The Proper Fuel Filters for Modern Diesel Fuel

There are now more diesel vehicles on the roads. This is due mainly to the better hauling ability of diesel engines. Diesel engines are better at hauling heavy loads because of the way they operate. Although the fuel and engine are not capable of high revolutions, what it lacks in speed, it makes up in brawn. Diesel engines have higher torque than gasoline-fueled engines. The higher torque allows for heavier loads.

The Need for Diesel Powered Engines

Heavy loading does not mean that the vehicle is carrying a lot of items. It can also result in better performance for off-road situations. Most off-road vehicles are powered by diesel engines because the lack of traction on muddy trails or in crossing a stream requires more pulling power. Due to this capability, most trucks, semi-trailers, SUVs, and off-road vehicles are powered by diesel engines. There is also the odd high-performance Daimler-Benz sports cars are also run on diesel.

Like all vehicles, a diesel engine needs a filter to clean up the fuel before it is fed to the engine. All sorts of sediment and impurities get into the fuel tank, including water. Fuel filters are cylindrical with a bowl at the bottom. This is where the water is collected. Due to the difference in specific densities, water does not mix with the fuel. Instead, it separates and collects at the bottom of the container. When cleaning the filter, the water is drained before removing the filter element.

Efficient Water Filters

When it comes to water, there are some other considerations. First off, today’s diesel fuel mixes with water. Today, diesel fuel has a low-sulphur content, and this suspends the water with the fuel. Water emulsifies and no longer separates from the fuel. This requires a filter like that available from, which can strip the water out of the fuel before feeding it into the engine. This results in better performance from your vehicle.
