Alternatively, a center of a fuel injecting side end port of the fuel injection valve, which injects fuel into intake air that flows in a branch port branched from the intake port, may be placed on the center axis side of the intake valve in a radial direction of the cylinder. Further alternatively, an upstream side fuel injection valve may inject fuel into intake air that flows in the intake port, and a downstream side fuel injection valve may inject fuel into intake air that flows in the branch port branched from the intake port.

  • Patent number: 8141537
    Abstract: A controlling device for an internal combustion engine includes an estimating portion to calculate an estimation value relative to an open degree of a valve based on a predetermined estimation formula. A signal of a sensor is changed, when the valve has a predetermined open degree defined between a full close and a full open. The estimating portion determines that an actual open degree of the valve is smaller than the predetermined open degree, in a case that the signal of the sensor is not changed when the estimation value becomes equal to or larger than the predetermined open degree.

  • Patent number: 8082735
    Abstract: Fuel management system for enhanced operation of a spark ignition gasoline engine. Injectors inject an anti-knock agent such as ethanol directly into a cylinder. It is preferred that the direct injection occur after the inlet valve is closed. It is also preferred that stoichiometric operation with a three way catalyst be used to minimize emissions. In addition, it is also preferred that the anti-knock agents have a heat of vaporization per unit of combustion energy that is at least three times that of gasoline.

  • Patent number: 8051648
    Abstract: An engine includes exhaust manifold integrally formed with a cylinder head. The engine may include an exhaust manifold having at least one single exhaust outlet for exhausting exhaust gas that is exhausted from at least two cylinders that are not adjacent with each other, wherein periods during which exhaust valves are open are not overlapped with each other between the at least two cylinders. The exhaust manifold is integrally formed with the cylinder head such that costs can be reduced. Also, the water jacket is formed between the exhaust passages of the exhaust manifold such that the durability of the turbocharger that is affected by a heat load can be improved. Also, the twin scroll turbocharger is directly connected to the exhaust outlet of the manifold such that the compression ratio of the intake air can be effectively improved.
