Electrically-controlled engine control method based on smoke intensity limitation

The invention discloses an electrically-controlled engine control method based on smoke intensity limitation. The electrically-controlled engine control method based on smoke intensity control comprises the following steps that a smoke intensity limitation correction MAP is calibrated in advance, wherein the smoke intensity limitation correction MAP includes multiple smoke intensity correction coefficients capable of triggering a smoke intensity limitation oil quantity condition; two control valve opening degree tables are calibrated in advance based on the smoke intensity limitation coefficients; when the acceleration of a vehicle is greater than a first preset acceleration value, the acceleration of an electronic accelerator pedal is greater than a second preset acceleration value, the operating load of an engine is greater than a preset load value and a smoke limitation calculation coefficient obtained by calculation under the current working condition is equal to the smoke intensity limitation correction
