Abstract :
ABSTRAK\r\nPenelitian ini bertujuan untuk menganalisis pengaruh pemasangan catalytic converter terhadap emisi gas buang dan performa mesin pada mobil Kijang Super 7K tahun 1996. Latar belakang penelitian didasarkan pada tingginya emisi gas buang kendaraan bermotor yang berkontribusi terhadap pencemaran udara, terutama pada kendaraan generasi lama yang belum dilengkapi catalytic converter. Metode yang digunakan adalah metode eksperimen dengan membandingkan hasil pengukuran emisi gas buang sebelum dan sesudah pemasangan three way catalytic converter. Pengujian dilakukan menggunakan alat gas analyzer untuk mengukur kadar karbon dioksida (CO₂) dan hidrokarbon (HC), serta perhitungan efisiensi termal mesin. Hasil penelitian menunjukkan bahwa sebelum pemasangan catalytic converter, kadar CO₂ sebesar 5,4% dan HC sebesar 5414 ppm. Setelah pemasangan, kadar CO₂ meningkat menjadi 5,6%, sedangkan HC menurun menjadi 3258 ppm. Penurunan HC sebesar 2156 ppm menunjukkan bahwa catalytic converter mampu mengurangi kandungan hidrokarbon pada gas buang. Selain itu, efisiensi termal mesin meningkat dari 36% menjadi 41% setelah pemasangan catalytic converter. Dengan demikian, pemasangan catalytic converter pada mobil Kijang Super 7K tahun 1996 memberikan pengaruh positif terhadap penurunan emisi hidrokarbon dan peningkatan efisiensi termal mesin, meskipun hasil emisi yang diperoleh masih belum memenuhi standar emisi yang ditetapkan pemerintah.\r\n\r\nKata Kunci: catalytic converter, emisi gas buang, hidrokarbon (HC), karbon dioksida (CO₂), efisiensi termal.\r\n\r\nABSTRACT\r\nThis study aims to analyze the effect of installing a catalytic converter on exhaust gas emissions and engine performance of a 1996 Toyota Kijang Super 7K. The study was motivated by the high level of vehicle exhaust emissions that contribute to air pollution, particularly in older vehicles that are not equipped with catalytic converters. An experimental method was employed by comparing exhaust emission measurements before and after the installation of a three-way catalytic converter. Emission testing was conducted using a gas analyzer to measure carbon dioxide (CO₂) and hydrocarbon (HC) levels, while engine performance was evaluated through thermal efficiency calculations. The results showed that before the installation of the catalytic converter, CO₂ emissions were 5.4% and HC emissions were 5,414 ppm. After installation, CO₂ emissions increased slightly to 5.6%, while HC emissions decreased to 3,258 ppm. The reduction of 2,156 ppm in HC emissions indicates that the catalytic converter effectively reduced hydrocarbon pollutants in the exhaust gas. In addition, the engine\'s thermal efficiency increased from 36% to 41% after the installation. Therefore, the addition of a catalytic converter to the 1996 Toyota Kijang Super 7K had a positive impact on reducing hydrocarbon emissions and improving engine thermal efficiency, although the emission levels obtained still did not fully comply with government emission standards.\r\nKeywords: catalytic converter, exhaust emissions, hydrocarbon (HC), carbon dioxide (CO₂), thermal efficiency.
