  • Patent number: 9695755
    Abstract: Methods and systems are provided for addressing pre-ignition occurring while operating with blow-though air delivery. A variable cam timing device used to provide positive intake to exhaust valve overlap is adjusted in response to an indication of pre-ignition to transiently reduce valve overlap. Pre-ignition mitigating load limiting and enrichment applied during a blow-through mode is adjusted differently from those applied when blow-through air is not being delivered.

  • Patent number: 9670880
    Abstract: A gaseous fuel feed apparatus includes a first injector and a second injector which are provided in each cylinder of a gas engine. The first injector injects a gaseous fuel into an intake passage. The second injector injects the gaseous fuel in an injecting direction intersecting with an injecting direction of the gaseous fuel injected by the first injector, such that the gaseous fuel injected by the second injector collides with the gaseous fuel injected by the first injector. Thus, the gaseous fuel injected by the first injector can be forcibly pressed toward a flow of an air by utilizing an injection energy of the gaseous fuel injected by the second injector. Further, the first injector and the second injector may be placed at the same position of the intake passage, and can be placed at a position of the intake passage that is adjacent to a combustion chamber.

    Abstract: First intake valve and second intake valve for an engine cylinder bore within which a piston reciprocates are arranged side-by-side in a cylinder head for motion in unison along respective intake valve axes. First intake valve axis is nonparallel to the cylinder bore axis. A first intake valve seat for the first intake valve is disposed in a plane which is non-parallel to a plane which is perpendicular to the cylinder bore axis. First intake valve seat has a first semi-circumference toward a second semi-circumference of a second valve seat for second intake valve. At least a portion of first semi-circumference is closer, as measured along a direction parallel to the cylinder bore axis, to a plane passing through the piston perpendicular to the cylinder bore axis than is the second semi-circumference as measured along a direction parallel to the cylinder bore axis.

  • Patent number: 9638148
    Abstract: An air intake chamber for a motorcycle is disposed downstream of a supercharger, for pressurizing and supplying an intake air to an engine, and upstream of a throttle body, for controlling the amount of the intake air to be supplied to an air intake port of the engine. The air intake chamber serves to accumulate the high pressure intake air discharged from the supercharger. The air intake chamber is provided with an injector, which has a fuel injecting port positioned at a location displaced from an axis of an outlet of the air intake chamber.

  • Patent number: 9222449
    Abstract: An internal combustion engine can form, in a combustion chamber, a fuel-air mixture region located on the first intake port side and containing mainly a fuel-air mixture, and a burned gas region located on the second intake port side and containing burned gas. When the fuel-air mixture region and a burned gas region are formed, the internal combustion engine determines injection rates of a first fuel injection valve and a second fuel injection valve so that fuel is injected from the first fuel injection valve and second fuel injection valve respectively, depending on an EGR rate. The injection rates are determined such that the injection rate of the first fuel injection valve is increased in accordance with the rise of the EGR rate.

  • Patent number: 9097190
    Abstract: An object of this invention is to provide a technology wherein a stratification of an EGR gas with an air-fuel mixture or a fresh air is achieved and capable of introducing the EGR gas in a large quantity, even when an engine load is high as an operation state of an internal combustion engine. With this invention, when a stratified combustion is performed by introducing the EGR gas, the fresh air is supercharged by a compressor, a fresh air blocking valve is closed to block inflow of the fresh air into a first intake port, and a variable valve mechanism opens a first intake valve before opening of a second intake valve, and, thereafter, opens the second intake valve.

  • Patent number: 9046031
    Abstract: A mask portion is provided at a partial area of an intake port at a side opposite to an exhaust port. The mask portion prevents a part of the intake port from being opened when the intake valve is in a low lift state. A top surface of a piston includes a smooth surface. An ECU sets the maximum lift of the intake valve for a variable valve mechanism to an intermediate lift and sets a fuel injection timing for an injector to a compression stroke when an operating range of the engine is a fast idle range. The intermediate lift is an amount of lift at which the intake valve is moved beyond the mask portion and a flow rate of intake air in the partial area is limited relative to a flow rate of the intake air in other areas owing to the mask portion.
