Diesel Soaps Cause Engine Problems

摘要

In a May 2013 report, "Case Study-Impact of Poor Diesel Fuel Quality on an Urban Fleet," Cummins Filtration investigated problems with diesel engines in a New York City bus fleet. Complaints ranged from an excessive number of turbocharger fault codes to smoke at start-up to fuel-injector failures. The investigation uncovered excessive soot deposits in the turbocharger, resulting from over-fueling, which was determined to be the result of fuel injectors sticking because of deposits that were "rich" in the metals of sodium and calcium.
