Because increased food delivery service and quick delivery service using motorcycle, registration number of motorcycle was sharply increased and it could contribute on worsening air quality. This study two models(50㏄, 125㏄) of motorcycle were tested by three engine oil types. Two motorcycles were tested with CVS-40 mode for air pollutants such as CO, THC, NOx, Elemental Carbon(EC), Organic Carbon(OC), sulfate, soot and SOF(soluble organic fraction)

Hydrocarbons which are the main sources of VOCs from motor vehicles are emitted not only from the exhaust but also from evaporation of the fuel in storage and supplying systems. The important parameters to affect evaporative emissions are air and fuel temperature and fuel vapor pressure. Diurnal loss rises exponentially as air temperature and vapor pressure increase. The effects of vapor pressure on running loss are different as the capacity of canister. Tests with simulating real temperature and driving conditions show that hydrocarbons in evaporative emissions are more than that in exhaust gas in summer season because of the higher air temperature. The BTEX analysis of VOCs shows that toluene is the most emitter and benzene is the next and that photochemical ozone creation potential gets lower as vapor pressure decrease.
