RESEARCH OF THE AIR TEMPERATURE INFLUENCE ON FUEL CONSUMPTION OF A PASSENGER CAR CONVERTED TO OPERATE ON LIQUEFIED PETROLEUM GAS

Abstract

Due to the rapid growth of environmental pollution from mobile sources, the part of alternative fuels use is increasing. One of these for motor vehicle is liquefied petroleum gas (LPG). This study focuses on the LPG use by Mitsubishi Lancer X passenger car in driving conditions. Based on the results of the previous studies analysis, the most significant factors affecting the change in fuel consumption by motor vehicles were identified. It was proved that the decrease in the ambient temperature from +30 to –20 °C leads to an increase in gas consumption from 11.2 to 13.6 l/100 km. In addition, at air temperatures from –20 °C and below, the gas-fueled engine is unstable.
