| Abstract | ||
| To meet the growing demand for low-emission agricultural machinery, researchers are exploring innovative and sustainable methods to reduce the environmental impact of internal combustion engines and lower greenhouse gas emissions. This study investigates the use of hydrogen as a supplementary fuel in diesel engines, aiming to maximize efficiency and minimize harmful emissions. The experiments were conducted at the Green Power H2O facility, where hydrogen was tested as a complete replacement for diesel fuel in a set of diesel engine pumps. Greenhouse gas emission levels were measured and compared between diesel and hydrogen operation, with strict adherence to safety standards for hydrogen usage. The tests were carried out under engine loads ranging from 30% to 70%. The results demonstrated a successful 100% replacement of diesel with hydrogen. No greenhouse gas emissions—carbon monoxide (CO), carbon dioxide (CO₂), or sulfur dioxide (SO₂)—were detected when using hydrogen. The exhaust gas velocity increased to 4 meters per second with the rise in hydrogen pressure. The water discharge rate reached 56 cubic meters per hour under the same engine load, surpassing that of diesel operation. This research highlights the potential of hydrogen as a clean and efficient alternative fuel, significantly reducing greenhouse gas emissions responsible for global warming while maintaining or even enhancing engine performance. | ||
