ABSTRACT:
An engine for operating a hydraulic motor. Opposed pistons, joined by a common connecting rod operating between two cylinders and between internal combustion valving and ignition components, are used to drive fluid under pressure through a series of cross-over valves to and from a hydraulic motor. Hydraulic fluid is stored and maintained under pressure within the engine cylinders on the other side of the pistons forming an internal combustion engine. A series of embediments within the common connecting rod actuate a matched set of proximity detectors. The proximity detectors, in turn, time the operation of the engines and the operation of the cross-over valves without mechanical linkages. A hydraulic pump is used to start the engine. A blower is used to mix the fuel and air within the engine and to exhaust combustion gasses. The hydraulic motor drives a flywheel to store energy and to dampen the pulsations resulting from the shifting of the cross-over valves and the reciprocating action of the pistons.
