Premium automaker BMW Ag, announced that will design its upcoming new family of engines, both diesels and petrols, to share more standardized parts. The three-, four- and six-cylinder engines will have the same single-cylinder displacement of approximately 500 cubic centimeters and a common engine block design.
“Our goal is to have 60 percent of components shared between engines based on fuel type, and 40 percent commonality between gasoline and diesel engines,” said BMW’s head of development for inline engines, Harald Unger, at a press event recently.
Fuel intake and exhaust systems will share components based on the fuel type, gasoline or diesel. Mounting points for the powertrains will also be standardized for both transverse and longitudinal installations.
The new crop of power plants will also feature TwinPower Turbo technology. Like the company’s latest TwinPower Turbo 3.0-liter turbo inline-6, the new 2.0-liter engine will combine high pressure direct-injection and BMW’s VALVETRONIC intake control (hence the name: TwinPower) with a forced induction system consisting of a single twin-scroll turbocharger.
BMW’s engine program could mean a consolidation of suppliers. For example, Unger said two companies, Schaeffler Group and Hydraulik-Ring, supply variable valve timing mechanisms for gasoline four- and six-cylinder engines.
In the future there may be just one. The volume of identical variable valve timing mechanisms, which BMW calls Vanos units, would triple.
