    摘要： The invention comprises at least two independent intake ports 14a, 14b connected to a combustion chamber 15, two intake valves 12a, 12b, and two exhaust valves 13a, 13b. A first fuel injection valve 31a is provided in the first intake port 14a and a second intake control valve 26 is provided for opening and closing the second intake port 14b. When the engine is in the cold condition, the second intake control valve 26 is slightly opened and fuel is injected from the first fuel injection valve 31b. Air-fuel mixture from the first intake port 14a and a smaller amount of fresh air from the second intake port 14b are introduced [into the combustion chamber], and the overall air-fuel ratio inside the combustion chamber is controlled to become slightly lean.

    摘要： A direct fuel injection engine includes a fuel injector so positioned and oriented as to produce a fuel spray whose upper segment reaches the vicinity of a spark plug by a penetrating force of the fuel spray in a low engine speed light load operating region to achieve stratified charge combustion without the aid of tumble. A tumble control valve is operated to strengthen the tumble in a combustion chamber to achieve stratified charge combustion with the aid of tumble in an engine operating region higher in engine speed and/or engine load.

    摘要： A three-valve cylinder head system for a direct-injected spark-ignited (DISI) internal combustion engine. Two inlet ports are positioned in opposite quadrants of the cylinder head, with the fuel injector directing fuel spray into a third quadrant and the exhaust port being positioned in the fourth quadrant. A helicoid intake port and an axially directed intake port generate a swirl-type air flow in the piston cylinder without the aid of flow activation devices. The spark plug is positioned centrally adjacent the longitudinal axis of the cylinder bore. The piston has a bowl in its upper surface with an enlarged downstream area and a harbor area adjacent and past the spark plug which allow the swirl-type air flow to mix with the fuel spray and provide an appropriate fuel air mixture at the spark plug.

    摘要： An intake port configuration (1) for an internal combustion engine wherein the swirl (D) of at least one intake flow entering the combustion chamber via an intake port controlled by an intake valve (5) can be varied, two or more flow paths are associated with at least one intake port, which paths join in the valve region (4), and the flow rate (Q) in at least one of the two flow paths is variable by means of a control element (9), and the two flow paths are constituted by two completely separate intake passages, i.e., a primary passage (2) and a secondary passage (3), the primary passage (2) having a helical form. In order to obtain a high flow rate (Q) at a high swirl level in addition to a wide range over which the swirl D may be varied, the intake valve axis (5a) intersects or is tangent to the secondary passage (3) at least at one point.

    摘要： A spark ignition internal combustion engine is described having a fuel supply system for separating the fuel into two or more continuous streams of fuel fractions having different octane ratings. The engine has an intake system that creates within each combustion chamber a stratified charge comprising at least two regions 113, 123 each containing a higher concentration of respective one of the fuel fractions. Each combustion chamber also has two spark plugs 114, 124 each located in a respective one of the stratified charge regions. The engine ignition system separately controls the spark timings of the spark plugs 114, 124 to vary the pattern of flame propagation through the stratified charge in the combustion chambers in dependence upon the engine operating conditions.

    摘要： An integrated intake manifold assembly including a first poppet valve assembly disposed at the manifold air inlet to regulate air flow into the manifold; a second poppet valve assembly disposed on the manifold to regulate exhaust gas flow into the air intake system; and a bi-directional camshaft with cams for operating simultaneously the manifold vacuum regulating valve and the exhaust gas recirculation valve. The valve bodies are integrally formed in the wall of the intake manifold. The cams are arranged on the shaft to provide optimum synchronized opening and closing of the related valves. When used on a diesel engine, the manifold assembly may further include a swirl valve plate disposed between the manifold and the engine head and having a plurality of ganged swirl valves actuated by levers, connected to the camshaft internally of the manifold and swirl plate, for coordinated motion with the MVR and EGR valves.
