    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 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 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 intake port has a bottom wall having a transverse width which is approximately equal to the diameter of the valve head of the intake valve. The opposed peripheral edges of the bottom wall are located on the extensions of the tanget lines of the outer periphery of the valve head of the intake valve. 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 quantity is calculated on the basis of an engine speed and an engine load and is corrected by an output incremental value determined in accordance with acceleration and deceleration of an engine, at least. The position of an intake throttle valve is detected with regard to whether it is located within a small-opening region, an intermediate-opening region or a large-opening region. When the intake throttle valve is switched over from the small-opening region to the large-opening region, the output incremental value is increased to its maximum value. When the intake throttle valve is switched over from the small-opening region to the intermediate-opening region, the output incremental value is increased such as to gradually approach the maximum value. When the intake throttle valve is switched over from the large-opening region to the small-opening region, the output incremental value is decreased to almost zero. Further, when the intake throttle valve is switched over from the large-opening region to the intermediate-opening region, the output incremental value is gradually attenuated toward almost zero.
