ABSTRACT
The production of engines using turbocharged stratified injection technology has increased rapidly in recent years. In addition, the use of liquefied petroleum gas, which is an environmental and economical fuel, is increasing in vehicles. While liquefied petroleum gas cannot be used in turbocharged stratified injection engines before, liquefied petroleum gas kits have become applicable to these types of engines with the development of technology. Turbocharged stratified injection is used to provide the first ignition of liquid fuel in engines. Therefore, liquid fuel is sprayed from the injector and then added on liquefied petroleum gas to burn liquefied petroleum gas. Thus, unlike other systems, liquefied petroleum gas in use with the increase in efficiency is also provided. Alcohols (ethanol, methanol, butanol, etc.) biomass fuels are alternative fuel characteristics. There are many studies on the use of alcohols in internal combustion engines. What distinguishes this study is that turbocharged stratified injection is used as a pilot fuel to burn liquefied petroleum gas in an engine. In the study, a vehicle with a turbocharged stratified injection motor equipped with prins liquefied petroleum gas system was used. For this purpose, the effects of 5% (E5), 10% (E10), and 20% (E20) ethanol addition on engine power, engine torque and exhaust emissions were investigated. The vehicle experiments were carried out by increasing the engine speed from 500-5500 rpm in the chassis dynamometer. The findings showed that with E10+liquefied petroleum gas fuel, there is an increase in engine power and engine torque. There is also a reduction in all CO, CO2, and HC emissions.
