Interactive dashboard exploring engine performance and emissions when running diesel blended with biodiesel, magnetic fuel conditioning, nano-additives, and hydrogen enrichment.

Biodiesel B20 H2 Enrichment Magnetic Fuel Treatment Nano-Additives Emissions Testing

Project Summary

This project, conducted by undergraduate students at Kafr El-Sheikh University's Faculty of Engineering (supervised by Dr. Magda Elfakharany and Prof. Dr. Fawzy Abo Taleb), investigated a low-cost lab test rig to measure diesel engine performance and emissions under different fuel blends: pure diesel, 20% biodiesel (from waste sunflower oil), biodiesel with magnetic fuel conditioning, nano-additive enhanced fuel, and hydrogen-enriched fuel via a PEM electrolyzer cell.

Research Workflow

1️⃣ Build low-cost sensor rig (Arduino + ultrasonic + gas analyzer)
2️⃣ Baseline test with pure diesel
3️⃣ Produce biodiesel from waste sunflower oil
4️⃣ Test 20% biodiesel blend
5️⃣ Add magnetic fuel conditioning + nano-additive
6️⃣ Add H2 via PEM electrolyzer
7️⃣ Add kerosene (7%) to offset rising NOx

Hydrogen Production via PEM Electrolysis

To boost engine efficiency further, the team built a PEM (Polymer Electrolyte Membrane) electrolyzer cell that splits water into hydrogen and oxygen, which is fed into the engine intake alongside the biodiesel blend.

StepReaction
Anode2H₂O → O₂ + 4H⁺ + 4e⁻
Cathode4H⁺ + 4e⁻ → 2H₂

Adding H2 increased engine efficiency but also raised NOx emissions. The team compensated by blending in 7% kerosene, which reduced NOx while maintaining improved efficiency.

3D Interactive Diesel Engine Model (Single Cylinder)

The lab test rig used a single-cylinder, 4-stroke diesel engine coupled to a 6 kVA star-type generator at 1500 RPM — exactly as described in the project [Chapter 1 & 3]. This live 3D model reproduces that configuration, with sliders driving the same variables measured in the study.

Formulas used (from the book, Chapter 3): ṁa = ρ·(π/4)·D²·Va with D = 2.8 cm; η = Pengine / (ṁfuel × Heating Value). Biodiesel % and magnetic current visually affect piston speed and exhaust plume color/intensity to represent the efficiency/NOx trade-off observed in the study.
