近年,农用、工业用及车用小型柴油机对降低噪声提出了更高要求。由于考虑到环境问题,排放要求变得更加严格。 为了满足这些目标,需要改进柴油机燃烧。特别是,燃料喷射系统是控制发动机燃烧的关键部件,希望其应有戏剧性的改进。 本研究要追求理想的燃料喷射系统,以实现柴油机的最佳燃烧,从而取得低的燃烧噪声和清洁的排放。本文将介绍燃料喷射技术包括喷射压力型式、喷射率型式、喷射定时和喷雾型式等方面的最新进展。 In recent years, small diesel engines for agricultural, industrial and vehicular applications have placed higher demands on noise reduction. Due to environmental issues, emission requirements have become more stringent. In order to meet these goals, there is a need to improve diesel combustion. In particular, the fuel injection system is a key component in controlling engine combustion, and it is hoped that it should be dramatically improved. This study pursues the ideal fuel injection system to achieve the best combustion of the diesel engine, resulting in low combustion noise and clean emissions. This article describes the latest advances in fuel injection technologies including injection pressure patterns, injection rate patterns, injection timing, and spray patterns.
