| 81 | Distortion control ring for a fuel injector | US365585 | 1994-12-28 | US5503128A | 1996-04-02 | Daniel K. Hickey; Chandresh R. Shah |
| A distortion control ring disposed and connected between a fuel injector body and a clamping device. The distortion control ring is utilized as an intermediary for transmitting a static clamping load from the clamping device to the fuel injector body. The distortion control ring includes a cylindrical shaped main body having a bore extending therethrough between an upper surface and a lower surface. The upper surface of the main body being adapted for mounting a return spring thereon. The lower surface having an annular portion for contacting the fuel injector body. A radial flange is formed on the distortion control ring adjacent to the main body for contacting the clamping device and receiving the static clamping load. The clamping device engages the radial flange at a distance radially outward of where the lower surface of the main body contacts the fuel injector body. This geometric relationship between the radial flange and the lower surface of the main body transfers the static clamping load to a central portion of the fuel injector body. By transferring the static clamping load to a more central portion of the fuel injector body there is a corresponding reduction in the failure rate of fuel injector units. | ||||||
| 82 | Flywheel magnet fuel injection actuator | US263768 | 1994-06-22 | US5476082A | 1995-12-19 | Todd L. Carpenter; Dennis P. Ward |
| The present invention involves a fuel injection system for an internal combustion engine for small utility implements. The engine includes a crankcase with a cylinder bore. The crankcase rotatably supports a crankshaft having a flywheel and a magnet disposed on an outer periphery of the flywheel. The crankshaft is also connected to a reciprocating piston disposed in the cylinder bore. A cylinder head is attached to the crankcase over the cylinder bore, and a fuel injector is disposed in the cylinder head. The fuel injector is in communication with a fuel supply and can inject quantities of fuel into the cylinder head. An induction coil is disposed adjacent to the flywheel, and is coupled to the fuel injector so that rotation of the flywheel generates a pulse on the induction coil that actuates the fuel injector. A fuel pump is driven by the crankshaft and supplies pressurized fuel to the injector. A timing control circuit is connected to the fuel injector and the induction coil to regulate the operation of the fuel injector. The timing control circuit interrupts the induction coil with a pulse width modulated signal when the duration of the actuating pulse exceeds a calculated duration to close the fuel injector. A pressure sensor is disposed in the cylinder head and provides an input to the timing control circuit. | ||||||
| 83 | Continuous high pressure rail deaeration system for fuel injection system | US347627 | 1994-12-01 | US5454359A | 1995-10-03 | Edward H. Howell |
| A continuous deaeration system for use in maintaining a high pressure oil rail of a hydraulically-actuated, electronically-controlled unit fuel injector system free of entrapped air including a tube, one end of which seats in an oil passage leading from the high pressure rail to the front injector of each bank of the engine. The other end of the tube seats within an upper area of the rail, where air may be trapped. The tube thus creates oil flow into the injector from the area of the rail having the air therein, causing the air to be quickly purged through the injector. | ||||||
| 84 | Fuel pump | US244884 | 1994-06-13 | US5427073A | 1995-06-27 | Colin T. Timms; Edward R. Lintott |
| A unit injector for supplying fuel to an internal combustion engine has a bore (21) in which is mounted a pair of plungers (22) extending from the opposite ends of the bore. The plungers are actuated by cams (26) which are mounted on a pair of cam shafts of the engine. | ||||||
| 85 | Internal combustion engine | US285492 | 1994-08-03 | US5419298A | 1995-05-30 | Albert Nolte; Toni Kleinschmidt |
| A fuel injection pump element 15 is mounted in an engine crankcase (1) adjacent its associated cylinder 9, and in substantially parallel orientation thereto so that the high pressure outlet 20 of the injection pump element 15 is close to the injection valve 13 thus permitting a very short injection line 21. Mounting the fuel injection pump element 15 within the crankcase provides a very rigid mechanical support therefor. Use of a very short fuel injection line provides superior hydraulic rigidity as is required for achieving high injection pressures. A special bushing 31 with fuel passage may be used to mount the pump plunger bushing 19. The special bushing 31 may be made of high quality material of low porosity to add strength and avoid fuel leakage that may otherwise occur because of the porosity of the case iron crankcase. | ||||||
| 86 | Fuel injection pump for internal combustion engines | US93823 | 1993-07-20 | US5415533A | 1995-05-16 | Klaus Egger; Kurt Oberklammer; Heinz Popp; Peter Baumgartner; Heinz Rathmayr |
| The invention relates to a fuel injection pump for internal combustion engines, having a pump piston guided in a cylinder bore of a pump body, which pump piston defines a pump work chamber in the cylinder bore and which is axially driven by a cam drive counter to the force of a restoring spring. Each individual cylinder of the engine to be fed is assigned a fuel injection pump, which is inserted into a bore in the engine housing; at the same time, the engine housing serves as the pump housing. In order to limit frictional wear, which is caused by the back-and-forth motion of the roller tappet of the cam drive guided in the engine housing and to easily replace pump parts, a thin-walled slide bush is disposed between the roller tappet and the housing bore. The slide bush is fastened with radial play on the pump body and additionally prevents the roller tappet from slipping out and prevents the preassembled fuel injection pump from falling apart when it is not installed in the housing bore. | ||||||

