THE USE OF AMMONIA AS A NEUTRALIZING AGENT IN MARINE DIESELS OPERATING ON SOUR FUEL,
Abstract
When diesel engines operate on sour diesel fuel, there is increased cylinder and piston wear and an increase in carbon and lacquer deposit. A basic method of overcoming the harmful effects of sulfur contained in diesel fuel is to apply additives to the fuel and oil. Test runs were made on cylinder and piston ring wear, as well as the weight of carbon deposits on the bottoms of the pistons and on the cylinder heads. It was established that aotal wear on the outer cylindrical surface of all rings was 1.2-1.8 times less for cylinders operating with an ammonia additive. The weight of carbon deposits on the bottoms of the pistons operating on ammonia was 10-20% less than without ammonia. In this case, the carbon deposits on parts of cylinders operating on ammonia were not as dense and constituted a porous, flaky mass, while carbon deposits on parts of cylinders which did not receive an injection of ammonia were dense and fine-grained.
