Abstract
An internal combustion engine comprises a fuel injector, a spark plug, an evaporated fuel purge device purging evaporated fuel in the fuel tank into an intake passage, and a control device. The control device can perform spark assist control for sequentially injecting premix-forming fuel and injecting ignition assist fuel from the fuel injector, while controlling the fuel injector and spark plug so as to make an air-fuel mixture formed by the injection of ignition assist fuel burn by the spark plug by flame propagation and to make the remaining fuel burn using the heat released by the flame propagation combustion by premixed compression self-ignition, and the control device makes the injection amount of premix-forming fuel decrease without changing the injection amount of ignition assist fuel when purging evaporated fuel into the intake passage by the evaporated fuel purge device compared to when not purging it.
