摘要： An exhaust gas recirculator wherein a double diaphragm type flow control valve is disposed in a recirculating passage which couples an exhaust system and an intake or suction system of an internal combustion engine. The flow control valve includes first and second diaphragms, and is formed with a first pressure control chamber partitioned by a first diaphragm and a second pressure control chamber partitioned by the first diaphragm and a second diaphragm. Vacuum is introduced into the first and second pressure control chambers from vacuum ports provided in the vicinity of a throttle valve of a carburetor. Thus, the stroke of a valve shaft of the flow control valve and accordingly the opposing area between a valve body and valve seat of the flow control valve are controlled in two stages, so that the single flow control valve can control the amount of recirculative exhaust gas in two stages.

摘要： Controlled exhaust gas recycling can be accomplished by a pneumatically actuated valve which restricts the flow of exhaust gas from an exhaust manifold of an internal combustion engine to the intake manifold. Exhaust gas may be removed from the manifold and enters a pressure chamber through a reduction means, such as an aperture in a plate. The effective cross-sectional area of hydrodynamic flow of the reduction means is chosen to be greater than the effective cross-sectional area of hydrodynamic flow of the valve. The valve is actuated by a diaphragm control means which is coupled to the intake and exhaust manifold. The diaphragm control means controls the amount of partial pressure applied to the pneumatically actuated valve according to the exhaust pressure from the exhaust manifold. Thus, the ratio of exhaust gas recycled through the internal combustion engine relative to the amount of engine air intake, decreases as the air intake volume increases, such as when the engine is under high loads or operating at high rates (RPM).
摘要翻译： 受控的废气再循环可以通过气动致动的阀来实现，其将排气从内燃机的排气歧管的流量限制到进气歧管。 废气可以从歧管移除并通过诸如板中的孔的还原装置进入压力室。 选择还原装置的流体动力流动的有效横截面面积大于阀的流体动力流动的有效横截面面积。 该阀由隔膜控制装置致动，隔膜控制装置联接到进气歧管和排气歧管。 隔膜控制装置根据来自排气歧管的排气压力来控制施加到气动致动阀的分压量。 因此，通过内燃机再循环的废气相对于发动机进气量的比例随着进气量的增加而减小，例如当发动机处于高负荷或高速运转（RPM）时）。

摘要： An exhaust pressure regulating system for use with an exhaust gas recirculating system of an internal combustion engine, and particularly for an automobile, utilizing a control valve of the butterfly or poppet type in the exhaust pipe for adjusting the back pressure in the exhaust, a vacuum-sensitive device for actuating the control valve, a pressure-signal passage for applying the pressure in the intake manifold to the vacuum-sensitive device and a pressure-comparing valve sensitive to the quantity of air being taken into the engine and the adjusted back pressure in the exhaust for modulating the pressure in the pressure-signal passage. The pressure-comparing valve includes a pair of interlocked diaphragms actuated in opposed relationship interacting with a biased valve member in the pressure-signal passage, one of the interlocked diaphragms being actuated by the venturi vacuum pressure created by the quantity of air being taken into the engine through the carburetor and the other of the diaphragms being actuated by the adjusted back pressure and tending to open the valve and bleed-off pressure in the pressure-signal passage. A booster valve is preferably used to amplify the venturi vacuum pressure and a pressure-changeover valve, sensitive to operating conditions of the engine, may be disposed in the pressure-signal passage.

摘要： Herein disclosed is a flow control valve assembly for use in an exhaust gas recirculation system in which engine exhaust gases are recirculated from the exhaust system to the intake system of an internal combustion engine so as to clean the engine exhaust gases. The flow control valve assembly comprises a first valve interposed between its inlet and outlet ports for regulating its effective area for the exhaust gases. The first valve includes an orifice, a valve seat, a constant-pressure chamber defined inbetween, and a valve member movable between a seated position and an open position. The control valve assembly further comprises diaphragm means for acutating the valve member and including a diaphragm connected to the valve member, a diaphragm chamber having fluid communication with an air source under pressure, and an air bleed hole formed in the diaphragm. The control valve assembly further comprises a second valve including a valve member, which is movable between a seated position and an open position in response to the pressure in the constant-pressure chamber for regulating the effective area of the air bleed hole, so that the amount of air bleed may be controlled by the second valve to maintain the pressure of the exhaust gases in the constant-pressure chamber substantially at the atmospheric level. Thus, the control valve assembly can provide such recirculation of the exhaust gases as is proportional to the amount of the intake mixture.

摘要： An apparatus for recirculating exhaust gases, wherein an exhaust gas recirculating passage provides communication between the intake and exhaust passages of an internal combustion engine. A constriction is provided in the passage, and a control valve is provided in the passage downstream of the constriction. A negative control pressure passage introduces a negative control pressure from a port in the intake passage to the control valve. A pressure chamber is interposed between the constriction and the control valve, which pressure chamber has a pressure therein which is substantially equal to atmospheric pressure when the control valve is opened and to that in the exhaust passage when the control valve is closed. A first operating valve opens the negative control pressure passage to the atmosphere when the pressure in the pressure chamber becomes substantially atmospheric. A second operating valve, which is responsive to the amount of sucked air flowing through the intake passage, opens the negative control pressure passage to the atmosphere when the pressure in the intake passage exceeds a predetermined negative pressure.

摘要： A position detector for detecting the piston TDC position in a piston engine has a cylindrical casing penetrating the top wall defining a combustion chamber of the engine and fixed thereto, a light emission element, a light reception element each being accommodated within the upper half of the casing, an inlet optical fiber connected to the light emission element and an outlet optical fiber connected to the light reception element. These optical fibers are inserted into the lower half of the casing. The lower end of each optical fiber is opposed to the upper surface of the piston at a predetermined distance therefrom when the piston is located in the vicinity of the TDC position. The light emitted by the light emission element is applied to the upper surface of the piston, after passing the inlet optical fiber. The reflected light from the upper surface of the piston is received and sent to the light reception element by the outlet optical fiber. The light reception element transmits a light reception signal corresponding to the amount of the received light to the detecting circuit. The detecting circuit detects peaks of the light reception signal, which appear before and after the piston TDC position, calculates the half of the rotating angle of a crankshaft between two adjacent peaks and transmits a TDC piston detecting signal when the crankshaft rotates by the calculated rotating angle from the time the preceding peak out of two adjacent peaks appearing in the following period is detected.
