Consumption of gasoline in vehicles equipped with an LPG retrofit system in real driving conditions

Abstract

Vehicles equipped with an LPG retrofit system are always started on gasoline. Therefore, part of the vehicle's annual mileage will be run on gasoline. This article describes the results of tests conducted on a vehicle equipped with a propane-butane gas retrofit system (LPG system) regarding gasoline consumption in the LPG mode depending on the temperature at which the engine is started. The research was carried out on a passenger car from the C segment with an engine with indirect gasoline injection system. Based on these studies, the analysis of various vehicle use scenarios and the related gasoline consumption in relation to LPG consumption was made.
