    Abstract: An engine piston composed of a head and a body separately formed from the head. The head is of ceramic material and the body is light metal or light alloy. The head and the body are connected against axial movement by interengaging means provided on the head and body by rotation of the head relative to the body, and the head and body are then fixed against relative rotation by an anti-turning device, this arrangement preventing development of excessive thermal stress. The piston is of reduced weight, can be mass-produced, and reduces fuel consumption.

    Abstract: Ceramic coatings prevent metal to metal contact between double acting pistons and cylinders. Cylinders and pistons operate in true cylindrical form. Ceramic coated cylinders are gradually brought to operating temperatures while temporary cutting pistons shape the coating to a true cylinder at operating temperature. Cylinders are formed true while cold and cylinders and heads are jacketed with high heat flow conductors so that the cylinders and cylinder heads have uniform operating temperature.

    Abstract: An internal combustion engine having a main combustion chamber, an auxiliary combustion chamber having inlet and outlet ports through which the auxiliary combustion chamber is communicated with the main combustion chamber, an intake port for supplying a lean air/fuel mixture to the main combustion chamber and an auxiliary passage disposed in the intake port for supplying a rich air/fuel mixture. A cylinder head of the engine has a cylindrical recess connecting with the intake port so as to enable the mixtures to flow through the intake port and the recess into the combustion chambers. An intake valve is adapted to seat, at the closed position, a on value seat disposed at the bottom of the recess. The auxiliary combustion chamber is communicated through the inlet port with the recess so that the rich air/fuel mixture is effectively conducted into the auxiliary combustion chamber through the inlet port when the intake valve is at the partially open position and is still positioned within the residual recess.

    Abstract: An auxiliary combustion chamber at least partially embedded in the cylinder head of an internal combustion engine adjacent the intake valve of a main combustion chamber and having a spark plug positioned in the auxiliary chamber and unvalved inlet and outlet ports interconnecting the auxiliary chamber with the main chamber. The air/fuel mixture drawn into the main combustion chamber is deflected by the back surface of the intake valve into the inlet port of the auxiliary combustion chamber toward the spark plug. The auxiliary combustion chamber may include a shell positioned in a cavity in the cylinder head with devices for properly positioning the shell in the cavity and for retaining the shell and preventing it from rotating. A passage is provided for rich air/fuel mixture terminating at the rear surface of the valve, when closed, with refinements of the passage, shape of the inlet port, and main combustion chamber wall facilitating the flow of the rich mixture into the auxiliary combustion chamber by venturi action. The flow of fresh mixture into the auxiliary combustion chamber through suction scavenges the combustion gas remaining from the prior firing sequence.

    Abstract: A production line for mechanically assembling pistons into cylinders of an internal combustion engine block and for automatically mounting the split bearing for each piston connecting rod to the crankshaft of the engine. At one end of the line, the engine block is laid on end with the piston cylinders extending horizontally. A magazine with a generally cylindrical sleeve in alignment with each cylinder bore in the engine is supplied with pistons complete with connecting rods. The connecting rods are positioned facing the top of the engine block. A split bearing end cap for each piston is placed in suitable holders on the sides of the magazine. At one station of the line, a ram automatically pushes one or two pistons into the engine block. A nesting receiver is positioned to receive the end of a connecting rod and guide the bearing end of the rod onto the crankshaft. Thereafter the bottom split bearing end cap is carried to the crankshaft for connection to the top end cap of the connecting rod. This procedure is repeated, as necessary, to fit the remaining pistons into the engine cylinders.

    Abstract: The tendency toward detonation in a spark-ignition internal combustion engine is reduced by adsorbing on an extended surface, such as a wire mesh, the free radicals resulting from oxidation of fuel which otherwise would propagate a chain reaction, the surface being within the combustion chamber, e.g., stationary at the juncture of the cylinder block and head, in spaced relation to the fixed wall of the chamber and positioned between the piston and the ignition device, and having a flame-propagation opening of minor area extending therethrough. The surface may be of material which is catalytic to the oxidation of hydrocarbons and/or N2 to reduce the concentration of CO and/or NOx in the exhaust gas.
