Serial No. 237,955.
- This invention relates to internal combustion engines and particularly internal combustion engines of the sleeve valve type and it is an object of the invention to; provide a more economical and better operat ng englne.
It is another object of the invention to provide means for preventing oil pumping in an engine;
It is another object of the invention to pro vide means for preventing oil pumpingcombined with means for producing a Stratified combustion mixture in an internal combustion engine.
Other objects of the invention Wlll appear in the course of the following specification in which the embodiment of my invention which is shown in the accompanying drawings is described. y
In the drawings: I Figure 1 is a view mainly in cross sect on through a cylinder of an internal combustlon engine of the Vauxhall Burt sleeve valve type.
Figu
re 2 is a fragmentary section on the i line 22 of Figure 1.-
The cylinder head is provided with a water jacket 12 which is secured to the block by bolts, such as 13. Water enters the jacket through the D-shaped channel 14, flows through the opening 15 into the funnel 16,
through the funnelinto the depending portion 9 of the cylinder head and then into chan-' nel 17, whence it is returned to the radiator.
The sleeve 11 is given a reciprocatory, combined translational and rotational motion by the pin 18 and in the course of its movement brings the sleeve intake ports (two of which,
19 and 20, are shown) and the sleeve exhaust ports (one of which, 21, is shown) into registration with the proper cylinder intake ports (one of which, 22, is shown) and cylinder exhaust ports (not shown) at'the proper times to allow intake or exhaust.
The cylinder wall 10, it will benoted, is
provided with four lozengeshaped openings 25 in a circumferential groove 26 near its lower end. The excess lubricating oil carried by the sleeve runs'into the groove 26, thence through the openings25 into the spaces 28 and 29 and from these spaces through -communicating openings one "of which is indicated at 30 to the crankcase and thus oil pumpingis prevented.
The sleeve llis provided with four lozenge-shaped openings 27 whichare adapted to register with theopenings 25, in the cylinder wall to admit air to the cylinder at the end of the intake stroke, as shown in'Figures 1 and 2. It is to be noted, as shown in Figure 1, that at this time the top of the piston is below the groove 26 .and, the openings 25 and 27being in registration,air will enter the cylinder from the spaces 28 and 29, which are in communication with the atmosphere, due to the difi'erence in pressure in the cylinder and outside. Admission of air to the cylinder at the end of the intake strokeproduces what is known as a stratified'combustion mixture which tends to make the engine, operate more economically. 1
The openings 27 in the sleeve may be eliminated if desired. If this is done, no air will be admitted to the cylinder through the openings 25 and the remaining structure (the groove 26 and the openings 25 in the cylinder) will. function merely to prevent oil pumping. V Furthermore,the openings 25 and the openings '27, or the openings 27'and the groove 26may be eliminated. "In the former case the groove 26 will operate to hold oil for lubricating the sleeve: In the latter case the openings 25 will operate to'preventpumpingof oil." 7
Theprovision of the means for producing a Stratified combustionmixture inthe enginecylinders-is ,not my invention and I, therefore, do not claim this feature, per'se. My-invention resides in the means for preventing oil pumping and the means for per .7 mitting. the return of the lubricating oil to venting oil pumping and for producing a f of the suction stroke. 7 I 7 -6LfIn' an internal combustion engine which side of the cylinder.
