(cuesns) atmosphere and carries avent tube 8 having a This is a companion application of an application covering a manually controlled fluid feedin: system filed of even date herewith.
4 This invention relates to a system for distributing fluid through the intake manifold of an internal combustion engine into the cylinders thereof and the fluid can be a motor fuel for starting and runmng the engine, a lubricant for lubricating the upper cylinder parts and areas or solvents and -cleaning compounds for removing any detrimental formation.
The object of my invention is to provide automatic means for controlling the fluid feeding system whereby thefeeding of fluid can be controlled by the engine temperature.
Another object of my invention is to' provide a fluid feeding system which will initially and constantly feed a predetermined amount of fluid to the engine for a period of time and thereafter feed intermittently a predetermined amount of fluid into the cylinders of an internal combustion' engine.
In the drawing:
Fig. 1 is a diagram illustrating the application of my invention to an internal combustion en- \Y K ne.
Fig. 2 is a vertical section. x
In my companion application I have shown and described a fluid feeding system constructed substantially the same as disclosed in this appli-' cation with the exception that manual means is provided for controlling the system while in this application I have provided automatic means for controlling the system.
In the drawing I indicates an internal combustion engine and 2 the intake manifold thereof the engine being disposed in a motor vehicle, motor boat or the like, it of course ,being understood that my fluid feedi'ng system can be used in connection with a stationary engine.
. My improved fluid feeding system for internal combustion engines comprises a reservoir 3 of any desired shape and size which is preferably arranged adjacent the engine as herein shown. Disposed in the reservoir 3 adjacent its bottom is a measuring chamber 4 provided with a strainer 4' in its bottom and having disposed therein a block providedwith a well 5 of a predetermined size. The well I is provided with a calibrated inlet opening 6 in its bottom through which the fluid passes from the reservoir into the measuring chamber.
The reservoir I is provided with a removable cover 8' and is provided with a vent 'i to the vent opening 9 in communication with the inside of the reservoir 3. The lower end of the vent tube 8 extends through the top of the measuring chamber so as to vent the same, as will be later described.
Disposed in the measuring chamber is a pickup tube It the lower end of which is arranged in the top of the well 5 and the tube extends upwardly into the cover. 31 of the reservoir 3 and is connected to. the inlet of a valve casing ll disposed adjacent the engine by a tube It from which extends a tube, "connected to the intake 2 of the engine. i. The pickup tube iii, tube i0, valve casing ii and tube i2 forms a conduit extending from the measuring chamber 4 to the intake manifold of the engine through which at intervals fluid and air is adapted to be drawn by the partial vacuum created in the manifold when the engine is running. The valve casing II is provided with a reciprocating valve II for closing the outlet thereof but is normally held open by a thermostat i4 herein shown disposed in the valve casing, but it is of course understood that the thermostat can be disposed outside to be affected directly or indirectly by engine temperature. I wish it to be clearly understood that the valve can be operated by any kind of a temperature actuated device placed in the most desired position in respect to the internal combustion engine so as to be affected by the heat generated by said engine. As for examples the valve casing containing the thermostat could be placed in the cooling system of the engine; the exhaust system of the engine or carried directly to the engine so that when the enk e is cold the fluid .will be fed to the engine until the temperature of the motor causes the temperature actuated device to close the valve and cut of! communication between the measuring chamber and intake manifold 'The automatic control provides a system for feeding a lubricant to the cylinders of the en ine when the motor is cold and the ordinary lubri--v eating system is not functioning properly.
In the operation of the system due to capillarity the level of the fluid will'have a tendency into the manifold. While this is occurring atmospheric pressure onthe fluid in the reservoir forces the fluid into the measuring chamber through the calibrated inlet until the fluid level is raised to contact with the end of the pickup tube. The system then starts to feed fluid to the manifold until the capillarity is again broken.
It is of course understood that the amount of fluid fed to the engine for any given period of time will be determined by the size of the measuring chamber and the size of the inlet thereto and that the system will initially feed fluid to the engine for a period of time and thereafter intermittently feed fluid to the engine as long as the measuring chamber is in communication with the intake manifold. The opening and closing of the valve starting and stopping the flow of fluid to the engine.
The system can be incorporated in connection with a carburetor for feeding fuel for starting and feeding sufficient fuel to keep the motor running until the carburetor functions properly. This can be accomplished by lowering the end of the pickup tube so that it will be adjacent the inlet opening of the measuring chamber and as the system is controlled by a temperature actuated device the system will cut off automatically when the engine is running properly.
The thermostat can be disposed so that it will be either affected directly or indirectly by the engine temperature.
I claim:
1. The combination of an internal combustion engine having a fuel feeding system and a lubricating system, of an auxiliary liquid feeding system for initially feeding liquid constantly to the engine and thereafter stoppingthe entire supply of auxiliary liquid for predetermined intervals of time while the engine is running, and automatic means for controlling the feeding of the auxiliary liquid.
2. The combination of an internal combustion engine having a fuel feeding system and a lubrieating system, of an auxiliary liquid feeding system for initially feeding liquid constantly to the engine and thereafter stopping the entire supply of auxiliary liquid for predetermined intervals 5 of time while the engine is running, and means actuated by the engine temperature for controlling the feeding of auxiliary liquid.
3. The combination with an internal combustion engine having av fuel feeding system and a lubricating system, of an auxiliary liquid reservoir having a measuring chamber disposed therein provided with a calibrated inlet, a take-up tube extending into said measuring chamber and terminating above the top thereof, a conduit extending from said take-up tube to the intake of the engine whereby initially a predetermined amount of liquid will be constantly drawn into the engine cylinders and thereafter the entire supply of auxiliary liquid will be stopped for predetermined intervals of time while the engine is running.
4. An auxiliary liquid fuel feeding system for an internal combustion engine having a fuel feeding system and a lubricating system com- 5 prising means for initially feeding a predetermined amount of auxiliary liquid constantly to the engine and thereafter stopping the entire supply of auxiliary liquid for predetermined intervals while the engine is running, and means for controlling the feeding of liquid.
5. The combination with an internal-combustion,engine having a fuel feeding system and a lubricating system of an auxiliary intermittent liquid feeding system, a source of liquid supply for said last named system, said auxiliary liquid feeding system being operable at all times during the running of said engine to feed liquid constantly to said engine during predetermined periods, and means controlling the duration of said liquid feeding periods of said system.
