The article presents theoretical and experimental studies on the operation of the lubrica-tion system at a technological breaking-in of engines. Lubrication sys¬tem a large extent determines the reliable and efficient operation of the engines. The oil pump provides decrease friction losses, heat removal by details and removal the wear products out con-jugations. Engine oil reports not only a protective medium for parts, but also of source of information about the technical condition of the engines. The calculated relationships between the working capacity indicators of the lubrication system are given. Correlation interrelationship between kinematic viscosity and density of motor oils nomenclature is established. Influence of dynamic viscosity of oil on pressure in lubricating medium and thickness of oil layer in bearing units is shown. Practical recommendations for control and maintenance of the lubrication system are given.
