IGNITION DISTRIBUTOR WITH HADIALLY REMOVABLE cou'mc'r MBQHAH'IEM AND TERMINAL MEANS filed Nov. 13, 1%?
rbwwATmRA/EY United States Patent "ice B 90,037 Int. Cl. H01h 19/04, 19/62 US. Cl. 20019 8 Claims ABSTRACT OF THE DISCLOSURE The electric fuel injection system of a multicylinder internal combustion engine receives signals from a signal generating assembly which includes a trip mounted on the shaft of the ignition distributor and a carrier which is removably inserted into the base of the ignition distributor and includes a plate located in a plane which is normal to the shaft. The plate supports two movable contacts which are biased against two stationary contacts. Signals are generated in response to each half revolution of the shaft when the trip causes one of the movable contacts to move away from the associated stationary contact. The plate is withdrawable from the base by moving radially of and away from the shaft.
The present invention relates to multi-cylinder internal combustion engines in general, and more particularly to improvements in internal combustion engines which are provided with electrically operated fuel injection systems. Still more particularly, the invention relates to improvements in internal combustion engines wherein the electronic control unit of the fuel injection system receives signals or impulses from the ignition distributor.
It is already known to provide a. multi-cylinder internal combustion engine with a fuel injection system wherein the operation of electromagnetic fuel injection nozzles is regulated by a control unit which receives signals from the ignition distributor. The control unit comproses a monostable tilting stage which includes a set of transistors.
The tilting stage assumes its unstable condition at least once during each revolution of the engine camshaft to thereby determine the length of intervals during which the fuel injection nozzles remain open. The tilting stage automatically reassumes its stable condition to thereby close the fuel injection nozzles after elapse of an interval whose duration is determined by electric energy storing devices. Certain engines which embody the just outlined fuel injection system are further provided with a signal generator which sends signals to the control unit and is permanently incorporated in the ignition distributor. In a battery-operated ignition distributor, the distributor shaft which receives motion from the engine camshaft carries a trip which operates a switch forming part of the signal generator. Problems arise when the ignition distributor is provided with a spark advance mechanism which must change the position of the distributor cam with reference to the distributor shaft or the position of the breaker plate with reference to the base of the ignition'distributor. The spark advance mechanism renders it difficult to gain access to the switch of the signal generator for the control unit of the fuel injection system. In particular the spark advance mechanism renders it difficult to inspect the signal generator at regular intervals. As a rule, the spark advance mechanism must be dismantled and removed from the base of the ignition distributor in order to afford access to the signal generator.
3,517,142 Patented June 23, 1970 Summary of the invention It is an object of the present invention to provide an ignition distributor for multi-cylinder internal combustion engines which employ electrical fuel injection systems and to provide the ignition distributor with a signal generating assembly for the control unit of the fuel injection system whereby the ignition distributor and the signal generating assembly are constructed and assembled in such a way that the latter can be readily detached from the ignition distributor without necessitating even partial dismantling of the remaining parts of the ignition distributor.
Another object of the invention is to provide an ignition distributor which is provided with a spark advance mechanism and wherein the signal generating assembly for the fuel injection system is installed in such a way that its parts can be removed from the base of the ignition distributor without necessitating even partial dismantling of the spark advance mechanism.
A further object of the invention is to provide a removable signal generating assembly which can be used to transmit signals to the control units of presently known electrical fuel injection systems for multi-cylinder internal combustion engines.
The invention is embodied in an ignition distributor for multi-cylinder internal combustion engines of the type having an electrically controlled fuel injection system which preferably includes known electromagnetically operated fuel injection nozzles arranged to open in response to impulses transmitted by the transistorized output stage of an electronic control unit. The ignition distributor comprises a customary base which is provided with an opening, a distributor shaft rotatably mounted in a bushing provided in the base and arranged to operated a customary rotor through the intermediary of a distributor cam and a spark advance mechanism, and a novel signal generating assembly for the injection system of the engine. The signal generating assembly includes actuating means which preferably resembles a trip or cam mounted on the distributor shaft in the base of the ignition distributor, a preferably plate-like carrier which is removably inserted into the opening of the base, and switch means including stationary contact means mounted on the carrier and movable contact means provided on the carrier and operable by the trip to eifect opening and closing of the switch means in predetermined angular positions of the distributor shaft. The switch means preferably includes two switches alternately open in response to each half revolution of the distributor shaft.
The carrier is inserted into the base in a manner similar to that in which a drawer is inserted into a table and is withdrawable radially outwardly of and away from the distributor shaft. In order to properly locate the movable contacts with reference to the tip on the distributor shaft, the carrier is provided with a cutout or recess which receives the bushing for the distributor shaft when the carrier is fully inserted into the base of the ignition distributor. Terminals which are connected to the stationary and movable contacts of the switch means extend into a socket provided on the carrier, and the socket can be coupled with a plug which contains conductors arranged to transmit signals to the control unit of the fuel injection system.
