Abstract

The invention discloses a control method for preventing regeneration and sintering of a particle catcher. The method comprises the following steps: acquiring regeneration related parameters of the particle catcher, wherein the regeneration related parameters comprise inlet temperature of an oxidation catalyst, outlet temperature of the oxidation catalyst, outlet temperature of the particle catcher, pressure difference of the particle catcher and air speed of the oxidation catalyst; increasing or decreasing the fuel injection quantity required by regeneration of the particle catcher according to the acquired regeneration related parameters; and injecting fuel according to the adjusted fuel injection quantity. The invention further discloses a control device for preventing regeneration and sintering of the particle catcher.

Description

Technical field

[0001] The invention relates to the technical field of automatic control, and in particular to a control method and device for preventing the regeneration and sintering of a particle trap. Background technique

[0002] With the increasingly serious energy crisis and environmental pollution, people have gradually realized that improving the technical level of diesel engines is one of the most effective and economical means to maintain large-volume, low-cost production of automobiles and solve the dual pressure of environmental protection and energy saving.

[0003] The harmful components of diesel engine exhaust are mainly carbon monoxide (CO), hydrocarbon (HC), nitrogen oxides (NOx), sulfides, particulate matter and odor, etc. Among them, NOx and particulate matter emissions are relatively large, especially particulate matter emissions. It is much higher than other types of vehicles. Tests have shown that diesel engine particulate matter emissions are dozens of time...
