摘要： A rod seal system having a pair of rod seals that form a buffer area between a high pressure area containing working gas and a low pressure area of a heat engine, such as a Stirling cycle engine. A pump that becomes passively charged with working gas at relatively low pressure and which releases working gas at relatively high pressure when actuated is used to force working gas from the buffer area to the high pressure area through a conduit. The working gas may be hydrogen gas and the pump may be a metal hydride pump that is thermally actuated. The low pressure area may contain air and lubricant at atmospheric pressure. A system for separating the lubricant collecting within the buffer area and reintroducing the lubricant into the low pressure area can also be incorporated into the rod seal system.

摘要： A combustor for a heat engine, such as a Stirling cycle heat engine, incorporating a number of nozzles mounted between a pair of plates. Fuel is introduced from above the plates into mixing chambers within the nozzles. Combustion inlet air passing between the plates is introduced into the mixing chambers and create a swirling motion in the fuel/air mixture. The fuel/air mixture passes through an expansion chamber before being discharged to a common combustion chamber. The combustor has been designed to allow the use of high temperature combustion inlet air and to have low NOx emission characteristics.

摘要： A compression ignition internal combustion engine system combusts DME as fuel using high fuel injection pressures (e.g., above 800 bar) and low oxygen concentrations (e.g., below 17%, through high levels of EGR), thereby resulting in simultaneously very low NOx and PM engine-out emissions.

摘要： A variable displacement hydraulic/pump motor has a yoke with a pair of shafts aligned to define a yoke pivot axis and connected to a valve plate therebetween having intake and discharge apertures. A rotatable cylinder barrel has piston cylinders open at one end to receive a piston head and opening through fluid ports at another end, flush against the valve plate surface. A drive block is mounted on an input/output shaft for rotation about a central axis of rotation inclined at an angle relative to the longitudinal axis of the cylinder barrel which may be changed by a drive engaging the yoke at a point near its pivot axis. Loads on bushings supporting the yoke shafts are reduced by providing radially extending fluid ports in the shafts and in communication with the intake and discharge apertures of the valve plate.

摘要： To reduce emissions at higher engine loads and speeds, methanol fuel is port-injected with charge-air into a diesel engine, and diesel fuel is then direct-injected to initiate combustion. The charge-air has a reduced oxygen concentration sufficient to prevent pre-ignition of the methanol prior to injection of the diesel fuel, and to reduce NOx formation. At low engine speeds and loads, the engine may run on diesel fuel alone.

摘要： A hydraulic machine includes a valve plate, with first and second fluid ports in a surface thereof. A cylinder barrel is rotatably coupled to the valve plate. A plurality of cylinders is formed in the cylinder barrel, such that, as the barrel rotates, each cylinder is coupled to the first and second fluid ports, sequentially. First and second pressure relief ports are formed in the surface of the valve plate between the first and second fluid ports at top- and bottom-dead-center, respectively. A cross-port bore is formed in the valve plate, placing the first and second pressure relief ports in fluid communication with each other. As each cylinder rotates to top-dead-center, an opposite cylinder rotates to bottom-dead-center. The respective cylinders are coupled to the first and second pressure relief ports, such that differential pressure in the cylinders is equalized.
