The successful development of a superior cylinder lubricant depends upon the measurement of wear in a modern crosshead engine operating under actual service conditions. A sensitive and continuous method for accurately determining the piston ring and liner wear has been developed. The monitoring system consists of four types of sensors and a scrape-down oil collection device installed on two of the cylinder liners. The sensors detect piston ring/liner scuffing and the presence of stuck or broken piston rings. Liner wear sensors provide a sensitive continuous record of cylinder liner wear while metal analysis of the scrape-down oil provides a relative measure of the total wear occurring on both the piston rings and the cylinder liner. The measurements are obtained without dismantling the engine and indicate the antiwear performance of a cylinder oil within a relatively short period of time.
