Abstract

One of the components in an ignition systems is a spark plug device. It is to provide the spark in the internal combustion chamber to kindle the compressed air-fuel mixture. The project conducted is to determine the performance of vehicle engine and the finest spark plug by using different kind of material of the centre electrode and different diameter of centre electrode in order to produce high power output and torque of the engine and also to identify and overcome the problem of excessive hydrocarbon release from the exhaust. Besides, this project executed on three types of spark plug which have diverse material and diameter of centre electrode namely Nickel Alloy, Platinum and Iridium spark plug. The vehicle engine performance is measured based on the power output (HP), Torque (Nm) output and the hydrocarbon emission level (ppm). Perodua Myvi 1.3 Standard G Auto (2015) used in order to perform this experiment. This experimental is carried out without the actual road condition but instead by using the chassis dynamometer. While carry out the experiment, all the data needed is recorded by using the Dyno-Max Pro data acquisition software. In order to ensure safety measure, the engine is allowed revving from 3000 RPM until 4000 RPM. At the end, it was proven that the Iridium Spark plug shows higher performance in terms of power output of 72.63 HP, torque output of 95.3 Nm and less hydrocarbon release of 5 ppm when engine speed reaches maximum speed. This is because Iridium plug has higher ignitability to ignite the air-fuel mixtures thus make the perfect combustion process.
