CONTROL APPARATUS AND CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE |
摘要 |
A control apparatus for an internal combustion engine is provided. The internal combustion engine includes an exhaust catalyst and a fuel injection valve. The control apparatus includes: an electronic control unit. The electronic control unit is configured to: (a) acquire a cetane number of a fuel for the internal combustion engine; (b) acquire a target light-off temperature on the basis of the cetane number, the target light-off temperature being a light-off temperature of the exhaust catalyst; (c) acquire an exhaust gas temperature of the internal combustion engine; and (d) when the exhaust catalyst is heated, control additional injection on the basis of a difference between the exhaust gas temperature and the target light-off temperature, the additional injection being carried out after main injection of the fuel injection valve. |
