Title: Controller of internal combustion engine
Inventor: SHIBATA RYOHEI
IPC: F02D45/00
Filed: 2020-01-20
Abstract: To provide a controller of an internal combustion engine capable of further improving detection accuracy for knocking occurring during a cylinder expansion stroke.SOLUTION: A controller of an internal combustion engine is configured to determine if knocking has occurred in a cylinder with reference to the output signal of a knock sensor that detects the vibration generated in a cylinder block including the cylinder of the internal combustion engine. While the controller determines the presence or absence of knocking based on the output signal of the knock sensor in a determination section during an expansion stroke of the cylinder, the output signal of the knock sensor outside the determination section will not be used to determine the presence or absence of knocking, and start timings t1, T1 of the determination section are variably adjusted according to the ignition timing at that time or the operating region of the internal combustion engine.SELECTED DRAWING: Figure 2
