None of the engine governors should return force to the initial equilibrium position
To reduce the engine speed, pull the load handle in the direction of the oil reduction. The amount of oil is reduced and the engine speed is reduced until the oil level is matched to the load. On the surface, it seems that the RAD two-pole and RSV full-speed governors have exactly the same speed-adjusting actions, but they are very different. The difference is that the spring pre-tightening force of the RAD governor is large enough, so there is no automatic speed regulation after the handle of the wrench, that is, there is no dynamic balance between the centrifugal force of the flying block and the governor spring force for the positioning of the sliding sleeve. It can be seen that, in the case of constant engine load, the process of changing the rotation speed is started from the oil volume until the oil volume and load are adapted. Therefore, the RAD governor is a two-pole governor because it only performs automatic control within the idle and high speed regulation range and does not function within the medium speed range. Under balanced conditions, no matter what kind of external load the engine is subjected to, there should be no force that should be returned to the initial equilibrium position of the engine governor besides changing the load handle. Compared with RSV, the most significant advantage of RAD governor is that the operating force when using the load handle to increase the speed is very small, which is more suitable for road transport vehicles. When starting and idle speed control of the diesel engine is stopped, the flying block is closed inward under the action of a starting spring, an idle speed spring and a governor spring. In this case, if the load handle is moved to the full load (in contact with the large throttle stopper) position, the rack bar moves to the position where it exceeds the full load to reach the maximum start enrichment level. At this time, if the injection pump or governor is equipped with a rack stopper, the rack bar will move to the stopper (or compress the thickening spring) position.