The novel features which are considered as characteristic of the invention are set forth in particular in the appended claims. The improved ignition distributor itself, however, both as to its construction and its mode of operation, together with additional features and advantages thereof, will be best understood upon perusal of the following detailed description of a specific embodiment with reference to the accompanying drawing.
Brief description of the drawing Description of the preferred embodiment The ignition distributor of FIG. 1 comprises a cast aluminum base or housing 1 provided with a tubular extension or neck 2 which can be inserted into the block of a multi cylinder internal combustion engine. The neck 2 accommodates a distributor shaft which is rotatable in a bushing 4 and carries at its outer end a coupling 3 which can be driven by a gear on the engine camshaft. The shaft 5 extends into the base 1 and supports a weight carrying plate 6a .for advance Weights 6 which form part of a spark advance mechanism serving to control a distributor cam 7. The cam 7 cooperates with a distributor lever 8 supported by a breaker plate 9 which is installed in the base 1. The breaker plate 9 also carries a fixed contact 10 which cooperates with the distributor lever 8.
The open end of the base 1 is connected with a plastic cap 11 which is secured thereto by two cap clamp springs 12 (only one shown). The cap 11 carries a center high tension terminal 13 which is connected with the secondary winding of an ignition coil (not shown) and four outer high tesion termials 14 connected to the engine spark plugs. A rotor 15 of plastic material rotates with the distributor cam 7 and carries an embedded shielding resistor 16 which directs the high voltage surges from the ignition coil to the individual outer terminals 14.
The heretofore described parts of the ignition distributor are well known in the art. In addition, the ignition distributor serves as a means for transmitting signals to the fuel injection nozzles of the electrical fuel injection system for the internal combustion engine. The signal generator assembly of the ignition distributor comprises a tubular actuating cam or trip 20 which is mounted on the distributor shaft 5 and cooperates with two pivotable or movable contacts 21, 22. The contacts 21, 22 are afiixed to blocks 23 of insulating material and are electrically connected to leaf springs by means of rivets 24 passing through the respective blocks 23. This is best shown in FIG. 2. The leaf springs 25 urge the projections or lobes 26 of insulating blocks 23 against the periphery of the trip 20 and to thereby hold the movable contacts 21, 22 in engagement with stationary contacts 27. When the distributor shaft 5 rotates, the contacts 21, 22 are moved alternately away from the respective fixed contacts 27 in response to each rotation of the shaft 5 through 180 degrees because the trip 20' pivots the blocks 23. Thus, the signal generator assembly comprises two switches including the movable contacts 21, 22 and the corresponding stationary contacts 27, and each of these switches produces a signal in response to movement of the contact 21 or 22 away from the corresponding stationary contact 27.
In order to permit rapid and convenient inspection of movable contacts 21, 22 and stationary contacts 27 after extended periods of use, the contacts 21, 22, their blocks 23, leaf springs 25 and stationary contacts 27 are supported by a plate-like carrier 30 to form therewith a selfsupporting unit which is best shown in FIG. 3. This unit can be inserted through an opening 1a in the base 1 in a direction radially toward the distributor shaft 5 and can be Withdrawn, not unlike a drawer, in a direction radially of and away from the shaft 5. The carrier 30 is located in a plane which is normal to the axis of the shaft 5 and is provided with two bent-over lugs 3-1 which are coupled to an arcuate bracket 32 whose configuration conforms to the outline of the base 1. This bracket 32 is provided with a plastic Coupling member in the form of a socket 33 which surrounds portions of three substantially L-shaped terminals 34. Each terminal 34 comprises a horizontal leg (as viewed in FIG. 1) which extends toward the distributor shaft 5 when the carrier 30 is inserted into the base 1. The central terminal 34 is connected by means of a short cable 36 with a plate-like, conductor 35 which connects the stationary contacts 27. Each of the two outer terminals 34 is connected with one of the movable contacts 21, 22 through the intermediary of the respective leaf spring 25.
In order to insure that the movable contacts 21, 22 are properly positioned with reference to the actuating trip 20, the carrier 30 is provided with a centrally located centering cutout or recess 40 which accommodates the bushing 4 when the carrier is properly inserted into the base 1. When in fully inserted position, the carrier 30 can be detachably secured to the base 1 by means of two screws 41 or similar fasteners which extend through the bracket 32 and into tapped bores machined into the base. The socket 33 can receive a male coupling member or plug (not shown) which contains conductors connecting the terminals 34 with the input of the electronic control unit in the fuel injection system. Thus, the control unit will receive a signal in response to opening of the switch which includes the movable contact 21 or in response to opening of the switch which includes the movable contact 22.
A fuel injection system which can receive signals from the assembly as shown in the drawing is disclosed in the British patent specification No. 976,340.
Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features which fairly constitute essential characteristics of the generic and specific aspects of our contribution to the art and, therefore, such adaptations should and are intended to be comprehended within the meaning and range of equivalence of the claims.
