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.

Abstract

The total motor vehicle sales reflected an increase in people's mobility. Alongside this, the industry were also develop high compression engines to achieve optimal performance. This research aims to examine the effects of adding a cylinder head gasket and variations in the octane number of gasoline used in a single-cylinder internal combustion engine. Dynamometer testing was conducted to observe the differences in torque and power output. The test results indicate that an engine with a compression ratio of 11,8 Kg/cm2, coupled with the use of RON 100 gasoline, produces the highest power output, which is 7.90 kW, with peak torque reaching 9.93 Nm. On the other hand, the smallest torque is generated by the same engine when supplied with RON 92 gasoline, at 4.78 Nm, with the lowest power output of 5.43 kW.
