Pengaruh Bahan Bakar LPG Sistem Manifold Injeksi terhadap Performa Single Cylinder Spark Ignition Engine

Abstract

This study is a continuation of previous studies with respect to conversion from fuel oil to LPG fuel (Liquified Petroleum Gas) using the type 1 injection system. This system also known as manifold injection and the simplest injection design for a carburetor system, which it is expected to improve fuel supply. Chassis dynamometer was used for measuring Torque and power engine. Gasoline and LPG as fuel were used in this study. The results show that the efficiency thermal increase around 6,28% when using LPG fuel with the type 1 injection system. However, the torque, engine power and specific fuel consumption were decreased at single cylinder spark ignition comparing with gasoline fuel.
