It is not specifically limited.In one possible implementation, the particular number relationship between the difference and the distributive value, can
It is determined in a manner of using real vehicle calibration.
It is due to caused by combustion knock in view of engine piston thermic load is bigger.Therefore, draw in reduction pinking
While the engine piston thermic load risen is bigger, if combustion knock phenomenon can be eliminated, it can fundamentally solve to start
The bigger problem of machine piston heat load.
In consideration of it, in a kind of possible implementation of the embodiment of the present application, if the acceleration is more than or equal to
Predetermined acceleration threshold value can also adjust injection advance angle other than as described in S102 " control engine nozzle oil spout ".With
The engine in-cylinder combustion situation is adjusted, to eliminate phenomenon of detonation.
In an example of the embodiment of the present application, after adjusting the injection advance angle, pinking can also be obtained again
The acceleration of sensor feedback；With the determination engine whether there is also phenomenon of detonations.If the acceleration obtained again
Degree is less than the predetermined acceleration threshold value, then it represents that after adjustment injection advance angle, the combustion case in engine cylinder restores
Normally, phenomenon of detonation eliminates.At this point it is possible to which controlling the engine nozzle stops oil spout, that is, control the control of engine nozzle
Valve processed is closed.
As can be seen from the above description, the method for control engine nozzle provided by the embodiments of the present application, this method comprises: obtaining
The acceleration of knock sensor feedback is taken, the acceleration is used to characterize the combustion case in engine cylinder；If the acceleration
More than or equal to predetermined acceleration threshold value, engine nozzle oil spout is controlled, to reduce engine piston thermic load.In the application
