Understanding and Mitigating Oil Consumption in Heavy-Duty Engines: Key Factors and Solutions
Vikrant Rayate
Abstract
Oil consumption in heavy-duty engines is one of the main concerns in both automotive and industrial sectors, impacting both operational costs and environmental sustainability. With growing demands for improved fuel economy and eco-friendliness, much focus has rested on research aimed at minimizing oil consumption through components like the piston, pin, and bushing of the engine. These are some of the major components of an engine and come into direct contact with the engine oil, therefore influencing the wear and friction characteristics responsible for oil loss over a period of time. This paper analyzes in great detail the dynamics of the pin, piston, and bushing in heavy-duty engines and how these factors contribute to oil consumption. The following describes the various materials used to make the parts, the influence of design and lubrication systems on oil consumption, and wear mechanisms leading to increased oil consumption. Thereafter, it will be possible to find ways for optimizing their design and functionality with the aim of reducing oil consumption without deterioration in or loss of performance.
It is a wide-based study that considers factors such as material properties, operational aspects (load, speed, and temperature), and newer developments in lubrication techniques. The review also covers all the latest developments in engines related to oil reduction, covering areas such as precision-engineered pistons, low friction bushings, and latest lubricants for wear and oil consumption minimization. This paper tries to reveal the mechanism that drives the oil consumption of heavy-duty engines through experimental data, case studies, and theoretical analysis, and further propose possible ways to mitigate this issue.
This research is of relevance to engine manufacturers, fleet operators, and policymakers involved in the effort to minimize the environmental impact of transport and industrial engines. The results presented here tend to contribute not only to more environmentally friendly engine design but also to reduce operational costs, prolong the life of an engine, and generally improve vehicle efficiency. In conclusion, this paper is supporting the adoption of advanced materials, innovative designs, and effective lubrication strategies as important steps toward minimum oil consumption and further development of next-generation heavy-duty engines.
