<p>PURPOSE:To avoid the shock in switching operation and improve operability by changing the relation between the operation quantity of the accelerator pedal and throttle opening depending upon to the switching operation of valve operation changing mechanisms. CONSTITUTION:A throttle valve driving means 46 varies the opening of a throttle valve 45 according to the operation quantity of an accelerator pedal. And a control means 43 switches and actuates valve operation changing mechanisms 10a and 10b according to the quantity of the load on an engine. At this time the control means 43 is connected to a throttle valve driving means 46 to change the relation between the operation quantity of an accelerator pedal 47 and throttle opening depending upon the switching work of the valve operation changing mechanisms 10a and 10b. This allows the relation between the accelerator pedal 47 and output torque to become nearly linear for eliminating the torque difference at the time of switching and working of the valve operation changing mechanisms 10a and 10b and avoiding the occurrence of shock at the time of switching and working, which improves operability.</p> |
