摘要： A direct-fuel-injection-type spark-ignition internal combustion engine has a fuel injection valve which directly injects fuel into a cylinder. A nozzle hole of the fuel injection valve directs fuel toward an impingement portion of the cylinder bore located opposed to the nozzle hole in a lower section of the cylinder bore so that fuel can be injected into a cavity formed in a top face of a piston from an upper section of the cylinder bore during the latter half of a compression stroke. A cooler located at least in the neighborhood of the impingement portion in the lower section of the cylinder bore has a lower cooling capacity than a cooler located in the neighborhood of the upper section of the cylinder bore. Thus, fuel injected during the latter half of an intake stroke that adheres to the cylinder bore can be effectively gasified.

摘要： A method is presented for improving performance of direct injection spark ignition internal combustion engines at high load conditions by increasing the degree of homogeneity of the air-fuel mixture during the intake stroke of the engine. The improved performance is achieved by adding a deflector designed to reduce intake air impinging upon the fuel spray and deflecting it to the intake side of the combustion chamber, thus facilitating better fuel circulation throughout the combustion chamber. This method improves engine performance at high load engine operating conditions.

摘要： A direct fuel injection, spark-ignition internal combustion engine wherein fuel mainly proceeds toward a spark plug side wall of a cavity along a bottom wall, is deflected by the spark plug side wall and is led to the vicinity of a spark plug. In the engine, the spark plug side wall of the cavity is provided with a deflecting portion inclined toward the inside of the cavity. A first part of the deflecting portion provided on both sides of the spark plug side wall functions to lead the fuel to the vicinity of the spark plug. A second part of the deflecting portion on the central portion of the spark plug side wall functions to lead the fuel to a region neighboring the side of the fuel injection valve from the vicinity of the spark plug.

摘要： An internal combustion engine with controlled ignition and direct ignition. In the internal combustion engine at least one intake duct can generate in a cylinder a flow referred to as “tumble”, at least for certain engine operating phases. Further, a fuel injector is implanted so as to emerge in the cylinder such that the fuel jet tends to be intercepted by the part of the flow circulating in the direction opposite to that of the jet which is directed towards the spark plug.

摘要： In an in-cylinder fuel injection two cycle engine, a combustion chamber dome and a piston cavity are provided in an offset position from a cylinder bore center axis to an exhaust port side, respectively. A spark plug is mounted in a cylinder head such that its electrode is positioned in vicinity of the cylinder bore center axis in the dome. Further, a fuel injector is mounted in the cylinder head such that its injection nozzle is positioned around an outer periphery edge of the dome on the exhaust port side and fuel is injected from the injection nozzle toward the piston cavity. The piston cavity is shaped into a concavely spherical surface so as to direct injected fuel toward the electrode of the spark plug, thereby locally rich, combustible mixture being formed around the spark plug.

摘要： A piston is arranged within a cylinder so as to be movable upwardly and downwardly, a fuel injector is provided at a cylinder head of the cylinder to directly inject fuel into a combustion chamber in the cylinder, and mixture of fuel and air in the combustion chamber is ignited by a spark plug provided at the cylinder head. Scavenging paths and an exhaust port are provided in the cylinder so as to perform scavenging of the combustion chamber and perform exhausting when the piston is moved downwardly by combustion of the mixture. A top portion of the piston is provided with a convex portion with an inclination surface of which inclination extends in a direction of the top portion of the cylinder from an outer periphery of the piston towards a central portion side. The inclination surface of the convex portion is provided as a linear inclination surface of which vertical section contour is linear such that scavenging air from outlet openings of the respective scavenging paths is blown directly on the inclination surface. An angle &thgr; between a ceiling surface at each of the outlet openings of the respective scavenging paths and a perpendicularly crossing surface perpendicularly crossing the axial line of the cylinder is made smaller than an angle &agr; between the linear inclination surface on the top portion of the piston and a perpendicularly crossing surface perpendicularly crossing the axial line of the piston.

摘要： An in-cylinder injection type spark-ignition internal combustion engine includes a spark plug, a fuel injection valve, and a piston having a top face and a cavity formed in a first part of the top face. The cavity is located closer to the fuel injection valve with respect to a center of the piston so as to bring the injected fuel toward the spark plug. A space formed in the cylinder at a top dead center of a compression stroke of the piston includes a first space in which a center of the cavity is located, and a second space. The top face of the piston is designed so as to reduce a volumetric difference between the first space and the second space, thereby preventing generation of a strong air stream flowing between the first space and the second space at around the top dead center.

摘要： A method of controlling fuel injection flow in a cylinder of an internal combustion engine. A piston head of the engine is provided with a combined flow redirector and holding bowl recess extending into a top side of the piston head. A fuel injection port is provided in the cylinder in a bottom portion of a combustion chamber of the cylinder located above the top side of the piston head when the piston is at a bottom dead center position. Fuel is injected from the injection port into the recess. The step of injecting comprises injecting the fuel at a first velocity when the engine is operating at a first speed, and injecting the fuel at a second faster velocity when the engine is operating at a second faster speed.
