Abstract
A HCCI engine () is able to supply two types of fuels with different octane numbers to each cylinder () through fuel supply devices (and). A fuel supply control means () of a controller () increases a proportion of a supplied quantity of a low-octane fuel in the entire supplied quantity of the respective two types of fuels to a combustion chamber greater than a normal proportion defined by a normal control operation value group determined by a predefined control rule according to a FC correction processor () in a predefined duration immediately after a return of a working mode from a fuel-cut mode to a normal mode. Thereby, it is able to efficiently perform combustion of the fuel-air mixture in the combustion chamber even after the return of the working mode from the fuel-cut mode to the normal mode when a temperature in the combustion chamber is low.
