Manufacture in our country and a motor vehicle sold executes for emission test of a certification that confirm availability whether is suitable in motor vehicle emission standard of our country at newly developing step on the motor vehicles. Emission certification test was carried out after calculation of deterioration factor through endurance laboratory test(millage accumulation) and then calculation that correspond in emission warranty(gasoline 160,000 km, diesel 80.000 km) in chassis dynamometer test. Final certification test result is satisfied air environmental protection law article 32 (emission standards) and then mass production. Sale is available. According to results of study, the ratio of a car that exceed appear to the LPG fueled vehicle(43%), diesel fueled vehicle(28%), gasoline fueled vehicle(24%) by emission standard test result. CO and HC appeared high emission level in a LPG car and NOx appeared diesel. Gasoline and LPG light motor vehicle CO's average, a light duty multipurpose vehicle PM's average emission standard for manufacture exceed. CO's average of LPG vehicle approximated in standard as 99% of emission standard. All item higher emission level appeared in light motor vehicle(lower 1,000cc) depend on gasoline fueled vehicle, especially 2500CC gasoline fueled vehicle was most good emission level. Need less driver's maintenance parts for improvement of this, and repairman judged that do not tempering adjustment of fuel system.

In Korea, the vehicle registration number of 2004 has been increased almost 4.4 times than that of 1990. Main reason of this considerable increase is the gravitation of population toward cities and rapid industrialization. In order to reduce air pollution caused by mobile sources under this condition, Korean government has regulated motor vehicle emission and strengthen the emission standards. Therefore vehicle manufacturers have to meet these standards and try to maintain performance of vehicles in warranty period. According to results of study, the ratio of a car that exceed appear to the LPG fueled vehicle(43%), diesel fueled vehicle(28%), gasoline fueled vehicle(24%) by emission standard test result.

We investigated the tailpipe VOCs emission from motor vehicle last year and continuously studied the evaporative emission of gasoline and LPG vehicle this year. On the basis of the results of these studies, the basic emission factor and management plan for motor vehicle related VOCs emissions are proposed.<br/> The result of this study shows that the diurnal breathing loss emission rate was large than hot soak emission rate about 2 times, and the evaporative VOCs emissions from ove<br/> 80,000km vehicle were 2 times larger than less 80,000km vehicle. As the fuel R VP increased from 7 to 11, the emission rate also increased more than 2 times.<br/> The individual composition of evaporative VOCs was different by fuel type. In case of gasoline vehicle, the order of evaporative VOCs composition was paraffins>aromatics>olefins, and some kinds of health effective aromatics like benzene, toluene, ethylbenzene, xylene were included more than 10%. In case of LPG vehicle, the most abundant component of evaporative and exhaust VOCs emission was butane.<br/>

In Korea, the vehicle registration has been steadily increasing. Main reason of this considerable increase is the gravitation of population toward cities and rapid industrialization. In order to reduce air pollution caused by mobile sources under this condition, Korean government has regulated motor vehicle emission and strengthen the emission standards. Therefore vehicle manufacturers have to meet these standards and try to maintain performance of vehicles in warranty period. According to results of study, the ratio of a car that exceed appear to the LPG fueled vehicle(43%). diesel fueled vehicle(28%). gasoline fueled vehicle(24%) by emission standard test result. CO and HC appeared high emission level in a LPG car and NOx appeared diesel. Gasoline and LPG light duty vehicle in CO's average. a light duty multipurpose vehicle in PM's average exceeded to emission standard at manufactured year. CO's average of LPG vehicle approximated in standard as 99% of emission standard. All item higher emission level appeared in light motor vehicle (lower 1.000㏄) depend on gasoline fueled vehicle. especially 2500㏄ gasoline fueled vehicle was most good emission level. Need less driver's maintenance parts for improvement of this. and repairman judged that do not tempering adjustment of fuel system. After repairing vehicle show lower emission level than did not one. User consider maintenance that make good emission level.

Emissions from automobiles have long been considered a prime source of pollutants involved in smog formation and ozone production. Especially VOCs are associated with serious environmental problems such as photochemical smog as well as human health effects. Since motor vehicles are a major source of VOCs, estimation of emission from mobile source is the most important factor to control VOCs in atmosphere. In this study in order to evaluate tailpipe VOCs emission from motor vehicles, mass emissions of non-methane volatile organic compounds from 20 vehicles were determined. Measurments were made on a chassis dynamometer using CVS-75 mode and speed specific drive mode depend on the driving velocity. Target VOCs are 53 compounds determined as the volatile ozone precursor. The individual VOCs composition of vehicle emission and emission rate were also determined. In case of gasoline vehicles, VOCs emission from over 80,000㎞ vehicles were about 46% larger than less 80000㎞ vehicles. The difference between benzene and toluene according to driving mileage was 44% and 26% respectively. The composition of VOCs were different by fuel type. The order of VOCs composition was paraffins(44%)>aromatics(34%)>olefins in gasoline vehicle emission, paraffins>olefins>aromatics in light duty diesel vehicle emission. The VOCs emissions were decreased as vehicle speed increasing. From these results we finally determined the various emission factor by kind of vehicle. In future, this research will be used for calculating total VOCs emission from automobiles.

In Rio de Janeiro in June 1992, The around world adapt convention on climate change which indicated to start international effort for prevention of greenhouse. According to agree the obligatory reduction of greenhouse gas specified Gyoto protocol, Our country which is 10th of the world in greenhouse gas emission, member of OECD wilt be pressured to reduce greenhouse gas. In this study in order to prepare obligatory reduction measure estimated the greenhouse gas emission factor and emission from automobile which is basic data to make emission statistics by Tier 3 method. To estimate greenhouse gas emission characteristics from automobile, greenhouse gas emission from was measured using driving pattern. CO₂, N₂O, CH₄ emission of passenger cars and light duty diesel vehicles were evaluated on chassis dynamometer for the cars selected by fuel, manufacturer, model year, displacement and CO₂, N₂O, CH₄ emission of heavy duty diesel engines were evaluated on engine dynamometer for the engine selected by manufacturer and production year.
