Patented Aug. 4, 1931 UNITED STATES PATENT OFFICE ANDRE J. MEYER, OF DETROIT, MICHIGAN, ASSIGNOR TO CONTINENTAL MOTORS COB- IORATION, OF DETROIT, MICHIGAN, A CORPORATION OF VIRGINIA INTERNAL COMBUSTION ENGINE Application filed January 30, 1928. Serial No. 250,371.
ency, increased power, and generally im-' proved engine performance.
I have provided a novel cylinder head construction for valve-in-head engines which will provide turbulence for the fuel mix-' ture during the compression of the combustible charge. In engines of the aforesaid type it is customary to locate the valve com bustion chamber over the cylinder, this generalarrangement not affording the desirable turbulence for the fuel mixture.
Further objects of my invention reside in providing an improved valve-in-head engine capable of being manufactured at relatively go low cost. Referring to the accompanying drawings illustrating one embodiment 'of my invention,
' Fig. 1 is a sectional elevation view through 5 a typical cylinder of my engine, and
Fig. 2 is a sectional view at right angles thereto through 2-2 of Fig. 1.
In the drawings reference character A represents the cylinder block having the cylinder 10 and piston 11 reciprocating therein in accordance with conventional or other suitable engine constructions. In Figs. 1 and 2 the piston 11 is shown in its upper limit of travel in which position the piston as face is preferably substantially in the plane of the cylinder block top face 12.
B is the cylinder head carrying the intake and exhaust valves 13 and 14 respectively,
these valves being aligned longitudinally of the engine and operating substantially in the plane longitudinally of the engine containing the cylinder axis, said valves being operated by suitable mechanism C which may be of the usual well known construction. The cylinder head has a machined face 15 seating on the cylinder block face 12 preferably by the interposition of a sealing gasket 16. The cylinder head has a valved combustion chamber 17 generally over the cylinder 10, and is provided with a portion 18 1 travel.
extending inwardly of the cylinder and overlying a portion of the piston face. The under face of the portion 18 is preferably an extension of the face 15 so that a relatively small amount of clearance 19 will be provided between the portion 18 and the piston face with the piston in its upper limit of Such construction further facilitates machining of the head. The overhanging portion 18 may be continued around the combustion chamber as desired for securing the preferred amount of turbulence. In the illustrated embodiment of my invention the portion 18 extends generally along one side of the combustion chamber adjacent the valves 13, 14, the opposite side of the combustion chamber walls preferably being curved at 20 from the valve seats 21 to the face 15 as shown in Fig. 1. Thus a smooth comparatively frictionless flow of the gases past valves 13, 14 is afforded. 'A spark plug 22 is located at a suitable point at a recess 23 in the portion 18. The opposite combustion chamber walls 24 generally below the outer peripheral portions of valves 13, 14 are preferably substantially vertical.
