柴油机能否顺利启动,关键在于喷入气缸的柴油能否与被压缩的空气迅速形成可燃混合气并及时着火燃烧,因此,要求进入气缸的空气被压缩后有较高的温度和压力。启动的基本条件:要有足够的启动转速,启动转速高气体渗漏少,压缩空气向气缸壁传热的时间短、热量损失少,可以提高压缩终了时空气的温度和压力;气缸密封性要好,启动时气体渗漏少, The key to whether the diesel engine can start smoothly is whether the diesel fuel injected into the cylinder can rapidly form a combustible mixture with the compressed air and promptly ignite and burn. Therefore, it is required that the air entering the cylinder be compressed and have higher temperature and pressure. Start the basic conditions: to have a sufficient start-up speed, start the high speed gas leakage, compressed air to the cylinder wall heat transfer time is short, less heat loss, can improve the compression end of the air temperature and pressure; cylinder sealing better , Start gas leakage less,
