Rotten Egg Smell
A rotten egg smell in cars comes from a gas known as sulfur dioxide. The catalytic converter, fuel pressure regulator, fuel filter, etc., can exaggerate this gas if there's a processing fault, creating an odor.
Toxic combustion chemicals can harm humans and damage the car's catalytic converter, which controls emissions. So, even if the check engine light didn't pop, hurry up and take your car for an inspection.
In short, the car's emission system makes sulfur dioxide odorless. Roughly speaking, the catalytic converter transforms toxic gases and pollutants from the engine combustion process into safer-to-breathe gases.
However, when the catalytic converter has an issue, these gases get a free pass to produce bad smells and even cause allergies.
The symptoms might change if the vehicle's tank contains different brands of gasoline. Moreover, even old transmission fluid and the tailpipe's smoke color are clues of a problem.
