METHODOLOGY FOR EVALUATING THE EFFICIENCY OF THE MEANS OF TUNING THE LUBRICATION SYSTEM OF AUTOMOTIVE DIESELS

The work carried out a comparative analysis of various means of functional tuning of the lubrication system of automotive diesel engines of the KAMAZ family, such as: A device for monitoring the continuity of the oil flow to the connecting rod bearings during operation, an electronic indicator of oil consumption through the crankshaft bearings, an oil pumping system that allows pumping oil before starting a diesel engine in cold time, Hydroaccumulator allowing to pump oil through the turbocharger when the engine is stopped, Level regulator automatically maintains the optimum oil level in the crankcase, Limiting machine automatically stops the operation of the diesel engine. Ensuring an increase in the reliability and durability of automotive diesel engines. A brief description is given and an economic comparison of these tuning means is made. The values of the unit costs are given, taking into account the growth of the engine resource for each tuning option. The unit costs differ insignificantly. Preference can be given to the oil level regulator and the limit switch. In terms of economic indicators, the limiting machine of the lubrication system can be recommended for practical use, among other options for the functional tuning of cars.
