摘要： An air-fuel ratio compensating apparatus for the carburetor of an internal combustion engine has first and second valves having equal control (input) current-opening characteristics and provided in main and slow system air bleed paths respectively to control sectional area of flow in the main and slow system air bleed paths in relation to the output of an air-fuel ratio sensor, electronic control circuit which sends the control current to the first and second valves in such a way that the opening of the second valve is always larger than that of the first valve. Thus, flow of the main system air bleed is restrained during the initial part of the acceleration period so as to reduce the amount of noxious component in the exhaust gas.

摘要： A fluid control valve assembly for controlling the flow of fluid passing through a fluid passageway defined in a valve body and having an inlet end and an outlet end. A bellows formed of low tackiness material has fixed one end wall secured to the valve body and the other movable end wall connected to a valve stem. The valve stem is actuated by an actuator to move the other movable end wall of the bellows between a closed position in which the other movable end wall is brought into direct contact with a valve seat located in the fluid passageway and an open position in which the other movable end wall is brought out of engagement with the valve seat.

摘要： The invention is directed to an arrangement for sealing a clearance between a cylinder head and a cylinder block of an engine with a metal gasket clamped therebetween. The metal gasket is formed of a metallic base plate which has a plurarity of openings and beads formed therearound. The base plate may include annular shims welded on the base plate around the openings and a resilient sealing member deposited on the base plate surrounding the openings. The gasket may be disposed in such a manner as to place tip ends of the beads toward the cylinder block which causes a smaller displacement relative to the beads in comparison with the cylinder head. The resilient sealing member may be arranged to have a section of different dimension between a portion located at a side facing the beads and other portion at the opposite side thereof, or between a portion located at a junction where two of the beads meet and other portion.

摘要： A metal gasket having first and second base plates made of metal. In each base plate, at least an opening is defined and a bead is formed around the opening. The second base plate is disposed in parallel with the first base plate with the tip ends of the beads of the first and second base plates facing each other. An annular metallic shim is secured to the first base plate at the side of the bead between the inner periphery of the bead and the opening. And, a resilient sealing member is deposited on the second base plate at the side of the bead around the outer periphery of the bead. A non-vulcanized coating layer of fluoro rubber containing no vulcanizing agent may be deposited on the entire surface of the second base plate at the side of the bead. A vulcanized fluoro rubber may be deposited on the non-vulcanized coating layer at the side of the bead around the outer periphery of the bead.

摘要： An electromagnetic fluid flow control valve mechanism has a hollow slide valve linearly movable on and along a core in response to energization of a coil disposed around the slide valve for selective fluid communication between a inlet port and first and second outlet ports through a chamber in a casing. The ratio of a cross-sectional area of the inlet port to that of each of the first and second outlet ports is selected such that the chamber will develop a relatively small vacuum such as of 20 mmAg at maximum. Preferably, the ratio is 6.5 or greater. This arrangement prevents a fluid, typically air, from flowing from the second outlet port back into the chamber.

摘要： Disclosed is a suction pipe pressure detection apparatus for detecting suction pipe pressure of a multi-cylinder type internal combustion engine provided with a throttle valve in the suction pipe of each of the cylinders, or a so-called independent suction type internal combustion engine. The apparatus detects the suction pipe pressure for just a few cylinders out of the total number of cylinders, makes proper corrections to the detected data in accordance with the throttle valve opening, engine speed of the internal combustion engine, etc., and, during the period before the next detection of the suction pipe pressure is made, accurately computes, using the above data, the suction pipe pressure for the cylinders, under the suction stroke, for which the pressure is not actually detected. That is, the throttle opening and the engine speed of the internal combustion engine are detected at intervals of shorter periods of time than those intervals at which the suction pipe pressure is actually detected, and correction is continuously made to the earlier detected suction pipe pressure according to the above detected data. The present invention enables a high-degree controlling of the internal combustion engine by making highly accurate suction pipe pressure data available at rather high frequency, and by further continually providing the intake air quantity, and the fuel injection amount, with considerable high accuracy.
摘要翻译：公开了一种用于检测在每个气缸的吸入管中设置有节流阀的多缸型内燃机的吸入管压力的吸入管压力检测装置或所谓的独立的吸入型内燃机。该装置根据节气门开度，内燃机的发动机转速等，在总气缸数中检测出吸气管压力仅为几个汽缸，对检测到的数据进行适当的校正，在进行下一次检测吸入管压力之前的时间段，使用上述数据精确地计算在实际检测到压力的吸入冲程下的气缸的吸入管压力。也就是说，与实际检测吸入管压力的间隔相比，以较短的时间间隔检测内燃机的节气门开度和发动机转速，并且根据以前检测到的吸入管压力连续进行校正到上述检测到的数据。本发明能够通过以相当高的频率提供高精度的吸入管压力数据，并且以相当高的精度进一步连续地提供进气量和燃料喷射量，能够高度控制内燃机。
