ECU zawsze dąży pod małym obciążeniem do składu mieszanki stechiometrycznego - czyli lambda 1 a to odpowiada dla LPG AFR 15,5 przytocze fragment z instrukcji LC-1 :Warmooz pisze:ghost, to że afr dla lpg powinno być 15,5 to wiadomo, ale sonda lambda nie mierzy lambdy tylko stosunek paliwa/powietrza więc jeśli nie zmienisz nastawień sterownika benzyny to w CL będzie dążyć do 14,7.
For gasoline-driven engines, the theoretically optimal air fuel ratio is 14.7
pounds of air for every pound of fuel. At this ratio, theoretically, all available oxygen in the air
combines with all available fuel. This ratio is called the stoichiometric ratio.
Stoichiometric for different fuels are as follows:
Gasoline 14.7
LPG (Propane) 15.5
Methanol 6.4
Ethanol 9.0
CNG 17.2
Diesel 14.6
The measurement Lambda is the actual air fuel ratio over the stoichiometric ratio. A Lambda
measurement of “1” equates to the air fuel ratio of 14.7 (for gasoline engines). When Lambda is
less than 1 the engine runs “rich”, i.e., unburned fuel exists in the exhaust stream. If lambda is
greater than 1 the engine runs lean, i.e., free oxygen (02) is present in the exhaust. Depending on the engine, maximum power is typically delivered when the engine runs slightly rich (for example at lambda values of 0.8 to 0.9 for most engines).
