摘要： A blow-by gas device of a supercharger-equipped engine includes a blow-by gas passage that introduces blow-by gas into an intake passage via a positive crankcase ventilation (PCV) valve. A supercharger has a supercharger rotor provided integrally with a rotation shaft rotatably supported on a bearing part. A space communicating with the bearing part is connected to a communication passage. The communication passage guides the blow-by gas into the space.

摘要： In a control device for an internal combustion engine having a turbocharger with a variable turbo flow rate, and an intake valve provided with a variable valve mechanism, mirror cycle operation is performed. The control device includes a device which calculates an intake air quantity per unit time and an intake air quantity per cycle on the basis of torque required to the internal combustion engine. The turbocharger is controlled so that, with the calculated intake air quantity per unit time, supercharging pressure is further increased in a range in which the ratio of exhaust pressure to supercharging pressure is equal to or less than a predetermined value. A further device, which controls the variable valve mechanism on the basis of the supercharging pressure and the calculated intake air quantity per cycle.

摘要： A combustor for a gas turbine engine is disclosed which is able to operate with high combustion efficiency, and low nitrous oxide emissions during gas turbine operations. The combustor consists of a can-type configuration which combusts fuel premixed with air and delivers the hot gases to a turbine. Fuel is premixed with air and is delivered to the combustor with a high degree of swirl motion. This swirling mixture of reactants is conveyed through a flowpath that expands; the mixture reacts, and establishes a central recirculation zone. An imperforate trapped vortex cavity is disposed proximal to the swirler apparatus which provides for a second reaction zone. Fresh fuel/air reactants are exchanged with burned products in the trapped vortex and a pilot flame is established in the trapped cavity. The imperforate trapped cavity is not supplied with either fuel or air, but is cooled on a backside of the cavity with a flow of cooling air. The cooling air is then conveyed to the combustion chamber so as to not interfere with the critical flame holding flow features of the combustor.

摘要： An engine, having an intake passage, a throttle valve arranged in the intake passage, and a fuel injector arranged in the intake passage for injecting fuel into the intake passage, comprises an air-flow control valve arranged in the intake passage between the fuel injector and the throttle valve. The air-flow control valve is controlled to close during the engine starting operation, and to open after the engine starting operation completes. The air-flow control valve has a valve element having an axis about which the element is rotatable when the valve is opened or closed. The rotational direction of the valve element is selected so that air flowing through the valve is guided by the valve toward the fuel injector when the air-flow control valve is controlled to an intermediate open position which is between the closed position and the full open position.

摘要： An intake manifold for use with a combustion engine is disclosed. The intake manifold comprises a dimensionally stable induction pipe body having at least one first flow-through opening and at least one first adjusting element arranged in the first flow-through opening to vary the available cross-sectional area of the passage. This adjusting element takes the form of a throttle valve, which is rotatably supported in the induction pipe body and which is capable of being forced to engage sealingly with the boundary wall of the first flow-through opening. In the area of the throttle valve, the induction pipe body has at least one second flow-through opening, which is allocated as a by-pass so as to be adjacent to the first flow-through opening, said second flow-through opening being capable of being sealed by at least one second adjusting element, which is comprised of a one-way valve that is only able to be forced into an open position in the direction of the attached combustion engine.
