Abstract

The decline in performance of a vehicle that has been used for a long time makes it less comfortable when used. The aim of this research is to determine the results of the effect of camshaft overlap duration on the power of a 110 cc petrol engine. To verify its performance, experimental research methods were used in this thesis research. The research results show that varying the duration of camshaft overlap has the effect of increasing vehicle power. For example, using a variation of the camshaft overlap duration of 38o produces the highest power with 7.45 (Hp) at an engine speed of 7000 rpm. This can happen because according to the theory that the greater the duration of the camshaft overlap on a vehicle, the better the flushing of the combustion chamber at top speed.

Abstract

The loss of performance in a motorcycle that has been used for a long time makes it uncomfortable when used. The purpose of this research is to determine the results of the effect of camshaft overlap duration on the performance of a 110 cc petrol engine. To verify its performance, experimental research methods were used in this thesis research. The research results show that variations in camshaft overlap duration between 12o, 15o, 18o (standard) 23o, and 28o have the effect of increasing vehicle performance. For example, using a variation of camshaft overlap duration of 28o produces the highest torque of 7,82 (Nm) at an engine speed of 6500 rpm and the highest power of 7.45 (Hp) at an engine speed of 7000 rpm and produces maximum BMEP 909,96 (KPa) at engine speed 6500 rpm. This can happen because according to the theory the greater the camshaft overlap duration on a vehicle, the better the flushing of the combustion chamber at top speed.
