| Abstract: | The regression analysis method was adopted to build mathematical models about the power and torque relative to rotation speed of daul-fuel engine based on velocity characteristic test results.The decisive coefficients of these models exceeded 0.99.Some technical parameters such as the variational rate of power and torque,the highest power and its confidence interval,the inflection point and its fastest descent zone of the torque were resulted from the analysis on the models.Finally,the applications of these models were put forward through case study. |
