摘要： Air flowing through an air cleaner is passed through a main passage and drawn into an internal-combustion engine, with a part of the air flowing through the main passage flowing into a by-pass passage having an air flow sensor mounted therein. A length of the by-pass passage is substantially three or more times longer than that of a part of the main passage corresponding thereto. Accordingly, even when the internal-combustion engine is operated with a throttle nearly totally open and the air in the main passage is pulsated, the average flow rate in the by-pass passage increases due to the inertial lag effect obtained by lengthening the by-pass passage, so that it is possible to prevent the output of the flow sensor from being undesirably lowered.

摘要： A method and apparatus are disclosed for measuring atmospheric pressure in conjunction with an air-fuel ratio sensor of the type comprising a concentration cell with atmospheric air and exhaust electrodes on opposite sides of a solid-state electrolyte having oxygen ion conductivity. During an atmospheric pressure measuring cycle, oxygen ions are pumped from the atmospheric air electrode to the exhaust electrode, in a quantity which is either predetermined at a fixed value, or is sufficient to bring the cell to an equilibrium state. Atmospheric pressure is then calculated from measured emf of the cell, using an experimentally derived functional relationship. In a second embodiment, ions are pumped until a predetermined change of the concentration cell emf is achieved, and atmospheric pressure is determined based on the amount of time required to achieve such change. The atmospheric pressure measuring mode is operated on a time shared basis with the air-fuel ration detection mode.

摘要： A thermal air flow meter consists essentially of a hollow cylindrical support made of an insulating material, a heat-sensitive resistor formed on top of the support, and lead wires inserted into the hollow part of the support from either end and bonded thereto by glass. This flow meter measures the flow rate from changes in the resistance of the heat-sensitive resistor with temperature. The ratio of the inner diameter d.sub.2 of the support to the outer diameter d.sub.3 of the lead wires (d.sub.2 /d.sub.3) is at least 1.7. This arrangement can provide a thermal air flow meter with a quick response to changes in flow rate.

摘要： An intake barrel connected to an intake pipe of an internal combustion engine is provided therein with a venturi member. Openings are formed in the wall of the intake barrel at the upstream and downstream sides of the venturi member. A bypass passage forming member provided with a groove of a length greater than the distance between said openings is fixed to the outside of the intake barrel. A bypass passage is formed by these openings and the groove. A spacer is interposed between the intake barrel and the bypass passage forming member. The cross-sectional area of the bypass passage can be varied by varying the thickness of the spacer.

摘要： A thermal air flow meter is equipped with a flow rate detector utilizing the phenomenon that heat is carried away in proportion to flow rate. The flow rate detector comprises a support, a heat-sensitive resistor formed on the support and leads attached to both ends of the support. To make the temperature distribution uniform, the heat-sensitive resistor is formed in such a manner that the resistance per unit length of the heat-sensitive resistor at either end of the support is greater than the resistance per unit length of the heat-sensitive resistor at the center of the support. This arrangement can provide a thermal air flow meter which has a rapid response to changes in flow rate.

摘要： An air flow rate sensor including a resistor the characteristic of which depends on temperature for operation mounted in a suction conduit of an internal combustion engine. The air flow rate sensor includes a tube of inorganic material, a platinum wire wound in convolutions on the surface of the tube, and a glass coating applied at least to the surface of the resistor while allowing a part of the surface to be exposed. The glass coating has a thickness smaller than the diameter of the resistor wire and enables equalization of pulsations of the sensor output to be obtained because of the thermal capacity of the glass coating.
