摘要： PURPOSE:To improve response to a large extent, by the constitution wherein a heat transfer heater and the contact part of a temperature dependent resistors and a supporting body are coated or separated from air. CONSTITUTION:An electric heater 1 and first and second temperature dependent resistors 3 and 2 are connected to an electric circuit. A bridge is formed by the temperature dependent resistors 3 and 2 and two fixed resistors 9 and 10. Since the first temperature dependent resistors 3 is subject to the effect of the heater 1, the balance of the bridge is lost. The electric circuit always applies a current to the heater so that the amount of unbalance becomes constant. With this current as an output, the amount of air is measured. An electric insulator 6 is provided so that a contact part 5 of a supporting body 4 and a platinum resistor wire is coated or separated from the flow of the air. Thus, the temperature change at the contact part of the supporting body and the platinum resistor wire can be meade small, and the response can be improved to a large extent.
摘要翻译：目的：为了在很大程度上改善响应，通过将传热加热器和温度依赖性电阻器和支撑体的接触部分与空气涂覆或分离的构造。构成：电加热器1和第一和第二温度依赖电阻器3和2连接到电路。由温度依赖电阻器3和2以及两个固定电阻器9和10形成桥。由于第一温度依赖电阻器3受到加热器1的影响，桥接器的平衡将丧失。电路总是向加热器施加电流，使得不平衡量变得恒定。以该电流作为输出，测量空气量。设置电绝缘体6，使得支撑体4的接触部分5和铂电阻器线材从空气的流动被涂覆或分离。因此，支撑体和铂电阻器线的接触部分的温度变化可能很小，并且可以在很大程度上提高响应。

摘要： PURPOSE: To accurately measure the amount of air, by obtaining a pulsation component from a differentiated value of the output of a hot-wire air flow meter so as to correct the output of the air flow meter, in the case of a method in which a fuel supply amount or ignition timing is controlled in accordance with the output of said hot-wire air flow meter.
CONSTITUTION: A difference of air flow |ΔG| is obtained from an air amount signal after performing its AD conversion and linearization in a routine called at every 4ms. This difference corresponds to a differentiated value of the air amount signal. The difference |ΔG|, being periodically obtained, can be said the differentiated value sampled at random for intake pulsation because the intake pulsation is synchronously generated with rotation. A maximum value ΔGm among those values is allowed to represent the pulsation amplitude. Ignition timing and a fuel supply amount are corrected by the maximum value ΔGm. In this way, an air amount can be accurately measured.

The output terminal part of the bridge circuit, i.e., a connection point between the element 12 and a resistor 14 and a connection point between resistors 15 and 16 are connected to a comparator 18 to compare voltages, fed to the two output terminal parts, with each other. An air temperature measured by the element 13 is set such that an output signal from the comparator 18 rises under a state in that the temperature of the element 12 is increased to a specified temperature state.
