Title:
COMBUSTION CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/161132
Kind Code:
A1
Abstract:
A combustion control device (28) equipped with: injectors (5) that inject fuel into the combustion chamber of an engine; an electronic control unit (24) configured so as to operate the injectors (5) such that fuel is injected at least twice; and a temperature sensor (27) that detects the temperature of the intake air drawn into the combustion chamber, or the outside air temperature. The electronic control unit (24) obtains the engine load and, on the basis of the obtained engine load, determines the fuel injection amount and the fuel injection timing for the two or more fuel injections. When the intake air temperature or the outside air temperature detected by the temperature sensor (27) is higher than a prescribed temperature the electronic control unit (24) reduces the fuel injection amount for the second determined fuel injection in accordance with the intake air temperature or the outside air temperature.
