Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

Fig. 1 is a flowchart illustrating a method for controlling an engine of a vehicle according to an exemplary embodiment, so as to solve the technical problem in the related art that the NVH performance of the entire vehicle is affected by severe jitter when the engine is shut down. As shown in fig. 1, the method for controlling an engine of a vehicle shown in the present embodiment may include the steps of:

and S11, confirming that the engine is switched to the power-off flameout state from the working state.

And S12, controlling a disc in an air inlet throttle valve of the engine to close for a preset time period.

And S13, controlling the disc in the air inlet throttle valve to reset after the preset time period.

When the engine is shut down, the inertia of the flywheel on the engine is large, and the crankshaft continues to rotate under the inertia of the flywheel, so that the engine may shake violently, therefore, when the present disclosure is implemented, step S11 needs to be executed to confirm that the engine is switched from the working state to the power-off shut-down state. The state of the Engine can be obtained by real-time monitoring of an EMS (Engine management System).

After the engine is switched from the operating state to the power-off flameout state, step S12 is executed to control a disc in an intake throttle valve of the engine to close for a preset time period, and after the disc is closed for the preset time period, the disc is controlled to reset. The preset time period may be 2s, 3s, or 5s, and other time periods, and the disclosure is not particularly limited thereto. For example, when the motor is turned off, the disc is controlled to be closed for 2s and then reset.

Referring to fig. 2, fig. 2 is a schematic structural view of an intake throttle valve according to an exemplary embodiment of the present disclosure. As shown in fig. 2, the intake throttle valve 20 includes an electromagnetic valve 201, an intake duct 202, and a disc 203 disposed in the intake duct 202 and controlled by the electromagnetic valve 201.

Since the disc 203 is controlled by the solenoid valve 201, when it is determined that the engine is switched from the operating state to the power-off state, the solenoid valve 201 can be controlled to continue operating for a preset time period, and the solenoid valve 201 can control the disc 203 to close during the preset time period when the solenoid valve 201 continues operating. After the preset time period, the electromagnetic valve 201 stops working, and the disc 203 resets.

At the moment of flameout of the engine, the disc of the air inlet throttle valve is closed, at the moment, the crankshaft continues to rotate under the action of inertia force of the flywheel, negative pressure is generated at the air inlet end, the negative pressure generates force opposite to the rotation direction of the crankshaft, the crankshaft stops rotating rapidly, and therefore vibration generated at the moment of flameout of the engine when the power is cut off is greatly reduced.

Optionally, with continued reference to fig. 2, the intake throttle valve 20 may further be electrically connected to a delay relay 21, and the delay relay 21 is connected to the solenoid valve 201. Since the delay relay 21 can store a part of the electric power, when the engine is turned off, the delay relay 21 can provide the electric power to the solenoid valve 201 to continue to operate for a period of time. The electromagnetic valve 201 in the air intake throttle valve 20 can be controlled to continue working through the time delay relay 21 so that the disc 203 is closed for the preset time period; when the electric energy in the time delay relay 21 is not enough to support the solenoid valve 201 to work, the solenoid valve 201 stops working, and the disc 203 resets.

When the engine is switched from the working state to the power-off flameout state, the disc in the air inlet throttle valve of the engine is controlled to be closed for the preset time period, so that the air inlet end generates negative pressure, the negative pressure generates force opposite to the rotation direction of the crankshaft, the crankshaft can rapidly stop rotating, the vibration generated at the moment of power-off flameout of the engine is greatly reduced, the technical problem that the NVH performance of the whole vehicle is influenced due to severe shaking during engine flameout in the related art is solved, and the NVH performance of the whole vehicle is improved.

It should be noted that the method embodiment shown in fig. 1 is described as a series of acts or combinations for simplicity of description, but it should be understood by those skilled in the art that the present disclosure is not limited by the order of acts or steps described. Further, those skilled in the art will appreciate that the embodiments described in the specification are presently preferred and that no particular act is required in order to implement the disclosure.
