Performance comparison of one cylinder combustion engine with variations of compression pressure & octane number gasoline

Abstract

Nowadays, automobiles and motorcycles manufacturer produced more powerful and efficient engines. This engine usually has high compression pressure to achieve high performance and economic gasoline consumption. Unfortunately, only few people known that high compression engine requires high octane number gasoline. The aim of this research were to find out the differences of power & torsion output of one cylinder combustion engine which given several compression pressure variances using Pertamax & Pertamax racing gasoline. Dynamometer test has been carried out to find the performance difference of one cylinder combustion engine. The results shown that the highest compression pressure engine (11,8 Kg/cm2) using Pertamax racing gasoline (RON 100) produced highest power output at 7,8 KW with torsion output at 10 Nm. Meanwhile, the lowest compression pressure engine (10 Kg/cm2) using Pertamax gasoline (RON 92) produced lowest power output at 4,2 KW with torsion output at 3,8 Nm.

Performa motor bakar silinder tunggal dengan variasi angka oktan bahan bakar dan tekanan kompresi

“…Faktor-faktor yang berpengaruh pada kinerja mesin pembakaran dalam diantaranya adalah kualitas bahan bakar yang digunakan dan tekanan kompresi dalam mesin (Taylor, 1985). Penggunaan bahan bakar yang kurang berkualitas, bisa berakibat pada kinerja mesin bisa menurun dan konsumsi bahan bakar meningkat (Pulkrabek, 1997). Mesin pembakaran dalam yang umumnya digunakan pada sepeda motor dan mobil memiliki komponen silinder yang berisi piston atau torak yang bergerak maju dan mundur (Ferguson dan Kirkpatrick, 2015).…”
