摘要： A valve train for a four-cycle, double overhead camshaft type internal combustion engine includes apparatus for movably supporting the camshafts that mount the cams which operate the intake and exhaust valves respectively so that the camshafts and cams are displaceable with respect to the rocker arms through which the operation of the cams is imparted to the valves. A control system is described that enables the camshaft supporting apparatus to be selectively displaced in response to engine operating conditions, such as rotational speed, so that valve timing and valve lift for the respective valves can be independently varied to produce optimal engine operating characteristics over a wide range of engine operating conditions. A method of operating engine valves in accordance with utilization of the described control system is also disclosed.

摘要： An ignition timing control system for an internal combustion controls the ignition timing in dependence upon an indicative pressure signal representing changes of the inner pressure within the combustion chamber of the engine. The ignition timing control system ceases the feed-back control based on the indicative pressure signal but performs an open loop control under predetermined engine operational conditions.

摘要： Controlled amounts of relatively rich mixture and relatively lean mixture are supplied separately to a combustion chamber of an internal combustion engine. The position of the intake valves, exhaust valve and spark plug are such that the rich mixture tends to remain near the spark plug during the compression stroke of the engine and does not disperse throughout the lean mixture. At the time of ignition enriched mixture near the spark plug ignites readily and the flame propagates into and through the lean mixture which fills the remainder of the combustion chamber. Several constructions are disclosed to achieve the desired mixture ratios for various operating conditions of the engine.

摘要： An internal combustion piston engine has a main combustion chamber and an auxiliary combustion chamber connected by a torch passage, which is tapered end to end, the large end communicating with the main combustion chamber. Lean mixture is supplied to the main combustion chamber and rich mixture is supplied to the auxiliary combustion chamber. A spark plug ignites the mixture in the auxiliary combustion chamber, causing a torch flame to be projected through the tapered torch passage into the main combustion chamber near its center. A suction conduit, smaller in diameter and total area than any portion of the tapered torch passage, extends from a peripheral portion of the main chamber and intersects the tapered torch passage between its ends. Movement of the burning gases through the torch passage aspirates a flow of mixture from the main combustion chamber through the suction conduit into the torch passage.

摘要： Reduction of NO.sub.x emissions from a four-cycle stratified charge internal combustion piston engine is accomplished by (a) spark ignition of a rich mixture in a first chamber containing residual exhaust gas, followed by (b) torch ignition of rich mixture in a second chamber under turbulent conditions, causing (c) torch ignition of a stratified charge in a lean mixture in the main combustion chamber. The result is a reduction in peak temperature in the combustion process, with consequent reduction in NO.sub.x emissions in the engine exhaust gases. Exhaust gas is not recirculated. Said first chamber, which contains residual gas from the previous combustion cycle, contains the spark gap between spark plug electrodes and the spark gap is located near a restricted connection between the first and second chambers and remote from a closed end of the first chamber. Means are provided for changing the volume of said first chamber while the engine is operating, in accordance with variations in load on the engine.

摘要： A valve drive system including mechanisms for varying the timing and lift of intake and exhaust valves in internal combustion engines. In one embodiment, an intake camshaft support member and an exhaust camshaft support member are separately mounted to pivot about axes relative to intake and exhaust rocker arms. The support members include concentric mountings along which the support members together with the cams mounted therein move to selectively advance and retard the valve timing and vary the valve lift. In other embodiments, the camshaft support is unitary in construction for both the intake and exhaust valve train. A variety of adjustments are possible with the several configurations including intake valve closure before bottom dead center during partial load operation.

摘要： An ignition timing control system for an internal combustion engine which controls the ignition timing for one engine cycle in response to the maximum peak position datum of the indicative pressure signal representing the inner pressure within the combustion chamber during the preceding engine cycle. A misfire detecting means is provided which produces a misfire detection signal upon incomplete combustion in the combustion chamber in an engine cycle. The maximum peak position datum is neglected during the engine cycle in which the misfire detection signal appears. At least one pressure sensor is provided for one cylinder in a group of the cylinders having generally the same charging efficiency or volumetric efficiency.
