Hybrid Theory

Although hybrid Internal Combustion Engines (ICEs) are developing fast, with a focus on efficiency and emissions reduction, the hardware still feels like familiar territory for many engineers and oil companies. However, the demands on hybrid ICEs can often deviate from conventional ICE vehicles, with significant implications for the protection and functions provided by the engine oil. It is important to fully understand the connection between severe hybrid ICE operation and the corresponding engine-oil performance. Only then can risks be mitigated effectively over the engine and lubricant's lifetime.

The article below explores how ICE operating conditions can vary in hybrid vehicles versus conventional cars and how this impacts engine oil requirements. A new universal methodology can help to identify specific challenges.
