The exhaust emission control system, is the last line of defense, against harmful hydrocarbons (air pollution).

So, any shortage of spark or if the spark occurs, at the wrong time. Then, incomplete combustion and higher hydrocarbons will result. The exhaust emission control, consists of three additional systems. The secondary air injection system, the exhaust gas recirculation (EGR) system and finally the catalytic converter.
