Performance and emission characteristics of LPG in a spark-ignition engine

Abstract

This experimental study was carried out to understand the characteristics of a liquefied petroleum gas (LPG) compared to Pertamnina fuel product such as Pertamax (RON 92) and Pertamax Turbo (RON 98) in spark ignition engine. In our project, liquid fuel delivery system was controlled by the carburettor and conversion into LPG fuel supply system was controlled by Arduino Uno. The experimental result showed that liquid fuel was reach more better motor performance than the LPG, the highest power was reach by Pertamax Turbo of 7.5 HP at engine rpm 5,750 rpm, followed by Pertamax of 6.05 HP at engine rpm 6,050 rpm, and the lowest power was 2.61 HP was reach by LPG at 11,650 rpm. On the other hand, HC, CO, and CO2 of LPG fuelled engine resulted in the lowest emissions benefit over a wide range of engine operating condition.
