Fully variable valve drive.
Without requiring a throttle butterfly, fully variable valve drive controls engine output by infinite adjustment of valve stroke and intake valve opening times. This loss-free load management reduces fuel consumption, cuts back emissions, and ensures better engine response with an enhanced standard of motoring refinement.
Twin-scroll turbocharger.
On the twin-scroll turbocharger the ducts of each set of two cylinders are separated from one another in the exhaust gas manifold and the turbocharger. This serves to build up a charge effect from just about 1,400 rpm, with torque being generated just as quickly as on a compressor engine.
Direct gasoline injection.
High-pressure gasoline injection (120 bar), together with advanced turbocharger technology, is the main reason of the high level of specific output, low fuel consumption and the exemplary emission management ensured by the turbocharged engine.
Fully controlled oil pump.
On-demand oil supply delivers only as much oil as is actually required. Depending on operating conditions, the volume flow-controlled oil pump requires up to 1.25 kW less drive energy and reduces fuel consumption by up to 1 per cent.
On-demand water pump.
Driven by a friction gear, the water pump is not activated until the engine has reached its normal operating temperature, thus enabling the engine to warm up more quickly. This serves both to reduce fuel consumption and improve emissions at the same time.
Aluminium crankcase in bedplate design.
Offering best-in-class stiffness, excellent noise management, and the integration of numerous functions and ancillary units, the aluminium crankcase is quite unique in every respect.
