摘要： This invention relates to the shape of a skirt below the piston head of a piston in an engine cylinder and continuous with it. The skirt has a basic configuration comprising at least two type of elliptical horizontal cross-section with a short axis parallel to said piston pin, and a barrel-shaped vertical cross-section smaller at its top and bottom. A T-shaped projection is also provided on the lateral surfaces of the skirt corresponding to the two ends of the long axis of said ellipse, this projection consisting of a vertical piece and two side pieces situated on either side of the vertical piece. When the engine is running, the skirt comes into contact with the inner surface of the cylinder via this projection. The vertical section of the lower part of the skirt from below the lower edge of the two side pieces to the lower edge of the skirt is inclined toward the inside of said barrel-shaped vertical section so that the skirt is joined smoothly to the projection below the two side pieces. Accumulation of pressure on the edge of the projection is thereby prevented, which reduces frictional resistance and prevents wear between the piston and the cylinder.

摘要： A piston assembly of an internal combustion engine is provided with a piston structure with which oil comsumption is suppressed. A piston of the assembly is disposed inside each cylinder wall of the engine and formed with a top land and the second land. A compression ring groove is formed between the top and second lands. A first chamfered surface is formed at the upper peripheral edge of the second land, and a second chamfered surface larger in width than the first chamfered surface is formed at the lower peripheral edge of the top land. A compression ring having a butt-type ring gap is disposed in the compression ring groove to be slidably contacted with the cylinder wall. With this structure, the oil comsumption is effectively suppressed in both high pressure and negative pressure conditions during operation of the combustion chamber corresponding to the cylinder.

摘要： A spark ignition reciprocatory internal combustion engine with dual induction system is provided in which at low and intermediate loads when only a primary throttle valve within a primary induction system opens, a primary intake port passage within a cylinder head will direct fluid charge into a combustion chamber in a cylinder to swirl therein as a primary intake valve opens, while, at high loads when a secondary throttle valve within a secondary induction system opens also, a secondary intake port passage within the cylinder head will direct fluid charge into the combustion chamber in the cylinder in such a direction as to impede and reduce the swirling motion of the fluid charge from the primary intake port passage as a secondary intake valve opens, thereby to maintain the volumetric efficiency of the engine at a sufficiently high level. The secondary intake valve is operated to open in synchronization with the opening of the primary intake valve. The entire combustion chamber is formed by the clearance volume between the upper surface of a piston and the lower surface of the cylinder head and by a cavity formed in the cylinder head.
