Car Engines Lubrication

3 days LUB/LUBMA-E
  • Engineers and technical staff involved in the development, recommendation, manufacturing, sales, technical service of engine lubricants.
  • Engineers and technical staff involved in the study, testing, use, development, tuning of Diesel and gasoline engines.
  • To bring the necessary knowledge for understanding the role and the action mechanisms of the lubricant in different lubricated parts of an internal combustion engine.
  • To allow a better understanding of the complexity of the system of development of engine lubricants.
  • To give the general principles of lubricants development, physico-chemical and mechanical tests used to validate them.
  • To learn how to read the maintenance booklet of a vehicle.
  • To elucidate what is behind the various SAE, API, ILSAC, ACEA classifications and specifications.
Learning Objectives
  • To perform a complete review of the lubrication circuit of internal combustion engines and of the functional properties required to insure the proper lubrication of the different organs.
  • To detail the chemical composition of the products.
  • To give notions on the codes of practice imposed by the standardization and certification organizations.
  • To explain the formulation principles of engine lubricants, the performance characterization testing methods.
  • To give the principles of follow-up of engine lubricant in service.
  • To maximize the benefits of this training, it is strongly recommended to initially follow the training entitled “Introduction to engines”.
Ways and means
  • Interactive exercises with the teacher to determine the lubricant to use according to the type of vehicle, the climate and operating conditions.
  • Interactive exercises of questions-answers between the participants using sets of play cards to synthetize the essential points of the lectures.
