Heavy Machinery Fuel Systems
Heavy machinery, with their powerful blend of diesel engines and hydraulic systems make construction and farming jobs much simpler. The fuel systems of these machines are similar to those of other vehicles powered by internal combustion engines and include components for fuel storage, delivery and filtration.Fuel Storage
The fuel tank is what stores the diesel the engine needs until it needs it. While it is not a complex piece of equipment, the tank is important. Fuel tanks usually have plates inside them that prevent fuel from sloshing around during movement. In addition they are often designed to prevent inlet fuel from moving immediately to the outlet port. Fuel tanks can develop leaks due to age or damage, especially since heavy machinery is often operated in tough conditions. Small leaks in a fuel tank can lead to large cumulative losses of fuel. Since this can lead to financial losses, it is advisable to repair such leaks as soon as possible. In some cases the best solution is to replace a damaged fuel tank with a new one, always ensuring that the new tank's size is compatible with the space available. Lastly, all fuel tanks have a filler cap. Ideally the cap includes a pressure relief valve and a vent valve.Delivery to the Engine
A fuel pump moves diesel from the fuel tank to the engine. Pumps may be engine-driven or be part of the injection pump. Hoses are another important part of the fuel delivery system as it is through these that the pump delivers fuel to the engine. The final step is managed by the injector system, which provides precise amounts of diesel to the engine for combustion.Fuel Filters
Dirt and debris can enter diesel at different points during its delivery to the engine. Fuel filters help remove these impurities and provide clean diesel to the engine, essential to prevent damage to injector components. Some machines use two fuel filters, a primary and a secondary one. While fuel filters should remove water as well, some engines may have a separate water separator.
