Summary: In-cylinder pressure-based closed-loop combustion control is a critical technology used to address cylinder-to-cylinder inhomogeneity in modern diesel engines. This study develops a reference governor-based combustion control method to reduce combustion dispersions and calibration effort. The method uses a dynamic-target prediction model and an IMEP control strategy to achieve better transient tracking performance and reduce cylinder-to-cylinder variations.

Summary: This study investigates the effects of fuel injection pressure and injection timing on the performance, combustion, and emissions characteristics of a diesel engine using kar-anja biodiesel with enriched hydrogen. The results show that a blend of KB20H10 at 240 bar injection pressure and 23 degrees CA bTDC injection timing achieves a 4% increase in fuel thermal efficiency compared to diesel. Additionally, the blend exhibits lower emissions of UHC, CO, and smoke opacity, but higher NOx emissions compared to diesel.

Summary: This study investigates and compares the effects of blended fuels with different alcohol substitution ratios on the combustion, performance, and emission characteristics of a diesel engine. The results show that the D80M10B10 blended fuel is the most beneficial in improving cylinder pressure, prolonging ignition delay, and shortening combustion duration. Additionally, the addition of alcohol fuels reduces soot, HC, and CO emissions, but increases NOx emissions.

Summary: The cetane number significantly affects the combustion and emissions of diesel engines. As the cetane number increases, the peak in-cylinder pressure and heat release rate decrease, while the coupling injection pressure, NOx emissions, and the number concentration and total mass of particulate matter increase.

Summary: A series of experiments were conducted to investigate the combustion, emissions characteristics, and fuel consumption of a diesel engine equipped with an elliptical nozzle. The results showed that the elliptical nozzle had shorter ignition delays, lower maximum rates of heat release, and longer combustion durations. Under different loads, the elliptical nozzle reduced NOx emissions to some extent, but increased soot emissions. Furthermore, when coupled with moderate earlier fuel injection, the elliptical nozzle significantly improved the trade-off between fuel consumption and NOx emissions.

Summary: The study demonstrates the potential for improving the trade-off between fuel consumption and tailpipe NOx emissions through VEC in both conventional vehicles and HEVs. By utilizing preoptimization and dynamic programming, the optimal trade-off points can be efficiently found. VEC significantly reduces fuel consumption and NOx emissions in conventional vehicles, achieving improvements in both areas.
