Abstract

Seiring dengan perkembangan dunia industri, terutama meningkatnya jumlah produksi  dibidang transportasi menyebabkan peningkatan konsumsi bahan bakar minyak menjadi sangat besar. Bahan bakar minyak merupakan bahan bakar yang tidak dapat diperbaharui sehingga harus dilakukan penghematan. Salah satu cara yang dapat dilakukan untuk penghematan bahan bakar adalah dengan cara memasang kawat kasa di intake manifold, karena kawat kasa tersebut akan memecah campuran udara dan bahan bakar menjadi lebih homogen. Tujuan dari penelitian adalah untuk mengetahui bagaimana pengaruh pemasangan kawat kasa di intake manifold terhadap konsumsi bahan bakar dan emisi gas buang pada mesin bensin konvensional Toyota kijang 4K. Penelitian ini menggunakan variasi diameter lubang kawat kasa 1 mm, 1,3 mm, dan 1,6 mm pada putaran mesin 500 rpm, 1000 rpm dan 1500 rpm, dengan masing-masing dilakukan tiga kali duplikasi pengujian. Hasil penelitian pada putaran mesin 500 rpm dengan pemasangan kawat kasa berdiameter 1 mm, 1,3 mm, 1,6 mm dan intake standar menunjukan nilai konsumsi bahan bakar dengan masing-masing 26,7 cc/menit, 30 cc/menit, 43,3 cc/menit dan 40 cc/menit. Pada putaran mesin 1000 rpm dengan pemasangan kawat kasa berdiameter 1 mm, 1,3 mm, 1,6 mm dan intake standar masing-masing menunjukan nilai 60 cc/menit, 63,3 cc/menit, 70 cc/menit dan 70 cc/menit, dan pada putaran mesin 1500 rpm dengan pemasangan kawat kasa berdiameter 1 mm, 1,3 mm, 1,6 mm dan intake standar mempunyai nilai 73,3 cc/menit, 80 cc/menit, 83,3 cc/menit dan 83,8 cc/menit. Dari data yang disajikan tersebut menunjukan bahwa pemasangan kawat kasa dengan diameter lubang 1 mm mempunyai pengaruh yang cukup signifikan terhadap konsumsi bahan bakar dan emisi gas buang dibanding intake tanpa pemasangan kawat kasa dan pemasangan kawat kasa dengan diameter 1,3 mm, dan 1,6 mm. Pemasangan kawat kasa berdiameter 1 mm menjadikan konsumsi bahan bakar lebih irit 13 % - 33 % dan kadar emisi gas buang CO dan HC lebih rendah pada putaran mesin 1500 rpm. Kata kunci:Kawat kasa, Intake Manifold, Konsumsi dan Emisi gas buang, Toyota 4K.
