摘要： This disclosure deals with apparatus for adjusting the timing of injection in an internal combustion engine wherein the fuel system includes unit injectors. The injector for each combustion chamber of the engine is actuated to inject fuel by a cam-follower-linkage mechanism that operates in time relation with the movement of the pistons of the engine. Each such mechanism includes a cam which is rotated in synchronism with the pistons of the engine, a pivotable cam follower which rides on the cam, and a linkage which connects the follower with an injector. The injector includes a plunger which seats on a cup or nozzle to terminate injection. To adjust the timing of injection, the pivot point of the follower and the angular point of engagement of the follower with the cam are moved. The relation of the cam, the follower and the linkage are arranged such that the movement of the linkage does not materially change the effective travel of the plunger as the timing is changed within a broad range. Consequently, the compression load on the plunger and the injector nozzle remains substantially constant at the termination of injection regardless of changes of the timing.
摘要翻译：本公开涉及用于调节内燃机中的喷射定时的装置，其中燃料系统包括单元喷射器。发动机的每个燃烧室的喷射器被致动以通过与发动机的活塞的运动时间关系地操作的凸轮从动件联动机构来喷射燃料。每个这样的机构包括与发动机的活塞同步旋转的凸轮，骑在凸轮上的可枢转凸轮从动件以及将从动件与喷射器连接的联动装置。喷射器包括一个柱塞，其位于杯子或喷嘴上以终止喷射。为了调整注射时间，从动件的枢转点和从动件与凸轮的接合角度点移动。凸轮，从动件和连杆的关系被布置成使得当定时在宽范围内变化时，连杆的运动不会实质上改变柱塞的有效行程。因此，无论定时的变化如何，在注射终止时，柱塞和喷射器喷嘴上的压缩载荷保持基本恒定。

摘要： The disclosure illustrates a gate type valve which is actuated to block off the exhaust system of an internal combustion engine thereby creating a back pressure which retards rotation of the engine. The gate valve has a series of ports which are selectively uncovered by appropriate inputs to the valve actuator to minimize force requirements when the valve is opened and to limit the amount of engine valve float at relatively high R.P.M.

摘要： This disclosure deals with a variable fluid pressure regulator wherein the level at which the fluid pressure is regulated is adjustable. A member has a flow passage formed therein, and the fluid flows through the passage and out of the member, and a closure is positioned over the opening. The closure is yieldably mounted relative to the member and a spring urges the closure toward the opening. A recess or cavity is formed in the closure, and the fluid flows from the opening, into the recess, and then through a space between the closure and the member. The fluid pressure in the passage is a function of the spring force and the effective area of fluid pressure on the closure, and the effective area comprises the area of the opening plus any area of the recess which lies outside the margin of the opening. The regulated fluid pressure level may be varied by laterally shifting the closure relative to the opening in order to change the effective area.

摘要： The present invention relates to a fuel injector for an internal combustion engine, which utilizes a fuel supply control valve and pilot or servo-valve to control the supply and drain of fuel to and from a main fuel chamber. More particularly, the pilot valve separates and isolates the main fuel chamber from the control valve which controls the fuel supply to the main fuel chamber. In this manner, the control valve can operate without interference from the fuel pressure fluctuations created in the main fuel chamber by a reciprocating plunger.

摘要： A pressure limiting expandable hydraulic tappet is provided for use in an internal combustion engine to selectively vary timing by altering the effective profile of a camshaft. The tappet expands to extend the drive train between the camshaft and a camshaft operated mechanism by enlarging and filling an internal hydraulic chamber with a noncompressible hydraulic fluid via an inlet port. The fluid is retained in the tappet chamber by a control valve until a predetermined pressure is attained, when the valve control opens to exit the pressurized fluid through the inlet port and maintain said predetermined pressure for the duration of the camshaft stroke. The valve control means is responsive to the hydraulic pressure acting on an area differential within the chamber to overcome a selected bias.

摘要： A fuel injection system for a diesel engine. An injection rate control device, such as an auxiliary spring, is connected in line with the conventional injection train which operates the injector plunger in synchronism with the rotation of the camshaft. When an auxiliary spring is used as the injection rate control device, the auxiliary spring has a lower spring rate than that of the injection train so that the injector plunger is advanced at a different rate when it is under the control of the auxiliary spring. Means are included for rendering the auxiliary spring ineffective during a portion of the plunger advancement so that the rate of plunger advancement is controlled by the auxiliary spring during the initial part of the advancing stroke, and by the conventional part of the injection train during the balance of the advancing stroke. The auxiliary spring automatically varies ignition timing and injection rate as a function of engine speed and/or load.

摘要： A modulated exhaust braking apparatus is provided for use on a motor vehicle engine. The apparatus is connected to and forms a part of the engine exhaust system and produces minimum back pressure when the apparatus is in its open position. The apparatus includes a first chamber which separates an exhaust duct into two sections. One section is connected to an inlet for the first chamber and the second section of the duct is connected to an outlet formed in the first chamber. A closure member is adjustably mounted within the first chamber and, when in one position of adjustment, closes off communication within the first chamber between the inlet and outlet thereof. Pneumatic pressure responsive means is adjustably mounted within a second chamber separated from the first chamber. Adjustment of the closure member to a close off position and retention thereof in said close off position is dependent upon regulated pneumatic pressure exerted on the pressure responsive means. Adjustment of the closure member from a close off position to an open position wherein the inlet and outlet are in communication with one another is dependent upon the pressure of the exhaust gas upstream of the first chamber inlet.

摘要： In accordance with preferred embodiments, a fuel injector has a gas accumulator of a volume that is at least ten times the maximum amount of fuel which would have to be injectable thereby, and a solenoid operated poppet valve with an end face that opens into the combustion cylinder and is shaped to deflect a portion of the fuel injected into direct contact with the ignition plug. In a first embodiment, using a variable fuel supply, an electronic control unit (ECU) controls the injection timing to inject the compressed gas into the cylinders as each's piston nears its top dead center (TDC) position to obtain diesel engine-like efficiencies (.eta.=45%) so long as the compressed gas supply pressure is sufficiently high (at least approximately 2,000 psi), and when the compressed gas supply pressure becomes too low for high efficiency operation (i.e., below 2,000 psi), the ECU changes the manner of operation so that fuel is injected into the engine when piston is near its bottom dead center position (BDC) so that it can be premixed with air prior to ignition to produce gasoline engine-like efficiencies (.eta.=35%).

摘要： A unit fuel injector for a fuel injection system for an internal combustion engine is described that is reciprocably driven from a camshaft by a drive train, and the unit injector includes a device for controlling the rate of fuel injection into an engine cylinder. The rate control device operates to divert or bleed off a quantity of fuel from the main metering chamber of an open-nozzle type fuel injector during an initial phase of injection, and the diverted fuel is returned to the metering chamber at a later phase in the injector operation. The rate control device includes an auxiliary metering chamber which receives the diverted fuel via an auxiliary passageway. An auxiliary plunger is mounted within the auxiliary metering chamber. A biasing device such as a helical spring or a fluid pressure spring, controls the inward and outward movement of the auxiliary plunger. The biasing device causes the auxiliary plunger to return the diverted fuel to the metering chamber when the pressure of the auxiliary plunger biasing device exceeds the fluid pressure within the metering chamber. In one embodiment, the biasing device is adjustable by controlling a control pressure of a fluid pressure spring.
