The odor comes from the retention of excess sulfur compounds in the catalytic converter. Sulfur compounds may be the result of highly blended, additive-laced, oxygenated, reformulated gasoline. Here’s how. Cars now have three-way catalytic converters, which tend to store sulfur leftover from burning gasoline. This typically happens while the vehicle is being driven at steady highway speed. When you slow down and re-accelerate or the engine comes to an idle the air-fuel mixture becomes more concentrated with fuel. The richer fuel mixture creates a chemical reaction that leads to the release of stored sulfur in the form of hydrogen sulfide. It’s the hydrogen sulfide that has the nauseating smell!


So, if you routinely experience a rotten egg stench from your exhaust, try different brands of gasoline. If that doesn’t work, have a skilled technician check fuel mixture, tune-up, computer, and catalytic converter. When everything is functioning Commercial Three Bayperly there should be little or no noxious smelling hydrogen sulfide coming from your tailpipe.
