  • Patent number: 10208698
    Abstract: A direct fuel injection internal combustion engine having an injector for directly injecting fuel into a combustion chamber thereof is provided. The engine is configured so that a tumble flow is generated in the combustion chamber. A fuel injection by the injector can be performed in a first injection mode and a second injection mode, the first injection mode being a mode in which the fuel injection is completed after the tumble flow is generated, and the second injection mode being a mode in which the fuel injection is completed before the tumble flow is generated. The fuel injection of the first injection mode is performed before completion of the warming-up of the engine, and the fuel injection of the second injection mode is performed after completion of the warming-up of the engine.

  • Patent number: 10180113
    Abstract: A control system for an internal combustion engine, which is capable of controlling fuel injection valves while causing valve-closing delay time periods, which occur with the valves actually mounted on the engine, to be reflected thereon, thereby making it possible to improve exhaust emission characteristics and fuel economy performance. The ECU of the control system performs initial value-specific control in fuel injection control and ignition timing control, such that initial value acquisition conditions are satisfied, so as to calculate the initial values of the valve-closing delay time periods when the initial value acquisition conditions are satisfied. When normal-time control is performed, the valve-opening time periods of the valves are calculated using the initial values of the valve-opening time periods, and the valves are controlled to be open over the valve-opening time periods.

  • Publication number: 20170276088
    Abstract: A fuel injection device for an internal combustion engine including a cylinder, includes a fuel injection valve and a processor. The fuel injection valve injects fuel directly into the cylinder. The fuel injection valve has an injection hole which has a diameter and a length in an axial direction of the injection hole. A ratio of the length to the diameter being 1.0 or smaller. The processor is configured to determine, in a cold operation of the internal combustion engine, a fuel injection time during which the fuel injection valve continues to inject fuel such that an amount of soot in exhaust gas is less than an amount of soot in exhaust gas if the fuel injection valve has the ratio larger than 1.0.

  • Patent number: 8726890
    Abstract: An intake air heating apparatus may include an air pump, an intake chamber, an air heater, and a delivery pipe associated with an intake manifold. When intake air is heated, a throttle valve may be closed, the air pump may be started, and electrical power may be supplied to the air heater. The air flowing from the intake chamber may be heated by the air heater. Thereafter, the air may flow from the delivery pipe into branch pipes and circulate to the intake chamber. At that time, since the throttle valve may be closed, and an intake valve or an exhaust valve of an engine may be closed, the heated air may not flow out and the air temperature in the intake manifold and the intake air heating apparatus may increase.
