摘要： A conventional gasoline engine is retrofitted and calibrated to operate as a bi-fuel engine using Hydrogen as the second fuel. When operated with Hydrogen, which typically leads to a reduction of engine output power, the engine is preferably operated in a charged mode and in a lean mode with the engine throttle kept in a wide-open position during charged and lean mode operation resulting in a more efficient engine with a reduction of engine output power loss.

摘要： An exhaust gas-conducting section of an exhaust turbocharger comprises a duct with a through-flow opening which can be fully or at least partially blocked or released by a closure element of a control device. The closure element is designed as a poppet valve. The closure element can be moved by an actuator can be disposed in a wall of the exhaust gas-conducting section. The closure element has a closure body with an annular section surface on its bottom surface which faces the through-flow opening. The section surface corresponds to an element seat formed in the wall. Its top surface faces away from the bottom surface and is designed in a profiled manner in order to produce a top surface at least partially corresponding to another element seat and/or to achieve flow-optimized circulation.

摘要： A valve assembly for controlling exhaust gas flow to a turbine housing interior of a dual volute turbocharger includes a first valve member, a valve shaft, and a second valve member. The first valve member is disposed about and extends along an axis between a first end and a second end and is movable between a first, a second, and a third position for controlling exhaust gas flow to the turbine housing interior. The first valve member defines a valve interior between the first and second ends. The valve shaft is partially disposed in the valve interior and is coupled to the first end of the first valve member. The second valve member has a base coupled to and disposed about the valve shaft and a projection extending from the base and about the shaft into the valve interior. The second valve member is movable between closed and open positions.

摘要： The present invention is related to the housing (60) of an exhaust turbine (32) of a turbocharger comprising a first volute (61) and a second volute (62), each of the volutes (61,62) ending in respective first and second guide tongues (64,66). The gap between the first guide tongue (64) and turbine wheel is smaller than the gap between the second guide tongue (66) and turbine wheel. This tongue asymmetry allows for control of the pulse amplitude emitted when a blade of the turbine wheel passes by each respective tongue. Moreover, by increasing the wheel-to-tongue distance of only the second guide tongue (66) durability requirements can be met.

摘要： This invention relates to a turbocharger (210). More specifically, the invention relates to an axial-entry type turbocharger, where the exhaust gases are directed to meet the turbine wheel at least front-on, having a variable volume for controlling pressure, allowing for a substantially uniform pressure and uniform velocity to act simultaneously on and around the turbine wheel, while enabling the volume of the turbocharger to be adjusted under predetermined set pressure conditions. The turbocharge includes: a turbine housing defining a substantially axial primary flow duct, a primary turbine wheel (216) mounted along such primary flow duct (214), and a diverter (218) for diverting flow passing thereover into a primary annular flow path directed to impinge the primary turbine wheel (216). The turbine housing of the turbocharger defines a secondary flow duct (222) for directing some flow to: (i) impinge the primary turbine wheel (216); and/or (ii) bypass the primary turbine wheel (216). A secondary flow duct gate (223) controls flow through the secondary flow duct (222) and is movable between a closed position, wherein under low pressure conditions flow is restricted from flowing through the secondary flow duct (222), and an open position, wherein flow though the secondary flow duct (222) is enabled such that operative flow passes through both the primary and the secondary flow ducts (216, 222) under high pressure conditions. The turbocharger further includes at least one compressor coupled to the primary turbine wheel (216) via a primary transmission thereby to transmit drive from the primary turbine wheel (216) to the compressor.

摘要： An engine controller calculates a pulsation correction value based on actuation states of an air bypass valve (ABV) and a wastegate valve (WGV) that change the shape of intake and exhaust flow passages of an exhaust turbocharger. The pulsation correction value is used to compensate for an output error of an airflow meter caused by intake pulsation. The engine controller also calculates a fuel injection amount of an injector, based on an output of the airflow meter that has been corrected based on the pulsation correction value.

摘要： A system including a cooling fan, an actuator with an actuator temperature sensor, and a controller is disclosed. The controller may be configured to receive temperature data from the actuator temperature sensor. The temperature data may include information relating to an actuator temperature of the actuator. The controller may be configured to compare the actuator temperature with a temperature threshold associated with the actuator, and control the cooling fan to adjust the actuator temperature based on determining that the actuator temperature satisfies the temperature threshold.

摘要： A method for controlling and engine system with a plurality of turbochargers. At least one of the plurality of turbochargers has a turbine valve, a compressor valve, and actuators operable to change the position of the turbine valve. The method comprises controlling the actuator based on the presence of a transient event or a steady state event. During a transient event an engine control module can control the actuators to change the turbine valve to opened and closed positions and the turbine valve to a closed position based on the comparison between a corrected mass flow per turbocharger to a mass flow threshold.

摘要： The invention relates to a method of controlling transient behaviour of an internal combustion engine (10) being provided with a turbocharger (110) and a variable inlet guide vanes assembly (130) arranged upstream a compressor (120) of the turbocharger (110). The method comprises determining a current operational condition indicative of transient behaviour, and, if said transient behaviour requires compressor acceleration: determining a desired operational condition of the compressor (120), and controlling the position of the variable inlet guide vanes assembly (130) based on the desired operational condition of the compressor (120).
