Title: Misfire detection device for internal combustion engine
Inventor: SUGIMOTO HITOSHI
IPC: F01N3/023
Filed: 2020-09-25
Abstract: To provide a misfire detection device for an internal combustion engine capable of suppressing degradation of misfire determination accuracy by stop processing of combustion control of part of cylinders.SOLUTION: When not executing regeneration processing to stop combustion control of fuel only in a cylinder #1 (S40:YES), a CPU determines existence/nonexistence of misfire by means of large and small comparison between a value obtained by subtracting a rotation fluctuation amount ΔT30[2] before 360°CA from a rotation fluctuation amount ΔT30[0] as a determination target for the existence/nonexistence of the misfire and a determination value Δth1 (S46). Whereas, in executing the regeneration processing, when setting a cylinder #4 where a compression top dead center appears after 360°CA from the cylinder #1 as a determination target for the existence/nonexistence of the misfire, the CPU determines the existence/nonexistence of the misfire by means of the large and small comparison between the rotation fluctuation amount ΔT30[0] and the determination value Δ (S62).SELECTED DRAWING: Figure 3
