摘要： A direct cylinder injection-type spark ignition internal combustion engine is disclosed. The engine comprises a spark plug, a cavity formed in the top surface of a piston, and a fuel injection valve for injecting fuel into the cavity in nearly the shape of a fan having a relatively small thickness. When the fuel injected in nearly the shape of a fan from the fuel injection valve is considered by being divided into a plurality of fuel segments in a radial direction, a side wall of the cavity has a first fuel deflection passage 82a and a second fuel deflection passage 82b for so deflecting at least two of the plurality of fuel segments as to pass near the spark plug. The side wall of the cavity is at least partly provided with a return portion 83 that protrudes toward the inside of the cavity. The first fuel deflection passage is not provided with the return portion 83 or is provided with the return portion having a short protrusion, and the second fuel deflection passage is provided with the return portion 83 having a long protrusion.

摘要： An engine comprising an intake port which has a separating wall projecting downward from the upper wall of the intake port. The separating wall defines a helical portion, an inlet passage portion tangentially connected to the helical portion, and a bypass passage interconnecting the inlet passage portion to the helical portion. A rotary valve is arranged in the bypass passage and actuated by a vacuum operated diaphragm apparatus. The rotary valve is opened when the amount of air fed into the cylinder of an engine is increased beyond a predetermined value. The separating wall has a height which is equal to approximately half the height of the intake port in the vicinity of the rotary valve.

摘要： An internal combustion engine has a cylinder head formed with a wedge shaped cylinder head recess which has on its one side closer to a spark plug a steeply inclined roof surface of about 38.degree. to 40.degree. inclination and on its other side a gently inclined roof surface of about 5.degree. to 20.degree. inclination formed with an intake valve opening, and a piston formed with a piston recess which generally mates with the cylinder head recess and which has on its one side closer to the spark plug an inclined side surface of about 45.degree. inclination. The planar surface portion of the piston crown and the planar surface portion of the cylinder head on opposite sides of the recessed portions mutually define a relatively large squish area on the side of the gently inclined roof surface and a relatively small squish area on the side of the steeply inclined roof surface. A helical port is connected to the intake valve opening so as to generate a swirl flow of air-fuel mixture in the combustion chamber.

摘要： A direct-fuel-injection-type spark-ignition internal combustion engine has an ignition plug, a cavity formed in an upper wall of a cylinder, a fuel injection valve that injects fuel so that most of the fuel strikes a side wall of the cavity at an acute angle with respect to a tangent to the side wall at the point where the fuel strikes it, and a fuel guide portion that is provided in the side wall of the cavity and that guides most of the fuel to the vicinity of the ignition plug. The direct-fuel-injection-type spark-ignition internal combustion engine is able to realize a good stratified charge combustion by reliably positioning a major portion of combustible mixture in the vicinity of the ignition plug at the time of ignition.

摘要： An intake device of an engine comprising an intake passage which is common to a first intake valve and a second intake valve. The intake passage is divided into a first straight passage and a second straight passage by a dividing wall which extends toward a point upstream of the intake passage from a position between the first intake valve and the second intake valve. A downwardly projecting separating wall is formed on the upper wall of the intake passage. The separating wall extends from a position upstream of the upstream end of the dividing wall toward a point upstream of the intake passage along the axis of the first straight passage. An intake control valve is arranged between the separating wall and the side wall of the intake passage, which is located on the second straight passage side.

摘要： A piston assembly for an internal combustion engine is made up from a piston main body and a lubricant reservoir defining member. The piston main body has a cup shaped structure including a crown portion and a hollow cylindrical wall portion joining thereto. The lubricant reservoir defining member includes a shelf plate main body portion formed with first and second depressions which define first and second lubricant reservoirs, and is securely mounted within the cup shaped piston structure with the shelf plate portion generally to and opposing the piston crown. The ratio of the surface area of the first lubricant reservoir to the surface area of the second lubricant reservoir is less than the ratio of the volume of the first lubricant reservoir to the volume of the second lubricant reservoir. Lubricant is supplied more towards the first lubricant reservoir and is drained more from the second reservoir.

摘要： A direct fuel injection-type spark ignition internal combustion engine is disclosed. The engine comprises a spark plug arranged in the upper wall of the cylinder, a fuel injector for directly injecting fuel into the cylinder, and a cavity formed in the top surface of the piston. The cavity has a bottom wall and a spark plug side wall. Fuel injected into the cavity from the fuel injector in the latter half of the compression stroke proceeds on the bottom wall of the cavity so as to be deflected by the spark plug side wall and led to the vicinity of the spark plug. In the engine, the fuel injector injects fuel in the shape of a fan having a relatively small thickness. The cavity has guide walls for preventing fuel from excessively spreading in the direction of width of the fan shape as it proceeds on the bottom wall.
