降低柴油机排放和燃油耗的技术

降低柴油机有害排放物的技术是一系统工程,其中最为重要的是对燃烧过程的优化.改善燃油喷射系统和涡流比,应用多气门机构.排气再循环、电控技术、增压中冷技术,减少润滑油的窜漏燃烧等都有利于燃烧的优化.改善燃油的品质,应用颗粒捕集器和催化氧化器等机外净化措施也是减少排放的重要手段.

Diesel emission control technique is a system engineering. The most efficient way is the improvement of combustion process. It is beneficial to combustion process to improve injection system and swirl ratio, to use multiple valve mechanism, exhaust gas recirculation, electronic control technique, and intercooled turbocharger and to reduce oil leakage. Improve fuel quality and the outer engine emission control such as particulate trap system and catalytic oxidation is the important emission control measure.
