Title:
内燃機関の噴射制御装置
Document Type and Number:
Japanese Patent JP4135642
Kind Code:
B2
Abstract:
An injection controller for an internal combustion engine that suppresses the accumulation of deposits on a nozzle hole of a direct injection valve. The injection controller (50) includes the direct injection valve (21), which injects fuel into a cylinder, and an intake passage injection valve (22), which injects fuel into an intake passage. An ECU (31), which is connected to the direct injection and intake passage injection valves, executes a first fuel injection mode for injecting fuel with the direct injection valve and a second fuel injection mode for injecting fuel with the intake passage injection valve. The ECU switches fuel injection modes from the second fuel injection mode to the first fuel injection mode for a predetermined period when fuel is to be injected in the second fuel injection mode.
