In this study, the effect of injection pressure on combustion, performance, and emission characteristics of a diesel engine powered with turbulence inducer piston was studied. Engine tests were executed using conventional diesel and 20% blend of adelfa biodiesel [A20]. The results acquired from renewable fuel A20 in the conventional engine showed reduction in brake thermal efficiency being the result of poor air fuel mixing characteristics and the higher viscosity of the tested fuel. This prompted further research aiming at the improvement of turbulence for better air fuel mixing by a novel turbulence inducer piston [TIP]. The investigation was carried out to study the combined effect of injection pressure and turbulence inducer piston. Considerable improvement in the emission characteristics like hydrocarbon, carbon monoxide, smoke was acheived as a result of optimised injection pressure. Nevertheless, the nitrogen oxide emissions were slightly higher than those of the conventional unmodified engine. The engine with turbulence inducer piston shows the scope for reducing the major pollution and thus ensures environmental safety.
在这项研究中，研究了在带扰流活塞的柴油机中，喷射压力对燃烧、性能和排放特性的影响。使用常规柴油和 20%的阿德法生物柴油 [A20] 进行了发动机试验。在常规发动机中使用可再生燃料 A20 获得的结果表明，制动热效率降低是由于空气燃料混合特性差和测试燃料的较高粘度所致。这促使进一步研究旨在通过新型扰流活塞 [TIP] 改善湍流以实现更好的空气燃料混合。进行了这项研究以研究喷射压力和扰流活塞的综合影响。通过优化喷射压力，在像烃类、一氧化碳、烟雾这样的排放特性方面取得了相当大的改善。然而，氮氧化物的排放略高于常规未修改发动机的排放。带扰流活塞的发动机显示出减少主要污染物的潜力，从而确保了环境安全。
