摘要： A preferred embodiment EGR valve permits exhaust gas to be induced into the intake line downstream of the compressor, while minimizing the need to reduce the size of the turbocharger. The preferred embodiment EGR valve exploits variations around the mean pressure in the EGR passage created by the engine cycle by selectively opening when the pressure in the EGR valve exceeds the pressure in the intake line. Thus, exhaust gas is recirculated even when the engine is running near torque peak. The preferred embodiment EGR valve also exploits the higher mean pressure in the exhaust line relative to the intake line at higher engine speeds by remaining open, in order to minimize the energy consumed in opening and closing the EGR valve.
摘要翻译：优选的实施方案EGR阀允许排气被吸入到压缩机下游的进气管路中，同时最小化减小涡轮增压器尺寸的需要。 EGR阀利用在发动机循环所产生的EGR通路中的平均压力周围的变化，当EGR阀中的压力超过进气管线中的压力时，选择性地打开EGR阀。因此，即使当发动机在扭矩峰值附近运行时，废气也被再循环。在优选实施例中，EGR阀还通过保持打开来利用在较高发动机转速下相对于进气管线的排气管线中较高的平均压力，以便最小化打开和关闭EGR阀时消耗的能量。

摘要： A variable displacement high pressure pump having a plurality of high pressure pumping units which receive fuel from a low pressure fuel pump. A rotary cam-driven roller tappet, for producing pumping displacement of the pumping plunger of a respective pumping element, is connected to the pumping plunger by a separated link in a manner permitting the pumping plunger to float relative to the roller tappet during at least a portion of each pumping cycle. As a result, the capacity of the pumping chamber can be limited to an extent that is less than the full stroke achievable by the pumping plunger being retracted to the maximum extent which is permitted by the driving cam. In this way, the quantity of fuel to be pressurized and injected into the common rail does not have to be determined by a cutting-off of a spilling flow of excess metered fuel during the compression stroke of the pumping plunger, so that a low pressure solenoid valve can be used, in the case of time-stroke and time-pressure metering, and no solenoid is required to control metering in the case of pressure-time metering.

摘要： A fuel distributor is provided which is capable of distributing fuel through plural fuel injection lines to the corresponding cylinders of a multicylinder internal combustion engine and which includes a distributor housing including a supply inlet passage, a plurality of fuel injection outlet passages and a plurality of distributor valves for providing sequential periodic fluidic communication between the supply inlet passage and the outlet passages. Each distributor valve, which may be cam-actuated or solenoid-actuated, is adapted to be placed in an open position to define a fuel injection period during which high pressure fuel may flow through the distributor valve to the respective engine cylinder and a closed position blocking fuel flow through the respective fuel injection outlet passage. Each of the distributor valves is adapted to receive a force from the high pressure fuel flowing from the supply inlet passage which urges the distributor valve into the closed position thereby providing an effective seal and minimizing leakage. The distributor may be used in a high pressure fuel system having a control valve positioned between a high pressure accumulator and the fuel distributor for controlling the flow of high pressure fuel to the distributor. The control valve is moveable to define a fuel injection event, occurring within the injection period provided by each distributor valve, during which high pressure fuel may flow from the high pressure supply means through one of the distributor valves to a respective engine cylinder.

摘要： An electronically controlled fuel supply system is provided for employing a plurality of fuel injectors which maximize SAC pressures under both low speed and high speed operating conditions and are capable of sustaining SAC pressures in excess of 30,000 psi. The fuel supply system of the present invention includes a gear pump which supplies pressure-modulated fuel to a fueling channel and to a timing channel and from there to a plurality of injectors. Fuel pressure regulator means and timing fluid pressure regulator means are provided in the fueling and timing channel, respectively. An electronic control unit receives information relating to engine operating conditions from a plurality of sensors and actuates the fuel pressure regulator means and the timing fluid pressure regulator means to adjust the pressure as required for the specific engine operating conditions. The timing fluid is delivered to the injectors by the present system at a pressure sufficient to sustain a hydraulic link within the injector of the length necessary to maintain high SAC pressures during injection. Several embodiments of a fuel supply system which achieves these objectives are disclosed. A mounting integral with the cylinder head for an electronically controlled injector fuel supply system is also provided.

摘要： This disclosure deals with an aneroid for an internal combustion, compression-ignition engine including a turbocharger. The engine further includes a fuel supply system including a fuel supply rail connected to carry fuel to a plurality of fuel injectors and a regulator for regulating the pressure of the fuel in the supply rail. The quantity of fuel injected in each operating cycle of the engine is a function of the fuel pressure in the supply rail. The aneroid is connected in the rail between the regulator and the injectors, and it includes valve means operative to gradually increase the fuel pressure in the rail downstream of the aneroid, in response to a rise in manifold air pressure. The aneroid further includes means responsive to the downstream fuel pressure for adjusting the valve means to reduce the fuel pressure in response to a rise in the downstream fuel pressure.

摘要： The disclosure illustrates a fuel mileage indicator which gives a dynamic reading of the fuel mileage for a vehicle powered by an internal combustion engine. As a result it indicates to the driver whether he is driving efficiently and is conserving fuel. The device consists of a variable resistance device responsive to a fuel system parameter or other engine parameter which is proportional to engine fuel flow. This variable resistance device is connected in series with a generator having a D.C. voltage output directly proportional to vehicle speed. An ammeter indicates current through the circuit and is calibrated to give an output of miles per gallon.

摘要： A cam follower assembly for mechanically connecting a cam on a camshaft to a push rod assembly is disclosed. The cam follower assembly includes a cam follower link rotatably mounted to a pivot at a first end. At a second end the cam follower link has a substantially semicylindrical recess having a thin axial wall formed at each end of the recess. The cam follower link contacts a push rod adjacent its second end on a surface opposite the surface having the substantially semicylindrical recess. A pinless roller is mounted within the substantially semicylindrical recess and is restrained from axial movement by the thin axial walls. The pinless roller is held in rolling contact with a corresponding cam by imposition by the link of restraining force directly on the cam engaging surface of the roller. The roller may include an annular groove to facilitate lubrication of the cam follower assembly.

摘要： A fuel injector of the open nozzle type, which is capable of achieving SAC pressures in excess of 30,000 psi during injection. The injector assembly of the preferred embodiments includes a plunger assembly having three plungers arranged to form a hydraulic, variable timing fluid chamber between upper and intermediate plungers and an injection chamber below a lower plunger. To prevent leakage from the injection chamber, the fuel supply passage is provided, along with the injection chamber, within a one-piece injector cup and a predetermined minimum seal length, at commencement of injection, between a land portion of an injection plunger and a wall surface defined by a bore of the injector within which it reciprocates is coordinated to the dimensions of the bore below the land and a predetermined maximum solid fuel height for the injector to result in the minimum seal length being at least one-half of the maximum solid fuel height. To obtain an increase in SAC pressures under low speed operating conditions without exceeding pressure capabilities under high speed conditions, some embodiments have valve arrangements for draining timing fluid from the timing chamber whenever the pressure of the timing fluid therein exceeds a predetermined value.
