| 060712000 | Engine apparatus or system actuatable selectively or simultaneously by internal combustion of fuel and by expansion of motive fluid | 10 |
| 20090145129 | SPLIT-CYCLE AIRCRAFT ENGINE - A split-cycle aircraft engine includes a crankshaft rotatable about a crankshaft axis. A power piston is slidably received within a power cylinder and is operatively connected to the crankshaft such that the power piston reciprocates through an expansion stroke and an exhaust stroke during a single rotation of the crankshaft. A compression piston is slidably received within a compression cylinder and is operatively connected to the crankshaft such that the compression piston reciprocates through an intake stroke and a compression stroke during a single rotation of the crankshaft. A gas crossover passage operatively interconnects the compression cylinder and the power cylinder. An air reservoir is operatively connected to the gas crossover passage by a reservoir passage. The air reservoir is selectively operable to receive and deliver compressed air. The engine is mounted to an aircraft and the air reservoir is disposed within the aircraft. | 06-11-2009 |
| 20090288419 | Tractor trailer power system - The present invention relates to a tractor trailer power system for powering a hydraulic liftgate and other components in the trailer so the tractor engine does not have to run to maintain the battery charge of the trailer batteries. | 11-26-2009 |
| 20090293480 | High Efficiency Multicycle Internal Combustion Engine With Waste Heat Recovery - A high efficiency combined cycle internal combustion and steam engine includes a cylinder having a piston mounted for reciprocation therein with an internal combustion chamber outward of the piston, a fixed cylinder cap sealingly and slidably mounted within the piston and a steam expansion and recompression chamber inside the piston adjacent the cylinder cap. The cylinder cap can be unheated or heated externally to reduce condensation of steam entering the steam chamber from a steam generator fired by waste combustion heat. After a steam exhaust valve closes at the top center position, residual steam is recompressed during an inward stroke of the piston up to admission pressure prior to admitting the next charge of steam. A wrist pin that is connected to an inner part of the skirt of the piston and located inwardly of the cylinder cap is coupled to a connecting rod that is secured at its inner end to a crankshaft. One valve or a pair of retractable steam inlet valves connected in series within the cylinder cap inside the piston act in cooperation with steam recompression and a variable clearance volume to achieve an effective zero steam chamber clearance and a gain in mean Rankine cycle temperature to maximize efficiency. The amount of steam admitted each outward stroke is continuously regulated to reduce fuel consumption. Engine coolant can be evaporated in an engine cooling jacket to form steam that is superheated in a combustion exhaust manifold. | 12-03-2009 |
| 20100101228 | Drive train comprising an expander driven by fluid or steam - The invention is characterised in that the expander is integrated into the secondary side of the transmission by means of one or more of the following features: the expander has a housing which substantially completely surrounds the expander; the expander is equipped with a drive shaft which projects out of the housing and has a coupling element that is fixed to the drive shaft and that produces a drive connection. The housing of the expander is mounted on the secondary side on the exterior of a transmission housing that surrounds the transmission, or is mounted from the exterior and partially inserted into the transmission housing, in such a way that the coupling element of the drive shaft projects into the transmission housing, producing a direct or indirect drive connection to the transmission output; the transmission has a heat exchanger, which is used to cool transmission oil for lubricating the transmission and/or actuating clutches or brakes inside the transmission, the working medium of the expander being conducted through the heat exchanger in such a way that heat is dissipated from the working medium to partially or completely condense the latter or that heat in the heat exchanger is transferred to the working medium of the expander to heat the latter. | 04-29-2010 |
| 20110247337 | HYBRID DRIVE SYSTEM - The invention relates to a hybrid drive system comprising an internal combustion engine ( | 10-13-2011 |
| 20120117971 | FULL STEAM-DRIVEN INTAERNAL COMBUSTION ENGINE - A full steam-driven internal combustion engine includes a mechanical power system, a combustion system and an air supply system. The mechanical power system includes a turbine and a turbine shaft. The combustion system includes a left main cylinder and a left auxiliary cylinder, and a right main cylinder and a right auxiliary cylinder which are arranged at the left or the right side of the turbine shaft respectively. The air supply system includes a high pressure air bottle connected by a high pressure air pipe and an air compressor. A left high pressure air valve and a right high pressure air valve are arranged on the both sides of the high pressure air bottle respectively and these high pressure air valves are communicated with the left or the right main cylinder by the high pressure air pipe and intake valves respectively. | 05-17-2012 |
| 20120279222 | METHOD AND SYSTEM FOR STORING ENERGY AND GENERATING POWER HEAT IN A SUBSEA ENVIRONMENT - Systems and methods are disclosed for storing energy and generating power and/or heat within a subsea environment. The systems and methods utilize stored compressed air within an air storage chamber to drive an engine/generator system in order to generate power. The engine may or may not utilize combustion. Alternatively, the systems and methods utilize stored compressed air to supply air to a combustor to generate heat. The heat generated can be used for variety of purposes, including to generate steam and to heat heavy oil. | 11-08-2012 |
