INTRODUCTION
The function of the diesel fuel system is to inject aprecise amount of atomized and pressurized fuel into each engine cylinder atthe proper time. Combustion in a diesel engine occurs when this rush of fuel ismixed with hot compressed air. (No electrical spark is used as in a gasolineengine.)
The fuel system consists of the followingcomponents.
FUEL TANKS
There are many different types and shapes of fuel tanks.Each size and shape is designed for a specific purpose. The fuel tank must becapable of storing enough fuel to operate the engine for a reasonable length oftime. The tank must be closed to prevent contamination by foreign objects. Itmust also be vented to allow air to enter, replacing any fuel demanded by theengine. Three other tank openings are required--one to fill, one to discharge,and one to drain.
FUEL LINES Pdf a mac os x.
There are three types of diesel fuel lines. Theseinclude heavyweight lines for the high pressures found between the injectionpump and the injectors, medium weight lines for the light or medium fuelpressures found between the fuel tank and injection pump, and lightweight lineswhere there is little or no pressure.
FUEL FILTERS
Diesel fuel must be filtered not once, but several timesin most systems. A typical system might have three stages of progressivefilters--a filter screen at the tank or transfer pump, a primary fuel filter,and a secondary fuel filter. In series filters, all the fuel goes through onefilter and then through the other. In parallel filters, part of the fuel goesthrough each filter.
For more information on fuel filters, see Diesel Fuel Filter Basics.
FUEL TRANSFER PUMPS
Simple fuel systems use gravity or air pressure to getfuel from the tank to the injection pump. On modern high speed diesel engines,a fuel transfer pump is normally used. This pump, driven by the engine,supplies fuel automatically to the diesel injection system. The pump often hasa hand primer lever for bleeding air from the system. Modern injection pumpsare almost all jerk pumps which use the plunger and cam method of fuelinjection.
FUEL INJECTION SYSTEMS
There are fourprimary systems for injecting fuel: https://nswzkv.over-blog.com/2020/12/pixel-film-studios-proemitter-download-free.html.
1. Individual pump and injector for each cylinder
2. Combined pump and injector for each cylinder (unitinjector type)
3. One pump serving injectors for several cylinders (distributortype) Badland: game of the year edition 1 0. Avid media composer v8 8 for mac free download.

FUEL INJECTORS
Diesel fuel injectors are arguably the most importantfuel system component. The job of the injectors is to deliver a precise amountof atomized and pressurized fuel into each cylinder. Highly atomized,pressurized fuel distributed evenly throughout the cylinder results inincreased power and fuel economy, decreased engine noise, and smootheroperation.
Modern dieselfuel injectors, such as those found in common rail fuel systems, usepiezoelectricity. Piezoelectric injectors are extremely precise and can handlethe very high pressures found in common rail applications.
DIESEL FUEL
The fuel used in modern high speed diesel engines isderived from the heavier residues of crude oil that are left over after themore volatile fuels such as gasoline are removed during the refining process.The most common grade of diesel fuel is 2-D, more commonly known as ultra lowsulfur diesel (ULSD).
For more information on diesel fuel, see UltraLow Sulfur Diesel Basics.

WATER
A common enemy of diesel fuel systems is water.Unfortunately, water is more common in diesel fuel than most people realize.Should water find its way into an injection system, it will rapidly oxidizeferrous metal (steel) components. Some of the most common failures attributedto water include:

- Sticky metering components in both the pump andinjector

CONCLUSION
Adiesel fuel system is a critical component of any diesel engine and its optimumoperation is essential for peak performance. E-ZOIL manufactures severaladditives formulated to address common issues encountered by the diesel fuelsystem. DIESEL AID, DIESEL AID + CETANE, ARTIC POWER, ARTIC FLO and CLEAN &LUBE increase fuel system lubricity preventing premature failure of fuel pumpsand injectors. Additionally, DIESEL AIDand DIESEL AID + CETANE totally disperse water, which also causes prematurefailure of fuel system components.
