Vehicle post-processing method and device, computer equipment and storage medium

The invention provides a vehicle post-processing method and device, computer equipment and a storage medium. The vehicle post-processing method comprises the steps that the first temperature in the vehicle post-processing process is monitored; the vehicle post-treatment comprises purification treatment on vehicle emissions; when the first temperature is within the preset temperature range, calculating a target correction value of an oil injection combustion parameter of the vehicle engine at the first temperature; and oil injection combustion parameters of the vehicle engine are corrected based on the target correction value. According to the embodiment of the invention, when the first temperature of the vehicle after-treatment is within the preset temperature range, the fuel injection combustion parameter of the vehicle engine is adjusted, so that the original emission level can be reduced, the conversion efficiency of emissions can be improved, the emission control effect can be improved, and the emission c
