THE INFLUENCE OF SELECTED GASEOUS FUELS ON THE COMBUSTION PROCESS IN THE SI ENGINE

Summary. This paper presents the results of SI engine tests, carried out for different gaseous fuels. The analysis carried out made it possible to define the correlation between fuel composition and engine operating parameters. The tests covered various gaseous mixtures: methane with hydrogen from 5% to 50% by volume and LPG with DME from 5% to 26% by mass. The first group, considered as low-carbon-content fuels can be characterized by low CO2 emissions. Flammability of hydrogen added in those

SELECTED ASPECTS OF THE USE OF GASEOUS FUELS BLENDS TO IMPROVE EFFICIENCY AND EMISSION OF SI ENGINE

biofuels, LPG, or compressed natural gas (CNG), and the development of electric drives. An attractive option in counteracting the effects of the emission of internal combustion engines is alternative gas fuels, including biogas, natural gas, dimethyl ether (DME), hydrogen (H2), and mixtures of them. This article focuses on mixtures that are easy to obtain: natural gas and hydrogen (HCNG) and petroleum gases with dimethyl ether (LPG and DME). Their impact on engine performance, combustion
