Everyone wants to achieve low consumption and emission values. With the introduction of the current Efficient Dynamics engine family BMW has now managed to achieve an extraordinarily favorable relationship between these values and the mileage of a vehicle across all vehicle segments. The revised gasoline and diesel engines with three and four cylinders are now to prove that consistent further development can also set standards.
For the first time, BMW TwinPower Turbo technology became a common feature of all gasoline and diesel engines. This resulted in significant synergy effects in both the development and the production of the motors, which serve ecological as well as economic sustainability. In addition to the further development of the Efficient Dynamics engine family and the further reduction of consumption and emission values, there is also the simultaneous optimization of the performance characteristics. In addition to reducing the weight, running culture and acoustic comfort come first. The BMW TwinPower Turbo technology is used in the petrol engines a charging system, direct petrol injection, variable control of the stroke of the intake valves and the continuous adjustment of the opening times for exhaust and intake valves. Consumption and emissions are reduced again by up to 5 percent, and the power and maximum torque of the drive units increase by 5 kW / 7 hp and 20 Newton meters, respectively.
BMW TwinPower Turbo technology for diesel engines consists of a supercharger system with one or more turbochargers and common rail direct injection. These two central components will be significantly further developed for the revised drives. On average, they consume up to 5 percent less fuel and therefore emit up to 5 percent less CO2. In order to ensure even more spontaneous reactions to accelerator pedal movements and at the same time to increase the efficiency of the drive units, the turbo systems of all four-cylinder diesel engines will in future be used as step charging executed. A further developed oil circuit with switchable and therefore needs-based piston cooling and a modified belt drive for the auxiliary units are further innovations that contribute to an increase in efficiency. The acoustic properties of the four-cylinder diesel engines are also further optimized using a new bracing technology for the balancer shafts.
Together with the optimized combustion behavior and all other measures for exhaust gas cleaning, it is guaranteed that in the coming generation of the Efficient Dynamics engine family, all drive variants worldwide will meet both current and future legal requirements Meet emission reduction regulations.
