This invention relates to a novel and improved internal combustion engine.
One of the main objects of this invention is to provide an improved internal combustion engine which is adapted to handle either high grade or low grade fuel and to utilize a lean mixture and feed it at a constant flow, so as to provide an uninterrupted power development at a maximum of efliciency.
Another object is to provide a two-cycle engine having means to precompress and preheat the fuel mixture before feeding it to the combustion cylinder, whereby to utilize a positive, constant and exactly measured amount of fuel under the various conditions of operation.
A further object is to provide such an engine which is provided with means for storing a certain amount of fuel mixture and admitting it to the combustion cylinder under pressure and heat and at the proper time to materially assist in clearing burnt gases from said cylinder and provide for a proper flushing of the cylinder area and a cleaner and more powerful mixture charge, consequently producing a longer action against the piston and a more powerful piston stroke.
A still further object is to provide such an engine adapted to use high grade or low grade fuel and which can be readily converted into a Diesel type or a semi-Diesel type of engine, by the mere addition or attachment of a preheating chamber to the fuel supply line, which utilizes the engine exhaust gases as the heating agent and from thereon operates the engine under Diesel principle.
These and various other objects and advantages will become apparent from the following description, taken in connection with the accompanying drawings, in which the invention is illustrated in its preferred form of construction, it being understood that various other arrangements and forms of construction may be resorted to for carrying out the objects and purposes of this invention.
In the drawings:
- Fig. l is a side view of a two-cycle engine illustrating my invention in its preferred form of construction.
Fig. 2 is a vertical sectional View thereof, taken along line 22 of Fig. 1.
Fig. 3 is a partial side view showing my improved engine with the addition of a preheating chamber through which a part of the fuel supply line extends, thereby adapting this invention for a Diesel type of engine.
In the drawings my invention is illustrated in its preferred form of construction which comprises a combustion or ignition cylinder l wherein the fuel mixture is ignited and which contains a piston II; and a supercharging cylinder l2 wherein the fuel mixture is precompressed and 1935, Serial No. 15,533
preheated and which contains a piston I3 also a receiving chamber I l which operatively connects the two cylinders and is of proper size to store the required and definite amount of precompressed and preheated fuel mixture received from cylinder 52 and to admitthe same to cylinder Ill under the proper temperature and pressure to provide a positive feed and utilize all the available power stroke of piston l l.
The fuel charge is conducted through fuel supply line it, from a suitable source of supply, to carburetor I1, and the premixed charge then enters mixing chamber l8 wherefrom it passes through conduit !9 which extends through a prewarming compartment 28 to intake manifold 2|, wherefrom the charge flows to a passage or chamber 22 provided at the upper end of cylinder l2. A valve element 23 closes the opening in valve seat 24 and is movable therefrom into cylinder 12 to admit fuel charge thereto from passage 22.
The downstroke of piston l3 compels valve element 23 tomove from its seat and admit the fuel charge by suction from passage 22 to supercharging cylinder l2, thereby depressing spring 25 on valve stem 26. When the downstroke of piston i3 is completed valve 23 automatically moves to closed position by the action of spring 25, and the mixing is confined in cylinder l2.
A valve element 29 is moved by a compression spring 3!] to its closed position on valve seat 3i thereby closing the valve opening and stopping communication between cylinder l2 and storage passage M. This spring is of sufficient strength to retain the valve closed during the main upward or return stroke of piston l3, so that the mixture in the supercharging cylinder will be compressed to the desired extent, and so that it will open when a predetermined pressure of the mixture is reached.
The fuel and air mixture is preheated and vaporized by such compression in the supercharging cylinder, and it then enters the receiving and storage passage M, where it maintains its pressure and heat created by the compression stroke of supercharging piston l3 in cylinder l2. At the end of the upward stroke of piston l3 valve 29 closes due to the pressure of spring as, and the preheated and precompressed mixture is retained in passage 14.
