Prediction model of road vehicle noise which could be regarded as discontinuous linear sound was as following: (1) Type: Leqi—equivalent continuous A-weighted sound pressure level of i type vehicle LAi—sound pressure level of i type vehicle radiated noise at reference point; dB T—evaluation time, generally for 1h; Ni —traffic flow of i type vehicle, vehicle / h; Vi —vehicle speed, km/h; ro—distance from reference point to lane; generally for 7.5 meter; r —distance from precalculated position to lane; α—attenuation factor related to absorption characteristics of mulching material, generally for 0.5 in rural area; △S—additional attenuation due to obstructions such as buildings, terrain, embankments, cuttings during noise transmission, dB 2)Equivalent continuous A-weighted sound pressure level of nighttime If the traffic volume of nighttime was less than 300Veh/h, “(2)”should be applied for noise prediction, otherwise, “(1)”used[3]

Research on gasoline antiknock additive affect to vehicle LI Jin (1 Shanghai University of Engineering Science, Shanghai lijin0106@126.com) Keywords: MMT, emissions, oxygen sensor, three-way catalytic converter Abstract: MMT had been used widely as an antiknock additive in petrol.
If the old catalytic converter with MMT influence, the catalyst surface will cover with a layer of coating material, leading to the gas through its surface contact area is reduced, so that the catalyst conversion efficiency decreased.
