<br/><br/> This study investigates the challenges and techniques associated with the extraction of<br/>stuck fuel injectors from diesel engines. Sticking or seized fuel injectors can impede engine<br/>performance, fuel efficiency, and overall functionality. The research focuses on analyzing<br/>common causes of injector seizure, ranging from carbon deposits to corrosion, and explores<br/>practical approaches for successful removal. The results of hydraulic puller were obtained<br/>by comparative analysis between numerous tests. Throughout the process, the data changes<br/>from trial to trial. All data collected showed how the project worked effectively and<br/>efficiently. The testing of two fuel injector removal methods, namely the hydraulic puller<br/>and the impact fuel injector puller, revealed distinct characteristics. The hydraulic puller<br/>method consistently generated pressure around 500 psi and demonstrated quick and<br/>relatively consistent removal times, ranging from 4 to 6 seconds. On the other hand, the<br/>impact puller, operated manually, exhibited more variability in removal times, spanning<br/>from 14 seconds 58 seconds, with no specific information provided about the generated<br/>pressure. These findings suggest that the hydraulic puller method offers a quicker and more<br/>consistent removal process compared to the impact puller method, indicating potential<br/>differences in efficiency and performance between the two tools. The evaluation results<br/>indicate that the hydraulic puller for diesel engine fuel injectors achieved a general<br/>weighted average of 4.53, reflecting high acceptance. This demonstrates strong satisfaction<br/>with the puller’s overall functionality among respondents. Finally, this research study<br/>provides implications and suggestions towards enhancing tools that can be used in the field<br/>of automotive industries.
