    • The apparatus is comprised of two sensors of the thermal type (11a, 11b) made of materials resisting without any alteration to a temperature of 650 DEG C. Probes (15a, 15b) are controlled by a microprocessor (16) to come periodically and momentarily in contact with said sensors in order to calculate (through microprocessor (16)) the thermal time constant of said sensors presenting a deposition layer of environmental pollutants. The microprocessor (16) compares the value of said time constant with an order value that commands the closure of a shunt switch (17) of a resistance (18) which, when short-circuited, determines a reinforced heating of the sensors to bring them to a temperature of incineration of organic materials originating from the pollution of the ambient medium and deposited on said sensors. Thus, the sensors are maintained in the cleanliness conditions of their surface, thereby providing for the accuracy of information supplied by said sensors outside cleaning periods.

    • PURPOSE: A surface velocity measuring system using the associative analysis of space time images and a method thereof are provided to enable 2D velocity analysis by calculating a displacement of an image through associative analysis. CONSTITUTION: A test point designating and image extracting unit (1200) designates test points (p,g) from n pieces of images and extracts an image having a size designated for each direction based on the test points. An extracted image synthesizing and time space image composing unit (1210) extracts an image from an image photographed at t + Δt time to compose a time space image. An image displacement calculating unit (1230) calculates an image displacement of four directions by using a parabolic peak interpolation. A main flow direction determining unit (1240) determines a main flow direction based on the calculated image displacement. A 2D velocity distribution determining unit (1250) determines 2D velocity distribution by selecting a direction vertical to a main flow direction and calculates the coordinate conversion of a slope image and the velocity (u,v) of directions (x,y).

    • Fuel is supplied to an internal combustion engine depending on the operation of a fuel control valve. A hot-wire type intake air quantity sensor is disposed in an air-intake passage for the engine to detect the quantity of air passing through it. A devie heats a hot wire at a temperature higher than a temperature in the normal operation so as to burn off a deposit on the hot wire by detecting the output of the sensor indicating that suction of air to the engine is stopped, after the engine has been stopped. The wire is heated for a predetermined time after the direction of the output of the sensor indicating that suction of air has been stopped.

    • PROBLEM TO BE SOLVED: To provide an air flow measurement device in which en external determination circuit and an exclusive harness for instructing heat cleaning are unnecessary, and power supply after stop of an engine is unnecessary.SOLUTION: When an air flow measurement device receives energization, heat cleaning means 4 provided in an energization control circuit 3 executes heat cleaning for temporarily making a temperature of an exothermic heater 2 higher than that in air flow measurement. Specifically, the temperature of the exothermic heater 2 is raised to an approximately fixed target temperature on the basis of an intake air temperature. Thus, since the air flow measurement device executes the heat cleaning when receiving the energization, an external determination circuit and an exclusive harness for instructing the heat cleaning can be abolished to suppress costs. In addition, since the air flow measurement device executes the heat cleaning when receiving the energization, power supply after stop of an engine is made unnecessary to suppress the costs.
    • 要解决的问题:提供一种空气流量测量装置,其中不需要用于指示热清洁的外部确定电路和专用线束,并且不需要发动机停止后的供电。 解决方案:当空气流量测量装置接通通电时,设置在通电控制电路3中的热清洁装置4执行用于暂时使放热加热器2的温度高于空气流量测量的热清洗。 具体地说,根据进气温度,放热加热器2的温度上升到近似固定的目标温度。 因此,由于气流测量装置在接收到通电时执行热清洗,因此可以消除用于指示热清洁的外部判定电路和专用配线,以抑制成本。 此外,由于气流测量装置在接收到通电时执行热清洗,所以不需要发动机停止后的供电来抑制成本。 版权所有(C)2013,JPO&INPIT
