20120304967 | Ultra Efficient Engine - An engine comprises a combustion chamber, an expansion cylinder with a piston adapted for reciprocating motion in the expansion cylinder via combustion products combusted in the combustion chamber, and a transmission associated with the expansion cylinder. The transmission has a guide frame with a first drive wheel rotatably mounted at one end of the guide frame and a second drive wheel rotatably mounted at an opposite longitudinal end of the guide frame. Each of the drive wheels is driven by an inextensible continuous loop. The guide frame has a crank head adapted to reciprocatingly translate along the guide frame. The crank head has a drive connection pivotally connecting the crank head to the loop. The crank head is operatively connected to the piston such that reciprocating motion of the piston results in corresponding reciprocating motion of the crank head, movement of the loop, and corresponding rotation of the drive wheels. | 12-06-2012 |

20120125289 | SPARK IGNITION TYPE INTERNAL COMBUSTION ENGINE - An internal combustion engine can form, in a combustion chamber, a fuel-air mixture region located on the first intake port side and containing mainly a fuel-air mixture, and a burned gas region located on the second intake port side and containing burned gas. When the region and a burned gas region are formed, the internal combustion engine determined injection rates of a first fuel injection valve and a second fuel injection valve so that fuel is injected from the first fuel injection valve and second fuel injection valve respectively, depending on an EGR rate. The injection rates are determined such that the injection rate of the first fuel injection valve is increased in accordance with the rise of the EGR rate. | 05-24-2012 |
20140116384 | METHOD FOR INJECTING FUEL INTO A COMBUSTION CHAMBER OF A GAS TURBINE, AND INJECTION SYSTEM FOR IMPLEMENTING SAME - An air/fuel mixer system of a combustion chamber of a gas turbine includes at least one compressed air intake swirler, the swirler having a central axis of symmetry, and a fuel injector including an injection head having an axis of symmetry. Each injector is mounted in the corresponding swirler with aid of a guide mechanism, so that the axis of symmetry of the injection head is off-center with respect to the central axis of symmetry of the swirler. The system can reduce, or even eliminate, combustion instabilities, by injecting the fuel along a particular axis which is off-center relative to the axis of the air/fuel mixer system, inducing a flow of fuel which is no longer perfectly axially symmetrical. | 05-01-2014 |

20080210198 | Internal combustion engine and fuel injection method in internal combustion engine - An air-fuel ratio of an air-fuel mixture produced by fuel injected from a first injector into an intake port (or into a combustion chamber) is set in a range of 28 to 38. Therefore, when the temperature and pressure rise with a first combustion started by spark-ignition around a spark plug to the fuel injected from a second injector into the combustion chamber, the timing of starting a second compressive hypergolic ignition is optimized to provide a stable combustion state free of knocking and misfire. | 09-04-2008 |

20120152204 | FUEL MANAGEMENT SYSTEM FOR VARIABLE ETHANOL OCTANE ENHANCEMENT OF GASOLINE ENGINES - Fuel management system for efficient operation of a spark ignition gasoline engine. Injectors inject an anti-knock agent such as ethanol directly into a cylinder of the engine. A fuel management microprocessor system controls injection of the anti-knock agent so as to control knock and minimize that amount of the anti-knock agent that is used in a drive cycle. It is preferred that the anti-knock agent is ethanol. The use of ethanol can be further minimized by injection in a non-uniform manner within a cylinder.

20140026853 | Low Temperature Dual Fuel Combustion Utilizing Diesel and Methanol Fuels - To reduce emissions at higher engine loads and speeds, methanol fuel is port-injected with charge-air into a diesel engine, and diesel fuel is then direct-injected to initiate combustion. The charge-air has a reduced oxygen concentration sufficient to prevent pre-ignition of the methanol prior to injection of the diesel fuel, and to reduce NOx formation. At low engine speeds and loads, the engine may run on diesel fuel alone. | 01-30-2014 |

20160097316 | METHOD FOR OPERATING A COMPRESSION IGNITION ENGINE - A method for operating a compression ignition engine includes forming a combustible mixture by mixing generally homogeneously a first fuel and air and introducing this mixture into the at least one cylinder, compressing the combustible mixture with the piston in a compression stroke, injecting a second fuel to the combustible mixture at an injection-time of the second fuel during the compression stroke but before start of combustion, and continuing the compression stroke until combustion starts at those locations in the at least one cylinder where concentration of the second fuel is highest and/or the temperature of the mixture is the highest. Emission of the cylinder and/or mechanical stress of the cylinder caused by the combustion are monitored, and if emissions and/or mechanical stress are above respective predetermined thresholds, individually for the cylinder, the amount and/or the timing of the second fuel injected, and/or temperature of the cylinder charge is changed. | 04-07-2016 |
