EGR machine type regeneration control method and related device

The invention discloses an EGR machine type regeneration control method and a related device. Under the regeneration working condition, the amount of oil to be injected is determined; corresponding cylinders in the first exhaust pipe group are controlled to perform injection based on the to-be-injected oil quantity, and the first exhaust pipe group is controlled to exhaust first waste gas to flow through the turbocharging module; the EGR valve is controlled based on the first opening degree of the EGR valve, and meanwhile second waste gas exhausted by the second exhaust pipe set is controlled to flow through the turbocharging module and third waste gas exhausted by the second exhaust pipe set is controlled to flow through the EGR cooler; the first exhaust gas and the second exhaust gas flowing through the turbine are regenerated based on DOC and DPF. In the process, firstly, the EGR valve is opened at the first opening degree, part of waste gas exhausted by the engine can be subjected to follow-up circulation
