The search for alternative fuels is driven by increasing environmental and health concerns across the globe. Water-in-diesel emulsions (WiDEs) have been explored over years as a potential fuel diesel engines to mitigate emissions of greenhouse gases, especially nitrogen oxides smoke. Researchers developing testing different formulations emulsified with common goal stabilizing mixture minimizing pollutant without significantly compromising engine performance. In this work, novel approach taken hydrophilic emulsion formulation optimized operating temperatures, overcoming storage-related stability issues that most studies focus on. Two mixtures WiDE were heated supplied Hatz 1B40 single-cylinder engine. was coupled an eddy current dynamometer measure speed, torque, power values. Emissions carbon monoxide (CO), dioxide (CO2), hydrocarbons (HCs), nitric oxide (NO), oxygen (O2) measured AVL DiGas 1000 exhaust gas analyzer. Smoke DiSmoke 480. This study represents contribution field providing experimental evidence formulating temperatures can be advantageous improve thermal efficiency reduce NO smoke at specific conditions, maximum reduction 46.86% 83.67% obtained when compared diesel.

Abstract This study aims to operate a CRDI‐equipped single‐cylinder CI engine in dual fuel mode with pilot‐ignited WCB and port‐injected NH 3 fuel. The current experimentally investigates the influence of various AEFs on performance, combustion, pollutant emissions at peak load (4.14 bar BMEP @ 1500 rpm) conditions constant speed. obtained results showed that AEF was limited due its inherent combustion properties. Under aforementioned operating conditions, we achieved maximum 44.89% AEF. achieves BTE 29.33%. Moreover, operation, switches from diffusion phase operation rapid controlled as increases. ICT reduces 1488 1443 K when increases 0% 44.89%, respectively. Although injection notably decreased CO 2 , HC, CO, smoke by 57.14%, 60.26%, 71.42%, 67.59%, NOx increased 16.21% compared operation. BSEC dual‐fuel is 13.07 MJ/kW‐hr, which slightly higher than biodiesel mode, 12.17 MJ/kW‐hr. ICP, HRR, ID were 2.6 bar, 4.64 J/deg., 5 CAD, CD phasing reduced 9.3 CAD 7.98 However, turbulence within cylinder fluctuates significantly, COV IMEP reaching 5.23% an 44.89%.
