| Abstract: | The paper proposed a new method for regulating engine speed through controlling the fuel-stop electromagnetic valve during gear shift,analyzed its influence on engine′s performance,worked out its control strategy and carried out experiments on a model of heavy truck equipped with automated mechanical transmission(AMT).The experimental results show that the method can reduce the rotational speed difference between driving part and driven part when the clutch is engaged,thus improving the shift quality of AMT. |

| Keywords: | fuel-stop electromagnetic valve shift quality automated mechanical transmission(AMT) |
