Commercial vehicle (CV) engine hardware has evolved significantly over the last three decades in order to respond to the global focus on emissions reduction and fuel economy requirements. Heavy Duty Engine Oils (HDEO) must evolve and anticipate these trends to meet current and future performance demands.

Top tier oils drive profitable fleet management

The new GM dexosTM1 specification demands dramatically enhanced performance in 3 important areas: of wear, pre-ignition and fuel economy. Innovation is key to perform at the ‘next level’ as GM dexosTM1 pushes the frontiers of lubricant science.

From the latest electric vehicle technology such as direct-cooled eMotors and multi-speed eAxles, to emerging technology such as immersion-cooled battery modules, all can benefit from targeted lubricant additive solutions. Modern lubricants work exceptionally hard to deliver the right balance of cooling, protection, efficiency, and reliability for a myriad of vehicle systems. The additives in these lubricants can dramatically enhance performance and be pivotal in bringing new hardware to market. Successful engineering is all about balance and Afton’s value lies in its ability to unlock new technology through the right blend of additives as well as understanding the importance of close and early partnerships between those providing the specialist lubricant technology and those developing the hardware. This article explores how Afton Chemical offers a guiding hand to help each partner find - and keep - their balance.

Recent simulations have explored the potential benefits of three areas of emerging eAxle technology: direct oil-cooling of eMotors, multi-speed transmissions and battery immersion cooling. eMotors generate a formidable amount of heat, so direct oil-cooling is increasingly seen as a way to optimize performance. While the market continues to eVolve, electric vehicle lubrication is also coming of age – bringing with it the power of cool. This article explores the latest research from Ricardo and Afton Chemical, highlighting the benefits of effective cooling for eAxles, multi-speed transmissions and beyond.
