Abstract

Problem
An object of the present invention is to realize a compact formation of an intake system by unitizing a throttle position sensor and a fuel injection controlling elements and mounting unitized one on a throttle body in a compact manner.
Solution
In an intake system provided with a throttle body 11 having an intake path 12 communicating with an intake port of an engine E, with a throttle valve 20 for controlling an intake quantity of the engine by means of the intake path 12, and with a fuel injection valve 9 for injecting fuel and supplying to the engine E, the throttle body 11 is mounted with an electronic controlling unit U integrated with a throttle position sensor Sth for detecting an opening degree of the throttle valve 20 and with a fuel injection controlling elements 81 and 82 for controlling fuel injection quantity of the fuel injection valve 9 on the basis of, at least, an output signal of the throttle position sensor Sth.
