Title:
エンジンの制御装置
Document Type and Number:
Japanese Patent JP6554863
Kind Code:
B2
Abstract:
In order to effectively prevent the occurrence of pre-ignition without markedly deteriorating engine output, an engine control device is provided which includes a first fuel injection valve (A) and a second injection valve (B) provided at such a position that the amount of fuel injected by the second fuel injection valve and adhering to the inner peripheral wall of a cylinder is smaller than that of fuel injected by the first fuel injection valve and adhering to the inner peripheral wall of the cylinder. The engine control device further includes a cooling water temperature detecting means (25) for detecting the temperature of cooling water for cooling an engine (1), and an injection ratio determining means (21) for determining the ratio between the amount of fuel injected by the first fuel injection valve and the amount of fuel injected by the second fuel injection valve based on the temperature of cooling water. The injection ratio determining means (21) stores an injection amount adjustment operation range (R) in which the injection ratio determining means is configured to increase the fuel injection ratio of the amount of fuel injected by the second fuel injection valve to the total amount of fuel injected by the first fuel injection valve and the second fuel injection valve, when the temperature of cooling water falls.
