Research on Gasoline Antiknock Additive Affect to Vehicle
MMT had been used widely as an antiknock additive in petrol. It can enhancing the vehicles dynamic performance and reduces fuel consumption, but causes some negative impact on vehicle emissions. In this paper, the author research on the emission performance of a vehicle which meet Stage IV emission standard use gasoline containing MMT run for 50,000km.The test results show emission pollution such as CO, HC and NOx increased by MMT which result in three-way catalytic converter deterioration quickly. MMT also made the oxygen sensor deterioration and cause high NOx emission.
