Еще 2 отличия нового двигателя BMW S63TU:
- Innovative solenoid valve injectors in the new BMW M5 engine use multiple injections to achieve an extremely precise mixture preparation.
-
VALVETRONIC
This is the biggest difference. As BMW puts it:
"Throughout each of its four previous generations, the heart of the BMW M5 has been its high-revving, high output-per-liter engine fed by individual throttle plates.
The new M5 engine introduces VALVETRONIC variable valve control system for the first time on a BMW M engine – effectively providing 16 individual throttles.
VALVETRONIC is BMW’s patented fully variable valve control system that eliminates the need for conventional throttles. Engine power is instead controlled directly by varying the amount of lift of the intake valves. Throttle losses in the gas cycle are minimized with this system, which has a positive impact on both the efficiency and torque. VALVETRONIC has also sharpened the responsiveness of this engine compared to the V10 engine it replaces."
