Sivistyksen vuoksi katselin Istasta ja se kuvailee asian näin:
"Super-knocking
Super-knocking is irregular combustion that occurs on highly turbocharged engines. Here, the maximum combustion pressure of approx. 100 bar rises to up to 200 bar. The causes of this are impurities in the combustion chamber (oil, residual gas, carbon particles) that trigger inflammation of the mixture before the actual point of ignition. This is why super-knocking cannot be eliminated by means of ignition interventions.
If the DME detects super-knocking, the power output is reduced to protect against engine damage. Brief super-knocking is caused by individual dirt particles. Super-knocking leads to short-term shutdown of the fuel injection (3 to 6 cycles) at the cylinder concerned. A fault is also entered in the fault code memory."
