CONTROL APPARATUS FOR INTERNAL COMBUSTION ENGINE |
摘要 |
At the time of startup of an engine having an in-cylinder injector and an intake manifold injector, a risk of pre-ignition during the first-time compression stroke is determined based on a rotational angle of a crankshaft at the time of previous engine stop. When there is a high risk of pre-ignition, fuel injection from the in-cylinder injector having been set to make an air-fuel ratio within the combustion chamber become out of a range enabling combustion (to attain an over-rich condition) is carried out in addition to fuel injection from the intake manifold injector for normal engine startup. Pre-ignition is thus prevented, and smooth engine startup is ensured. |
