With the increasing concern for the environment, the drive to minimize emissions ofCO2<\/sub>, nitrogen, soot and other harmful substances, the exhaust has become an “exhaust system. Exhaust gases became “emissions,” and the exhaust system was fitted with more and more components and additional things – catalytic converters, lambda probes, sensors, particulate filters, AdBlue – to reduce the emission (discharge) of harmful exhaust gases. Thus, cars with internal combustion engines received a true “emissions system.<\/p>\nExhaust basis of emission system<\/strong><\/h2>\n
