Role of Sulfur Oxides in Wear and Deposit Formation in Army Diesel Engines
Abstract
In some locations outside the continental United States, U.S. Military ground mobility equipment uses fuel with an increased sulfur content. Fuel sulfur has been identified as a primary contributor to diesel engine wear indicates that sulfuric acid mist formed within the combustion chamber is responsible for corrosive attack of the cylinder bore and piston ring areas. Deposit formation has been more of a mystery in that the literature tends to support the theory that reaction of organically bound sulfur with the fuel and lubricant is the principal cause. Studies presented here suggest that sulfur dioxide (SO2) formed in the combustion of fuel-bound sulfur is the primary cause of higher cylinder bore/ring wear and deposit formation in diesel engines.
