It is an object of the present invention to provide means for regulating the quantity of fuel meteredfinto each charge during starting of the engine in accordance with an engine temperature. l
It is a further object of the present invention to provide fuel regulating means in a fuel injection systemincluding a member movable to determine the quantity of metered fuel, and means operable as an incidence of operation of the engine starter to move the member to a position as determined by engine temperature to increase the mete'red fuel during starting.
More specifically, it is an object of the present invention to provide a movable regulating member for 'a fuel metering system for an internal combustion engine having an electric starter, solenoid actuated means for biasing said member in a direction to increase the flow of metered fuel during operation of the starter, and abutment means responsive to a temperature condition of the engine for limiting fuel increasing movement of said member.
Other objects and features of the invention will become 7. apparent as the description proceeds, especially when taken in conjunction with the accompanying drawings,
illustrating preferred embodiments of the invention,
injection. The present invention is applied to the type of injection apparatus illustrated in Downing Patent 2,731,-
175 to which reference is made for details of the metering and pumping system.
Described very generally, this construction comprises an elongated cylindrical element 10 rotatable at a speed determined by engine speed in a sleeve 12 having inlet passages 14 and 15 and outlet passages 16 and 17. The inlet passages 14 and 15 are in communication with a threaded opening 18 in a casing 20, and the outlet passages 16 and 17 are in communication with threaded outlet passages 22 and 23 located in the casing. Opening 18 is connected by conduit 18a to a fuel pump 19 which supplies fuel from a tank 21 to opening 18.
The element 10 has a longitudinally extending cylindrical opening 24 provided adjacent one end with a fixed abutment 26 and adjacent its other end with a movable abutment 28. Intermediate the abutments 26 and 28 is a shuttle 30.
By rotation of the element 10, pressure is admitted alternately to the cylinder 24 at opposite sides of the and movable abutments.
Patented Dec 20, 1960 tity of. fuel. discharged during movement of the shuttle is of course determined by the spacing between the fixed At the same time, movement of the shuttle 3t? downwardly admits a metered quantity .of fuel into the cylinder above the shuttle, again as determined by the spacing between the abutments. Upon further rotation of the element 10, the pressure fluid supplied through the passage 18 enters the cylinder through the passage 15 and shifts the shuttle upwardly, thus expelling a metered quantity of fuel under pressure through the outlet passages 17 and 23. This operation is repeated and at each movement of the shuttle 30, a quantityof fuel metered in accordance with the position of the movable abutment 28 is expelled from one or the other of the outlet passages or ports 22 or 23. It will be understood that ports 22' and 23 are connected by conduits 22a and 23a to separate cylinders or groups of cylinders of an internal combustion engine.
From the foregoing it will be observed that the quantity of fuel discharged at each movement of the shuttle 3% is directly dependent upon the position of the movable abutment 28.
In accordance with the present invention novel means are provided for effecting a desired control of the adjustment of the abutment 28.
The means for effecting adjustment of the abutment I 28 comprises a nose 32 on the end of the movable abutment or on an element connected thereto. v
Associated with the movable abutment 28 is anelongated carriage 34 having rollers 36 and 38 movable along the surface 39 of a movable member 40, and a'fixed surface 41. The carriage 34 has a camming surface 42 which may be straight or have some nonlinear modification, but which in any event is nonparallel to the surface 39 of the member 40. This structure is contained in housing 43.
Connected to the carriage 34 is a link 44 which in turn is connected toa piston 46 movable in a cylinder 48, the interior of the cylinder being connected to the manifold of the internal combustion engine by suitable conduit means (not shown). Accordingly, upon variation in en- 1 gine load or density, the piston 46 is positioned by the joint action of the spring 50, the reduced pressure existing within the cylinder, and the atmospheric pressure acting on the outer surface of the piston. This in turn effects general longitudinal adjustment of the carriage 34. Inasmuch as its surface 42 is not parallel to the surface 39, movement of the carriage 34 effects an adjustment of the, abutment 28 in a direction parallel to the cylinder 24.
Means are also provided for efiecting an adjustment of the member 419 during the interval while the electric starter of the internal combustion engine supplied with fuel by the fuel injection system is being energized. Furthermore, the actual movement of the member 40 is determined by an engine temperature condition so that the fuel mixture may be suitably enriched during cold starting.
In order to accomplish the foregoing the member 40 is mounted for angular adjustment about the axis of a shaft 52 to which the member 40 is keyed or otherwise secured. The shaft 52 is in turn connected to the armature of a rotary solenoid indicated at 54. solenoid when energized is connected to the shaft 52 to apply a counterclockwise rotation thereto, thus effecting counterclockwise angular movement of the member 40.
The amount of movement which is permitted the member 40 when biased in a counterclockwise direction by energization of the rotary solenoid is determined by The rotary b'eing applied to the figure where appropriate.
ture. fuel under relatively high pressure to be supplied during 3 a movable abutment 56. The movable abutment may comprise a relatively heavy bi-metallic member as illustrated, secured at one end as by a screw 58 to a mounting block 60 located within the housing. The interior of the housing 43 is subjected to air at a temperature dependent upon an engine condition as is well understood in the art. Accordingly, during cold weather when the engine is cold the thermostatically adjustable abutment to move said member to a position during operation of 56 moves to a position in which it allows more angular anincidence of energization of the electric starter motor 64 from battery 66.
Referring now to Figure 3 there is illustrated a generally similar arrangement and only the points of difference will be described in detail, likereference numerals In this case the movable member 49 as before, is keyed or otherwise secured to a shaft 52 of a rotary solenoid indicated' generally at 54. However, instead of providing a bi-metallic abutment elementsuch as shown at 56 in .Figure 2, inthis case angular movement of the member 40 is limited by an eccentric cam 70 carried by a shaft 72. The shaft 72 is rotated in accordance with temperature by suitable means such for example as a spirally wound bi-metallic strip. In other words, in this case the cam which operates as the abutment is positioned by a temperature responsive thermostatic device, whereas in the first embodiment of the invention, the temperature responsive thermostatic element itself constituted the abutment.
' In either case, means responsive to the temperature of the engine operate to locate an adjustable abutment Lin a position to determine the quantity of fuel metered into each charge thereof during operation of the engine starter.
The present invention is particularly applicable to a fuel metering and pumping device such as shown in t Figure 2, and fuel is ordinarily supplied to this fuel pumped to the internal combustion engine, it will be observed that during starting fuel is supplied to the internal combustion engine in metered charges and that the quantity of fuel in these charges is increased in accordance with temperature to provide an enriched mix- Inasmuch 'as the operation of the system requires starting, it will of course be understood that the system includes a fuel pump and this conveniently may be an electric fuel pump whose operation is initiated to deliver fuel under the required pressure during starting of the engine.
