Besides, your engine is probably running better (maybe) because you placing your hand there doesn't entirely kill the engine but simply makes the air -
fuel ratio rich (this makes the engine smile).
Not exact matches
Rich air /
fuel ratios require a hotter plug to prevent fouling.
fuel ratio problem,
rich or lean, which can be even more complicated to sort out as suggested in the article.
The stratified charge puts a mixture that's
richer near the spark plug for easy ignition, while other areas on the combustion chamber have a leaner
fuel / air
ratio.
Wide - band lambda sensor analyzes the air -
fuel ratio and adjusts the lean /
rich mixture accordingly to keep the system in balance and to minimize emissions.
Prof Salby points out that while fossil
fuels are
richer in C12 than the atmosphere, so too is plant life on Earth, and there isn't a lot of difference (just 2.6 %) in the
ratios of C13 to C12 in plants versus fossil
fuels.
So if the C13 to C12
ratio is falling (as more C12
rich carbon is put into the air by burning fossil
fuels) then we can't know if it's due to man - made CO2 or natural CO2 from plants.
