The invention provides a fuel field mixing compression ignition internal combustion engine and a control method thereof, in particular relates to fuel preparation, supply and combustion control of a combustion engine. The invention adopts a high-octane and high-cetane fuel field mixing and auxiliary ignition technology, and can meet the requirement that the internal combustion engine makes use of the fuel of different octane numbers under different loads, namely, more high-cetane fuel is mixed in the high-octane fuel under low load or ignition is assisted in, to improve the ignition property of the mixed fuel so that the mixed fuel can be fired reliably under low load and temperature with the firing time controllable. The quantity of high-cetane fuel to be mixed in is reduced under medium load; a signal high-octane fuel is adopted under large load to avoid engine detonation. By adopting the fuel field mixing compression ignition combustion mode, not only an even premixing compression ignition engine is prevented from being on fire under low load, but also the working condition range under large load can be widened. In addition, the power performance of the engine is improved. In this way, the even premixing compression ignition engine is practical.
