指出16V240ZJB型柴油机“飞车”的最根本原因是喷油泵控制拉杆失控，致使柴油机供油量远远超出其正常工作所需，出现转数控制死区，造成柴油机转数猛增而“飞车”。然后，探讨了避免柴油机转数控制死区的可行性；介绍一种经济实用、简易可靠的避免“飞车”的“甩缸”专用工具──喷油泵供油齿条钳制防护套筒。 It is pointed out that the most fundamental reason for the 16V240ZJB diesel “flying car” is that the control rod of the fuel pump runs out of control. As a result, the fuel supply of the diesel engine goes far beyond the normal working requirement. Then, the feasibility of avoiding the dead zone of diesel engine speed control was discussed. An economical and practical simple and reliable “Thrust cylinder” special tool to avoid “flying” was introduced.
