Sporadic surge blows
Surging of the turbocharger can occur during certain operating conditions
such as when reducing the engine performance quickly when manoeu-
vring. At the same time, the flow direction in the compressor is momentari-
ly reversed. Such sporadic surge blows do not impair the safe operation of
the turbocharger.
 A surge blow is accompanied by a loud bang and escape of hot air
from the filter silencer.
