Of diesel engine electronic control type governor

摘要

PURPOSE:To quickly stop an engine by stopping the action of a control action unit with the stop operation of an action unit stop operation unit, operating an engine stop operation unit, and moving a metering rack to the stop position via a balance spring. CONSTITUTION:For the engine stop, the action of a control action unit 4 is stopped by the action of an action unit stop operation unit 8 via an injection quantity control device 5, an engine stop operation unit 11 is operated, and a metering rack 2 is operated to the engine stop position together with the tension Fs of a balance spring 3. For operation, the rack position of the metering rack 2 is set by the balance between the action force of the control action unit 4 and the balance spring 3. The spring action region 14 of the bal ance spring 3 is set to the size equal to or slightly larger than the rack metering action region L1 of the metering rack 2, thus the driving resistance force of the metering rack 2 is relatively decreased proportionally as the change rate of the spring tension is increased. The metering control precision of the metering rack is increased, and the engine can be quickly stopped.
