Fuel rail-cooled engine control system

An engine control system for a fuel injected internal combustion engine comprising:

• a main engine control module;
• a first remote engine control module comprising an injector driver, an ignition driver, a power driver and a plurality of sensor inputs, said main engine control module and said first remote engine control module arranged to collectively control a first ignition component and a first fuel injector;
• and
• a first fuel rail manifold adapted for connection to said first fuel injector for supplying said engine with fuel;
• said first remote engine control module being mounted to and thermally coupled with said first fuel rail manifold;
• whereby
• fuel flow through said first fuel rail manifold cools said first remote engine control module;
• and whereby
• said first remote engine control module is located near to said first ignition component and said first fuel injector.

A method for cooling an engine control unit of an fuel-injected internal combustion engine, said engine control unit including electronic circuitry for controlling an ignition system and a fuel injection system of said engine, the method comprising the steps of:

• providing a fuel rail manifold;
• fluidly coupling said fuel rail manifold to a fuel injector for supplying fuel to said engine;
• and
• locating at least a portion of said electronic circuitry so as to be in thermal contact with said fuel rail manifold, wherein said at least a portion of said electronic circuitry comprises an injector driver, an ignition driver, a power driver and a plurality of sensor inputs, whereby
• fuel flow through said fuel rail manifold cools said at least a portion of said electronic circuitry.
