The main aim of this work is to explore the injector performance in terms of fuel mass flow rate and discharge coefficient when ethanol is in use with gasoline injectors at elevated temperatures. The operating fuel injection was at the pressures between 0.2 and 0.4MPa and the temperatures in a range of 40–80°C. A fuel injector test cell with electr...

... A single point port fuel injector was employed to add gasoline fuel into air upstream of the combustion chamber [11]. Gasoline fuel under controlled pressure of 1 bar was injected through a liquid-to-liquid heat exchanger immersed in a water bath (Lauda, Model Ecoline 011) with a temperature controller (Lauda, Model E200). ...
Cleaner diesel engines have been successively developed to meet a compromised solution for issues concerning performance and emission regulation. Combustion and exhaust gas after-treatment technologies are exhaustively settled to resolve those problems. A key improvement of the emissions is diesel dual fuel combustion that increases operating range of the premixed combustion. The main aim of this work is to explore the heat release, fuel consumption, and thermal efficiency of a single cylinder diesel dual fuel engine. An intake port fuel injection of gasoline with the flow rates between 0 and 0.06 g/s was accomplished to form a premixed charge prior to induction into the combustion chamber and ignition by the main diesel fuel. The engine was operated on medium load at 1700 rpm without exhaust gas recirculation. An engine indicating system composed of a cylinder pressure transducer and a shaft encoder was used to investigate combustion characteristics based on the first law of thermodynamics. The combustion of higher gasoline pre-mixer increased heat release rates, shortened combustion duration, and increased maximum cylinder pressure than neat diesel combustion. Increasing gasoline proportion reduced the diesel fuel and total fuel consumptions. This enhanced the engine thermal efficiency over the diesel baseline combustion.
Today's dependence on fossil fuels causes shrinkage of fossil fuel in the earth, especially in industrial sector and transportation that is highly depended on petroleum. Industry and transportation agents have changed the use of fossil fuels to alternative fuels such as ethanol fuel. Ethanol continues to be researched and developed to reduce people's dependence on fossil energy. But the use of ethanol fuel cannot be applied a hundred percent in industrial machinery and transportation machinery because the engine that used has a specification for gasoline if we want to use ethanol as an alternate for the main fuel, so it has to changed the components of that engine. Things that could be done at this time is mixes ethanol and gasoline fuel so that the use of gasoline can be minimized without changing the engine components used. This study discusses the effect of a mixture of gasoline and ethanol on a gasoline engine. This study discusses the characteristic of gasoline and ethanol mixture on gasoline engine. This study discusses the characteristic of gasoline and ethanol mixes. This study summarize the result of research in ethanol-gasoline sector since 2008 - 2019 with a special study that covering about the spray characteristic with heating of ethanol-gasoline fuel, octan number and engine performance. The parameters of this study focused on the results of injection spray, torque, power, specific fuel consumption and the effect on emissions products, carbon monoxide, carbon dioxide, hydro carbon and discussed the advantages and disadvantages of a mixture of E0 to E60 gasoline and ethanol fuel in a gasoline engine. It can be seen that the increase of performance and thermal efficiency by adding ethanol fuel mixture to the gasoline engine and reducing exhaust emissions from combustion of ethanol-gasoline. however there is a limit that the ethanol-gasoline mixture if the mixture exceeds the mixture's boundary so it will causes a decrease in engine performance.
