Abstract
Experiments were performed on a diesel engine with varying injector opening pressure (IOP) and fuel injection timing of 45° before top dead center. Hydroxy gas was mixed with incoming air at a constant flow rate of 200 ml/min. An increase in IOP improved brake power and brake thermal efficiency (BTE) by 8.42% and 7.03%, respectively. The addition of hydroxy gas improved brake-specific fuel consumption, brake power, and BTE was 7.10%, 3.2%, and 11.48%, respectively with increment in IOP. Carbon monoxide, hydro carbons, and smoke were reduced by 29.24%, 19.84%, and 32.27%, respectively due to hydroxy gas addition at elevated IOP.
