摘要： A fuel metering valve assembly includes an air flow metering member which actuates the movable part of a fuel metering valve. Depending on the displacement of this movable part, two cooperating openings, a control slot and a shaped control orifice, together define the effective flow cross section for the fuel delivered to the engine. In order to improve the resolution of the path of the moving part of the valve assembly, one of the cooperating openings, e.g. the control orifice, is formed as a triangular opening in a sleeve or bushing surrounding an axially slidable shaft which supports the air flow rate-responsive member. The triangular opening may also be defined within the wall of the shaft. The width of the control slot is defined by a spacer ring between two coaxial partial bushings and one edge of the triangular opening is defined by the oblique line separating two partial sleeves.

摘要： For detoxicating the exhaust gases of an internal combustion engine an in-series arrangement of a first reactor and an oxidizing reactor is provided with the exhaust line of the engine along with an oxygen measuring element and structure for producing two additional air streams fed to the exhaust line. The first reactor reduces the nitrogen oxides in the exhaust gas and the second or oxidizing reactor oxidizes the hydrocarbons and the carbon monoxide in the exhaust gas. The oxygen measuring element is mounted to the exhaust line and regulates the mass ratio of air to fuel on the suction side of the engine. The first additional air stream is injected into the exhaust pipe in the flow direction upstream of the oxygen measuring element. The quantity of this air stream is regulated and corresponds to the fuel throughput of the engine so that when the oxygen measuring element measures a stoichiometric mixture (.lambda.=1) a slightly rich air-fuel mixture (.lambda. .apprxeq.0.98-0.99) is supplied to the engine.BACKGROUND OF THE INVENTIONThe present invention relates to a process and system for detoxicating the exhaust gases of an internal combustion engine, the exhaust pipe of which contains an in-series arrangement of a first reactor for reducing the nitrogen oxides in the exhaust and a second reactor for oxidizing the hydrocarbons and the carbon monoxide in the exhaust. This process operates with a first control system which regulates the mass ratio of air to fuel on the intake side of the engine as a function of the quantity measured by an oxygen measuring element disposed in the exhaust pipe and with at least a second control system which controls the injection of supplementary air into the exhaust pipe in the direction of flow upstream of the oxidizing reactor.With exhaust gas detoxicating systems of this type comprising two bed catalysts, to obtain satisfactory reduction of the nitrogen oxides NOx, the air-fuel mixture supplied to the engine should be slightly richer (.lambda.

摘要： A continuous fuel injection system for metering out fuel to the induction tube of an internal combustion engine. An air flow metering assembly in the induction tube includes a baffle plate which is set with its plane perpendicular to the air flow vector and is mounted on a shaft which slides axially in bearings. As a result of the air flow, the baffle plate is displaced axially to varying extent and this displacement is opposed by a restoring force provided by pressurized fuel and subject to adjustment on the basis of engine variables. A vaned impeller wheel, mounted on the baffle shaft, causes rotation of the shaft in the bearings, thereby eliminating static friction and preventing hysteresis effects. The centrifugal forces generated by the rotation aid in distributing the fuel and in admixing it with the incoming air.

摘要： A fuel injection pump for internal combustion engines, in particular an in-line injection pump for Diesel engines, is proposed having an injection quantity governor and an electrically driven feed pump, in which in order to assure an emergency shutoff in the event of a malfunction of the injection quantity governor, a check valve, the forward flow direction of which is toward a suction chamber filled with fuel by the feed pump, is disposed between the pressure-side outlet of the feed pump and the suction chamber. An emergency shutoff device responding to a malfunction switches off the feed pump drive, so that because of the lack of feed pressure the check valve closes and blocks off the suction chamber. The engine comes to a stop, as soon as a partial vacuum is established in the suction chamber, which occurs as soon as several revolutions later.

摘要： A method and an apparatus are proposed for determining and controlling an exhaust gas recirculation rate in internal combustion engines (Diesel engines), wherein an adjusting member in the exhaust gas recirculation line is adjusted by a regulator in order to attain precise regulation of the exhaust gas quantity recirculated to the aspirated air zone. The regulator is supplied with the exhaust gas temperature (T4) measured at a given time as the load signal for the engine. The comparison value of the regulator is then either an actual value of the exhaust gas recirculation rate, ascertained by means of effective temperature measurements in the intake zone of the engine, or a set-point differential temperature which is produced by means of measuring the aspirated air quantity at a given time and the rpm.

摘要： A regulator shaft, rotary centrifugal weights, and a governor member which is slidable on the regulator shaft, are arranged in a pressurized, fuel-filled inner chamber of a fuel injection apparatus. The centrifugal weights engage regulator springs via the governor member and a control sleeve. The governor member is closed adjacent the free end of the regulator shaft except for a throttle opening for communication with the inner chamber. The governor member is provided with a work chamber, one extremity of which is limited by the regulator shaft. A conduit leading to a fuel tank communicates with the work chamber. A magnetic valve connected to an electronic control device for control of the fuel flow is provided in the conduit. Opening the magnetic valve causes a pressure drop in the work chamber which in turn causes the governor member to press against the centrifugal weights, thus enhancing the fuel injection quantity so as to reduce deviations from those desired and pre-set.
