Technical and economic assessment of liquid petroleum gas modification/conversion on a gasoline engine in Turkey for time interval between 2016-2020. Selcuk University Journal of Engineering Sciences, 20 (02), 38-45.2757-8828https://hdl.handle.net/20.500.12395/45051A 1.2-liter gasoline spark ignition internal combustion engine of a Renault Symbol sedan vehicle was adapted to Liquid Petroleum Gas (LPG) fuel system in 2016. The LPG system utilizes LPG and gasoline fuels according to the operational needs. After modification, fuel consumption of the engine, fuel prices per liter, travelled distance in kilometers, dates and some additional data were recorded till November 2020. Collected data is processed for derivation of performance and economy indicators. Literature and web have been reviewed in order to find related works. Providing a solid application example of LPG conversion is aimed in this work. Also, a snapshot of fuel prices between 2016 and 2020 is being presented by graphical resolution. Approximately 12 to 15 times of initial investment cost has been returned till November 2020 by the LPG system. Also, slightly less CO2, i.e., 6%, has been emitted by means of the utilization of the system. Time resolution of the data is provided by graphics and integral data is also given. LPG conversion is found beneficial in terms of fuel cost. Also, viewed four years period does not reveal any performance problems in terms of energy spending per kilometer. However, engine additional amortization due to LPG system is not considered and this should be kept in mind.eninfo:eu-repo/semantics/openAccessCombustionConsumptionConversionEmissionFuel CostGasolineInternal Combustion EngineLPGArticle2023845
