摘要： An engine comprising an intake port which has a separating wall projecting downwardly 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.

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 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, two piston pin bosses being formed at opposite sides of the wall portion. The lubricant reservoir defining member is made from a shelf plate main body portion which provides a central lubricant reservoir and two openings on its opposite sides, and two major legs extending from the shelf plate main body portion and each formed with a hole surrounded by an annular portion. Each of the annular portions is engaged with an inner end portion of a corresponding one of the bosses and surrounds the piston pin hole thereof. Thus the lubricant reservoir defining member is securely mounted within the cup shaped piston main body by a reliable and simple construction, with the shelf plate portion generally parallel to and opposing the piston crown and thereby providing a central lubricant reservoir for aiding with the flow of cooling lubricant flowing in and out through the two openings to flow along the underneath of the piston crown.

摘要： An engine comprising an intake port which has a separating wall projecting downwardly 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 and the helical portion. The separating wall extends to near the side wall of the helical portion and defines a narrow passage portion therebetween. The width of the upper wall of the inlet passage portion is gradually reduced towards the narrow passage portion. A rotary valve is arranged in the bypass passage and is actuated by a vacuum-operated diaphragm apparatus. The rotary valve is opened when the amount of air fed into the cylinder of the engine is increased beyond a predetermined value.

摘要： A fuel injection type internal combustion engine comprising a cylinder head having a flat inner wall, and a piston having a flat top face. The flat inner wall and the flat top face form a squish area therebetween. A recess having a lung shaped cross-section is formed in the cylinder head. A shallow groove is formed on the flat inner wall of the cylinder head so as to extend from the intake valve to the recess. The exhaust valve is arranged on the bottom of the recess. A depression connected to the recess is formed on the shallow groove. The spark plug is arranged in the depression. The cylinder head has a portion located between the recess and the intake passage. A fuel injector is arranged in the intake passage. The nozzle of the fuel injector is directed to an inner wall portion of the intake passage, which is located near the recess.

摘要： An engine comprising an intake port which has a separating wall projecting downwardly 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 and the helical portion. A rotary valve is arranged in the inlet portion of the bypass passage so that the axis of the rotary valve is substantially parallel to the axis of the stem of the intake valve. The rotary valve is actuated by a vacuum-operated diaphragm apparatus and is opened when the amount of air fed into the cylinder of the engine is increased beyond a predetermined value.
