Fuel control apparatus for an internal combustion engine
First Claim
1. A fuel control apparatus for an internal combustion engine having an air intake tube rigidly attached to said air intake tube providing fluid communication between an air cleaner and said engine and having disposed therein a throttle valve, comprising:
- an electrically controlled fuel injection valve;
a control device for controlling said fuel injection valve in accordance with various parameters of said engine, said control device including a radiating fin on one end surface of said control device for removing heat from heat-generating elements which drive said fuel injection valve; and
means for mounting said control device on said air intake tube to directly fix said control device on said intake tube between said air cleaner and said engine, so that said radiating fin is cooled by incoming air conveyed in said air intake tube.

Abstract
A fuel control apparatus for an internal combustion engine which has an air intake tube includes an electrically controlled fuel injection valve and a control device for controlling the valve in accordance with various parameters of the engine. The control device includes a radiating fin which is located on one end surface of the control device for removing heat which is generated by heat-generating elements which drive the valve. The control device is mounted on the air intake tube so that the radiating fin projects into the air intake tube. In this manner, the radiating fin is cooled by incoming air.
