Combustion defaults
Valve overstressing due to combustion defaults
Cause:
Significant increased pressure and temperature loads occur in the combustion chamber as a result of combustion defaults.
Significant increased pressure and temperature loads occur in the combustion chamber as a result of combustion defaults.
Consequence:
The valve head cannot withstand the high thermomechanical loads and bends inwards. This results in so-called tulip formation and causes fractures in the area of the valve head.
