    摘要： The invention relates to an engine electronic control unit (1) that is inserted through a through hole provided in an intake pipe and mounted in an intake air passage (3) in a direction substantially perpendicularly with respect to a plane of the intake pipe forming the intake air passage (3). This unit is then secured to the intake pipe using a fixing flange (22) provided at a connector portion (21). A fixing rail (5) is protruded inside the intake pipe and leading edges of a metal base (12) and a metal cover (13) of the unit are inserted into this rail, thereby securing in position an end opposite to a side of the connector portion (21) of the unit. This realizes an engine electronic control unit offering an outstanding heat radiation performance and vibration resistance, without having to provide special heat radiating parts or without involving an increase in an intake air resistance within the intake air passage (3). By using such an engine electronic control unit, it is possible to provide a low-cost, compact engine air intake system.

    摘要： The invention relates to a mass airflow measuring apparatus (3) in which the effect of the adhesion onto the heating resistor (1) caused while the engine is off is reduced and the measuring accuracy is improved. The apparatus measures the mass airflow of the air sucked into the internal combustion engine, using the heating resistor (1). The power control circuit (4) maintains the heating resistor (1) temperature equal to or higher than the temperature during the operation of the internal combustion engine after the internal combustion engine has stopped and until the temperature of the internal combustion engine and its apparatuses installed in the suction system has lowered below the generation temperature of volatile gas such as oil vapor. The power control circuit (4) using the temperature sensing resistor (2) that detects the temperature of the air sucked into the combustion engine, detects the air temperature and maintains the heating resistor (1) temperature, based on the temperature measured, equal to or higher than the temperature during the operation of the internal combustion engine even after the internal combustion engine has stopped.

    摘要： The invention relates to an air flow meter which can decrease the error due to the backflow. Throttle valve (17) which opens and shuts the air intake passage (19) is installed in the air intake passage (19) of the internal combustion engine (1). The first sensor part (161) is installed in the air intake passage (19) in the upstream of throttle valve (17). Further, the second sensor part (141) is installed-in the air intake passage (19) in the downstream of throttle valve (17). Pulsation compensating means (671) corrects the pulsation of the air flowrate signal detected by the first sensor part (161) by using the output signals of the first and the second sensor parts (161, 141) based on each cylinder of the internal combustion engine (1).
