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.
摘要翻译：具有双涡轮增压器系统的内燃机包括将第一涡轮增压器压缩机的下游部分与第二涡轮增压器压缩机的上游部分连接的空气旁通管，使得旁通管道的长度相对较长。当节气门快速关闭时，安装在空气旁通管道中的空气旁通阀打开，并且节流阀下游的压缩空气返回到涡轮增压器压缩机的上游，以抑制涡轮增压器压缩机的喘振发生。由于空气旁通管道相对较长，因此当流过空气旁路管道时，被压缩和循环的空气被有效地冷却，并且防止了涡轮增压器压缩机的叶轮的熔化。

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 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： A diesel engine includes an air intake system, an exhaust system, and an exhaust gas recirculation conduit which leads from the exhaust system to the intake system. An exhaust gas recirculation control valve, which includes a first diaphragm chamber, is mounted in the exhaust gas recirculation conduit so as to regulate the flow of exhaust gas through it. The exhaust gas recirculation control valve is controlled by a controlling fluid pressure supplied to its first diaphragm chamber. A fluid pressure control valve receives supply of fluid pressure and produces this controlling fluid pressure for the exhaust gas recirculation control valve, according to the amount of displacement of a movable member which moves according to the amount of diesel fuel being supplied to the diesel engine. In a particular embodiment, a throttle valve is fitted to the intake system upstream of the point where the exhaust gas recirculation conduit joins to it, and is moved by a fluid pressure actuated diaphragm device including a second diaphragm chamber which is also supplied with the same controlling fluid pressure as is the first diaphragm chamber. Also, in various constructions, valves or the like for cutting off supply of the controlling fluid pressure to the first and second diaphragm chambers when the temperature of the engine is low, and when the engine revolution speed is high, may be provided. A system may also be provided for, when the engine rotational speed is low, either reducing the value of the controlling fluid pressure, or alternatively for cutting off supply of it to the second diaphragm chamber only.

摘要： Carbon-containing particulates like soot included in an exhaust gas of an internal combustion engine are collected by means of a heat-resistant filter medium. The filter medium dispersedly collects hydrocarbon compounds and the carbon-containing particulates included in the exhaust gas. Even when the exhaust gas has a lower temperature than the combustible temperature of the carbon-containing particulates, such dispersed collection ensures start of a preliminary oxidation reaction of the collected hydrocarbon compounds with oxygen included in the exhaust gas. The collected hydrocarbon compounds and the collected carbon-containing particulates are then subjected to combustion with the exhaust gas having a filter inflow temperature lower than the combustible temperature of the carbon-containing particulates by utilizing the reaction heat and active species produced by the reaction. This technique thus simply but securely regulates and reduces the carbon-containing particulates included in the exhaust gas.

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".

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.
