Hello! i plan to produce new type of pigy-back device with connection to lambda sensor. for automatic fuel selection and lean burn mode. where can i read about working ethanol lean-burn solutions? |

interesting! how lean fuel mixture are you planning to have? and how much do you estimate to save on the lean burn mode? |

i will do more experiments with lean mixtures, but now i can see that i can get ethanol consumption about +5...+10% to gasoline consumption. i get some data about ethanol laminar burning speed and hope that will not be danger to burn output valves. i plan to modify signal from lambda sensor to obtain lean mixture instead stoich. and piggyback device will use signal from lambda sensor for automatical fuel selection. |

Thats the spirit, Obormot! The problem with lean burn is that when going lean, the burning speed will decrease, so U should advance the ignition timing for best economy. With a piggyback I see big problems fixing that, otherwise I like Ur idea. |
