["Based on KIVA-3V Program for Variable Parameter Study of Diesel Engines"]
Abstract：["A numerical simulation study on the 1105-type diesel engine was conducted based on the KIVA-3V program. By changing the compression ratio and injection timing angle, the effects on in-cylinder pressure, temperature, NOx, CO, and soot emissions were analyzed. The results show that when the compression ratio increases, the average pressure and temperature peaks inside the cylinder rise, leading to increased NOx emissions and CO generation, while CO and soot emissions decrease. When the injection timing angle varies between 45° and 65°, the average pressure peak first increases and then decreases, reaching its maximum at 60°, while the temperature peak first increases and then stabilizes. NOx emissions increase first and then stabilize with the increase in injection timing angle, reaching the highest at 60°; CO emissions increase with the increase in injection timing angle, reaching the maximum at 65°; soot emissions decrease with the increase in injection timing angle, reaching the lowest at 65°. The research results provide a reference for the improvement and design of internal combustion engines."]
