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:
â–ª Reduction of visible smoke in case of sudden
momentary load increases.
â–ª Improved load ability.
â–ª Less fouling of the engine's exhaust gas ways.
â–ª 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.
