Do you have a car without a throttle?

Yes, the BMW 760 has no throttle! In addition to the eye-catching exclusive direct injection technology, the new V 12 engine * * * enjoys many advanced technologies of the new V8 engine code-named N62 on the 7th Series a year ago. One of them is Valvetronic. This is a revolutionary concept of "breathing". BMW's patent ranks first in the world. Valvetronic canceled the traditional throttle valve and replaced it with variable valve lift to control engine power. Valvetronic mechanism is located above the intake valves of two cylinder banks. Each of the 48 valves on the engine is driven by the rotating finger rocker arm of the camshaft hub. On the intake side, there is an additional element located between the cam boss and the rocker arm, which is called the intermediate follower. The middle follower drives the rocker arm, and then drives the valves in turn. Its position is determined by the eccentric shaft of the servo motor. The driver controls the accelerator pedal to give orders to the eccentric shaft through the engine management system, and then the shaft changes the shaft point of the intermediate follower to determine the degree of valve lift. The lift can be changed between 0.2 mm and 9.8 mm, and the engine can be controlled in all directions whether it is idling or running at full load. Dual VANOS variable valve timing technology: In addition to the variable valve lift of Valvetronic, BMW's dual VANOS system changes the valve profile by rotating the intake and exhaust camshafts to optimize engine power, emissions and fuel efficiency. VANOS is short for "variable camshaft control" in German. This feature is not unique to N62 and N73 engines. At present, other BMW engines also have this technology, but VANOS plus Valvetronic technology is only available in N prefix engines.
