A Severe Single Cylinder Diesel Engine Test for European SHPD Oils 872033

This paper describes the development of a severe diesel engine test and its use as a tool for the evaluation of high performance lubricants. The test has been designed to screen oils prior to submission for expensive multi-cylinder evaluation and uses a tight top land piston.
The paper continues earlier work reported during 1985 and describes the influence of liner finish and other hardware effects on test repeatability. The resulting ABINGDON 1-J engine test has been used in the development of diesel oils superior in performance to CCMC D2.
Traditionally, European Super High Performance Diesel oils have been of 15W40 viscosity grade, but engine manufacturers are showing increasing interest in lower viscosities.
The ABINGDON 1-J test has been used to evaluate both 5W30 and 10W40 oils of Super High Performance Diesel quality. Performance of both mineral and synthetic basestocks are considered.
