20100095914 | EXTERNAL COMPRESSION TWO-STROKE INTERNAL COMBUSTION ENGINE - A system and method is described for an internal combustion engine. The system comprises a compressor configured increase a pressure and temperature of a gas to produce a compressed gas and to maintain a continuous pressure and temperature of the compressed gas at more than four times ambient pressure and greater than a combustion temperature of a fuel and an internal combustion engine. The internal combustion engine includes a cylinder configured to receive the compressed gas from the compressor at the increased pressure and temperature, a piston disposed in the cylinder, and an intake valve disposed between the compressor and the cylinder, the intake valve configured to open based on a position of the piston for admitting the compressed gas into the cylinder. The system further includes a fuel source configured to provide the fuel to the cylinder. | 04-22-2010 |
20100095915 | EXTERNAL COMPRESSION TWO-STROKE INTERNAL COMBUSTION ENGINE WITH BURNER MANIFOLD - A system and method is described for an internal combustion engine system. The system comprises a compressor configured to produce compressed, heated gas for the internal combustion engine and a burner manifold. The burner manifold also receives fuel for mixing with the compressed, heated gas. A resultant combustion gas may be used to provide energy for driving the compressor. In some embodiments, combustion gas from the burner manifold may drive a turbine which in turn may drive the compressor. The internal combustion engine also receives compressed, heated gas from the compressor for combustion in a two cycle mode. The internal combustion engine may receive compressed gas via the burner manifold. | 04-22-2010 |
20100122676 | INTERNAL-COMBUSTION ENGINE WITH REDUCED POLLUTANTS - A method and apparatus for pumping an intake charge into an engine is disclosed herein. The fuel-powered engine utilizes a barrier between an intake manifold and a crankcase of the engine to substantially protect the intake charge from contamination by engine crankcase oil, while using the natural pumping action of a reciprocating engine piston to pump the intake charge into the combustion chamber. | 05-20-2010 |
20120174881 | FULL EXPANSION INTERNAL COMBUSTION ENGINE - A two-stroke, uniflow, full expansion internal combustion (IC) engine having cylinders that include a cylinder wall and a cylinder head having an exhaust port with exhaust valve, a fuel injector, and a spark means in the cylinder head, and a piston mounted in the cylinder for reciprocal stroke movements of compression and power between a top dead center (TDC) position and a bottom dead center (BDC) position. The cylinder has a swirl inlet port passing through the cylinder wall at the bottom of the cylinder that is covered and uncovered in response to the reciprocal movement of the piston. The cylinder is operated through a cycle where the exhaust port is held in an open position for a portion of the compression stroke movement of the piston, to provide a delay in the onset of the compression phase of the cylinder cycle. | 07-12-2012 |
20130319354 | Two-Stroke Engine And Related Methods - A two-stroke engine includes a crankshaft that is rotatable about an axis, and an engine block that includes a combustion cylinder and a compression cylinder. A first piston is slidably disposed within the combustion cylinder and is operatively coupled to the crankshaft for reciprocating movement within the combustion cylinder through a power stroke during each rotation of the crankshaft about the axis. A second piston is slidably disposed within the compression cylinder and is operatively coupled to the crankshaft for reciprocating movement within the compression cylinder such that fresh air is received and compressed in the compression cylinder during each rotation of the crankshaft about the axis. A conduit provides fluid communication between the combustion cylinder and the compression cylinder, and a fuel injector is in communication with the combustion cylinder for admitting fuel into the combustion cylinder. | 12-05-2013 |
20140060466 | FULL EXPANSION INTERNAL COMBUSTION ENGINE - A two-stroke, uniflow, full expansion internal combustion (IC) engine including a plurality of cylinders, including a cylinder wall and a cylinder head having an exhaust port, an exhaust valve disposed in the exhaust port, a fuel injector and a spark means disposed through the cylinder head, a piston mounted in the cylinder for reciprocal movement between a top dead center (TDC) position and a bottom dead center (BDC) position, and through a compression stroke and a power stroke, and a swirl inlet port passing through the cylinder wall at the bottom of the cylinder, wherein the swirl inlet port is covered and uncovered in response to the reciprocal movement of the piston. The exhaust port is held in an open position for a portion of the compression stroke movement of the piston, to provide a delay in the onset of the compression phase of the cylinder cycle. | 03-06-2014 |
20140261261 | PORTING SYSTEM FOR A TURBO-CHARGED LOOP SCAVENGED TWO-STROKE ENGINE - A porting system for a turbo-charged loop scavenged two-stroke engine includes a cylinder including a cylinder wall and a cylinder head. At least one inlet port is provided in the cylinder wall. The at least one inlet port is arranged a first distance from the cylinder head and fluidically connected to a compressor portion of a turbo-charger. A first exhaust port is provided in the cylinder wall. The first exhaust port is arranged a second distance from the cylinder head and is fluidically connected to a turbine portion of the turbo-charger through first exhaust passage. A second exhaust port is provided in the cylinder wall. The second exhaust port is arranged a third distance from the cylinder head that is greater than the second distance and the second exhaust passage is fluidically connected to a second exhaust passage bypassing the turbine portion. | 09-18-2014 |
