Mechanical injection Ponpugabana with a torque control device is an electronic control

摘要

PURPOSE: To avoid diffuion of discharge gas, prevent an engine from being damaged and enable to secure the minimum rotation number required for maintaining operation by providing an end stopper above the maximum full-load control path and an end stopper to actuate in the opposite direction below the minimum full-load control path to limit a torque control range. CONSTITUTION: An end stopper 14 is situated a short distance above the maximum full-load control path, and an end stopper 15 is situated a short distance below the minimum full-load control path. Since the lower end stopper 15 is at the closest distance to the minimum full-load control path, it can be effectively used as a reference in resetting a step motor 5 at a specified rotation number Nopt. The step motor 5 can be displaced from this reference point to a desired position X by using an instantaneous control device corresponding to a specified step number by an operation element 6 of it. Next, as a torque control range limited by the end stoppers 14, 15 depends on motor type and output change, the torque control range can be easily expanded/contracted by disc spacers 16', 17.
