The Valvetronic system is the first variable valve timing system to offer continuously variable timing (on both intake and exhaust camshafts) along with continuously variable intake valve lift, from 0 to 10 mm, on the intake camshaft only. Valvetronic-equipped engines are unique in that they rely on the amount of valve lift to throttle the engine rather than a butterfly valve in the intake tract. In other words, in normal driving, the 'gas pedal' controls the Valvetronic hardware rather than the throttle plate

VALVETRONIC ENGINE TECHNOLOGY
1. INTRODUCTION
The automobile has been providing individual mobility for more than 100 years. This mobility is made possible first and foremost by combustion engines drawing their power from fossil energy carriers, which, even today, provide the foundation in generating mechanical drive power in the automobile. The primary objectives in developing drive systems are to curb fuel consumption and reduce CO2 emissions. In an effort to meet this challenge, the automotive industry is developing suit ....etc

MINI R56 model designations, 2007 - 2012:

R55 Clubman S

R56 Cooper S

R57 Cooper S Convertible

R58 Cooper S Coupe

R59 Cooper S Roadster

R60 Cooper S Countryman

Beginning with the production of the 2007 MINI R56, several of the models have been equipped with the Valvetronic intake system. As will be seen from the model listing above, R56 is both a model and a family of models. Different MINI body configurations were given different R codes.

Initially only the normally-aspirated model with the N12 engine was equipped with ....etc

international journal paper on valvetronic engine

In conventional petrol engines, when the accelerator pedal is pressed, the throttle butterfly opens to allow fresh air to come in. The fuel injection system measures the mass of air entering and injects the required amount of fuel.

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 long ....etc

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, offer ....etc
