Abstract
Abstract A fuel control device (16) can be mounted directly on the intake tube (1) of an internal combustion engine (7) by means of a heat dissipating fin (17) having a coolant passage (21) extending therethrough. The control device controls operation of a fuel injection valve (3) in accordance with various parameters such as the quantity of incoming air to the engine and the temperature of the engine. Heat generated by the control device is dissipated to the fin (17) and fuel is preferably passed as coolant through the passage (21). Heat insulating material (20) may be interposed between the fin (17) and-the intake tube (1). The passage (21) may carry fuel to or from a fuel pressure controller (11) and fuel tank (15) or may carry fuel from the fuel pressure controller (11) to the fuel injection valve (3).
