Exhaust gas recirculation controller |
摘要 |
An ECU varies a period during which an intake valve and an exhaust valve are both simultaneously open by setting a target overlap angle OVP to be equal to a limit overlap angle OVL until the coolant temperature becomes higher than a reference temperature to reduce the internal EGR amount. This prevents combustion deterioration in a gasoline engine.
