Title:
ENGINE KNOCKING DETERMINATION DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/162805
Kind Code:
A1
Abstract:
Provided are an engine knocking determination device and method for a divided chamber type engine for injecting flames from an auxiliary chamber into a main chamber for combustion therein, the engine knocking determination device comprising a pressure amplitude acquisition unit that acquires a pressure amplitude of the main chamber, a region division unit that divides the pressure amplitude acquired by the pressure amplitude acquisition unit into a first region up to a cylinder pressure maximum value and a second region from the cylinder pressure maximum value onwards, and a determination unit that compares a first maximum amplitude of the pressure amplitude in the first region with a second maximum amplitude of the pressure amplitude in the second region to determine occurrence of knocking.
