摘要： The invention relates to an engine having prechamber ignition, in particular a gas engine, that comprises a main combustion space in a cylinder of the engine for combusting an air-fuel mixture and a prechamber having an ignition device arranged therein and a fuel injector arranged therein, wherein the prechamber has at least one transfer port that fluidically connects the prechamber to the main combustion space. The engine is characterized in that the fuel injector arranged in the prechamber is the only fuel injector via which fuel can be introduced into the associated main combustion space.

摘要： Methods and systems are provided for reducing wall-wetting and improving mixing of air and fuel within a pre-chamber system of an engine. In one example, a method comprises supplying an air flow to the pre-chamber system via an air injector system while a piston associated with a main chamber is undergoing reciprocating motion. In this way, a rotating or swirling flow of fuel exiting a pre-chamber fuel injector of the pre-chamber system may be induced, which may reduce wall-wetting and improve air and fuel mixing, and when fuel is not being injected to the pre-chamber system the air flow may pressurize the pre-chamber system to reduce an amount of residuals from the main chamber to the pre-chamber system.

摘要： A combustion driven fastener hand tool is disclosed having an extruded front body component including two to three parallel bores. A first bore forms a cylinder for the piston which drives the fastener. A second bore forms a primary combustion chamber in which a fuel and air mixture is ignited and directed into the adjacent piston cylinder. A third bore (or alternately an attached component) forms a pathway for the fuel and air mixture to be directed into the primary combustion chamber. The combustion driven fastener hand tool includes numerous other features affording improvements over the prior art.

摘要： The present invention provides systems, methods and apparatus to overcome limitations of liquid fuel engine combustion. Liquid fuel is mixed with superheated water which vaporizes, mixes with air and ignites within the injector nozzle. The injector nozzles then accelerate the mixture into the engine combustion chamber where unburned fuel vapor mixes and burns. Combustion begins the instant of injection and increases uniformly. Combustion pressure builds progressively. Combustion of fuel vapor is more ideal, and better controlled. As part of the system and apparatus, the present disclosure also includes a low-cost high-speed solenoid valve which produces shorter injection pulses. It also includes a high-speed, high-air-volume solenoid fuel valve. In addition, the present invention and its disclosure create tools to develop and optimize this new method of fuel vapor injection.

摘要： A process for enhancement of combustion control in rotary and reciprocating IC engines for improving fuel efficiency by enabling leaner combustion at higher compression ratios. Embodiments supporting this process employ a fluid of higher heat of vaporization and higher volatility but lower ignitability than the fuel to increase the compression ratio required for self ignition. These have secondary chambers in a cylinder periphery for radical ignition (“RI”) species generation in an earlier cycle for use in a later cycle. These chambers communicate with a main chamber via conduits. Measures regulate the RI species generated and provided to the main chamber. These species then alter the dominant chain-initiation reactions of the main combustion ignition mechanism by lowering the heat and the fuel ratios required for combustion. This improves combustion in radical ignition engines and radical augmented spark and compression ignition engines.

摘要： To provide a 2-stroke cycle internal combustion engine for a vehicle in which less blowoff of a gas mixture occurs in a combustion chamber, fuel consumption is low and high exhaust gas purifying performance is attained. The cylinder of the internal combustion engine is slightly inclined toward the forward side of the vehicle body from its upright position. The high pressure chamber and the communication passages are arranged forwardly toward the vehicle body from the cylinder. Openings of the communicating passages toward the combustion chamber are arranged, from the scavenging port, near the combustion chamber. The intake control valve rotated from the crank chamber near the openings of the communicating passages toward the combustion chamber is arranged near the openings of the communicating passages, and the exhaust pipe and the exhaust expansion chamber communicating with the exhaust gas passage of the internal combustion engine are arranged at a rear part of the vehicle body from the cylinder.

摘要： In the combustion chamber structure of the gas engine the combustion chamber members are formed with the sub-communication holes allowing communication between the main combustion chambers and the pre-combustion chambers and also with throat holes in which throat hole valves are installed. This structure avoids excessively high compressed air pressure in the main combustion chambers during the compression stroke and reduces the compression work to improve performance. The sub-communication holes open at the wall surfaces situated in the main combustion chambers and also at the upper wall surfaces of the pre-combustion chambers. The axes of the ports of the sub-communication holes opening to the main combustion chambers extend toward the center axes of the throat holes. The axes of the ports of the sub-communication holes opening to the pre-combustion chambers extend offset from the center axes of the pre-combustion chambers. Hence, this gas engine can reduce the compression work, lower the maximum pressure of the compressed air at the end of the compression stroke, prevent the gas fuel from remaining in the pre-combustion chambers, and enhance the air utilization factor, improving thermal coefficient.
