Title:
SENSOR MODULE UNIT AND THROTTLE DEVICE WITH THE SAME
Document Type and Number:
WIPO Patent Application WO/2004/074661
Kind Code:
A1
Abstract:
A sensor installation structure that greatly facilitates the installation of sensors arranged on the suction tube side of an engine and enables each of the sensors to be positioned at an accurate measurement position. A sensor module unit has sensors integrally attached to it, where the sensors are required for fuel feed control and suction air flow rate control in a internal combustion engine. The sensor module unit is provided with a suction air temperature sensor-holding portion at which a suction air temperature sensor is installed; at least either a throttle position sensor-holding portion at which a position sensor for detecting the degree of opening of a throttle valve in a suction air throttle device is installed or a suction air pressure sensor-holding portion at which a suction air pressure sensor is installed; the suction air temperature-holding portion; and a unit body for integrally receiving at least either the throttle position sensor-holding portion or the suction air pressure sensor-holding portion and for positioning the at least either of the two at a predetermined position in the unit. With the structure above, when the unit body is installed in the vicinity of a throttle shaft of the suction air throttle device, each of the sensors is positioned at a predetermined measurement position in the throttle device.
