Sažetak
In service emission test is used to check the operation and efficiency of vehicle's emission control (aftertreatment) system. In the Republic of Croatia in service emission test is mandatory for most of the passenger cars, but from some reason (unknown to the authors) LPG powered vehicles are exempt from the in service emission test. That means that for more than 55, 000 passenger cars in Croatia one knows nothing about the condition of their exhaust aftertreatment system. If the average age of LPG passenger car fleet, emission level, and total mileage are considered, it can be assumed that the correct operation of their exhaust gas aftertreatment system is questionable. To assess the condition of LPG fleet exhaust gas aftertreatment system, in the cooperation with the Centre for Vehicles of Croatia (CVH), a pilot study “In service emission test of the LPG powered passenger cars” was carried out. In service emissions were measured on a random sample of 500 LPG passenger cars during their regular periodical technical inspection. After the data analysis, it was concluded that 42.3% of the pilot study fleet failed the in service emission test, showing justification to further continue in service tests on a larger number of samples determined by design of experiment method. Data collected on a larger number of samples will be analysed to evaluate operation of LPG fleet emission control system and to determine malfunctions causing fail of in service emission test. Obtained results will be compared with the results of in service emission test of complete passenger cars fleet in the Republic of Croatia.
