A Reliable Single Cylinder Engine Test for Evaluation of Today's Heavy-Duty Diesel Oils for Oil Consumption and Piston Deposits 881582

This paper reports a lubricant study conducted on a Caterpillar 1Y540 single-cylinder engine test equipped with a 34068 truck production piston. The sequence test, run under well controlled conditions for a large number of CE and CD+ diesel oils, shows a good discrimination of the lubricant for oil consumption and piston deposits and similar to that given by new North American multicylinder engine tests utilizing LTL pistons. Owing to its excellent reliability, adequate severity, and availability of hardware parts, this engine test provides a suitable alternative for replacement of the Caterpillar 1G2 and EMA SCOTE-1.
