The invention provides a jitter suppression method for an engine. The jitter suppression method comprises the following steps: constructing a delay function and a pulse torque compensation function; a corresponding pulse signal is generated while an ignition signal is generated in each four-stroke cycle; the motor controller starts a monitoring program according to the pulse signal, and the monitoring program generates a pulse compensation instruction according to the delay function and the pulse torque compensation function; and in each four-stroke cycle, the motor controller controls a motor to execute the torque adjustment value corresponding to the pulse compensation instruction according to the pulse compensation instruction and the whole vehicle instruction. According to the method, the jitter time of the engine in each four-stroke period is determined by constructing the delay function, and the torque compensation amplitude of the jitter of the engine is determined by constructing the pulse torque compensation function, so that the jitter of the engine in each four-stroke period can be inhibited and adjusted in time.