A mechanical valve 34 closes a valve seat 35 provided in the upper end of cylinder ill, thereby stopping communication between said cylinder and storage chamber l4. This valve is normally held closed by a spring 35, provided on valve stem 31, until it is opened mechanically by the valve actuating elements.
In the form illustrated these actuating eleto a rod H by threaded means 42, whereby to adjust the length of the rod. The upper end of said rod actuates a lever 43 pivoted at 54 on a bracket 45 provided on the cylinder casing, while the free end of lever 43 engages valve stem 31 whereby to open valve 34 against the action of spring 36, so as to open the valve at the proper time for admission of the fuel charge to cylinder H], through the operation of the timing gears 46 and 4'! mounted respectively on cam shaft 353 and crankshaft 48.
An exhaust port 50 is provided in the peripheral wall of cylinder I 0, substantially midway of its length, and communicates through a channel with exhaust manifold 52. A pipe 53 extends from the exhaust manifold to the prewarming compartment 20 and forms a bypass to conduct hot exhaust gases into said compartment for heating the mixture in conduit i9 which extends through said compartment.
A piston rod GI is pivoted to piston H and is rotatably mounted on the crank pin 62 of crankshaft 48; and a piston rod 63 is pivoted to piston l3 and is pivotally connected to a bracket arm 64 which is offset or extends laterally from rod 6i. Such offset connection of rod 53 of the supercharging piston to rod 6! of the main piston provides a definite advance of stroke of the former relative to the latter. This permits a dependable control of admission of fuel through either the automatic valve or the mechanical valve, for governing the interrelation with the combustion chamber and the timing of the power stroke and the precompression stroke, arranging same to be adjustable for different fuel mixtures.
A safety valve is provided to prevent accumulation of excessive pressure in storage chamber 14. This comprises a channel or bypass 65 formed in the top part of cylinder 52, connecting chamber [4 with chamber 22. Said bypass is normally held closed by a valve element 65 pressed by a spring 6'! against its valve seat 58. The tension of the spring and the opening of said valve is adjustable by means of an adjust-- ing nut 69, so that the valve will open to admit mixture from chamber M into chamber 22 when the pressure in chamber l4 becomes too great,
due to improper functioning of valves 29 and 34, etc.
Cooling jackets 1'0 are provided around the two cylinders and communicate with a cooling jacket H provided around the storage chamber i l, while a hot water return pipe 12 conducts the hot water from said jackets to a suitable radiator (not shown).
An air intake and filter "I3 is also provided on carburetor I! for admitting clean air thereto.
In Fig. 3 I have iliustratcd how this improved construction is adapted and arranged to be read ily convertible from a light fuel or gasoline consuming engine to a Diesel or semi-Diesel type of engine for consuming heavy or low grades of fuel. As is indicated in the drawings, the various parts shown in Fig. 3 are identical with those shown in Fig. 1, and thereto is applied or added a preheating device, as for example a preheating chamber 15, which is connected with the fuel supply pipe 16 and with the exhaust bypass pipe 53, preferably by having the fuel pipe I6 extend through this chamber and by having the bypass pipe 53 conduct exhaust gases into said chamher, so as to utilize the hot exhaust gas of the engine as the heating agent, and from thereon to operate the engine under Diesel principle.
In order to make this device more easily ccnvertible from a gasoline engine to a Diesel type of engine, a branch pipe 16 is extended from bypass pipe 53 to preheating chamber 75, and a valve H with means '18 for readily operating it is placed at the junction of the two pipes; so that the valve may be readily set to close branch l6 and conduct the hot exhaust gas through the outlet part 53 of bypass 53, when gasoline or light fuel is being used, or outlet 53 may be closed, as shown in Fig. 3, and the hot exhaust gas directed through branch 16, to preheat the heavy fuels which are therewith being used and are then conducted through fuel supply pipe l6 which extends through said chamber, for operating the engine under Diesel principle.
