The invention discloses a multi-fuel charge compression ignition engine combustion system and a control method, and relates to the technical field of internal combustion engines. The multi-fuel chargecompression ignition engine combustion system comprises a combustion chamber, a sensing system, a controller and an injection system, and is characterized in that the injection system is configured to be used for injecting at least two fuels to the combustion chamber so as to form a mixed gas in the combustion chamber; and the controller is configured to be used for controlling the injection system to inject the at least two fuels, so that the mixed gas in the combustion chamber forms concentration and activity layering, and the ICCI-mode combustion is carried out in the combustion chamber. Through implementing the multi-fuel charge compression ignition engine combustion system and the control method provided by the invention, concentration and activity layering of the mixed gas in the cylinder can be flexibly re
