How to best protect your engine



The Fleetguard product line.

We know that fuel contamination can cause fuel system components to fail, leading to costly repairs and downtime.

Understanding the impact of fuel contamination on your vehicle’s engine and limiting their negative impact can significantly increase vehicle life expectancy and reliability.

There are a variety of different types of contaminants that exist in fuel, namely organic and inorganic contaminants.

The increase in contamination can be cumulative through all of the processes involved in moving fuel along the path from output to engine. Each process can add more and more contamination to the originally clean fuel, rendering it unusable by the time it reaches sensitive fuel system components.

Organic contaminants lead to premature filter clogging or development of corrosion leading to hard particle damage and introduction of inorganic particles to fuel production, fuel transport vessels, storage tanks , transfer equipment, pumping stations and fuel tanks of vehicles, etc., controlling the impact of both types of contaminants are always present.

If the fuel is relatively clean, a quality, well-selected filter can help “polish” the fuel, to meet the cleanliness specifications required by fuel injection equipment manufacturers. However, it’s not that simple when it comes to cleaning dirty fuel with just one filter. Even with very efficient filters, the dirtier the fuel, the more particles will pass through the filter.

For example, if a filter is 99.5% efficient (for a given micron range), that still means that 0.5% of the contamination in the pre-filtered fuel will pass. Consider that a relatively clean fuel contains 1000 particles of a given size for each milliliter of fuel. At 99.5% efficiency, the filter would pass only five particles. But let’s say the fuel is relatively dirty, with 100,000 particles of a given size in the same volume of fluid. This same filter would then allow 500 particles to pass. That’s 100 times the number of contaminants that accelerate fuel component wear despite filter efficiency at 99.5%.

It goes without saying that it is important to control the filtration of the fuel at the many points of distribution, handling and storage in order to closely control the level of contamination. Additionally, fuel pre-cleaning may be required to further purify and clean the fuel to optimize engine efficiency. Products such as Fleetguard Diesel Pro, Fleetguard Fuel Pro and Fleetguard Industrial Pro filters are purpose-built and offer a host of on-board pre-filtering features to help reduce the load on vehicle fuel filters when dealing with dirty fuel.

Fleetguard Pro Series filters aim to deliver high efficiency media, with technological advances in media design that allow for high dirt holding capacity and excellent water removal capabilities throughout. throughout the life of the element. These advancements help extend the life of fuel system equipment and reduce filter change intervals, reducing the total cost of engine ownership. According to Cummins Filtration, they easily adapt to any vehicle fuel system.

Managing fuel cleanliness is about understanding the life cycle of fuel and identifying problematic movement points to introduce effective supplemental filtration to deal with practices that are less than satisfactory or even passable.

Cummins Filtration recently introduced an effective and easy field test kit that can help determine if diesel fuel meets cleanliness requirements. Companies such as Cummins Filtration, which invest in equipment and technology that studies fuel cleanliness and provides system improvement solutions, will prove to be the most consistent and reliable products on the market. Fleetguard products know how to best control and protect your engine.
