Abstract

Abstract: Diesel combustion and emission are directly influenced by the fuel injection, atomization and mixing with air, which also influences the engine performance. Bassed on the conception and spray characteristics of a group-hole nozzle, including spray penetration, spray cone angle and atomization, the effect of a group-hole on the ignition delay, the effect of a group-hole on fuel economy, combustion noise and nitrogen oxides emission were high-lighted and analized. The research results are valuable for the design of the high-performance nozzle.

Key words: diesel engine, group-hole nozzle, combustion
