摘要： The first of a pair scissor like rocker arms is pivotally mounted at one end either by way of an adjust screw or a hydraulic lash adjuster and arangement to engage the top of a valve stem at the other. A cam follower which is located between the first and second ends engages a lift cam. The second of the rocker arms is pivotally mounted on the first one and has a closure cam follower at one end and engages the lower face of a retainer which secured to the top of the valve stem by way of a ring type collet. The shaft on which the second rocker arm is pivotally mounted can be provided with eccentric portions which enable the second rocker arm valve clearances to be adjusted separately from the adjustment of the first rocker arm clearance. The arrangement can be adapted to lift and close two valves.

摘要： A system for forcefully igniting a spray of fuel injected into combustion chambers of a diesel engine during engine starting, in place of a conventional glow plug preheating system. The system comprises a plurality of spark plugs located within the respective combustion chambers of the diesel engine and an ignition means for sequentially igniting each of the spark plugs. The system is operated simultaneously with an engine starter motor and at least until the engine has achieved a spontaneous ignition state or most preferably until a fixed interval of time after the engine has achieved the spontaneous ignition state. Detection of the spontaneous ignition state is based on (a) combustion pressure; (b) engine speed; (c) oxygen concentration; (d) engine starter motor actuation (e) exhaust gas temperature; or (f) engine cooling water temperature.

摘要： An ignition plug for an internal combustion engine is disclosed which comprises an elongate electrode means inserted at the center of a plug body, another cylindrical electrode means encircling the electrode means and an insulator means provided between the elongate and cylindrical electrode means and forming a small cavity which is in communication with a combustion chamber. A plasma gas is created in the cavity due to the generation of a spark between the elongate and cylindrical electrode means and is jetted into the combustion chamber to ignite the air-fuel mixture therein. A gap into which the burnt gas is introduced is formed between the insulator means and the cylindrical electrode means so as to warm the wall of the cavity and thereby avoid ignition misfiring.
