Title:
内燃機関の燃料噴射制御装置
Document Type and Number:
Japanese Patent JP6402749
Kind Code:
B2
Abstract:
A fuel injection control device divides an amount of fuel corresponding to an injection amount required for a single combustion into portions corresponding to multiple fuel injections, causes the direct injector (40) to inject the fuel in the multiple times, and causes the direct injector to execute a partial-lift injection as a final fuel injection. The device includes a total injection amount calculation section (51a), an individual injection amount calculation section (51 b), and an injection amount changing section (51 c). The injection amount changing section (51 c) executes, as a first changing process, a process for increasing the injection amount at the final fuel injection to a value between a partial-lift injection lower limit value (Qpmin) and a partial-lift injection upper limit value (Qpmax) and reducing the injection amount at a fuel injection other than the final fuel injection by the increased amount of the injection amount at the final fuel injection.
