(一)前言柴油机的燃油通过供油系统的喷射装置喷入燃烧室,以便形成适合于燃烧的混合气体。燃油的喷射过程是否适当,对柴油机的燃烧以及由此所引起的经济性能、热负荷和机械负荷等的影响很大。高效率的燃烧要求合适的喷油定时和喷油规律,并必须有足够的喷射压力使雾化良好和贯穿度适当。在一般由喷油泵、高压油管和闭式喷油器所组成的喷射装置中所进行
(A) Foreword Diesel fuel is injected into the combustion chamber through the injection device of the fuel supply system to form a gas mixture suitable for combustion. Whether the fuel injection process is appropriate, the combustion of diesel engines and the resulting economic performance, heat load and mechanical load, etc. have a great impact. High-efficiency combustion requires proper injection timing and injection laws and must have sufficient injection pressure to provide good atomization and proper penetration. In the general by the injection pump, high-pressure tubing and closed injection device consisting of injection device
