Exhaust system Law in the United States and other countries to not have a catalytic converter. Converters may not be removed from a vehicle that is used only for "off-road" driving in the United States. The main purpose of a catalytic converter on an automobile is to reduce harmful emissions of hydrocarbons, carbon monoxide and nitrogen oxides into the atmosphere. They work by transforming the polluted exhaust components into water and carbon dioxide. Cat-back (also cat back and catback) refers to the portion of the exhaust system from the outlet of the catalytic converter to the final vent to open air. This
Exhaust heat recovery system parts of embedded technologies on F1. Besides, heat recovery will be mandatory for the first time in 2014’s F1 Championship. Manufacturers, like Renault (ERS-H), test their systems, which also drives the turbo to improve its reactivity –and the torque at low regime- after braking. Exhaust heat recovery system In transportation, an exhaust heat recovery system turns thermal losses in the exhaust pipe into energy. This technology seems to be more and more of interest by car and heavy-duty vehicle manufacturers as an efficient way to save fuel and reduce vehicles’ CO emissions. This technology can be used either on a
