Abstract
The CIMAC organisation introduced in 1987 a new Working Group to handle the subject of engine lubrication.
This paper presents the different steps and achievements of that group since its foundation.
This group issued general Recommendations on lubrication of medium speed diesel engines as well as for two stroke slow speed engines.
Now the members of this working group are completing the study of particular points of interest on lubrication following the diesel engine technology evolution and the industy related concern or problems.
The future work of this CIMAC working group will be presented and explained.
A. INTRODUCTION
Early 1987 CIMAC (Conseil International des Machines A Conbustion) recognized that lubrication of diesel engines was of a particular interest and decided that a working group had to be created to handle the subject of engine lubrication.
The first meeting of this working group took place in the secretariat of CIMAC (in Paris at that time) in 1987, attended by several experts from the worldwide diesel engine industry and those related to the lubrication of engines. Since then 28 meetings took place (see Fig. 1 - Attendance Chart), at the rate of typically two meetings per year.

The first task of that group was to decide the "Term of Reference" or the objective of the group as well as to elect a chairman and a secretary.
The very first chairman was Mr. Wesselo and during the first meeting the members set the first stones of this working group. A few meetings then followed to create the cohesion of this original group and define the action to take.
After an initial slow start and much debate, the group decided to take on the task of studying the various aspects of lubrication and publish documents for the benefit of the industry; these documents would be intended as references for engine users, owners, sea-going engineers, students, i.e. all those related to the engine industry and its lubricaticn. A commonly recognized "User Language" was considered to be necessary for the industry and these documents are thought helpful to achieve that.
The task of this group was divided in 3 steps, i.e. to study and issue guidelines/recommendations on:
1) lubrication of medium-speed 4-stroke engines running on Heavy Fuel Oil,
2) the lubrication of two-stroke slow-speed engines running on Heavy Fuel Oil,
3) the lubrication of high-speed 4-stroke engines running on Heavy Fuel Oil.
