Abstract
LPG MPI injection technology for SI engines is very promising to control emissions and enhance performance compared to the conventional mixer type LPG supply system. A gaseous LPG injection system has an edge over the liquefied injection system in terms of durability and cost reduction. However, the volumetric efficiency of the gaseous system needs to be investigated to challenge that of liquefied injection system. In this work, measurements of volumetric efficiency were carried out to investigate the performance of gaseous LPG injection system compared with liquefied injection system. This work concludes that a gaseous LPG injection system shows the performance comparable to the liquefied injection system, and as for the next generation fuel supply system a gaseous LPG injection system is very competitive.
