V-Type engines

A V-type internal combustion engine of the type having a plurality of pistons and piston cylinders positioned in left and right banks, respectively, which are inclined with respect to one another to form a V-shape, the space between said banks being defined as within said V-shape, said engine further having

• a cross flow cylinder head with intake ports opening within said V-shape, exhaust ports in said banks opening to the space outside said V-shape, an injection pump disposed within said V-shape,
• a cam shaft at the apex of said V-shape, said engine comprising;
• auxiliary combustion chambers, one for each piston, disposed in said right and left banks in the vicinity of the inner side of the V-shape above said piston cylinders, respectively, and a plurality of throats for providing communication between said respective cylinders and auxiliary combustion chambers, each said auxiliary chamber being positioned along a first transverse line passing thru the center of the respective cylinder, which transverse line is perpendicular to a second transverse line passing through the centers of all cylinders in a given bank, said first and second transverse line defining a plane substantially parallel with the top and bottom surface of said cylinders in a given bank;
• injection nozzles for each auxiliary combustion chamber respectively, each having its axis disposed in a plane defined by said first transverse line and the axis of a respective cylinder, and inclined at an angle between 0.degree. and 60.degree. with respect to said cylinder axis and having one end projecting into said respective auxiliary combustion chamber and the other end being within said V-shape;
• and further comprising for each cylinder, an intake valve and an exhaust valve, a pair of rocker arms disposed symmetrically about said first traverse line and said auxiliary combustion chamber and above said cylinder and valves, one end of said pair of rockers operatively connected to said intake and exhaust valves, respectively, a pair of push rods operatively engaged at one end thereof to the other ends of said rocker arms, respectively, a pair of cams on said cam shaft for operatively engaging the other ends of said push rods, respectively, the said cams for all said cylinders being arranged on said shaft so that adjacent cams engage push rods existing in opposite banks.
