The invention discloses a self-adjustment variable valve control system for a compression ignition engine combusting multiple kinds of fuel. The system comprises a variable valve system, the compression ignition engine capable of combusting multiple kinds of fuel, an inflow air heating device, an ECU, a vibration sensor, an inflow air temperature sensor, an exhaust port position temperature sensor and a rotation speed sensor, wherein the vibration sensor, the inflow air temperature sensor, the exhaust port position temperature sensor and the rotation speed sensor are attached to an air cylinder. The compression ignition engine can combust various fuel including gasoline and diesel. The variable valve system is a double variable valve and can be subjected to stepless control through the ECU within a certain angle range. The ECU collects signals of the sensors, the rough properties of the fuel combusted by the engine can be judged through comprehensive treatment, and then the variable valve system is controlled to make the corresponding control strategy. According to the system, the optimization of the variable valve system control strategy of the compression ignition engine combusting different kinds of fuel can be ensured, and accordingly safe and efficient running of the engine are ensured.
