Realization method of automatically increasing loading idle speed of engine of engineering vehicle and control system

Abstract

The invention relates to a realization method of automatically increasing a loading idle speed of an engine of an engineering vehicle and an idle speed control system of the engine. The method comprises the following steps: determining a first target rotating speed of the engine in a loading idle speed state, arranging an enabling key on an operating handle of the engineering vehicle, and arranging a controller which is connected with an ECU (Electronic Control Unit) of the engine, the operating handle and the enabling key, wherein the controller controls an electronic control fuel injection system to increase a rotating speed of the engine and keep the engine in the first target rotating speed according to the states of the operating handle and the enabling key when idle load is converted into loading. The control system comprises the electronic control fuel injection system, the controller, the operating handle of the engineering vehicle, two target rotating speed storage units and the enabling key arranged on the operating handle, wherein the controller is connected with the operating handle, the enabling key and the ECU (Electronic Control Unit) of the engine. According to the method and the system, the oil consumption and the carbon emission load of the engineering vehicle can be reduced, and the cost of the engine of the engineering vehicle can be reduced.

Due to the long waiting time before operation of large engineering vehicles, such as fishing tackle and hooks, etc. must be prepared before hoisting of lifting equipment, resulting in a long time for the engine to run at no-load idle speed

The existing engineering vehicles only have one idle speed. In order to meet the needs of engineering operations at idle speed and better reflect the micro-motion performance of the equipment, there is more power margin when selecting and matching the engine, that is, the rated output power of the engine All are greater than the maximum power required by the equipment, and the idle speed of the engine is set relatively high

Therefore, the existing engineering vehicles have the following technical defects: 1. Large fuel consumption, large carbon emissions, no energy saving and environmental protection

2. The engine cost is relatively high

But this control system and method is to use battery to maintain idling state, because the storage capacity of the battery of fuel-powered vehicle is relatively small, so this control system and method are only suitable for ordinary cars with very little load when idling, for engineering vehicles, due to idling The load is heavy, and the engineering vehicle needs to idle for a long time, and the power of the battery cannot maintain its idle state at all.
