Vechiles emit large amounts of emissions in towns of developing countries. This study is descriptive research. Analyzer gas as well as opacity were used to collect the necessary data. The objects of the study were motorized diesel engine as well as gasoline engine of various brands that operated around Sleman, a regency in Special Region of Yogyakarta, Indonesia. Those vehicles produce three main exhaust gases: CO, HC, and PM. The largest CO emissions, with figure reaching 6.92%, come from gasoline-powered Suzuki units released in 1993. Daihatshu units released in 1993 emit the largest HC emissions up to 538 ppm. Meanwhile, diesel-powered vehicles that produce the most Particulate Matter come from Mitsubishi that were released in 2008, with figure reaching 64.55%.HSU. The analysis of exhaust gas emissions will encourage vehicle owners who haven't yet passed their emission test to do regular maintenance as well as put the right type of fuel into their vehicles.

Human uses vehicles for mobilization from one place to another but there is using vehicle such as exhaust gas emission. This study aimed to identify the quality of vehicle exhaust gas emission in Sleman, Indonesia in 2019. The study was descriptive quantitative research. The data of vehicle exhaust emission and vehicle specification were gathered by means of using gas analyzer, opacity meter, and observation. The data resource was 133 vehicles that use gasoline engine and diesel engine.
