This study investigated the negative impact of exhaust back-pressure (EBP) on diesel engine performance and how it can be mitigated by advancing fuel injection timing (FIT). Experiments were conducted on a diesel engine with various EBP and FIT settings, and the impact of these factors on engine performance was evaluated under a constant load. The results showed that increasing EBP delayed the combustion process, resulted in longer ignition delay periods, and decreased engine efficiency. However, by advancing FIT, these negative effects could be mitigated to some extent. Specifically, advancing FIT led to shorter ignition delay periods, improved combustion rate, and earlier maximum pressure values. The study highlights the potential of controlling FIT as a promising approach to reduce the negative impact of EBP on diesel engine performance and environmental impact. The results of the study have practical implications for diesel engine operators seeking to offset the negative impact of EBP resulting from the integration of waste heat recovery or aftertreatment systems in the exhaust system, which is aimed at improving the efficiency and reducing the environmental footprint of diesel engines.
