Valvetronic Engine Technology
One of the latest and interesting innovations in the field is the Valvetronic Engine Technology from BMW. The 316ti compact is the first production car in the world featuring an engine controlled by VALVETRONIC air supply. Accordingly, the VALVETRONIC engine no longer requires a throttle butterfly, which has quite literally restricted the free ventilation of the internal combustion engine ever since its invention. Now VALVETRONIC replaces this conventional function by infinitely variable intake valve lift, offering a quantum leap in technology quite comparable to the changeover from the carburetor to fuel injection.
And at the same time clearly proves the outstanding competence and innovative power of BMW's engineers, VALVETRONIC going back to a BMW patent and manufactured exclusively on BMW's own machines and facilities
