Abstract: A fuel control apparatus is mounted directly on the intake tube of an internal combustion engine by means of a heat dissipating fin having a fuel passage extending therethrough. The apparatus includes a control device for controlling the operation of a fuel injection valve in accordance with various parameters such as the quantity of incoming air to the engine and the temperature of the engine. The heat generated by the control device is dissipated to the fin and the fuel passing through the passage and heat insulating material is interposed between the fin and the intake tube. The fuel passage extending through the fin may carry fuel to or from the fuel pressure controller and the fuel tank or may carry fuel from the fuel pressure controller to the fuel injection valve.
