  • Patent number: 10393041
    Abstract: Methods and systems are provided for operating a split exhaust engine system that provides blowthrough air and exhaust gas recirculation to an intake passage via a second exhaust manifold and exhaust gas to an exhaust passage via a first exhaust manifold. In one example, in response to an intake throttle being at least partially closed, intake air may be routed from the intake passage to the second exhaust manifold via an exhaust gas recirculation (EGR) passage where the intake air may be heated via an EGR cooler. The heated intake air may then be routed to an intake manifold, downstream of the intake throttle, via a flow passage coupled between the second exhaust manifold and the intake manifold.

  • Patent number: 10316810
    Abstract: A vehicle control system is provided which is used in a vehicle equipped with an engine as a drive power source and works to establish engagement of a pinion of a starter motor with a ring gear mounted on a rotational axis of the engine and then actuate the starter motor to start the engine. The vehicle control system executes a preset mode to move the pinion to achieve the engagement with the ring gear when the rotation speed of the engine has dropped below a given threshold value. The threshold value is determined as a function of speed of the vehicle, thereby alleviating a driver's perception about unwanted mechanical noise arising from impact the pinion on the ring gear upon the engagement therebetween.

  • Patent number: 10221804
    Abstract: A fuel injection control device for an internal combustion engine, includes a fuel pressure sensor and circuitry. The fuel pressure sensor detects an actual fuel pressure of the fuel supplied to a cylinder fuel injection valve. The circuitry calculates a demanded amount of the fuel supplied to the internal combustion engine. The circuitry calculates a cylinder injection amount of fuel injected from the cylinder fuel injection valve. The circuitry corrects the cylinder injection amount to decrease in accordance with a degree of drop in the actual fuel pressure comparing to a target fuel pressure of the fuel supplied to the cylinder fuel injection valve such that fuel injection from the cylinder fuel injection valve ends by a target injection end timing. The circuitry calculates a port injection amount of the fuel injected from a port fuel injection valve based on the demanded fuel amount and the corrected cylinder injection amount.
