摘要： When it is determined that the combustion state during the catalyst warm-up control is unstable, an additional ignition is performed on the TDC side relative to the discharge period CP. In a first countermeasure example, an additional ignition period CP2 is provided on the TDC side relative to the ignition period CP1 at the normal time while performing normal ignition and injection. A second countermeasure example is carried out when it is determined that the combustion state is still unstable despite the first countermeasure example. In the second countermeasure example, an additional ignition period CP3 which is a longer period than the additional ignition period CP2 is provided instead of the additional ignition period CP2.

摘要： An intake device of an engine having cylinders is provided. The intake device includes a cylinder head formed with two intake ports per cylinder, and a forced induction system. One of the two intake ports is designed to have a smaller passage cross-sectional area at a throat portion thereof than that of the other intake port, and to cause a strength of a tumble flow strength of intake air formed within a combustion chamber to be stronger when a flow of the intake air into the combustion chamber is assumed to be caused only from the one of the two intake ports, than only from the other intake port. A tumble ratio of the intake air flow within the combustion chamber is a predetermined value or greater when the intake air is forcibly induced and flows into the combustion chamber from the two intake ports.

摘要： A combustion chamber is provided within an internal combustion engine, the chamber bounded by a cylinder bore, a primary end, and a secondary end. The secondary end reciprocates between a TDC position nearest the primary end and a BDC position. Induction and exhaust ports are timed to open and close to transfer air into, and gasses from, the chamber. The chamber becomes fuel stratified when the secondary end is positioned within a stratified distance of the primary end. When stratified, the chamber is comprised of a central region, a perimeter region, and a transfer passageway between regions. A fuel injector at the primary end injects fuel only into the central region and only prior to ignition. The perimeter region pumps air into the central region prior to ignition, creating tumble turbulence. Combustion is initiated near TDC in the central region and concluded near TDC in the transfer passageway.

摘要： An internal-combustion engine includes a cylinder, a piston, a spark plug, and a fuel injection device. The piston includes a top surface, a guiding protrusion, and a cavity. The cavity is provided at a position closer to the fuel injection device than the guiding protrusion when viewed from above the top surface of the piston. The guiding protrusion includes a guiding surface to guide the fuel mist toward the spark plug when the fuel mist is injected from the fuel injection device at a first predetermined timing in a compression stroke. The cavity includes a guiding wall portion to guide the fuel mist toward the spark plug when the fuel mist is injected from the fuel injection device at a timing in the compression stroke between the first predetermined timing and a second predetermined timing.

摘要： 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.
摘要翻译：在与排气口相反的一侧的进气口的局部区域设置有掩模部。当进气门处于低提升状态时，掩模部分防止进气口的一部分打开。活塞的顶面包括光滑的表面。 ECU将可变气门机构的进气门的最大升程设定为中间升程，并且当发动机的运行范围为快速空转范围时，将喷射器的燃料喷射正时设定为压缩冲程。中间升程是进气门移动超过掩模部分的升程量，并且部分区域中的进气的流量相对于由于掩模部分在其它区域中的进气的流量而被限制。
