    摘要: A system and method are provided for avoiding transient compressor surge in a turbocharged internal combustion engine. The system includes a control circuit responsive to at least one engine operating parameter to determine a minimum fueling limit that is generally higher under certain engine operating conditions than the default engine fueling value. Under such conditions, the minimum fueling limit is used to establish a lower limit of fuel supplied to the engine in order to avoid turbocharger transient compresser surge conditions. In one embodiment, the at least one engine operating parameter includes intake manifold air pressure, and in an alternative embodiment, the at least one engine operating parameter further includes intake manifold air temperature. In either case, the at least one engine operating parameter also preferably includes engine speed.

    摘要: A thrust bearing for a turbocharger includes a main body portion which defines a central bore for receipt of a thrust collar, an oil reservoir in the shape of a blind, oblong slot disposed in the main body portion and an oil passageway connecting the oil reservoir with the central bore. As oil is drained from the turbocharger by a siphoning action as the engine oil level drops, oil which is stored in the oil reservoir will remain and after the engine has completely stopped this stored oil is available to drain into the interface between the thrust collar and central bore of the thrust bearing in order to provide lubricating oil to this interface upon restart of the engine. Oil is also provided by the reservoir to the turbine and compressor journal bearings where it is held in small clearances on the inner and outer surfaces of the journal bearings.

    摘要: An internal combustion engine has a turbocharger inlet flange mounted to the outlet flange of the exhaust manifold of the engine. The exhaust gas flow out of the manifold is through two ports having a centrally located guide wall directing flow from the manifold out the flange into the turbocharger inlet. The two ports are trapezoidal in shape with a short common dividing wall which, for each port, blends at a short radius into two diverging straight walls, one at each end of the common wall, and which blend from their ends into the outer wall of the port, resulting in trapezoidal port shape. The inlet flange of the turbocharger casing has ports matching and in registry with the two ports of the exhaust manifold flange.

    摘要: The present invention relates to an internal combustion engine and more particularly to an internal combustion engine which includes a turbocharger system having at least one smaller exhaust gas turbocharger and at least one larger exhaust gas turbocharger, as well as means for controlling the exhaust gas and intake air flow to the respective turbochargers. The turbochargers and control means are interconnected to provide pressurized intake air throughout the entire operating range of the internal combustion engine, while effectively bypassing the smaller exhaust gas turbocharger during operating conditions which produce high exhaust gas volumes. The operating characteristics of this turbocharger system are matched with the operating range of an internal combustion engine to provide improved performance, efficiency, transient response and reliability, while reducing maintenance and undesirable emissions.

    摘要: A closed crankcase ventilation system for a turbocharger internal combustion engine which uses differential pressure between the turbo compressor inlet and the crankcase to force blow-by gases through a separation device. The zone of low pressure of the turbo compressor inlet is located at the innermost diameter of the compressor inlet shroud. The difference between the pressure in the compressor inlet and the crankcase creates a vacuum which pulls gas from the crankcase into the ventilation system. The ventilation system includes a high restriction separator for removing oil from the blow-by gases. A control valve bypasses the separation device when insufficient pressure differential exists to drive the separator. Additionally, a system for ventilating crankcase gases from a crankcase of the engine includes a first flow passage communicating between the crankcase and a turbocharger of the engine, an high restriction separator positioned in the flow passage for separating air contaminant mixtures from crankcase gases, a first connection for connecting a first end of the flow passage to the crankcase, a second connection for connecting a second end of the flow passage to a predetermined point of the turbocharger, a second flow passage communicating between the first flow passage and an intake manifold of the engine, and a bypass flow passage for bypassing the separator. In this case, the crankcase gases are directed through the separator during heavy load, light load and idle operating conditions when sufficient vacuum exists to draw the crankcase gases through the coalescing filter and through the bypass flow passage when a sufficient vacuum is not present.
