Abstract
BMW’s turbosteamer is the first system to use the potential of waste heat in order to enhance the efficiency of the combustion process in the automobile. Applying the principle of cogeneration, fuel consumption can be reduced in a four-cylinder spark ignition engine by more than 10 per cent or, conversely, power and performance may be increased accordingly under relevant stationary operating conditions.
