Powell and James E. Champion, Muskegon, Mich., assignors to Continental Motors Corporation, Muskegon, Mich, a corporation of Virginia Filed Feb. 20, 1961, Ser. No. 90,316 5 Claims. (Cl. 137-4895) Our invention relates to controls for internal combustion engines and more particularly to an automatic manifold pressure regulator for supercharged aircraft engines such as are used in target drones and the like.
In the development of control systems for internal combustion engines, we have aimed toward standards of simplicity without sacrificing efficiency. In pilotless aircraft, requiring automatic controls, many difiiculties are encountered, since conventional automatic systems are generally rather complex, hence expensive to manufacture.
In order to achieve substantial constancy of engine operation, it is generally necessary only to maintain uni form manifold pressure, and the present simplified device is intended to do this through variably relating throttle position to manifold and atmospheric pressures.
An object of the present invention is to facilitate engine control by providing a simplified device for controlling throttle position.
Another object of the invention is to adapt engines to pilotless aircraft by providing a means for maintaining manifold pressure substantially constant.
A further object of the invention is to obtain automatic control of engine operation by providing a means of automatically varying throttle position to obtain substantially uniform manifold pressure during variable oper ating conditions.
For a more complete understanding of the invention, reference may be had to the accompanying drawing illustrating a preferred embodiment of the invention in which like reference characters refer to like parts throughout the several views, and in which FIG. 1 is a diagrammatic view of an air induction system used in a supercharged internal combustion engine.
FIG. 2 is a longitudinal cross-sectional View of the air throttle control shown in FIG. 1.
In FIG. 1, a portion of a preferred air induction system for an internal combustion engine is illustrated as comprising an air intake 10, a throttle valve 11, a supercharger 12, a supercharged air manifold induction means 13, having the throttle valve 11 therein, such that manifold pressure at all times exceeds atmospheric pressure in the manifold 13.
A throttle valve control device 14, having an actuating piston rod 15, is mounted in any suitable fashion so that the piston rod 15 may operate the throttle valve by some means such as through a bellcrank 16 pivoted at 16A, a link 17, and a lever 18 connected to the throttle valve 11 which is pivoted at 11A. Extension of the piston rod 15 acts to open the throttle valve 17, while retraction acts to close it.
The control device 14, as shown in FIG. 2, preferably comprises a cylindrical two-part housing 20 having a mounting bracket 21 secured thereto, and an inner wall 22 secured intermediate the ends 23 and 24, dividing the interior into a manifold pressure chamber 25 and a control chamber 26 which is further divided by means of a piston 27 into a regulating pressure compartment 26A and an atmospheric pressure compartment 26B.
The chamber 25 is openly connected, by any means such as a conduit 28 to the manifold 13 downstream of the throttle valve 11, transmitting manifold pressure into the chamber 25 and through a variable metering valve 29 into the regulating pressure compartment 26A.
The compartment 26B is openly connected, through a port 30 or the like, to the atmosphere. A spring 31 or other suitable means, in the compartment 26B, biases the piston 27 toward the wall 22, but for practical purposes the piston can be considered as tending to maintain a position of balance determined by the differential between the pressures in compartments 26A and 26B; that is, manifold and atmospheric pressures.
Changes in position due to variations of pressure differential are transmitted through the piston rod 15, to which the piston 27 is secured, to the throttle valve 11.
Although during engine operation the valve 29 will normally be open to some degree, when it does close, the pressure in compartment 26A may leak out through passages 31 and 32 provided in the piston rod 15.
In order to control the admission of manifold pressure into the compartment 26A so that the piston 27 may attain a position of balance, the valve 29 is made variable with respect to variations of manifold pressure.
A sealed spring loaded bellows 35 is provided in the chamber 25, one end being mounted on a stud 36 carried by the housing end wall 24 and threaded to provide axial adjustment of the bellows 35. The valve 29 is cylindrical metering pin as shown, having an axial passage 37 openly connected by a transverse passage 38 with the chamber 25 and by a second transverse passage 39 with an annular groove 40, the valve 29 fitting through a bore 41 in the wall 22.
The end of the valve 29 has a tapered end 42. As manifold pressure in the chamber 25 varies, the bellows 35 collapses and expands to move the valve 29 axially in the bore 41, variably admitting manifold pressure to the compartment 26A past the end 42.
Thus, when manifold pressure decreases, the bellows 35 expands, actuating the valve 29 toward the open position, admitting manifold pressure to the compartment 26A. This pressure, in the supercharged engine, being higher than the atmospheric pressure in the compartment 26B, the piston 27 moves to the right, extending the piston rod which, as previously described, opens the throttle. Manifold pressure then increases and the bellows 35 will collapse, actuating the valve 29 toward the closed position, restricting admission of manifold pressure into the compartment 26A. The piston 27 will thus automatically seek that position of balance previously described at which the differential between manifold pressure and atmospheric pressure plus spring pressure, in compartments 26A and 26B respectively, is zero.
This position of balance may be adjusted by turning the threaded stud 36 to vary the neutral position of the valve 29, which will provide calibration of the control device 14 to any desired manifold pressure consistent with optimum engine performance.
Although we have described only one preferred embodiment of our invention, it will be apparent to one skilled in the art to which the invention pertains that various changes and modifications may be made therein without departing from the spirit of the invention or the scope of the appended claims.
