One of the most notable features of the N46 engine is its advanced valvetrain system. The engine is equipped with Double VANOS (Variable Nockenwellen Steuerung) technology, which allows for continuous adjustment of the intake and exhaust camshafts. This results in improved low-end torque, increased high-RPM power, and reduced emissions. The Valvetronic throttle system, also used in the N46 engine, provides a wide range of throttle response and helps to optimize fuel efficiency. | Interval | Task | Diagram Reference |
