Lambda controller
The purpose of the lambda controller is to prevent
injection of more fuel in the combustion chamber
than can be burned during a momentary load in-
crease. This is carried out by controlling the relation
between the fuel index and the charge air pressure.
The lambda controller has the following advantages:
▪
Reduction of visible smoke in case of sudden
momentary load increases.
▪
Improved load ability.
▪
Less fouling of the engine's exhaust gas ways.
▪
Limitation of fuel oil index during starting proce-
dure.
The above states that the working conditions are
improved under difficult circumstances and that the
maintenance costs for an engine, working with
many and major load changes, will be reduced.
