Effects of Fuel Type on Performance in Gasoline Engine with Electronic Fuel Injection System

Abstract

Gasoline engines with electronic fuel injection systems are recommended to use Pertalite type unleaded gasoline to produce a perfect combustion process so as to improve engine performance. However, the majority of vehicle owners prefer to use Premium type fuel and sometimes also mix it with other fuels, resulting in decreased engine performance. This is due to the low price of Premium and consumers do not understand the effect on engine performance. This research was conducted on a Toyota Avanza K3-VE 1,298 cc with an experimental method that aims to determine the performance of a gasoline engine with an electronic fuel injection system using several types of fuel. To find out the optimal engine performance, the test is carried out at maximum engine speed using a dynamometer bench. The results showed that the right fuel used in gasoline engines with electronic fuel injection systems is Pertamax type because it has optimal engine performance, which produces an maximum torque of 176.23 Nm and an maximum power of 105.83 Kw.
