“…Ethanol fuel produced a higher BSFC than the other fuels due to its lower heating value, which means that a considerable amount of fuel is consumed to produce similar effective power. Similarly, Mustafa and Gitano-Briggs [15] found that LPG produced slightly higher BSFC than gasoline at all operating conditions. Figure-4 shows the peak fire temperature of gases inside the combustion chamber, as a function of compression ratio predicted by the model at an engine speed of 2500 rpm for gasoline, ethanol, and LPG fuels, respectively.…”

“…Numerous analyses of exhaust gasses of combustion engines indicate that LPG fuel systems are more favourable that units fuelled conventionally [12,14]. Bearing in mind that there is still a vast number of vehicles using fourth generation gas installations (particularly in African countries), the author of this article is convinces that work on improving the design of this fuel system should be continued.…”

“…reducing the usage costs due to decreased con-• sumption of petrol, which is a more expensive fuel than LPG; improving the usefulness factors of the engine, • since every change of the power source causes the controlling computer (ECU) to "re-learn" the supply map, with the engine generating less power and torque [16]; decreasing the level of harmful emissions in exhaust gasses by • limiting the emission of carbon monoxide and dioxide, in line with the current trends in the automotive industry (combustion of LPG produces fewer substances that are harmful to the environment that combustion of petrol [12]). Another advantage of the proposed solution is also the cost of the modification (calculated on the basis of the costs incurred by the author in relation to the construction and installation of the device) which is approximately 10% of the cost of adjusting a vehicle to be powered with an alternative fuel system.…”

The primary advantages of this fuels system (mainly, the reduction of operation costs) are well-known among drivers. The disadvantages are not so notable among users, although they are equally or even more important.It has been observed that recently, the intensity of research on fourth generation gas installations has decreased, mainly due to the technological advances in vehicle design (mass introduction of direct fuel injection). Modern combustion engines required the development of new solutions for gas installations, using the fuel in its liquid state (LPLi) [5].The installation of an alternative fuel system usually entails a decrease in the engines usefulness factors (power and torque). This, however, can be alleviated with a well-designed intake system. The heat necessary to change the state of LPG can be obtained from inlet air, thanks to which the temperature of the fuel increases while the temperature of the air is decreasing, contradictory to its density. The engine's volumetric efficiency is therefore improved [11] and, consequently, it produces more power and torque.Injection of any type of fuel (LPG included) entails decreasing its pressure (the pressure of LPG before the injector is higher by approximately 1 bar than the pressure in the engine's inlet line [2]). Expanding fuel draws energy in the form of heat from its nearest surroundings (the outlet nozzle and the air drawn by the engine), which in extreme cases may lead to ice forming on the injector nozzle and cut off the supply of LPG. This situation depends on the geometry of the injector (mainly, the diameter of the outlet nozzle) and the engine's operating parameters. The operating parameters of an engine are determined by the users of the vehicle, its designers may however, through optimization for example, change the geometry of the elements of the fuel supply system, and therefore prevent extensive cooling of injector nozzles [6].A team of scientists in South Korea has indicated that the composition of the fuel-air mixture has a significant influence on the velocity andrzej BorawSki Modification of a fourth generation LPg instaLLation iMProving the Power suPPLy to a sPark ignition engine Modyfikacja instaLacji LPg iv generacji PoPrawiająca jakośćProcesu zasiLania siLnika o zaPłonie iskrowyM*

“…Fuel consumption using propane is also less than gasoline due to higher energy content of propane. While combustion of propane produces very few emissions compared to gasoline, it shows a slight reduction in power because of poor volumetric efficiencies [11]. However, this reduction in power can be improved by several alternative methods provided by various researchers.…”

“…However, this reduction in power can be improved by several alternative methods provided by various researchers. One of the methods is to increase the compression ratio which results in improving the performance of engine under naturally aspirated conditions and by applying supercharger or turbocharger, which helps in supplying more air to the engine for the combustion of fuel [4,[10][11][12]. Gaseous Light-Duty vehicle cannot attain this advantage and hence do not have optimal engine efficiency [7,13].…”

This study focused on the computational and parametric research on a single cylinder spark ignition engine using dual-fuel, 100 % gasoline and (10 %, 20 %, 30 %) propane in gasoline on volume basis as an alternative fuel for investigating the performance and emission characteristics of spark ignition engine. The performance parameters Brake power, Torque, Bsfc, and Bmep were examined using Avl Boost software. In addition, the exhaust emissions like nitrogen oxide, carbon monoxide, hydrocarbons were also measured. The (10 %, 20 %, &30 %) of propane in gasoline decreases in power compared to 100 % gasoline, however engine fuelled with 10 %, 20 %, and 30 % propane in gasoline shows reduction in specific fuel consumption. The study investigates the effect of dual-fuel propane and gasoline on a fourstroke single cylinder spark ignition engine. The study was carried out at varying percentage load and varying compression ratio for constant engine speed. The focus of this parametric study tries to investigate the effects of replacing individual gasoline and propane with the optimum mixture of 10 %, 20 %, and 30 % propane in gasoline on volume basis in spark ignition engine in order to improve its performance and emission characteristics.
