Abstract: A fuel cell power generation system is disclosed which includes a primary fuel cell stack for generating a first quantity of electric power, an auxiliary fuel cell stack for generating a second quantity of electric power, a fuel handling subsystem for feeding a fuel containing hydrogen to the primary fuel cell stack and the auxiliary fuel cell stack, an oxidant handling subsystem including a compressor for feeding an oxidant containing oxygen to the primary fuel cell stack, and a controller electrically connected to the primary fuel cell stack, the auxiliary fuel cell stack, the fuel handling subsystem and the oxidant handling subsystem for controlling operation of the fuel cell power generation system.

Abstract: A variable displacement swash plate type compressor which incorporates a lubrication passage formed in a cylinder block and crankcase, and a spray nozzle disposed at the crankcase end of the lubrication passage. The lubrication passage provides fluid communication between an oil sump and the spray nozzle, and the spray nozzle causes lubricating oil to be efficiently distributed as a fine mist or spray to the crank chamber. The lubrication passage and spray nozzle maximize the flow of refrigerant gas and lubricating oil to the crank chamber under all operating conditions providing cooling and lubrication to the internal moving components within the crankcase.

Abstract: A four-stroke internal combustion engine is disclosed wherein fuel and exhaust vapors are purged from the manifolds and each cylinder when the engine is shut down to minimize emissions on subsequent startup. The engine includes a cylinder, a reciprocating piston within the cylinder, and a cylinder head. An exhaust port with an exhaust valve communicates with the cylinder and an exhaust manifold with an emissions control device. An intake port with an intake valve communicates with the cylinder. Upon engine shutdown, a controller sends signals to a variable valve timing system for opening the exhaust valve when the piston is in upward motion, later closing the exhaust valve when the piston is in upward motion, opening the intake valve when the piston is in downward motion, later closing the intake valve when the piston is in downward motion, and opening the exhaust valve when the piston is in upward motion.

Abstract: A mounting lug 10 for use on a variable capacity swash plate type compressor that is movably disposed on the outer surface of the compressor housing 26. The mounting lug 10 facilitates the mounting of a single swash plate type compressor in a variety of vehicles, thereby eliminating the requirement of producing a different mold to cast a compressor housing 26 for each different vehicle in which the swash plate type compressor will be installed.

Abstract: A variable displacement swash plate type compressor which incorporates a conduit formed in the cylinder block to provide fluid communication between a crank chamber and one or more cylinders to eliminate the need for an orifice tube in fluid communication between a discharge chamber and the crank chamber and to increase the flow of refrigerant gas and lubricating oil to the crank chamber under all operating conditions and to increase the internal fluid pressure in the crank chamber.

Abstract: A throttle body and an air control system that integrates the electronic engine control modules, sensors, actuators, and associated wiring on a throttle body is disclosed. In one version of the invention, there is provided a throttle body including a throttle body wall defining an airflow passage in the throttle body, a movable throttle plate that substantially conforms to the interior dimensions of the air flow passage, an engine control device (such as a sensor or an actuator) attached to the throttle body wall, and engine control electronics mounted to the throttle body wall in spaced apart relationship with the engine control device, the engine control electronics being electrically connected with the engine control device.
