INTERNAL-COMBUSTION ENGINE.
' Specification of Letters Patent.
Application filed January 10, 1917, Serial No. 141,565.
To all whom it may concern: 4,
Be it known that I, PAUL E. NUENKE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Ime provements in Internal-Combustion Engines,
of which 'the following is a specification.
This invention relates to internal-combustion engines of the Diesel type, and more particularly to the fuel injectin means thereof, the invention having for its ob ect to provide a novel and improved means whereby a preliminary explosion of the fuel is effected to completely vaporize the entire charge of oil, which is then thrown into the combustion chamber of the cylinder where it flashes into a flame as it meets the highly heated air in said chamber.
In order that the invention may be better understood, reference is had to the accompanying drawings forming a part of this specification, and in said drawings- Figure l is a vertical section taken through one end of the engine cylinder;
Fig. 2 is an elevation of said cylinder end, and v Fig. 3 is a section on the line 3'-3 of Fig. 1.
Referring specifically to the drawings, the engine cylinder is denoted by the reference character 5, and the reciprocatory piston working therein is shown at (3. The cylin- .der may be of any approved construction and it is provided with a water jacket 7 as usual for cooling the same. The cylinder is shown horizontally supported on a suitable base 8, and it carries a support 9 for a fuel tank 10.
The cylinder 5 is closed at one end by a head 11 which is. provided with a central cavity 12 in its inner face, said cavit being open tothe interior of the cylinder, ack of the piston 6. Back of this cavity, the cylinder head has a seat 18 for an oscillating valve let in the form of a hollow cylinder closed at its ends, one of the end closures being a, screw cap 1:"). From the other end of the valve extends a stem 16 which passes through a guide 17 at the side of the cylinder head, and on the outside of the latter the valve stem has a lever arm 18 for connection with a suitable valve-actuating mechanism, whereby, the valve is oscillated or rocked back and forth on its seat. The valve seat 13 is a cavity formed in the cylinder head 11, and so located that it intersects the cavity 12, with the valve 14 Patented Oct; 2, 1917.
In the cylinder head 11 is also a recess 19 which seats a plug 20 having twolongitudinal passages 21 and 22 respectively, the former being an air delivery passage, and the latter being an oil delivery passage hav: ing a suitable valved connection 23 with the oil reservoir 10. a
In the oil delivery passage 22 is mounted the stem 24 of an oil regulating valve 25 positioned at the inner end of the plug 20 within an enlargement 26 of the passage and adapted to seat on the inner end of said passage. From the cavity 26 aport 27'leads through the cylinder head 11 and .opens through the valve seat 13.
The air delivery passage 21 communicates with a port 28 leading through the cylinder head 11 and opening through the valve seat 13.
In the side of the valve 14 are ports 29 and 30 respectively adapted to register at certain times with the ports 27and 28 to adinit oil and air into the interior of the va ve.
The valve 25is governor-controlled,the stem Let it be assumed that the engine has completed its exhaust strokes and thatthe piston 6 is ready to move outwardly. As this movement of the piston takes place, the valve 1 1 is rocked to bring its ports 29 and 30 into registry with the oil and air delivery ports 27 and 28, whereupon oil and air enters the interior of the valve. Themixture of oil and air, during the suctionstroke and the next, or compression stroke, is confined in the chamber formed inside the valve, due to the restricted area of the ports 31. At a certain point near the end of the compression strultc, the temperature of the air compressed in the cavity 12 and in the hollow I- ie of oscillating valve 14 through ports 31 becomeshigh enough to ignite the fuel mixture in the valve chamber which efiects a thorough atomization, heating and vaporization of the charge, and the same is forcedly ejected through the ports 31 into the cavity 12 where it mixes with the air 'in said cavity and complete combustion of the fuel now takes place to produce the power stroke of the piston. I
ltwill be seen from the foregoing that the valve 14 serves as a reservoir in which a mixture of oil and air is effected by a preliminary explosion resulting from ignition of the oil by the highly heated compressed air. As the valve has a rocking movement it works smooth and wear is reduced to a miniimumon account of the large wearing surface. The valve can be readily removed for inspection or repair. Foreign substances such as sand or grit are eflectually prevented from getting between the valve and its seat, and the valve is therefore not liable to leakage having a portion which projects into said The air intake valve for the cylinder 5 is cavity and is provided with discharge ports of restricted area continuously opening into the cavity, and said valve also being provided with oil and air inlet ports, the inte rior of the valve forming a fuel receiving chamber, and oil and air supply connections to the oil and air inlet ports.
2. in an internal combustion engine of the type described, a cylinder having a combustion chamber, a hollow oscillating valve having discharge ports of restricted area continuously opening into the combustion chamber, and said valve also being provided with oil and air inlet ports, the interior of the valve forming a fuel receiving chamber, and oil and air supply connections to the oil and air inlet ports.
3. In an internal combustion engine of the type described, a cylinder, a head closing the combustion end of the cylinder and having a cavity opening thereinto, a hollow oscillating valve seating in the cylinder head and having a portion which projects into the aforesaid cavity and is provided with discharge ports of restricted area continuously opening into the cavity, and said valve also being provided with oil and air inlet ports, the interior of the valve forming a PAUL E. NUENKE.
