TRACY V. BUCKWALTER, OF ALTOONA, PENNSYLVANIA.

INTERNAL-COMBUSTION ENGINE.

Specification of Letters Eatent.

Patented Nov. 6, 1917.

Application filed May 18, 1914. Serial No. 839,422.

T 0 all whom it may concern Be. it known that I, TRACY V. BUCK- WAIHER, a citizen of the United States, residing at Altoona, in the county of Blair and State of Pennsylvania, have invented certain Improvements Relating to Internal- Combustion Engines. of which the following is a specification.

My invention relates to internal c0mbustion engines in which fuel is forced into a charge of highly compressed fluid in the combustion chamber where the fuel is ignited by the heated fluid and combustion effected. These ei'igines. typified by the utilization of highly compressed air for injecting liquid fuel into air heated by compression to a point above that required for igniting the fuel, are simplified in construction and operation and operated more economically by means of my improvements, which contemplate the utilization of the heat in the Waste gases discharged from the combustion chamberfor evaporating water and utilizes the steam thus generated for carrying the liquid fuel into the fluid compressed in the combustion chamber.

In the accompanying drawings, Figure l is a longitudinal sectional View of an in ternal combustion engine to which my improvements are applicable; Fig. 2 is an on largcd elevation of the engine having my improvements combined therewith; Fig. 3 is a part sectional elevation representing a second view of the construction shown in Fig. 2; F ig. 4 is an enlarged sectional view taken on the line H of Fig. 3; Fig. 5 is an enlarged sectional view taken on the line 55 of Fig. 3; Fig. 6 is a sectional view of the atomizing disk taken on the line 6fi of Fig. 5; Fig. 7 is a peripheral view of the atomizing disk; and Fig. 8 is an enlarged sectional view taken on the line 8--8 of Fig, 5. e

The mechanism illustrated in the 'accom-- panying drawin comprises the conventional engine cylinder 1 containing the piston 2 connected by the pitman 3 with the crank shaft 4; the cylinder being provided with the passage 5 having the port 6 through which air is admitted back of the piston in the forward position thereof, the passage 7 having the, port 8 through which air is forced into the cylinder in the backward movement of the piston, and the port 9 connected with a conduit 10 through which the heated I products of combustion are dis inlet 2 charged from the cylinder in the backward position of the piston.

In accordance with my invention, an eccentric 11 on the shaft l operates a pitman 12 to reciprocate a head 13 fixed to

plungers

14 and 15 which act in the respective chambers ldand 17 of a pump 18.

A conduit 19 delivers fluid fuel to the chamber 16 under control of acheck alve 20 which controls the port 21, and a conduit 22 delivers the fluid fuel from the chamber through the inlet 23 of the injector 23 which discharges into the top of the cylinder 1, the discharge from the latter conduit back to the pump being prevented by a check valve 24 which controls the port 25.

A conduit 26. controlled by a. check valve 2'7 normally seated on the port 28, delivers water to the chamber 17, which discharges through the port 29, controlled by thecheck valve 30, to the conduit 31 connected with the inlet 23* of the injector 23 back of the The inlet 23* communicates with a circular channel 23 which discharges through the radial apertures 23 to the injector chamber.

Coils 3-1 of the conduit 31 are contained in a burned tube 32 through which flame is discharged from a nozzle or torch 33; and coils 31 of the conduit 31 are contained in the conduit 10 and heated by the waste products of combustion discharged from the engine cylinder 1. Y

The injector 23 contains an atomizing ring or disk 34 provided with a peripheral channel 342 in registration with the fuel inlet 23 the small radial passages 34 which communicate with the channel 34, and the axial passage 34 which communicates with the passages 34'.

A valve 35 controls the injectors aperture- 232 by which it discharges into the cylinder 1', and passes freely through the aperture 34 so that fluid will flow therethrough, the shank of the valve passing through the packing 36 held in the rear of the injector. shank of the valve 35 and engages a coiled spring 38 supported by a yoke 39 fixed to A nut 37 is engaged on the the injector, the spring acting through the I nut on the valve to effect the closure of the aperture 23. A crank lever 40, fulcrumed on the bracket all is connected by the rod 42 with the head 13 and is adapted to act. upon the nut 37 in the upward movement of the head to Withdraw the valve 35 from the port 23, the valve being seated lay the spring as the head descends.

In the operation oi the engine, the oscillation of the

pitmen

3 and 12 by the crank shaft 4:, with resulting reciprocation of the piston 2 and plungers 1e; and 15 are synchronized so that the plungers l4 and 15 are drawn back in the

respective chambers

16 and 17, efi'ecting the delivery of fuel oil and Water to the respective chambers, as the pisten 2 moves back in the cylinder 1; and as the piston moves forward in its cylinder, effecting the compression of air in front of it, the plungers force the oil and water through the

respective conduits

22 and 31, the Water being vaporized in passing through the coils 31* heated by the burner 32 in starting and inpassing through the coils 31 heated by the Waste gases flowing through the conduit 10 in the normal. operation of the engine. The oil is delivered from the conduit 22 through the inlet 23" of the injector into the channel 34E ofthe disk 34 and thence through the passages 3i and 34?, by which it is disseminated. The steam is delivered from the conduit 31 through the inlet of the injector and thence through the channel 23 and passages 23. As the cross head 11} approaches the upper limit of its stroke, the crank le er so caused, by the action oi the rod is, to press against the nut 37 and draw back the valve against the action of the spring 38, whereupon the highly compressed steam. sweeps 28 into the cylinder 1, nited by the heatof the compressed in the cylinder and burns, as the piston moves backward in its Wot 1;; stroke.

The foregoing mode or ope ion and mechanism permits climinatirai from slowcombustion engines of appa 'atus for me compression oi air to such high pie. res from 600 to 1.1900 pounds per square inch; saves the power required to drive such com-- pressing apparatus; utilises portion o' ei'iergy of the exhaust gases in doing a tial Work in a simple manner; permits the use of small unitsiheretoi ore impracticable because of the relatively high cost per unit oi power, due chiefly to the necessity for air compressing apparatus; automatically provides an increase of the steam pressure for spraying fuel into the cylinder with inthe oil through the aperture Where it is 1g crease in load, due to the greater volume of hot gases ayailable for the generation of steam under conditions or increased load; pro i les simple means adapted for starting multiple cylinder engines by the use of a portion of the heating coils in connection with an external supply of heat, aster instance a kerosene torch for the generation of steam for starting; secures the final delivery of the exhaust gases to the atmosphere at comparatively low temperatures due to the absorption of heat from. such gases by the steam coils, and prevents, by the introduction of steam with the fuel, an extremely rapid combustion of the fuel With consequent high pressures, thereby reducing the explosive strains on the engine.
