Title:
Injection quantity control device
Document Type and Number:
Japanese Patent JP6107194
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent failure by preventing temperature rise of combustion system components even when an internal combustion engine is operated with high rotation or high load.SOLUTION: An ECU 2 including a fuel injection amount control portion 36 and functioned as a fuel injection amount control device, includes: a running-in operation time determining portion 35 for determining whether a running-in operation time to reduction of sliding resistance of an engine 1, has passed or not. When the running-in operation time is determined by the running-in operation time determining portion 35, a final fuel injection amount is determined by increasing a basic fuel injection amount determined by a basic fuel injection amount determining portion 32 while stopping feedback control, when a rotation frequency of the engine 1 is a prescribed rotation frequency threshold value or more, and a throttle opening of a throttle valve 26 is a prescribed opening threshold value or more, and the fuel injection to the engine 1 is controlled on the basis of the final fuel injection amount.
