| Number | Title | Issue Date |
| 7260934 | External combustion engine An organic Rankine engine used to power a vehicle is provided with a quick-start system of pumps, electric heaters or pistons to generate a pressure differential across the motor, prior to the engine reaching operating conditions. ... | 08/28/2007 |
| 7234302 | Housing for a turbocharger A housing for a turbocharger forms a housing jacket (6, 7) which surrounds a rotor space (15) for receiving a turbine rotor (18). The housing jacket consists of sheet metal at least in part. A connection pipe (4′) provides for communica... | 06/26/2007 |
| 6202416 | Dual-cylinder expander engine and combustion method with two expansion strokes per cycle An internal combustion engine is provided with an expansion cylinder and at least one combustion cylinder, preferably two or four combustion cylinders per expansion cylinder. An air-fuel mixture is ignited within the combustion cylinders to drive a combus... | 03/20/2001 |
| 6095100 | Combination internal combustion and steam engine An engine (10) having a series of cylinders (12, 14, 16 and 18) in which pistons (30, 32, 34 and 36) are arranged for reciprocation and which are connected to a crankshaft (38). Two of the cylinders (12 and 18) operate in an Otto cycle, and water is injec... | 08/01/2000 |
| 5199262 | Compound four stroke internal combustion engine with crossover overcharging A normally aspirated compounded, overcharged (supercharged) four stroke internal combustion engine, preferably diesel, which is particularly useful in adiabatic (low heat rejection) versions. An auxiliary expansion piston and compression piston reciprocat... | 04/06/1993 |
| 5072589 | Internal combustion engine having multiple expansion and compression A staged two-stroke internal combustion engine with reciprocating pistons wherein the cycle comprises a first compression of fresh air possibly followed by a cooling, a second compression of air or of mixture or the injection of fuel (Diesel version), a f... | 12/17/1991 |
| 4783966 | Multi-staged internal combustion engine The positive displacement internal combustion engine has multiple stages of compression and expansion. After an initial compression, the working fluid is contained at elevated pressure and temperature. Valve controls on the initial compression can limit t... | 11/15/1988 |
| 4353212 | Closed fluid loop solar thermodynamic system Thermodynamic unit comprised of a pair of vessels which alternately raise and lower pressure in thermodynamic fluid is connected in a closed system to an engine, which utilizes the fluid in its gas phase, with the vessel raising pressure having a gas outl... | 10/12/1982 |
| 4321892 | Multiple-cycle, piston-type internal combustion engine The invention relates to a multiple-cycle internal combustion engine having as a unit of two 4-cycle cylinders operating 180° apart and one 2-cycle cylinder firing 90° after the 4-cycle cylinders fire. The 4-cycle exhaust is admitted to the intake port ... | 03/30/1982 |
| 4086882 | Compound combustion engines and methods of compounding same This invention relates to improving the internal combustion and internal use of fuel in engines, and more particularly to engines which are compounded in order to effect extension of the expansion event of the four-event work cycle of such engines which a... | 05/02/1978 |
