Embodiment
[0021] This embodiment discloses a control system for prohibiting the regeneration of particulate filters for non-road vehicles, including: a carbon load calculation module, a carbon load comparison module, an alarm module, and a regeneration prohibition module. The regeneration prohibition module is activated and can prohibit Particulate filter regeneration, the carbon load calculation module calculates the carbon load in the particulate filter, and the carbon load comparison module compares the carbon load in the particulate filter with the safety threshold set in the vehicle computer Yes, if the carbon load in the particulate filter exceeds the safety threshold, the alarm module will send out an alarm, and the restriction on the regeneration of the particulate filter by the regeneration prohibition module will be lifted manually, and the particulate filter will be regenerated in a safe area.

The embodiment of the invention discloses a non-road vehicle diesel particulate filter regeneration prohibition control system. The system comprises a carbon loading calculation module, a carbon loading comparison module, an alarming module and a regeneration prohibition module, wherein the regeneration prohibition module can prohibit a diesel particulate filter from being re-generated after beingactivated, the carbon loading calculation module is used for calculating the carbon loading amount in the diesel particulate filter, the carbon loading comparison module compares the carbon loading amount in the diesel particulate filter with a safety threshold set in a vehicle computer, if the carbon loading amount in the diesel particulate filter exceeds the safety threshold value, the alarmingmodule sounds an alarm, limiting on regeneration of the diesel particulate filter from the regeneration prohibition module is released, and regeneration of the diesel particulate filter is conductedin a safety area. According to the system, the problem that in the prior art, due to the fact that a non-road vehicle cannot prohibit regeneration of the diesel particulate filter in the working process, the regeneration temperature of the diesel particulate filter is too high so as to be prone to cause a fire is solved.
Description
technical field [0001] The embodiment of the present invention relates to the technical field of automobile control, in particular to a control system for prohibiting the regeneration of a particle filter of a non-road vehicle. Background technique [0002] About 2 million new non-road diesel engines are added every year in the country, and about 20% of the total annual diesel consumption of more than 100 million tons is used for various non-road mobile machinery. These off-road mobile machines are important sources of nitrogen oxide emissions, with a preliminary estimate that they emit more than 2 million tons of nitrogen oxides per year. [0003] Non-road mobile machinery mainly includes excavators, loaders, asphalt pavers, road rollers, bulldozers, forklifts, off-road trucks, etc. The need for pollutant emission control is becoming more and more urgent. In May 2014, the "Limits and Measurement Methods of Exhaust Pollutant Emissions from Diesel Engines for Non-road Machi...
