Title:
燃料噴射制御装置及び内燃機関
Document Type and Number:
Japanese Patent JP5035366
Kind Code:
B2
Abstract:
An ECU of a fuel injection controller acquires information on a load of an internal combustion engine including a fuel injection valve. Based on the load information, a switch is made between low-load-condition control, in which a main injection is performed at a timing that avoids a spray injected by a pilot injection that drifts due to a swirl effect, and high-load condition control, in which the main injection is performed at a timing that interferes with (at least partially overlaps) a spray injected by the pilot injection that drifts due to a swirl effect. In the low-load-condition control, the spray injected by a pilot injection is diffused before the occurrence of ignition to reduce smoke. In the high-load condition control, the spray injected by the main injection is caused to interfere with the spray injected by the pilot injection that contains OH radicals, to reduce smoke.
