Abstract
There is a clear trend towards retaining heat in the engine compartment for as long as possible in order to benefit fuel consumption. At the same, it is becoming increasingly difficult to achieve a quiet and pleasant exterior noise, because more efficient combustion is usually noisier combustion. According to Rieter and Nissan, both problems can be solved with clever encapsulation that, at an acceptable cost, cuts CO2 emissions by 2.5 g/km and reduces exterior noise by up to 5 dB(A).
