Title:
FUEL INJECTION CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2016186256
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce an error of fuel injection amount and suppress deterioration of exhaust properties by reducing an error of an air-fuel ratio at various types of start.SOLUTION: A first fuel injection valve 6 in which the volume of a fuel flow passage leading from a valve element 43 to an injection plate 41 is set relatively small so as to generate an error on an increase side of the fuel injection amount in accordance with an increase in a fuel temperature and a second fuel injection valve 7 in which the volume of the fuel flow passage leading from the valve element 43 to the injection plate 41 is set relatively large so as to generate an error on a decrease side of the fuel injection amount in accordance with an increase in the fuel temperature are disposed at suction ports 4, 5. Due to this configuration, the error on the fuel injection amount increase side of the first fuel injection valve 6 and the error on the fuel injection amount decrease side of the second fuel injection valve 7 are offset in accordance with the increase in the fuel temperature so as to enable reduction in an error of the total fuel injection amount per cylinder and suppression of deterioration of the exhaust properties.SELECTED DRAWING: Figure 4
