Approximately one-third of the energy supplied to the cylinder of an internal combustion engine is transformed into effective work, while the remaining energy is dissipated in multiple ways. Offering solutions that can recuperate some of the energy the engine wastes is important and beneficial. This research examines how the timing of injection start influences the ability to reclaim waste heat in a reactive control compression ignition engine. Following the validation, the diesel fuel injection timing was adjusted. Their effects on exergy destruction, productivity coefficient, engine output power, and produced pollutants have been studied. The results showed that by advancing the start time of fuel injection, parameters such as the efficiency of the first law of thermodynamics and pollutants such as unburned hydrocarbons and carbon monoxide increased and decreased, respectively. In addition, the exergy resulting from the heat transfer has increased due to the high heat transfer due to the high temperature of the load inside the cylinder. Therefore, the high temperature has caused the irreversibility to increase due to the increase in the number of chemical reactions. The efficiency of the system increased with advanced fuel injection start time.
