Problems solved by technology

However, this function needs to meet the characteristics of high DPF intake air temperature, and when the vehicle is driving on urban roads or due to the nature of work that needs to be idling frequently, it is difficult to meet the conditions for active regeneration, resulting in poor DPF regeneration effect and long-term regeneration. The effect is poor, it is easy to cause engine failure, and affect the power and economy of the whole vehicle

Embodiment Construction

[0052] In order to enable those skilled in the art to better understand the technical solution of the present invention, the solution will be further described in detail below in conjunction with specific embodiments.

[0053] In order to meet the requirements of various operating conditions of the vehicle, the vehicle-mounted DPF device can have a regeneration function to improve the performance of the engine and the entire vehicle. Embodiments of the present invention provide a DPF active regeneration method. Refer to figure 1 , which includes the following steps:

[0054] S100: Obtain vehicle driving state parameters;

[0055] S200: According to the acquired driving state parameters of the vehicle, determine whether the driving condition of the vehicle can meet the automatic active regeneration condition; if yes, prepare to start the automatic active regeneration mode; if not, prepare to start the manual active regeneration mode;

[0056] Then according to the different ju...

Abstract

The invention relates to the technical field of engine emissions and discloses a DPF active regeneration method. The DPF active regeneration method includes an automatic active regeneration mode and a manual active regeneration mode. When the vehicle operating condition can meet DPF automatic active regeneration conditions, a vehicle can automatically conduct DPF active regeneration without user operation; when the vehicle is limited by the operating condition and cannot meet the DPF automatic active regeneration conditions, a user manually controls DPF active regeneration to be started for manual active regeneration in the vehicle idle-speed driving state. By means of the DPF active regeneration method, regeneration of a vehicle-mounted DPF under different operating conditions can be achieved, and the working performance and vehicle performance of an engine are improved. The invention further provides a DPF active regeneration control system capable of achieving the DPF active regeneration method. Active regeneration of the vehicle-mounted DPF under the different operating conditions is achieved.

Description

technical field [0001] The invention relates to the technical field of engine emission, in particular to a DPF active regeneration method and a control system thereof. Background technique [0002] Diesel engines are widely used in transportation, construction machinery and other fields due to their good economy, power, reliability and low CO and HC emissions. However, the particulate emission control of diesel engines has not been optimally controlled. At present, diesel vehicles are mostly equipped with DPF (Diesel Particulate Filter, particulate filter) to purify particulate pollutants in diesel engine exhaust. Since the particles in the DPF device will cause the exhaust pressure of the engine to increase, which will affect the power and economy of the vehicle, the particles in the DPF must be treated regularly. This process is called DPF regeneration. [0003] At present, the common DPF regeneration method of the existing diesel engine system is mainly the automatic act...
