Title:
燃料噴射制御装置
Document Type and Number:
Japanese Patent JP5182250
Kind Code:
B2
Abstract:
In a compression stroke, fuel injection valve 2 injects a single portion of the fuel immediately after -28° ATDC. Immediately after this injection, a second portion of the fuel is injected as close as possible to the first injection without overlapping. The amount of the fuel injected in the second injection takes a value obtained by subtracting the amount of the fuel injected in the first injection from the amount of the fuel required to obtain a required torque, and this amount is larger than the amount of the fuel injected in the first injection. Next, fuel injection valve 2 injects a single portion of the fuel immediately after -18° ATDC. The amount of the fuel injected at this time is approximately double the amount of the fuel injected in the first injection at -28° ATDC timing and smaller than the amount of the fuel injected in the second injection.
