Diesel Fuel System Layout

In early fuel oil system designs boilers were the primary user of the fuel.

Diesel fuel system layout.

Diesel engines rely on the air fuel mixing being done in the cylinder which means they need a fuel injection system. Flow diagram of fuel in diesel tractor cylinder injector fuel diesel tank fuel filter lift pump filter fuel injection pump. Fuel system design checklist. 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.

When designing fuel oil systems remember the following. 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. 1 fuel filter 2 fuel lift pump 3 fuel injection pump 4 atomisers and 5 high pressure pipe. The fuel oil was a primary energy source used consistently throughout the year.

The modern diesel fuel or fuel oil systems are used differently than systems designed a decade or more ago. 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. 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. Description of a modern diesel fuel system as a standby energy source.

When calculating pump suction lift assume the worst case scenario i e a nearly empty tank. The main components of the fuel system in diesel engine are. Fuel supply system in diesel engine. Provide foot valves to maintain pump prime anti siphon valves to prevent accidental leakage and fusible link shutoff valves for fire safety.
