CASTROL’S INNOVATION BUSINESS NEXCEL PREDICTS CO2 REDUCTION AT A €/G COST SIGNIFICANTLY LESS THAN MILD HYBRIDISATION
Testing of the latest Nexcel active engine oil management system across three different engine types demonstrated the system’s potential to reduce CO2 emissions by 2 g/km. The reduction is delivered by ensuring a precise oil-engine match, helping the oil to warm up more quickly and boosting the oil’s active components in-between oil changes.
Nexcel’s active engine oil management system is an easy to change unit containing engine oil, a filter and an electronic control unit. The plug and play oil cell is designed for flexible installation anywhere in a vehicle’s engine bay via a docking station.
Nexcel is an automotive start-up that combines Castrol’s knowledge of lubricants technology with BP’s focus on growing businesses which support customers in reducing their emissions. Nexcel provides an effective solution for engine designers aiming to reduce CO2 emissions in both hybrids and pure internal combustion vehicles. The anticipated cost for each gram of CO2 saved with Nexcel is around €42(1), similar to the cost per gram of CO2 for a micro hybrid (stop-start plus regenerative braking) and approximately half the cost per gram for one of the most popular new technology strategies, a mild hybrid system(2).

“Using data from the European Commission’s 2017 Impact Assessment of Upcoming CO2 Regulations,(2) we have established that Nexcel is one of the most affordable routes to CO2 reduction which will help passenger cars meet the Commission’s demanding 2021 European fleet average target of 95 grams of CO2 per kilometre,” states Nexcel business development director, Ben Russell.
Emissions improvements have been recorded across several popular engine types, including conventional 2.0 litre gasoline, downsized 2.0 litre gasoline with GDi, and 2.0 litre diesel. The most substantial improvement was seen on the downsized, turbocharged gasoline engine, an architecture that is predicted to be one of the most important as the industry moves to smaller, more highly-stressed spark-ignition engines with or without electrification.
Being able to plan for a precise oil-engine match throughout the life of an engine opens up new possibilities for engine designers to reduce CO2. For instance by ensuring that an engine uses the same lubricant throughout its life, designers may be able to use smaller more efficient bearings and higher loads, without having to compromise how far they can go. With Nexcel an electronic handshake automatically confirms the correct oil and filter every time the oil is changed.
