BMW to be even more fuel efficient?
Rather than making small engines to save on fuel bills, BMW are trying to recycle the wasted energy on larger engines, therefore not compromising the driving experience and power.
Efficient Dynamics already boost a long list of brilliant technology making cars better for the economy. These include Stop/Start, Brake Energy Regeneration, Electric Power Steering, Optimum Shift Indicator, Lightweight Engineering, Reduced Resistance, Low friction fluids, Active Aerodynamics. We take a look at how the company look to upgrade and add to their EffcientDynamics technology.
Cars produce energy when the car is driving, which standard cars typically waste. Advanced modern engines are able to save up to a third of the fossil fuels that are burnt. BMW are currently finding out various methods to recoup that wasted energy. Many pieces of technology have been mentioned including a thermoelectric generator and a turbosteamer. The thermoelectric generator mentioned is an advanced piece of technology, which converts heat into electricity.
The “Turbosteamer” section of the project, has the aim is of ultimately prevent energy being wasted from the exhaust. The idea is taken from technology with exactly the same principle that works with components based upon larger capacities. It is currently being utilised quite heavily in nuclear and power industries. This particular component has seen advanced developments, BMW have said.
It boils fluid with the exhaust system, so that it can be converted into steam which will provide power for an electric generator.
The Thermoelectric generator works differently. This creates an electric voltage using the “Seebeck Effect”. Potential is then created between separate thermoelectric semiconductors when their temperature is different.
It has been estimated that up to 10% of fuel consumption could be saved daily on routine drives. A prototype of the Turbosteamer has been placed on the BMW 5 Series for testing purposes. Testing has indeed shown that up to 10% on long distance journeys can be saved on fuel. BMW have mentioned that the main target is for 25% on fuel to be saved in the future.
Is this the most efficient way forward? Could other technologies beneficial technology be invested in instead? It is believed the whole project will be up and running in around 10 years.
