Abstract

An internal combustion engine such as a multi-cylinder in-line engine having on one side of the cylinder head an air induction system and on the opposite side an exhaust system, each extend generally in the direction of the length of the engine. Each of said systems extending above the level of a cylinder head of the engine and a fuel rail is provided extending in the direction of the length of the engine and mounted on the cylinder head to be located between the air induction system and the exhaust system. The fuel rail overlies and is in fuel transfer communication with respective fuel injector units mounted in the head of each cylinder of the engine. Preferably, the fuel rail is configured so as to provide sufficient clearance on the exhaust side thereof to enable spark plugs to be appropriately arranged within the cylinder head on the exhaust side thereof. The fuel injector units may be of the type wherein the fuel is entrained in a compressed gas for delivery to the engine and the fuel rail includes both a passage for the conveyance of fuel and a further passage for the conveyance of the gas, normally air.
