So the guy with the high RVP race gas is ready to go quickly after one, or even no. But with highly volatile, high actual Reid Vapor Pressure fuel, adequate vaporization can occur with cool. But, the engine is hot, and the actual A/F in the combustion chamber is still leaner- than- optimal, and HP is reduced and sometimes detonation occurs until several seconds at WOT when the combustion chambers finally get the 1. But then, as the engine heat climbs, enough of the stale fuel becomes vaporized earlier and as actual A/F in the combustion chamber becomes richer than 1. Then, those unburned globs and droplets finally vaporize and burn out in the hot exhaust pipe, and the wideband O2 sensor downstream registers a happy 1. Even though measured air and fuel flow might be 1.Ī/F in the combustion chamber might only be 1. And we now listen to knock while testing so damage from deto is now rare.īut others come to the line with icewater in their engines! What gives? The guys needing to ! A combination of low velocity airflow from huge carbs and low volatility fuel requires lots of engine heat to create adequate vaporization.
Dyno seizures are caused by 1) dyno operator error, 2) engine owner greed, or 3) inadequate octane and/ or volatility. But I like to think that I learned a little something from each seizure. Gallon jugs of industrial strength muriatic acid, (used to dissolve aluminum smeared onto cylinder walls by pistons trying to grow larger than the bore size), are cheaper when you buy cases of four! So I am surely an expert on lean seizures, detonation and preignition. Your One-Stop Shop For All Your Industrial Supply Needs Please Contact Us For a Formal Quote +1 ( 281) 310 – 0628.

And I am confident that I have seized more pistons in those 2.
I have been dyno tuning/ testing motorcycles, snowmobiles and quads with a fully instrumented Super. The vapor of the liquid gasoline burns, and that.
