Improvements on Diesel Combustion of Low Grade Marine Fuels

Abstract

This paper reports on the improvements in diesel combustion of low grade marine fuels. The presented data are on the effects of characteristics of the low grade marine fuels on the diesel combustion, on soot reduction by barium compound additives and in the burning of emulsified marine fuels, on the combustion and wear of two cracked type high viscous marine fuels; a fluid catalytic cracked bottom based oil and a visbreaker bottom based oil, in the experimental apparatuses and in a marine low speed diesel engine. The latter experimental results suggests that, in the burning of the fluid catalytic cracked bottom based oil, the silicon particles in the burnt gas are mixed in the sliding surface between cylinder liner and piston rings, the so called, it is abrasive wear, and the wear rates become large.
