Turbocharger noise
Fundamental phenomena of noise of internal combustion engines

Engine supercharging is a way of increasing power without increasing engine size . At present, we no longer design a naturally aspirated diesel engine, as the specific performance would be insufficient for the power requirements of modern vehicles. Environmental imperatives concerning reductions in fuel and CO₂ emissions are driving the design of engines with better efficiencies. The reduction in engine size makes it possible, on the one hand, to reduce friction losses and, on the other, to better adapt vehicle operating characteristics to areas...
