摘要： An engine controller, for an internal combustion engine, is configured to:
control at least one actuator to provide an air-fuel mixture with a lambda value higher than 3 to a main combustion chamber via at least one intake valve, wherein the at least one actuator is arranged upstream of at least one intake port or which is arranged in the intake port;
control at least one fuel supply system to provide fuel directly to the main combustion chamber and/or a pre-combustion chamber of a piston-cylinder unit such that at the time of ignition of the air-fuel mixture the lambda value of that air-fuel mixture in the main combustion chamber is lower than the lambda value of the air-fuel mixture provided to the main combustion chamber via the at least one intake valve.-

摘要： The present invention discloses an ammonia-hydrogen fusion fuel diffusion combustion control system based on reactivity regulation, comprising an on-board ammonia-hydrogen fuel supply system, an ammonia-hydrogen fusion fuel diffusion combustion engine and an ECU; the ECU is used to control the intensity of a precombustion chamber jet flame, control the reactivity of a hydrogen-air mixture in a main combustion chamber and control the injection time of an ammonia ejector, thus to form diffusion combustion in the main combustion chamber; the on-board ammonia-hydrogen fuel supply system comprises a low-pressure ammonia fuel supply unit and an on-board hydrogen production unit, and is used to provide prepared low-pressure ammonia fuel and hydrogen for the ammonia-hydrogen fusion fuel diffusion combustion engine; before the formation of the precombustion chamber jet flame, hydrogen regulated by the ECU is firstly injected into the main combustion chamber by a first hydrogen ejector, and then the injection time of the ammonia ejector is controlled by the ECU to be slightly earlier than or synchronous with the formation of the precombustion chamber jet flame, so that ammonia fuel injected into the main combustion chamber is in a state of burning while injecting, thus to form diffusion combustion in the main combustion chamber.

摘要： To effectively suppress strong knock that occurs in the operating region of high load and high rotation in a specific engine having a pre-chamber in a combustion chamber, the engine includes a piston that defines a combustion chamber together with a cylinder block and a cylinder head. The combustion chamber includes a sub-chamber and a main chamber separated from the sub-chamber by a pre-chamber. The specific ratio obtained by dividing a volume of the sub-chamber by a stroke volume of a cylinder is greater than or equal to 0.00005 and less than or equal to 0.00045.

摘要： A dual fuel engine is provided. The dual fuel engine includes an engine cylinder and a piston disposed within the engine cylinder. The dual fuel engine includes a cylinder head coupled to the engine cylinder and a fuel injector coupled to the cylinder head. The fuel injector is adapted to supply a first fuel to the engine cylinder. The dual fuel engine further includes a pre-combustion chamber coupled to the cylinder head at a predetermined distance from the fuel injector. The pre-combustion chamber is in fluid communication with the engine cylinder via at least one conduit and the pre-combustion chamber is adapted to receive a second fuel and an air mixture. The second fuel is different from the first fuel. The dual fuel engine further includes a spark plug structured and arranged within the pre-combustion chamber and the spark plug is adapted to ignite the second fuel within the pre-combustion chamber.

摘要： A combustion driven fastener hand tool is disclosed having a piston driven by combustion within a chamber, the piston affixed to a driver for forcing a fastener. The piston forms a retention chamber having a lower internal pressure (“vacuum”) than that of the surrounding combustion chamber when the piston is disposed in the starting position for operation of the device. The lower internal pressure of the retention chamber (generated from a previous combustion cycle) momentarily holds the piston in place such that combustion behind the piston must first increase sufficiently to overcome holding force of the retention chamber before the piston moves. Requiring build up of combustion chamber pressure before piston motion greatly improves efficiency and power of the device. Use of the vacuum retention chamber is readily tunable with proper sizing of the chamber.

摘要： Auxiliary chamber type internal combustion engine has a main combustion chamber and an auxiliary chamber having an injection port through which the main combustion chamber communicates. The auxiliary chamber has a passage sectional area which is smoothly decreased toward the injection port. Further, the engine has a fuel injector injecting a fuel into the auxiliary chamber; an ignition plug igniting the fuel in the auxiliary chamber; and a swirl generating portion swirling a gas in the auxiliary chamber. The swirl generating portion swirls only the gas flowing into the auxiliary chamber from the main combustion chamber.
