摘要： There is provided a method of controlling an engine system. The engine system comprises an internal combustion engine, a supercharging system having at least one supercharger to boost intake air to the internal combustion engine, a turbine, and a motor. The turbine receives an exhaust gas flow from an exhaust system of the internal combustion engine and is capable of at least partly driving the supercharging system. The motor is capable of at least partly driving the supercharging system. The method comprises operating the exhaust system in a first exhaust state and operating the motor in a first motor state when a speed of the internal combustion engine is below a first engine speed, operating the exhaust system in the first exhaust state and operating the motor in a second motor state where power to drive the motor is reduced from that in the first motor state when the speed of the internal combustion engine is between the first engine speed and a second engine speed which greater the said first engine speed, and operating the exhaust system in a second exhaust state where energy transmitted from the internal combustion engine to the turbine is reduced from that in the first exhaust state and operating the motor in the second motor state when the speed of the internal combustion engine is above the second engine speed. Accordingly, the maximum torque can be increased while maintaining the system efficiency over the entire engine speed range.

摘要： An engine includes exhaust manifold integrally formed with a cylinder head. The engine may include an exhaust manifold having at least one single exhaust outlet for exhausting exhaust gas that is exhausted from at least two cylinders that are not adjacent with each other, wherein periods during which exhaust valves are open are not overlapped with each other between the at least two cylinders.The exhaust manifold is integrally formed with the cylinder head such that costs can be reduced. Also, the water jacket is formed between the exhaust passages of the exhaust manifold such that the durability of the turbocharger that is affected by a heat load can be improved.Also, the twin scroll turbocharger is directly connected to the exhaust outlet of the manifold such that the compression ratio of the intake air can be effectively improved. Further, the exhaust passages at which pulsation interference occurs with each other are separately disposed and the exhaust passages at which pulsation interference does not occur are combined together to form a single passage such that the torque is improved at low rpm and the remaining gas is effectively scavenged.

摘要： An exhaust turbocharger is provided which is enhanced in durability and reliability by making the valve body of the waste gate valve to contact uniformly the seat face of the turbine housing at the opening of two exhaust gas bypass passages without affected by the end face of the partition wall partitioning the two bypass passages, thereby preventing generation of vibration and vibration sound (chattering) of the valve body and occurrence of gas leakage due to defective seating of the valve body against the seat face of the turbine housing. The turbocharger has a twin scroll type turbine housing having two exhaust gas entrance channels and two exhaust gas bypass passages for allowing exhaust gas entered the turbine housing to bypass the turbine rotor and being equipped with a waste gate valve for opening/closing the two exhaust gas bypass passages by allowing a plate-like valve body to seat against and depart from a seat face at an outlet end side of the two bypass passages, wherein a depression is formed to a seat-side face of the valve body or to the end face of the partition wall so that the seat-side face of the valve body does not contact the end face of the partition wall at least in the central region of the end face of the partition wall when the valve body seats against the seat face at the outlet end side of the bypass passages.

摘要： A turbocharger for a power system is disclosed. The turbocharger has an impeller wheel, which is rotatable about a central axis and includes a back face at least partially defining a reference plane substantially perpendicular to the central axis. In addition, the turbocharger includes a housing configured to at least partially enclose the impeller wheel. The housing also has at least one volute configured to fluidly communicate fluid with the impeller wheel. The entire length of the at least one volute from a turbocharger inlet is axially inclined relative to the reference plane so the fluid flows in both a radial and axial direction.
