| Abstract: | The performance of vehicle diesel engines lies in whether the suited advancer can guarantee that the beginning of burning point occurs at the optimal position before the top dead center. Based on the principle of P type double eccentric pieces advancer of vehicle diesel engines, the software for designing the advancer is written with which the motion of P type double eccentric pieces advancer is simulated. All performance parameters are calculated.The correlation of structure parameters of the advancer, and that of the spring force with the advanced angle are analyzed respectively,along with the machine choke phenomenon frequently occurring during the operation of the advancer,thus providing a theoretical basis for the optimum design of the advancer. |
