“…The re-entrant piston bowl geometry gives better results at full load than the other two piston bowl geometry. At 75% load, the toroidal piston bowl geometry shows the least emission, which concludes that the modi cation in the piston bowl geometry gives better results than the standard geometry [29][30][31][32]. Opacity is maximum at full load for D-50 o C RPBG and is lowest for D-50 o C HPBG.…”

“…The same trend is observed for the CI20 blend preheated in comparison to the CI20 blend without preheating. The study outcomes show that the emission of CO for biodiesel blends is slightly lesser than conventional diesel [29][30][31][32]. respectively.…”

“…This might be due to the carbon content present in the fuel that has to be oxidized to CO 2 . So it is clear that there are no considerable changes in the CO 2 emission using different PBGs [29][30][31][32].…”

“…It indicates the BSFC of preheated CI20 fuel has less for TPBG than to other blends and geometry. Due to improved atomization and better fuel was mixing for preheated fuels resulting in the decreased BSFC [29][30][31][32]. The variation of CO emission with and without preheating for different PBGs are depicted in Figure 14 helps in the reduction of emission of CO.…”

“…It is highest for diesel re-entrant piston bowl geometry (D-RPBG), but overall it is seen that the biodiesel blends have less Opacity when compared to the diesel blends. Thus, giving better emission characteristics [29][30][31][32].…”

The present investigation is carried out on biodiesel practicability over the existing non-renewable fuel due to its environmental dilapidation effect and oil crisis. Biodiesel was extracted from crude oil by transesterification, and its properties have been compared with those of neat diesel according to ASTM standards. Then, the blends of biodiesel are prepared for experimental analysis. Experimental results from our previous research study, the best blend was optimized. Then, the standard CI engine with Hemispherical Piston Bowl Geometry (HPBG) is modified to Toroidal or Split type Piston Bowl Geometry (TPBG) and Re-Entrant Piston Bowl Geometry (RPBG). Experimental works were carried out for preheated optimized blend, neat diesel with modified Piston Bowl Geometries. The engine characteristics results were compared with these altered conditions. The modified PBG with preheated biodiesel blend resulted in better Performance and Combustion characteristics. The preheated biodiesel blends indicated significant depletion in the emission of harmful particulate matter such as CO, NOx, and unburnt Hydrocarbons.

This study uses AVL FIRE 2020 R1 software for simulation and experimental verification to deeply analyze the impact of combustion chamber geometry and biodiesel on diesel engine performance at different injection timings. The study found that: With the advancement of injection timing, the indicated fuel consumption rate, cylinder pressure and NOx emissions of the two combustion systems increased, while the indicated thermal efficiency, temperature and Soot emissions decreased accordingly; The blending of low calorific value biodiesel will increase the indicated fuel consumption rate of the two combustion systems, but at the same time it can effectively reduce NOx and Soot emissions; The T: Turbocharger, C: Charger air cooling, D: Diesel particle filter (TCD) combustion system improves the utilization rate of cylinder air due to its unique combustion chamber geometry, thereby improving combustion performance. Compared with the Omega combustion system, the indicated thermal efficiency of the TCD combustion system increased by 6.16% to 8.38% and the indicated fuel consumption rate decreased by 5.80% to 7.73% when burning four types of fuel. In addition, the in‐cylinder pressure and temperature increased, and it performed better in reducing Soot emissions. The research results show that the TCD combustion system can effectively improve the combustion and emission performance of diesel engines, provide data support for the development of diesel engine combustion systems and the combustion of oxygen‐containing fuels in plateau environments, and provide an important reference for energy conservation and emission reduction.
