Diesel Fuel System Layout

No electrical spark is used as in a gasoline engine the fuel system consists of the following components.

Diesel fuel system layout.

When designing fuel oil systems remember the following. The function of the diesel fuel system is to inject a precise amount of atomized and pressurized fuel into each engine cylinder at the proper time. Fuel system design checklist. Fuel supply system in diesel engine.

Description of a modern diesel fuel system as a standby energy source. The fuel supply system of a diesel engine can be called as the heart of the engine since the engine performance directly depends upon the proper functioning of this system which must supply meter inject and atomize the fuel. Provide foot valves to maintain pump prime anti siphon valves to prevent accidental leakage and fusible link shutoff valves for fire safety. Diesel engines rely on the air fuel mixing being done in the cylinder which means they need a fuel injection system.

The modern diesel fuel or fuel oil systems are used differently than systems designed a decade or more ago. 1 fuel filter 2 fuel lift pump 3 fuel injection pump 4 atomisers and 5 high pressure pipe. Combustion in a diesel engine occurs when this rush of fuel is mixed with hot compressed air. Introduction to fuel supply system for ci engines.

When calculating pump suction lift assume the worst case scenario i e a nearly empty tank. In early fuel oil system designs boilers were the primary user of the fuel. The fuel is injected directly into the combustion chamber which can be either a segmented combustion chamber known as indirect injection idi or an unsegmented combustion chamber known as direct injection di. The fuel oil was a primary energy source used consistently throughout the year.
