摘要： A piston of an internal combustion engine includes a top part produced from steel and a bottom part, which are integrally bonded in the region of a contact geometry via joining webs by a friction weld to form a structural unit. At least one cooling duct permeated by a coolant is integrated in the piston, wherein a lubricating oil of the internal combustion engine passes as the coolant into an inlet opening via a free jet of an injection nozzle, flows through the cooling duct and leaves the cooling duct via an outlet opening. For the introduction of the coolant into the cooling duct, the inlet opening is assigned a flow pipe which is inserted in the bottom part and protrudes from a cooling duct base, the opening of the flow pipe being arranged above the weld beads of the friction weld.

摘要： An improved wobble piston for an air compressor. The piston has a head integrally connected to a connecting rod. The connecting rod has a free end for connection to a rotating eccentric. The piston head has an internal chamber. Openings are formed through the piston head into the chamber on opposite sides of the connecting rod in a plane perpendicular to the eccentric axis. The location of the chamber openings establishes a flow of cooling air through the chamber as the piston is reciprocated in a cylinder.

摘要： Improvements in a combustion engine performance and reduced temperature of the combustion engine therefore resulting in an increase in the brake thermal efficiency where the pistons move linearly within the combustion cylinder. A pair of one-way clutches is used to convert the reciprocating linear motion into rotary motion without a crank shaft and without friction or power loss in the engine. High pressure oil is used to intercool the piston and the cylinder walls and is used for lubricating the piston ring. This configuration will improve the engine efficiency and reduce emission and result in a low cost engine.
