La description

Engine exhaust system components]: exhaust manifold, three-way catalytic converter, oxygen sensor, muffler [engine exhaust system components function]: 1, exhaust manifold: connected to the engine cylinder body, concentrating the exhaust gas in each cylinder to the exhaust main pipe. 2, three-way catalytic converter: HC, CO and NOx (nitrogen oxides) and other harmful gases in the exhaust gas through the oxidation and reduction into harmless carbon dioxide, water and nitrogen. 3, oxygen sensor: through the detection of the content of oxygen ions in the exhaust gas to obtain the air-fuel ratio signal of the mixture, the signal will be converted into an electrical signal into the ECU.
