    摘要： There is provided an air flow meter (7) for detecting the flow rate of air, an electronically controlled throttle (13) for opening and closing a throttle valve and a calculating device (14, 801) to which a target engine intake air flow rate, a value detected by the air flow meter, the position of a throttle valve detected by a throttle position sensor, and a value detected by an engine speed sensor are input. The calculating device calculates a time constant of a delay of response of the air flow rate into the engine, and an air flow rate passing through the throttle valve to compensate for the delay of response, and drives the throttle valve such that the flow rate of air passing through the throttle valve agrees with the calculated value.

    摘要： The invention relates to an intake air flow sensor for internal combustion engines comprising a sensor main body (12) and a connection unit main body (14), the former consisting of a main passage (15) for passing intake air and a bypass passage (16) for bypassing part of the air flowing through the main passage (15) and joining it again to the air of the main passage (15). An intake air flow meter (26) is disposed in the bypass passage (16) to measure the intake air quantity. The bypass passage (16) has an outlet opening (20) which opens to the main passage (15). A ring (22) is fitted into the main passage (15) of the sensor main body (12) in such a manner as to close part of the outlet opening (20) of the bypass passage (16). An insulator (30) is clamped by the ring (22) and the connection unit main body (14). According to this construction, the area of the opening (20) of the bypass passage (16) to the main passage (15) is not changed due to the deformation of the insulator interposed between the sensor main body (12) and the connection main body (14) which are fixed together by bolts.

    摘要： An exhaust emission control device for Diesel engines comprising a trap (14) disposed in an exhaust pipe (12) connected to an exhaust manifold and a trap-heating burner (16) disposed outside the exhaust pipe (12), whereby a combustion gas from the burner (16) is led to the outer peripheral portion of the trap (14) to heat the same.
    According to the exhaust emission control device for Diesel engines of the present invention, the stable oxidation of particulates collected on the trap (14) in the exhaust pipe is achieved independently of the flow rate of the exhaust gas, the exhaust pressure and the amount of O z in the exhaust gas.
