CRANKCASE LUBRICANTS FOR FOUR-CYCLE RAILROAD AND MARINE DIESEL ENGINES

The diesel engines used as power plants for US designed diesel electric locomotives are among the highest output rating in use for any application. In 1965, highly dispersant lubricating oils were first introduced to the railroad industry. Since that time, the engine output rating of the four-cycle railroad diesel engine has increased from 14.6 kg/sq cm (207 psi) BMEP to 19.9 kg/sq cm (282 psi), principal components have been changed in design and there has developed a world distillate fuel shortage. To meet these changes, engine lubricants with improved performance features were required, were developed and are now available. The lubrication of the 7FDL four-cycle diesel engine manufactured by the author's company over this time span is discussed form the viewpoints of: fundamental crankcase lubricant performance requirements, lubricant performance improvements and used crankcase oil condition monitoring. Particular emphasis is given to corrosive wear control and deposit control, both of which can be adversely affected by changing distillate fuel properties.
