    Abstract: An internal combustion engine is provided with a roughly concave cylinder head, wherein a ridge descends into the combustion chamber. A first wall is formed from the ridge to a cylinder periphery to form a seat for an air intake valve. A second wall is formed from the ridge to the opposite cylinder periphery to form a seat for one or more exhaust valves. The valves must criss-cross to open/close. The result is a more efficient flow of intake air and exhaust air to and from the combustion chamber which creates more horsepower. A plug compatible cylinder head can be installed on an engine to get added horsepower without a supercharger.

    Abstract: An electro-hydraulic lost motion system for variable valve activation including a master piston and an accumulation piston in a first bore, defining a hydraulic pressure chamber therebetween, in response to rotation of an engine cam. A slave piston in the engine head and hydraulically connected to the pressure chamber opens and closes an engine valve. A servo-valve behind the accumulation piston controls the mobility of the accumulation piston via a fluid control chamber. When the control chamber is made hydraulically rigid, the system actuates the engine valve. When the control chamber is vented through the servo-valve, the accumulation piston is movable in lost motion, preventing the engine valve from opening. All intermediate degrees of valve opening are possible. Preferably, the servo-valve, control chamber, accumulation piston, and a control piston are comprehended in a modular subassembly which may be positioned adjacent the master piston or the slave piston.

    Abstract: A valve structure is disclosed which is mechanically simple and is suited for use in an overhead-valve engine having a hemi-spherical combustion chamber. In the valve structure, inlet valve 3 and exhaust valve 2 are positioned in such a manner that they incline substantially like a "V" in front view to form an acute angle therebetween. Positioned on a first inclined plane U1 are the longitudinal center lines 2a, 4a and 1a of the inlet valve 2, the associated push rod 4 and the associated rocker arm 1, which connects these, respectively. Positioned on a second inclined plane U2 are the longitudinal center lines 3a, 4a and 1a of the exhaust valve 3, the associated push rod 4 and the associated rocker arm 1, which connects these, respectively.

    Abstract: In order to improve the suction efficiency and the cycle efficiency, a heat-insulating engine structure of the invention has a planar and thin-walled piston head surface portion of a ceramics material to be exposed to combustion gases. A combustion chamber is formed not on the side of the piston head but on the side of a cylinder head. Namely, the piston head is defined by the cooperation of a cylinder head bottom wall portion having a lowered central portion and a raised outer peripheral portion and a cylinder liner upper portion including an upper tubular part of a substantially square cross-section and a lower cylindrical part. The cylinder head bottom wall portion has an inclined surface radially upwardly extending from the central portion to the outer peripheral portion. Intake and exhaust valves are associated with valve seats formed in the inclined surface. A fuel injection nozzle is disposed substantially centrally of the cylinder head bottom wall portion. The sides of the square tubular part are operative to agitate a swirl to facilitate uniform mixture of fuel and air thereby assuring that the fuel and air are mixed instantaneously in a zone adjacent to the top dead center of the piston.
