The effects of different combustion chamber geometries (PB1, PB2, PB3) and fuel injection pressure (FIP) (500, 750, and 1000 bar) with ternary fuel on diesel engine are discussed. It is observed that an increase in FIP improves brake thermal efficiency and reduces hydrocarbon emissions, while only causing a slight decrease in NOx emissions for PB2. In the case of PB3, NHRR, peak pressure, and ROPR all significantly increase with an enhancement in FIP, indicating an improvement in engine performance and efficiency.
The effects of a diesel engine combustion chamber geometries (PB1, PB2, PB3) and fuel injection pressure (FIP) (500, 750, and 1000 bar) with ternary fuel are discussed in this paper. It is observed that at maximum load as the FIP increased, the PB3 surpasses the PB1 and PB2 in brake thermal efficiency (4.86%) and hydrocarbon (7.2% decrease). However, a minor reduction in NOx (3%) is seen with increased FIP in the PB2. The NHRR (net heat release rate), peak pressure (in-cylinder), and ROPR (rate of pressure increases) all considerably increase with an enhancement in FIP in the case of PB3 by 2.96%, 3.86%, and 1.98%, respectively. It is discovered that altering the fuel injection pressure and piston shape concurrently offers a viable substitute for raising engine output and reducing emissions.
