Caterpillar fuel filters
Caterpillar fuel filters serve a vital function for modern vehicles that are sensitive to the quality of motor fuel. Unfiltered fuel may contain several types of contaminants, for example, pieces of paint and dirt that could get into the fuel tank during refueling, or rust caused by moisture in steel tanks. If these substances are not removed before the fuel enters the system, they will lead to rapid wear and damage to the Caterpillar fuel pump and Caterpillar injectors, due to the destructive effects of particles on important components used in modern injection systems. Caterpillar fuel filters also increase the engine's power, since the less pollutants present in the fuel, the more efficient the combustion.
Some Caterpillar filters, especially on diesel engines, have the shape of a cup for collecting water at the bottom. The water can then be drained by opening the valve at the bottom of the bowl. A lot of Caterpillar fuel filters contain a water sensor connected to the engine control unit or directly to the driver, transmitting information about reaching a certain level of water. It is particularly undesirable when the water is stretched over the fuel system of the diesel engine, because the system uses diesel fuel to lubricate the moving parts, and if water gets to elements that require constant lubrication, this leads to overheating and excessive wear.
