摘要： An internal combustion engine with a dual turbocharger system includes an engine, a first turbocharger and a second turbocharger arranged in parallel with each other, an intake switching valve located downstream of a compressor of the second turbocharger, and an exhaust switching valve located downstream of a turbine of the second turbocharger. At large intake air quantities, both turbochargers are operated, while at small to medium intake air quantities only the first turbocharger is operated. At "one-turbocharger-operation", when the engine load is low, the intake switching valve is opened, while the exhaust switching valve is maintained closed. Thus, at small to medium intake air quantities and low engine loads, the intake flow can be introduced through both the compressor of the first turbocharger and the compressor of the second turbocharger. As a result, flow resistance is decreased and acceleration response from low engine loads is improved.

摘要： An internal combustion engine with a dual turbocharger system which includes an engine, a first and a second turbocharger arranged in parallel with each other, an intake switching valve located downstream of a compressor of the second turbocharger, an exhaust switching valve located downstream of a turbine of the second turbocharger. The engine operation is changed between a "one-turbocharger-operation" wherein only the first turbocharger is operated and a "two-turbocharger-operation" wherein both the first turbocharger and the second turbocharger are operated. Change from the "one-turbocharger-operation" to the "two-turbocharger-operation" is performed on the basis of an intake air quantity, and change from the "two-turbocharger-operation" to the "one-turbocharger-operation" is performed on the basis of an engine speed. This type of change suppresses a torque shock at shift changing during acceleration and improves the drive feeling.

摘要： An internal combustion engine with a dual turbocharger system includes an air bypass conduit connecting a downstream portion of a first turbocharger compressor with an upstream portion of a second turbocharger compressor so that the length of the air bypass conduit is relatively long. When a throttle is rapidly closed, an air bypass valve installed in the air bypass conduit is opened and the compressed air downstream of the throttle valve is returned to the upstream of the turbocharger compressor to suppress occurrence of a surging at the turbocharger compressor. Since the air bypass conduit is relatively long, the compressed and circulated air is effectively cooled when flowing through the air bypass conduit and melting of an impeller of the turbocharger compressor is prevented.

摘要： An internal combustion engine with a dual turbocharger system which includes an engine, a first and a second turbocharger arranged in parallel with each other, an intake switching valve located downstream of a compressor of the second turbocharger, an exhaust switching valve located downstream of a turbine of the second turbocharger, and an exhaust bypass valve installed an exhaust bypass conduit bypassing the exhaust switching valve. The exhaust bypass valve is opened on the basis of a charging pressure at low engine speeds and is opened on the basis of an intake air quantity at high engine speeds. As a result of controlling the exhaust bypass valve in this fashion, a smooth transition from a "one-turbocharger-operation" to a "two-turbocharger-operation" can be obtained throughout the entire range of engine speeds.

摘要： An internal combustion engine with a dual turbocharger system includes a first turbocharger and a second turbocharger arranged in parallel with each other. An exhaust switching valve is installed in an exhaust conduit downstream of a turbine of the second turbocharger and is actuated by a single diaphragm actuator. An exhaust bypass conduit is provided so as to bypass the exhaust switching valve, and an exhaust bypass valve is installed in the exhaust bypass conduit. Before the operation is changed from "one-turbocharger-operation" to "two-turbocharger-operation", the exhaust bypass valve is opened before the exhaust switching valve is opened, to suppress a shock which may occur at the transition from the "one-turbocharger-operation" to "two-turbocharger-operation".

摘要： An evaporated fuel discharge suppressing apparatus includes a main purge conduit and a bypass purge conduit. The main purge conduit connects a canister and an intake conduit of an engine downstream of a throttle valve, and a purge control solenoid valve is installed in the main purge conduit. The bypass purge conduit bypasses the purge control solenoid valve. Even if the purge control solenoid valve sticks in a closed position, evaporated fuel adsorbed by the canister can flow into the intake conduit of the engine through the bypass purge conduit so that the evaporated fuel in the canister is not discharged into the atmosphere.

摘要： An internal combustion engine with a dual turbocharger system includes a first turbocharger operated through an entire intake air quantity, a second turbocharger operated only at large intake air quantities, an exhaust bypass conduit bypassing a turbine of the second turbocharger, an exhaust bypass valve installed in the exhaust bypass conduit, and exhaust bypass valve opening control means for controlling at least one of a time to begin opening and a speed of opening the exhaust bypass valve. The exhaust bypass valve is opened before the turbocharger operation is switched from a "one-turbocharger-operation" to a "two-turbocharger-operation" so that the second turbocharger is run-up and a smooth transition can be obtained. The exhaust bypass valve begins to open at a lower charging pressure when a transmission gear position is low than when the gear position is high, a period of time for running-up the second turbocharger is lengthened so that the second turbocharger is sufficiently run-up and a torque shock at the transition form "one-turbocharger-operation" to "two-turbocharger-operation" is minimized.

摘要： An EGR apparatus includes a EGR passage for allowing part of exhaust gas discharged from a combustion chamber of an engine to an exhaust passage to flow in an intake passage and recirculate back to the combustion chamber, and an EGR valve provided in the EGR passage to regulate an EGR passage in this passage. The EGR valve includes a valve seat, a valve element to be seatable on the valve seat, and a step motor for driving the valve element to open and close. An electronic control device controls the EGR valve to repeat opening and closing of the valve element between a closing position and a small opening position in order to remove foreign matters adhered to the valve seat or valve element during deceleration fuel cutoff of the engine.