| A respective fuel injector is provided for each cylinder in a multiple cylinder internal combustion engine. Each fuel injector is located in a respective cylinder head. There are a plurality of fuel passages for each cylinder head. Each fuel passage into the cylinder head is in two sections. One section extends from the space for receiving the fuel injector diagonally with respect to the longitudinal direction of the engine and opens on the transverse surface of the cylinder head and is sealed there. Another passage section extends at an angle to the first passage section and then intersects the lateral side surface of the cylinder head. The two passage sections each comprise a bore in the cylinder head. A wall inside the cylinder head extends between and separates two spaces for receiving inlet valves to the injector and two spaces for receiving exhaust valves from the injector. That wall extends on one side along an air intake port into the cylinder head. On the other side of the wall is a cooling channel which separates the wall from the spaces for the exhaust valve. The wall extends diagonally to the longitudinal direction of the engine, and lines between each of the pairs of valves are essentially diagonal in the same direction as the wall. | ||||||

| 94 | Fuel system for compression ignition engine | US399812 | 1982-07-19 | US4522182A | 1985-06-11 | Dorian F. Mowbray |
| A fuel system for a compression ignition engine includes a body defining a mounting for a fuel injection nozzle. The body also accommodates a reciprocable piston fuel pump having a piston which is actuable by an engine driven cam. The body also defines a surface which in use locates against a surface on the engine cylinder head. The surface is well removed from the bore in the cylinder head of the engine which contains the injection nozzle. In this manner forces applied to the body during operation of the system are applied to the cylinder head of the engine in an area which is sufficient strong to withstand the forces. | ||||||

| In compact vehicle diesel engines, injection pumps are accessible only with difficulty for the purpose of adjusting a starting time of fuel delivery. An adjusting device is provided which includes an adjusting bolt or screw which may easily be reached from a top side of the engine. The adjusting bolt or screw includes a collar which is adapted to engage in a corresponding annular slot provided in an installation flange of a housing of the fuel-injection pump. A threaded portion of the adjusting bolt or screw is threadably accommodated in a threaded member pivotably fastened to the engine. When the adjusting bolt or screw is turned, the injection pump may be rotatably adjusted while a camshaft of the fuel-injection pump, connected to a timing drive of an internal combustion engine, remains in a previous position, thereby varying the start time of fuel delivery of the fuel-injection pump. | ||||||

| A fuel injection pump including a pump body formed with a plunger sliding bore, and a discharge valve mounted on one end portion of the plunger sliding bore corresponding to an upper end portion of a plunger so that said end portion of the plunger sliding bore functions as a guide for the discharge valve. This arrangement enables the plunger barrel and discharge valve guide member of a fuel injection pump of the prior art to be dispensed with and permits the number of the parts of the pump, the size of the pump, the weight of the pump and the production to be reduced. | ||||||
| 99 | Method for angularly correct mounting of a fuel injection pump on an internal combustion engine | US213712 | 1980-12-05 | US4348895A | 1982-09-14 | Max Straubel; Reinhard Schwartz; Ernst Ritter; Ilija Djordjevic; Reinhard Doll |
| A method is proposed in which the injection pump, having been adjusted in terms of the supply quantity and of the supply onset, is provided on a test bench, before being mounted on the internal combustion engine, with an electric pulse transducer, whose mounted position is marked on the injection pump. The pump may also be corrected, at a fixed test rpm, to a set-point value fixed relative to the supply onset signal by means of measuring the signal distance between the supply onset signal of a signal transducer measuring the dynamic supply onset and the rotary-position signal of the pulse transducer. The injection pump, with the camshaft rotated into the rotary position associated with the dynamic supply onset, is mounted on the engine which has been brought with its crankshaft into the associated working position. For testing and if needed correcting the mounted position of the injection pump on the engine, only the signal distance between the rotary-position signal and a dead-center signal of a dead-center transducer secured on the engine is tested and corrected if needed to a fixed set-point value. This measurement can be performed with a conventionally available ignition angle testing device. | ||||||
