摘要: An electrode arrangement for establishing a sustained electrical arc with a low voltage in which a pair of electrodes are initially brought together and then separated while a current is applied. The sustained arc is adapted to activate fuel flowing past the arc, and the flow is vortical so that the arc is caused to migrate around an annular arc gap space. Several geometric configurations of the electrodes include opposing cylindrical shapes having endwise alligned cavities and a generally tapered portions of one electrode received in a generally tapered opening in the other electrode.

摘要: A test apparatus and method is disclosed for a fuel pump mounted on and driven by an engine, the speed of which is controlled by the pressure of fuel supplied thereto wherein the engine continues to be supplied with fuel from the fuel pump during the test. A fluid circuit is provided which is designed to supply fuel to the engine under controlled pressure to permit the engine speed to be controlled independently of the engine throttle position and to permit the flow rate of the fuel to be adjusted to a predetermined value at which the output pressure of the fuel pump may be measured for calibration purposes. The fluid circuitry and necessary measurement circuitry may be mounted within a small, portable housing to allow for field testing of a fuel pump.

摘要: A variable cam follower (1) is provided for changeable transmission of a lifting movement of a cam to valve train elements allocated to the cam follower (1) in an internal combustion engine. The cam follower (1) includes a hydraulic force transmission device (19) with a variable length pressure space (18), which is bounded by a hollow cylindrical recess (15) of a first cam follower part (3) and by a rod (16) guided in the hollow cylindrical recess (15). The rod is part of a second cam follower part (9) that can move telescopically relative to the first cam follower part (3). The pressure space (18) is closable by a slide (21a, 21b) arranged within the cam follower (1) and acted upon by an adjustable control pressure (p), wherein an opening (23), which extends from the pressure space (18) and opens into a channel (20a, 20b), in which the slide (21a, 21b) runs, is formed in a base (13) of the hollow cylindrical recess (15).

摘要: Transducer housing for mounting in a port in an engine combustion chamber has a metal diaphragm exposed to the combustion gasses. The pressure of the combustion gasses is transferred through an aluminum coupling disc which deflects a simply supported beam member. The beam member is formed of refractory material having epitaxially grown crystalline piezoresistors formed on one surface of the beam member and connected in a bridge circuit and is secured to a ceramic mounting disc. The aluminum coupling disc has a relatively high coefficient of thermal expansion which maintains a preload on the beam member for improved accuracy in spite of the low thermal expansion of the ceramic mounting disc. In an alternate embodiment, an expansion ring made of a material having a relatively high coefficient of thermal expansion is used to support a mounting disc on which the beam member is supported. The high expansion rate of the expansion ring maintains a preload between the beam member and a cup diaphragm by compensating for the relatively low expansion of the ceramic mounting disc.

摘要: A control system for an engine throttle valve actuator uses an actuator position feedback loop with a compensation factor which applies a reverse voltage having an amplitude based on actuator momentum to a DC motor to effectuate an electrical braking action to achieve high speed response with positional accuracy. A separate position limiting feedback loop is used to prevent excessive actuator excursions. The engine throttle valve is controlled to a selected position by using a throttle valve position feedback loop and a compensation factor to provide a feedback signal to a summing junction.
