Diesel Fuel System Layout

Description of a modern diesel fuel system as a standby energy source.

Diesel fuel system layout.

When designing fuel oil systems remember the following. The main components of the fuel system in diesel engine are. Diesel engines rely on the air fuel mixing being done in the cylinder which means they need a fuel injection system. No electrical spark is used as in a gasoline engine the fuel system consists of the following components.

Combustion in a diesel engine occurs when this rush of fuel is mixed with hot compressed air. In early fuel oil system designs boilers were the primary user of the fuel. 1 fuel filter 2 fuel lift pump 3 fuel injection pump 4 atomisers and 5 high pressure pipe. Provide foot valves to maintain pump prime anti siphon valves to prevent accidental leakage and fusible link shutoff valves for fire safety.

When calculating pump suction lift assume the worst case scenario i e a nearly empty tank. Fuel system design checklist. Flow diagram of fuel in diesel tractor cylinder injector fuel diesel tank fuel filter lift pump filter fuel injection pump. Fuel supply system in diesel engine.

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. Foreword this section of the application and installation guide generally describes diesel fuels and diesel fuel systems for cat engines listed on the cover of. 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.
