Abstract: In order to reduce the mass of a rocker arm and simultaneously simplify the adjustment of the valve clearances the rocker arm is pivotally mounted on a universal joint so that it may tilt and establish a three point contact between the universal joint and the tops of the two valve stems. By incorporating a hydraulic lifter in the universal joint arrangement constant lash free automatic zero clearance adjustment is rendered possible. Utilizing a roller as a cam follower permits a reduction in valve train friction loss. To prevent the rocker arm from meandering retaining flanges are provided on the rocker arm which envelope the tops of the valve stems.

Abstract: In order to accurately control the operation of the engine while still achieving near optimal swirl rate control, the swirl is controlled by a valve which is separate from the engine throttle valve and which is basically controlled in response to the pressure prevailing across the same. Various operating parameters such as the instant air-fuel ratio of the charge being combusted in the combustion chambers are utilized to modify prerecorded values to those which will induce the best setting for the valve.

Abstract: An internal combustion engine of the reciprocating piston type, which is provided with an exhaust gas recirculation circuit to suppress the formation of NOx and has two or three spark plugs for each combustion chamber. There is a substantial overlap of the opening periods of exhaust and intake valves, so that a portion of the combustion gas is left unexhausted. The combustion chamber has a simple shape such as hemisphere, and the spark gaps of the plural spark plugs are arranged distant from each other in each combustion chamber so as to respectively share approximately equally divided portions of each combustion chamber. The number of the spark plugs is two when the volume of the recirculated exhaust gas, including the unexhausted combustion gas, is about 50% at the maximum of the volume of air admitted into the combustion chamber but three when the recirculated exhaust gas amounts to about 60% of the air at the maximum.

Abstract: An engine is provided with two spark plugs in each combustion chamber to ignite stoichiometric air-fuel mixture mixed with a large proportion of inert gases to lower NOx emission level. The engine is equipped with hydraulic valve lifters which are mechanically connected to intake and exhaust valves to control the valve overlap of the intake and exhaust valves. By the action of the valve lifters, the valve overlaps are increased in the normal driving operation range of the engine to prevent discharge at the terminal stage of exhaust valve opening exhaust gases containing a considerably large amount of hydrocarbons.

Abstract: An internal combustion engine equipped with a catalytic converter for catalytically purifying the exhaust gases discharged from the combustion chambers of the engine. The oxygen-combustibles ratio of the exhaust gases introduced to the catalytic converter is normally controlled to a predetermined level suitable for the reaction within the catalytic converter in response to the composition of the exhaust gases upstream of the catalytic converter. However, the secondary air is continuously supplied to the catalytic converter regardless of the oxygen-combustibles ratio of the exhaust gases during cold start or warmup of the engine to rapidly raise the temperature within the catalytic converter to a level over which the catalytic converter effectively functions.
