Method and system for power control of car-mounted diesel engine

Abstract

Abstract PURPOSE:To lessen speed change control frequency in time of climbing the uphill grade and to make it easier, by installing a controller and control rack regulator to control a fuel pump according to signals from the engine speed detector and speed gear control position detector. CONSTITUTION:A control rack regulator 2 and a governor 7 both are installed on a fuel-injection pump 1. An engine speed detector 4 and a speed change control position detector 5 are connected en bloc to a controller 3. When the engine is in full-load running and not yet in a specified gear step, a full-load torque curve is Co. During climbing the uphill grade with a designated gear step by the speed gear, when engine speed gets lowering down, the signal of the control position detector 5 enters the controller 3, forcing the control rack into the fuel increment direction. In this condition, only when an accelerating pedal is treadled, engine's generating torque becomes increased and a shifting of the speed gear for climbing the uphill grade is thus made unnecessary.
