摘要： PURPOSE:To prevent a turbulent flow from being generated on an internal wall surface owing to a contraction flow at an opening part and to improve the detection performance by forming the internal surface of a cylindrical housing in a venturi shape. CONSTITUTION:The cylindrical housing 1 arranged in a fluid passage is shaped in the venturi shape so that the internal diameter of its inner peripheral surface is set smallest nearby the extension part of a hot wire PH extended between hot wire supports 2. Then an air temperature sensor RC is mounted in this housing 1. The flow nearby the internal wall surface of the housing 1 is does not separate from the wall surface because the internal wall surface is nearly equal to flow lines of fluid due to the contraction flow, and there is no turbulent flow generated nearby the wall surface. Consequently, the fluid is prevented from varying in flow velocity and the detection sensitivity is improved.

摘要： PURPOSE:To maintain the satisfactory emission performance of an engine, by providing such an arrangement that upon detection of an engine rotational speed which is lowered below a set rotational speed near the idling rotational speed, the amount of fuel is increased until a predetermined time period elapses from the time point of the lowering of the engine rotational speed. CONSTITUTION:When the temperature of intake-air is low during running of the engine, a bimetal type shut-off valve 19 is closed to introduce the vacuum of intake-air downstream of a throttle valve 6 into a vacuum chamber 16 in a vacuum switch 11 through a passage 18, and therefore, a switch section 14 is turned on. In addition to this condition, if a choke switch 26, a water temperature switch 27 which is turned on when the temperature of cooling water is below a predetermined value, an engine stop detector 28 and a cooler switch 29 are all turned off, but if a neutral switch 30 is turned on, a transistor 12 is turned on when an engine rotational speed detecting circuit 21 detects the engine rotational speed which has been lowered below a set rotational speed near the idling rotational speed. Accordingly, a richer valve 10 is opened for a set time by a timer 22 to aim at increasing the amount of fuel.
