Liquefied petroleum gas (LPG) as a medium-term option in the transition to sustainable fuels and transport

In performing the analysis of LPG fuel systems (the 1st, 2nd, 3rd, 4th, and 5th) for internal combustion engines (ICEs), special emphasis is put upon the thorough examination of their structural control diagrams. The critical review also provides a detailed description of characteristics and classification of fossil derived gases (LPG, CNG, and LNG) as fuels in motor vehicles, discusses different types of existing LPG fuel delivery systems and requirements to gas equipment, and presents a thorough analysis of the SI engine operation using LPG as a fuel.
