Ensure coordination signal of the lambda probe (oxygen sensor) when working on gas with gasoline electronic control unit of the engine (ECU)

Switch the engine on gaseous fuel changes the nature of signalsfrom the lambda probe (the difference in the ratio of 1:14,7 / 1:15,7;see above). ECU engine several times trying to correct this imbalanceand the impossibility of that record occurrence of errors (faults),which subsequently can cause disabling other systems of the car. Toavoid similar situations in the modern control units gas fuel systems applied dispensers (GCE 2-generation), matching the signals of thelambda probes with self-diagnostic engine malfunction, or emulators ofthe lambda probe (including GCE and the 1 st generation).The latterallows you to simulate the work of the lambda probe to the catalystthat excludes the possibility of a gasoline engine management systembeyond the adaptive adjustment of the mixture (to be entered in theECU fault code and a bulb failure on the dashboard) in a car with GCE 1-th generation,or the work of the lambda probe after the catalyst(for systems with the norms of toxicity of the Euro-3),which makes itpossible to exclude the emergence of a failure to package the work ofthe sensor (for such systems we recommend GCE no less than the 2 ndgeneration). All this only affected cars with a catalyst, lambdaprobe, the system self-diagnostics and system power. Safety standardson foreign producers gas transport systems did not provide electricpetrol pump off to save fuel and maintain the circulation in thegasoline supply pressure. This eliminates the drying of rubber hosesand the likelihood of leakage.In addition, to ensure sufficientcooling electric petrol pump encouraged to maintain the level of fuelin the petrol tank of not less than 1 / 4 of its volume.
