Detailed description of the invention

Fig. 1 is the process signal of the control method of diesel engine multi gear position constant rotational speed according to an embodiment of the present invention Figure.

Specific embodiment

With reference to the accompanying drawing, specific embodiments of the present invention will be described in detail, it is to be understood that guarantor of the invention Shield range is not limited by the specific implementation.

Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " includes " or its change Changing such as "comprising" or " including " etc. will be understood to comprise stated element or component, and not exclude other members Part or other component parts.

As shown in Figure 1, Fig. 1 is the control method of diesel engine multi gear position constant rotational speed according to an embodiment of the present invention Flow diagram.

A kind of control method of diesel engine multi gear position according to the preferred embodiment of the present invention constant rotational speed, comprising: gear Revolving speed adjustment, the covering of gear revolving speed, gear revolving speed memory storage and constant rotational speed memory function use.It is adjusted and is sent out by throttle Motivation revolving speed is to rotating speed of target value；When engine is run under the mode of constant rotational speed memory function, the rotating speed of target value of throttle When higher than gear revolving speed, covering current gear revolving speed is realized；Engine is adjusted to rotating speed of target value, by inputting memory storage The revolving speed of request signal, present engine is stored in control unit as the rotating speed of target of gear；And in engine start Afterwards, constant rotational speed memory function is activated, the constant rotational speed mode operation of multi gear position is realized by inputting different gear informations.Its In, throttle includes main throttle and secondary throttle；Wherein, gear is 4 gears.
