KNOCKING CONTROLLING METHODS OF BI-FUEL ENGINE

摘要

Disclosed is a knocking control method for a bi-fuel engine which uses two types of fuel. According to the present invention, the knocking control method for a bi-fuel engine comprises: a knocking occurrence determination step of determining whether a knocking occurs or a possibility of a knocking occurrence while driving an engine; an auxiliary fuel injection amount calculation step of calculating an injection amount of auxiliary fuel if a knocking occurs or a knocking is expected as a result of performing the knocking occurrence determination step; and a knocking response step of injecting an amount of the auxiliary fuel increased to the amount calculated in the auxiliary fuel injection amount calculation step, and reducing main fuel by the increased amount of the auxiliary fuel to suppress a knocking.
