INTERNAL COMBUSTION ENGINE CONTROL DEVICE

Title:

INTERNAL COMBUSTION ENGINE CONTROL DEVICE

Document Type and Number:

WIPO Patent Application WO/2013/111299

Kind Code:

A1

Abstract:

This internal combustion engine control device is a control device for an internal combustion engine equipped with fuel injection valves (12) having a nozzle body (12a), which is equipped with a fuel accumulation part (12d) and multiple spray holes (12e) downstream from a seat part (12a1) that makes contact with the seat-contacting part (12b1) of a needle valve (12b). In addition to a main injection for generating torque with the internal combustion engine (10), the control device executes one or more minute injections during one cycle. Furthermore, when variation in a learning value for the fuel injection amount based on learning control can be detected, and a post-injection has not been performed in the previous cycle of the internal combustion engine (10) and a first minute injection is performed in the current cycle, the control device increases the amount of fuel injected with this first minute injection during low-load operation, and decreases the amount of fuel injected with this first minute injection during high-load operation.
