PROBLEM TO BE SOLVED: To make self-ignition timing in all combustion chambers proper and provide a stable operation state in a multi-cylinder pre-mixed compression self-ignition engine 100 provided with a plurality of cylinders 3 which form combustion chambers 5 on the inside together with inserted pistons 4, compressing air-fuel mixture of a fuel and a gas, containing oxygen in each combustion chamber 5 and burning air-fuel mixture by making air-fuel mixture self-ignite. SOLUTION: This engine is provided with each of air-fuel mixture temperature adjusting means 23 for adjusting each temperature of air-fuel mixture, before compression in each combustion chamber 5, each self-ignition timing detection means 10 for detecting each of self-ignition timing in each combustion chamber 5 and a control means 12 for making each of the air-fuel mixture temperature adjusting means 23 work, based on a detection result of each self- ignition timing detection means 10 and controlling each self-ignition timing in each combustion chamber 5.
