060620000 | Fluid motor means is expansible chamber type with movable parts of motor and engine being interconnected | 6 |
20090301086 | Selective Compound Engine - The fuel efficiency of an internal combustion reciprocating piston engine may be increased through selective secondary expansion of exhaust gas in the engine cylinders in order to recover exhaust gas energy which is otherwise wasted by cylinder blow-down at the end of the power stroke. Exhaust valve cam switching, intake valve deactivation, multiple exhaust valves, a specialized exhaust manifold arrangement and an exhaust gas diverter valve can be configured to enable a reciprocating engine to selectively operate in efficient eight stroke cycle compound mode when moderate engine power is demanded, then revert to conventional four stroke cycle non-compound mode operation when high engine power is demanded, without stopping the engine. For a road vehicle application, the benefit is substantially reduced highway cruising fuel consumption, while incurring minimal impact on engine weight, minimal impact on engine manufacturing cost, and no adverse impact on vehicle acceleration performance, hill climbing performance or trailer towing performance. | 12-10-2009 |
20140352303 | WASTE HEAT RECOVERY SYSTEM WITH INTEGRATED HYDROCARBON ADSORBER, AND METHOD THEREOF - A waste heat recovery system with an integrated hydrocarbon adsorber for a vehicle having an internal combustion engine that generates exhaust gas containing hydrocarbons, and a catalytic converter, includes an exhaust gas conduit, an exhaust gas heat exchanger, a heat exchanger bypass valve, a coolant circuit with a coolant bypass and a coolant bypass valve, and a controller. The exhaust gas heat exchanger includes at least one channel through which the exhaust gas is flowable, the channel having an interior surface coated with a hydrocarbon adsorbing material configured to adsorb hydrocarbons. The heat exchanger and coolant bypass valves are configured to selectively direct at least a portion of the exhaust gas and the coolant, respectively, to the exhaust gas heat exchanger or to bypass it. They are controlled by the controller such that the hydrocarbons in the exhaust gas are selectively adsorbable by and desorbable from the coating. | 12-04-2014 |
20160010588 | System and Method for Recovering Waste Heat | 01-14-2016 |
20160053678 | WASTE HEAT RECOVERY SYSTEM - A method and apparatus for controlling the mass flow rate of a positive displacement expander comprises pumping a working fluid to a heat exchanger to convert the fluid into a working vapor. At least a portion of the working vapor is stored in an accumulator connected to the heat exchanger. At least a portion of the working vapor stored in the accumulator is selectively released into a positive displacement expander via a pulse width modulated valve to increase the efficiency of the expander. | 02-25-2016 |
060623000 | Fluid motor is rotary type | 2 |
20080223040 | Supercharged Internal Combustion Engine with an Expander Unit in a Heat Recovery Circuit - A supercharged internal combustion engine of a motor vehicle has a cooling circuit, in which a working medium is recycled, which is conveyed at least partially in a vaporous or gaseous physical state. At least one expander unit is provided which is operatively connected with an output shaft of the internal combustion engine via a power train. Via a conversion of energy contained in the at least partially vaporous or gaseous working medium in the expander unit, an output shaft of the expander unit is moveable. The expander unit is embodied as a two-cycle reciprocating engine, which is operatively connected directly or indirectly via the power train with the output shaft of the internal combustion engine. | 09-18-2008 |
20100313562 | PROCESS FOR RECOVERING POWER FROM FCC PRODUCT - Disclosed is a process for recovery power from an FCC product. Gaseous hydrocarbon product from an FCC reactor is heat exchanged with a heat exchange media which is delivered to an expander to generate power. Cycle oil from product fractionation may be added to the gaseous FCC product to wash away coke precursors. | 12-16-2010 |
