Hot exhaust gas is sent to the exhaust manifold through the exhaust valve. The mixture of exhaust gas passes through the manifold to a catalytic converter. Due to partial combustion, the gases entering the catalytic converter consist of carbon monoxide, unburned hydrocarbons and nitrogen oxides, which are all harmful to the environment. The O2 sensor sends this information back to a computer that helps regulate air-to-fuel ratio and emissions.
