OPERATION MAINTAINING OF AUTOMOBILE FORCED DIESEL ENGINES WITH ENSURING OF FUNCTIONAL CONDITION OF THE LUBRICATION SYSTEM IN EXPLOITATION

The efficiency improvement of car operation is the main task of the system for maintenance and repair of diesel engines, in particular by reducing the cost of current and major repairs of engines, which are the most expensive unit (up to 25%). The engine work reliability with the ensuring the minimization of friction between the mating parts and the removal of excess heat from the most loaded elements, the performance of oil and its characteristics at an established level during operation of vehicles. The regularities of the volume effect of oil in the crankcase of diesel engines on the intensity of changes in the technical condition of the engine and oil aging during the operation are investigated. The analytical dependences of the intensity of engine oil aging, changes in the technical condition of the cylinder-piston group and the crankshaft bearings of the engine on the volume of oil in the crankcase of forced engines are substantiated. The process of preventing the lubrication system has been improved by optimizing the volume of oil topped-up to compensate for its loss and leakage.
