion strokes and a cylinder before one combustion stroke with a misfire judging level set on the basis of an engine combustion state parameter of a cylinder before one combustion stroke so as to determine the misfire state for each cylinder. CONSTITUTION:A combustion state of a cylinder before one combustion stroke is determined based on an average value of momentum during a non-working period of combustion of the cylinder before a combustion stroke before and after the same. A comparison value is compared with a misfire judging level set corresponding to an engine state of the cylinder before one combustion stroke, thereby determining a misfire state of the cylinder before one combustion stroke. Therefore, the misfire state can be precisely detected without any effect of variation of combustion between the cylinders and variation of manufacture of each engine.
