This experimental study mainly focused on investigation of the performance of diesel engine using palm oil methyl ester (POME). The engine operating conditions such as optimized IT of 27°BTDC and varied IOP with nozzle geometry and combustion chamber shapes were investigated. The better operating conditions of combustion chamber shape and nozzle geometry were reported. The operating conditions of the engine were maintained 1500 rpm and CR of 17.5. For diesel engine operation with POME, it could be revealed that IT of 27°BTDC, IOP of 240 bar, 5 holes nozzle geometry with Torroidal Re-entrant combustion chamber (TRCC) gives more improvement in brake thermal efficiency (BTE) with minimum emissions.

This experimental study mainly focused on the investigation of CRDI diesel engine powered with palm oil methyl ester (POME) biodiesel and diesel fuels. The Toroidal Re-entrant combustion chamber shape (TRCC) and 6 holes CRDI injector were selected for experiment. The current research engine operated with constant CR 17.5 and speed 1500 rpm. In the first phase of work, the injection timing (IT) varied from-25 °BTDC to 5 °ATDC with interval of 5 degree during the experiments. The injection time-10 °BTDC has been optimized for higher engine efficiency. In the second phase of work, the injection opening pressure (IOP) has been varied form 600 bar to 1000 bar with increment of 100 bar interval during the experiments. The IOP of 900 bar has been optimized with constant fuel IT-10 °BTDC. Finally, the end results of experiments were reported that combined effects of IT (-10 °BTDC) and IOP (900 bar) enhanced the engine output in terms of brake thermal efficiency (BTE), also minimizing the pollutants using TRCC shape and 6-hole CRDI injector for CRDI diesel engine at 80% load.
