Control device of in-cylinder direct-injection internal combustion engine

摘要

A requested injection amount of fuel necessary during ignition cut-off at the time of start at an extremely low temperature is calculated (step ST 2 ), injection start timing and injection end timing between which wetting of a spark plug by fuel is less likely are set (step ST 3 ), and the number of times of ignition cut-off is calculated based on the injection start timing and the injection end timing and the requested injection amount (step ST 4 ). The injection start timing and the injection end timing are thus restricted to timings between which plug wetting is less likely, and the number of times of ignition cut-off is calculated based on the injection start timing and the injection end timing and the requested injection amount, so that wetting of the spark plug by fuel at the extremely low temperature can be avoided even in an in-cylinder direct-injection engine.
