  • Publication number: 20190226411
    Abstract: A method and system for predicting the occurrence of a knock which will have a predetermined intensity or higher (intense knock) in an engine that burns an air-fuel mixture of gasoline fuel. The pressure in a combustion chamber is detected during an initial stage of combustion. This pressure is compared with a preset reference value to determine whether or not the cylinder inner pressure exceeds the reference value during the combustion. When the cylinder inner pressure exceeds the reference value, it is predicted that the intense knock will occur before an end of the combustion. If the intense knock is predicted, additional fuel or other material can be injected into the combustion chamber to prevent the occurrence of the intense knock.
