Abstract

Spark plug is an important component to generate sparks in the combustion chamber. The sparks from the spark plug is used to ignite the air-fuel mixture in the internal combustion chamber of the engine. This project was carried out to make the performance comparison of the engine by using the spark plug which have different material of the central electrode . Furthermore, this study is conducted on 3 types of the spark plug which have different material of the central electrode namely Iridium, Platinum and Nickel-Alloy spark plug. The engine performance is measured based on the Power ( bhp) and Torque (Nm) output of the engine . The experiment is conducted by using chassis dynamometer testing machine , where the vehicle engine used for the experiment is Proton Saga FLX 1.3 (A) CVT DOHC ( Model No : S4PE810820). During the experiment is carried out, the experiment data is taken out by using the WINPeP7 Dynamometer software for D gear with engine speed from 3000 RPM until 5200 RPM. This study proved that the Nickel-Alloy spark plug shows a higher engine power output and torque which result the best spark plug to be used in small engine capacity. This is because Nickel-Alloy has higher value of electrical conductivity [David G. Rethwisch (2010)]. The higher the electrical conductivity, the more conductive the material is. Higher engine power output shows at 5200 RPM with 169.8 bhp while in other hand, the higher engine torque shows at 4000 RPM at 75.5 Nm.
