Assessment and Analysis of Fuel Efficiency and Emission Control in Turbojet Engines (Published)
Emission control and fuel efficiency are important performances in modern aviation as the cost of aviation fuel is rising and the environmental issues are on the increase. Although the turbojet engines have a long and significant history in the evolution of the aircraft propulsion system, it is characterized as one of the engines that consume a lot of fuel and emit a lot of emissions compared to modern turbofan engines. The paper is a thorough evaluation of fuel efficiency and emission control system in turbojet engines through the evaluation of thermodynamic performance, the combustion, and the formation of pollutants. Specific attention is given to the compressor pressure ratio, combustion temperature, and the process of fuel atomization that affects the efficiency of engines and the level of emission. Key components of emissions such as carbon dioxide, nitrogen oxides, carbon monoxide and unburned hydrocarbons produced during combustion are evaluated by the study. The analysis of comparative performance shows that the enhancement of combustion stability is important and optimized fuel injection can lead to a better use of fuel and a less harmful impact on the environment. There are also advanced technologies of emission control, like lean combustion and staged fuel injection. The results are used to come up with more sustainable propulsion technology in future aviation systems.
