Enhancing the performance of forced-induction diesel engines by improving oil volume management in the lubrication system

Abstract

The relevance of this research is based on the need to find additional ways to improve the efficiency of using forced-induction engines in vehicles and to reduce the ongoing costs of their maintenance. The research aims to evaluate the general principles and patterns of how oil level in the engine affects oil aging and changes in the technical condition of the diesel engine. The study included an experimental assessment of how motor oil parameters change during the operation of a car engine. The results provided data that shows how various parameters, which characterize the performance of a forced-induction automotive diesel engine, depend on the oil fill capacity. The study also determined how the cost of improving the performance of a forced-induction automotive diesel engine relates to the frequency of oil changes during its operation. Furthermore, the paper describes the operating principle and proposes a design for a regulator of the oil level in the engine crankcase. The findings indicate a need to reconsider the current practice of changing the oil in the crankcase of automotive diesel engines every 2000 km. This is because, under this schedule, the specific operating costs of the engine are high and economically inefficient. The practical significance of the results lies in the ability to change the oil volume in the lubrication system during vehicle maintenance, as well as when a major overhaul or forced induction of diesel engines is required.
