Lubrication Challenges for Fuel Agnostic Engines

Dr. George Zhang | Vice President, R&D, Valvoline Global Operations

Significant progresses have been made in improving the energy efficiency of internal combustion engine (ICE) vehicles by advancing engine configurations, tooling and manufacturing, choice of materials, and fluid formulation designs, among other things.  The energy transition toward more sustainable sources is driving OEMs to adapt engine platforms that traditionally are fine-tuned with gasoline and/or diesel to work with various types of greener fuels, such as natural gas, hydrogen, and even ammonia. Although tribological fundamentals in lubricating the moving parts within the engines stay the same, there are challenges in handling the different chemical and physical characteristics of the fuels and their combustion mechanisms. We will give a brief overview on the lubricant formulation designs in dealing with these challenges.
