Undoubtedly, the changes spark ignition engines (hereinafter SI engines, Otto engines) have undergone under the last 20-25 years has been due to pressure from emission standards and fuel economy requirements becoming ever stricter. These regulations have equally influenced the every stage (from 1st to 5th generation) of LPG technology development while looking back in retrospective. Increasing emphasis on liquefied petroleum gas (LPG) as a clean, relatively low in cost and abundant energy source to provide affordable fuel-efficient transportation, encourages the search for the optimum approach to management of fuel, air and combustion to achieve the best results in vehicle power, fuel efficiency and low gaseous waste products. The development undertaken since then is still a work in progress leading to the course of establishing the new systems, including those for Otto engines with direct gaseous fuel injection as well as direct liquid LPG injection. 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.
