High fuel prices cause vehicle users to seek cheaper alternatives for fuelling IC engines. The most popular way of reducing fuel costs is the instalation of an LPG gas system. Correct operation of a bi-fuel engine powering system is dependent on proper installation and setup of the LPG system, including proper regulation of LPG management unit parameters. The focus of this work was to investigate the effect of short- and long-term adjustments performed by the engine management unit. By interfering with LPG management unit parameters, disadvantageous adjustments in fuel-air ratio were made to investigate harmful substance emissions. Substantial differences in exhaust gas composition were shown before and after adjustments were made. The research results included the effect of short- and long-term adjustments on both engine power and exhaust gas composition.
