| titleOfInvention | Engine controlling gas flow in cylinder |
| abstract | (57) [Summary] [PROBLEMS] To make it possible to quickly develop gas flow in a cylinder when shifting from rich shift control to lean combustion operation, and to quickly shift to lean combustion operation without impairing engine stability. . An engine (1) includes means for controlling an air-fuel ratio, and a gas flow control valve (12) provided upstream of an intake valve and controlling gas flow in a cylinder according to the air-fuel ratio. The opening degree of the gas flow control valve 12 is adjusted to enhance the gas flow in the cylinder. The engine control unit (ECU) 9 determines whether lean combustion is performed, When it is determined that the lean combustion is performed again after the air-fuel ratio is temporarily made rich, the gas flow control valve 12 during the rich shift is controlled to the opening required for the lean combustion operation after the rich shift. As a result, when shifting from the rich shift control to the lean combustion operation, the gas flow control valve 12 has already reached the opening required during the lean combustion operation, and the gas flow has developed in the cylinder. Can be moved quickly. |
