Background technology
Full Load Characteristics of Diesel Engines line is under the fuel-flow control shift fork position permanence condition for the fuel pump of Fuel Injection Mechanism of Diesel Engine
It obtains, since the speed characteristics line of diesel engine is typically all to rise with rotating speed and be inclined upwardly, when high speed, just slightly turns gentle,
So fuel-flow control shift fork, at small oil mass position, torque and the moment of resistance are once unbalance, the larger fluctuation of speed will be caused；It is another
Aspect when big oil mass position during fuel-flow control shift fork is fixed on, is run in a certain operating mode although diesel engine can be stablized, is born
Slightly reducing for lotus will cause being significantly increased or even causing " driving " for diesel engine speed.It exceeds the speed limit during in order to avoid high speed occur
The phenomenon that " driving " and unstable idle, it is necessary to install governor additional on a diesel engine.
The principle of mechanical governor is that the balance of generated centrifugal force and spring force turns to adjust when being rotated by flyball
Speed, when one timing of throttle position, spring force is certain, and generated centrifugal force is big when rotating speed height then rotates very fast, promotes fuel pump
Plunger position control-rod, reduces fuel delivery, so as to reduce the rotating speed of diesel engine；Diesel engine speed is low, then flyball rotation when institute
The centrifugal force of generation is small, reverses fuel pump plunger position control-rod, and fuel delivery increases, and so as to improve the rotating speed of diesel engine, makes bavin
The rotating speed of oil machine reaches dynamic stabilization；It increases or reduces throttle, actually changed by changing the size of camber of spring
Become spring force so that diesel engine is issued to new balance so as to change the rotating speed of diesel engine in new rotating speed.But common two-stage machine
