Precision of modern engine fuel systems moves development focus on filtration technology farther up the distribution channel.
Having access to clean diesel fuel has always been an important way to ensure machine uptime and reduce costly repairs and warranty claims. But in today’s diesel engine world, clean fuel has taken on a whole new importance. Modern fuel injection system components are machined to tight tolerances— sometimes as close as 2 microns, roughly the size of a single E. coli bacterium — to help boost injection pressures. One system supplier advertises that its “ultra high pressure” diesel common rail system delivers peak pressures of up to 43,500 psi. And these pressures are expected to increase as engine manufacturers tweak the combustion process in order to reduce emissions....
