摘要： A bypass venturi assembly for recirculating exhaust gas in an internal combustion engine, and particularly suitable for use in a vehicle, is provided with a housing having an outlet, a combustion air inlet and an exhaust gas inlet. A center piece is positioned within the housing and in communication with the combustion air inlet. The center piece defines a combustion air bypass section therein. An annular venturi nozzle positioned between the housing and the center piece is in communication with the combustion air inlet and defines a combustion air venturi section. The venturi nozzle is in communication with the exhaust gas inlet and defines an exhaust gas venturi section. A combustion air bypass valve is positioned in association with the combustion air bypass section. An exhaust gas valve is positioned in association with the exhaust gas inlet. The venturi nozzle is separate from the housing and allows a nozzle with a particular configuration to be utilized, depending upon the application.

摘要： An internal combustion engine, particularly suitable for use in a work machine, is provided with an exhaust manifold, a turbocharger, and a bypass venturi assembly. The turbocharger includes a turbine and a compressor, with the turbine having a variable geometry inlet coupled with the exhaust manifold, and the compressor having an outlet. The bypass venturi assembly includes a housing having an outlet, a combustion air inlet and an exhaust gas inlet. The combustion air inlet is coupled with the compressor outlet. The exhaust gas inlet is coupled with the exhaust manifold. A center piece is positioned within the housing and is in communication with the combustion air inlet. The center piece defines a combustion air bypass section therein. A combustion air bypass valve is positioned in association with the combustion air bypass section. The exhaust gas valve is positioned in association with the exhaust gas inlet. The variable geometry inlet of the turbine allows the pressure ratio of the compressed combustion air to be varied, thereby improving the mixing efficiency of the exhaust gas with the combustion air.

摘要： The present invention relates to a fuel injecting apparatus for an internal combustion engine, in which exhaust gas is applied to the injection of fuel. According to the fuel injecting apparatus, a portion of hot exhaust gas is introduced in front of the outlet of the fuel injector allowing hot exhaust gas to promote the fine particle formation and vaporization of fuel thereby enhancing efficiency of fuel. Again, a portion of exhaust gas can be circulated into the combustion chamber to restrict the production of nitrogen oxide. Also, exhaust gas re-introduced into the combustion chamber through the EGR line is cooled by heat of vaporization of fuel injected from the fuel injector thereby advantageously relieving the installation of an additional cooling system for cooling exhaust gas which is re-circulated into the combustion chamber.

摘要： An exhaust gas recirculation system for an internal combustion engine. The present invention includes a turbocharger, restrictor valve, and exhaust gas recirculation valve. The restrictor valve is upstream of the turbine of the turbocharger, and restricts the flow of exhaust gas into the turbine. This restriction results in an increase in pressure of the exhaust gas provided to the restrictor valve. The increased pressure exhaust gas is provided to the inlet of an exhaust gas recirculation valve which may be actuatable independently of the actuation of the restrictor valve. The restrictor valve may be modulated until exhaust pressure is greater than the pressure of the intake gas. The restrictor valve creates a pressure differential suitable for recirculating a portion of exhaust gas through the EGR valve and into the intake manifold of the engine. The restrictor valve may also be operated without recirculation of exhaust gas, such as during cold starting of a diesel engine so as to increase the load on the engine and decrease the warm-up time of the engine. Some embodiments of the present invention utilize an electronic controller for operating the restrictor valve and the EGR valve.
摘要翻译：一种用于内燃机的废气再循环系统。本发明包括涡轮增压器，限流阀和排气再循环阀。限流阀在涡轮增压器的涡轮机的上游，并限制排气流入涡轮。这种限制导致提供给限流阀的废气的压力增加。增加的压力排气被提供到废气再循环阀的入口，废气再循环阀可以独立于限制阀的致动而致动。限流阀可以被调制直到排气压力大于进气的压力。限流阀产生适于使排气的一部分再循环通过EGR阀并进入发动机的进气歧管的压力差。限制阀也可以在废气再循环的情况下运行，例如在柴油发动机的冷起动期间，以增加发动机的负荷并减少发动机的预热时间。本发明的一些实施例利用电子控制器来操作限流阀和EGR阀。

摘要： A device for controlling the admission of additional gas, such as exhaust gas, to the induction tube of the engine so that additional gas quantities are admitted to the induction tube only during partial load operation. The device includes an additional gas quantity valve situated within the induction tube. The valve includes, in its various embodiments, structure to assure a high tolerance factor in the engagement of the valve seat and the movable valve member so that wear and temperature effects will not adversely affect the control of the additional gas quantity flow.

摘要： A valve assembly comprises: a valve housing comprising an interior cavity having upstream side and a downstream side; and a valve member movable within the valve housing between a closed position in which flow between the upstream side and the downstream side is prevented or substantially prevented and one or more open positions in which flow between the upstream side and the downstream side is enabled. The valve assembly further comprises: a sensor mounting flange on an exterior surface of the valve housing; a first bore in the valve housing linking the upstream side of the valve housing and the sensor mounting flange; and a second bore in the valve housing linking the downstream side of the valve housing and the sensor mounting flange; such that a sensor configured to measure a differential between the upstream side and the downstream side is mountable directly on the valve assembly.

摘要： Methods and systems are provided for adjusting an exhaust gas recirculation (EGR) valve based on a final EGR estimate. In one example, a method may include adjusting the EGR valve based on a final EGR flow estimate, the final EGR flow estimate based on a first EGR flow estimated with a differential pressure sensor across the EGR valve, a second EGR flow estimated with an intake oxygen sensor, and accuracy values of each of the first and second EGR flows. The accuracy value may be based on engine operating conditions during estimation of the first and second EGR flows.
