Re: Lambda sensor, worth reading!

Quote "At a lambda of 1.3 and above (about 19 to 1 fuel to air ratio), there's just too much fuel and the mixture won't ignite"

Think they are a little confussed as 19 to 1 fuel to air would empty the fuel tank in about 3 seconds.

Lambda 1.3 is 19:1 Air/Fuel would be dangerously lean

Below 10:1 would be too rich, looking for around 12.5:1 for performance and 16ish:1 for economy.

I guess 14.7:1 is to air on caution as the lambda doesn't want to run the engine too lean.

Just being picky now. Good article at explaining it though
