| Summary: | 碩士 === 國立中山大學 === 環境工程研究所 === 89 === During administer mobil source examine and control plan , we must estimate emission amount , curtail amount and curtail rate , to estimate the improve effection . But there has very few data of this aspect , especially real road driving pattern to calcul ate emission factory and amount . So it’s necessary to proceed this aspect investigate. The investigate have two parts include driving pattern and emission factor . Determine item is CO , THC and NOx .The result of driving Ping-tung area have faster speed,longer navigate time and larger acceleration and deceleration . The result of emission factor：CO is 6.79 (±3.39) g/km , THC is 1.63 (±1.27) g/km and NOx is 0.13(±0.14) g/km . Idle emission CO is 1.03%(±1.19%)，THC is 1400(±2138) ppm
