Study on the Properties of Lubricating Oil for Hydrogen Internal Combustion Engines
Carbon reduction,energy conservation,and extending oil change intervals are the three major driving forces be-hind continuous innovations in engine technology today.Internal combustion engine oil technology is constantly evolving to-wards lower sulfur,phosphorus,and ash content,as well as lower viscosity and improved energy efficiency.Hydrogen fuel is the best choice for diversifying energy sources in the automotive industry and reducing vehicle exhaust emissions,serving as a significant solution to the current serious energy crisis and environmental pollution issues.Hydrogen internal combus-tion engine lubricating oil has its unique combustion characteristics.This paper analyzes the challenges faced by lubricating oil for hydrogen internal combustion engines and proposes solutions.Additionally,the oil samples of a brand K05H engine were collected and analyzed after 200 hours of bench test.The results show that the various indicators of the oil remained stable and normal during the tests,and the oil showed satisfactory performance.
