Schaeffler Deutschland | Presse | Schaeffler Continues the Success Story of UniAir Technology that has Proven itself Many Million Times (at https://www.schaeffler.de/content.sc...sp?id=77757056 )
The latest generation of UniAir technology is also demonstrating its potential. In this specific case - a newly-developed four-cylinder gasoline engine series - the UniAir system is combined for the first time with two hydraulic camshaft phasing units in accordance with customer-specific requirements. The additional degree of freedom offered by the system with its optimized mass design means that the engine can operate in an even broader spectrum of the data map with optimum efficiency. This means, for example, that the engine can be switched off in start-stop operation and can be started again at lightening speed keeping vibrations in both instances to a minimum. Another advantage of the technology is the fast and precise control of the valves to match the relevant cycle. This allows an instant increase in torque without impairing the efficiency of the engine due to the significant retardation of the ignition timing.
Ron Lee, Powertrain Director in the Development department at Jaguar explains that “with the Jaguar Land Rover Ingenium gasoline engine, we have successfully completed the first stage on the way back to producing our engines in-house. The close collaboration with Schaeffler has made a significant contribution here. The engine scores points with its outstanding driving behavior, excellent performance, and reduced fuel consumption”.
