Title: Device for detecting abnormal cylinder of multi-cylinder internal combustion engine
Inventor: UCHIYAMA MASARU
IPC: F02P17/12
Filed: 2000-02-29
Abstract: PROBLEM TO BE SOLVED: To provide a device for detecting abnormal cylinders of a multi- cylinder internal combustion engine without increasing costs, which can detect the abnormal cylinders by the composition of a simple logic circuit. SOLUTION: A minimum instant rotational speed (TNL) and a maximum instant rotational speed (TNH) at the explosion stroke of each of the cylinders are calculated according to NE pulse signals from a crank angle sensor. A single value (DNEk) of a rotational variable time difference, gotten by subtracting TNH from TNL, of each of the cylinders is compared with an average value (NDLT) of the rotational variable time differences of all the cylinders so as to calculate a rotational variable deviation (DDNEk) of each of the cylinders. DDNEk is compared with an abnormality determination value [KDGNOINJ] in order to judge the cylinder as being, a condition of combustion abnormality (misfire) in the case of the relation, DDNEk<[KDGNOINJ]. DDNEk is compared with [KDGEXINJ] to judge an injector mounted on the cylinder as causing excessive injection in the case of the relation, DDNEk>[KDGEXINJ].
