Chemistry! The actions of the engine emissions and the exhaust system all work together to change the emissions from bad emissions to good emissions, if sulfur smell is considered good! The burnt fuel is mixed and remixed in the engine to ensure a good burn of the fuel. The resultant pollutant is then passed through the exhaust catalytic converter and its chemistry is changed to a less pollutant chemical. All the chemistry terms mean a lot to the designers and the EPA but to most of us it takes a large amount of equipment we cant afford to check the emissions amounts. Our best check is the smell. When we smell the sulpher it just means the car is doing what its supposed to do. If you want the chemistry specifics there are loads of papers on the subject. Just do a search for CAR EMISSIONS. They should fill your nights with reading material and all types of letters and numbers to impress your friends.
