Diesel Fuel System Layout

The fuel oil was a primary energy source used consistently throughout the year.

Diesel fuel system layout. Description of a modern diesel fuel system as a standby energy source. 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. In early fuel oil system designs boilers were the primary user of the fuel. No electrical spark is used as in a gasoline engine the fuel system consists of the following components.

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. Introduction to fuel supply system for ci engines. 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.

Fuel supply system in diesel engine. When designing fuel oil systems remember the following. Fuel system design checklist. The modern diesel fuel or fuel oil systems are used differently than systems designed a decade or more ago.

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. 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. 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.
