摘要： An internal combustion engine having a helically-shaped intake port. When the intake manifold vacuum is in the range of about -500 through -250 mmHg, a super lean mixture is fed into the cylinders of the engine. When the intake manifold vacuum is in the range of about -250 through -100 mmHg, a fuel mixture, having the stoichiometric air-fuel ratio, is fed into the cylinders of the engine. When the intake manifold vacuum is smaller than about -100 mmHg, a rich mixture is fed into the cylinders of the engine.

A bypass passage is branched off from the inlet passage portion and connected 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： In a process of mounting a camshaft 20 to a supporting member 10, a shaft body 21 is firstly inserted into a first bearing hole 13F in the front side of the supporting member 10, before the shaft body 21 is axially moved toward the second bearing hole 13R. In order to get a cam lobe 22 through a concave bearing portion 13M in a semicircular arc shape, rotation of the camshaft 20 enables a cam nose 22b to be directed downward, which is opposite from the concave bearing portion 13M. This enables avoiding the interference between the cam nose 22b and the concave bearing portion 13M, even when the curvature radius of the concave bearing portion 13M is reduced. Consequently, reduction of the curvature radius of the concave bearing portion 13M achieves the downsizing of the supporting member 10.
摘要翻译： 在将凸轮轴20安装在支撑部件10上的过程中，在轴体21朝向第二轴承孔轴向移动之前，首先将轴体21插入支撑部件10的前侧的第一轴承孔13F 13R。 为了通过半圆弧形状的凹入轴承部分13M获得凸轮凸角22，凸轮轴20的旋转使得凸轮端头22b能够向下指向与凹入轴承部分13M相反的向下。 这样，即使凹入轴承部13M的曲率半径减小，也能够避免凸轮凸起22b与凹入轴承部13M之间的干涉。 因此，凹入轴承部13M的曲率半径的减小实现了支撑部件10的小型化。

摘要： A cam lobe is formed as a single part, not formed together with a shaft body. The shaft body penetrates through bearing holes, as well as a mounting hole provided in the cam lobe, which is arranged in between adjacent bearing holes. The bearing holes each in a perfect circular shape can be achieved, since there is no need to divide the bearing holes into two semi-circular arc shaped concave portions. Consequently, a camshaft can be supported so as to rotate smoothly.

摘要： A lash adjuster includes a cylindrical bottomed plunger mounted in a cylindrical bottomed body so as to be movable upward and downward and including a high-pressure chamber defined between an underside of the plunger and a bottom wall of the body to reserve an operating oil, a leak path defined by an inner circumference of the body and an outer circumference of the plunger so that the oil reserved in the high-pressure chamber leaks through the leak path with downward movement of the plunger, and a ring-shaped member located between the inner circumference of the body and the outer circumference of the plunger, normally projecting into the leak path and being elastically deformed radially inward or outward with increase in pressure of the oil at the high-pressure chamber side so as to be retreated from the leak path, thereby reducing flow resistance of the oil in the leak path.
