Today’s diesel equipment requires higher fuel cleanliness to meet the demands of precision-designed fuel system pumps and injectors.
The Importance of Fuel Filtration
However, keeping diesel clean is more complex because of higher concentrations of water emulsions in fuel and organic contaminants that could foul the system.
Fortunately, Donaldson says, advancements in fuel filtration help to meet growing fuel cleanliness requirements of modern diesel engines for increased performance. Here are the five quick facts about fuel quality and today’s technology that the company has listed:
1 Smallest Contaminants Could Be Crippling
The high-pressure common rail (HPCR) fuel systems used in low-emission diesel engines are much more susceptible to damage from contaminants 20 times smaller than the diameter of human hair. For OEMs, this means more stringent requirements for fuel filtration. Today, the industry is measuring high-efficiency closer to 99.9 per cent for particles in the four-micron range. A fraction of a percentage point could make the difference on whether a filtration system could achieve the fuel cleanliness requirements for the HPCR components…..
