The invention discloses a series mode combustion efficiency control method for a hybrid electric vehicle and a storage medium. When the whole vehicle is in a high-temperature series control mode, thetarget output power is kept unchanged, and the engine speed is increased and the engine output torque is reduced, so that the combustion efficiency reaches the optimal combustion efficiency under thecurrent working condition. The knocking phenomenon of the engine is eliminated by increasing the rotating speed of the engine and reducing the output torque of the engine, so that the combustion efficiency of the engine reaches the optimal combustion efficiency under the current working condition, the output power is kept unchanged, the knocking phenomenon of the engine is eliminated, and deterioration of fuel economy is avoided.

The magnetic damper mechanism is configured to generate a resilient force when a relative displacement is produced between the first and second rotary members and the third rotary member in a rotational direction, the resilient force serving to reduce the relative displacement.

The long-term constraint on the design structure principle of an internal combustion engine transmission conversion mechanism is broken through, two sets of pistons, gears and racks are symmetrically arranged to form linkage assemblies, the two linkage assemblies form a coupling relation with the 90-degree phase difference, and the two coupling assemblies alternately do work and are overlapped for shift connection. The racks which are disengaged during operation of the mechanism are thoroughly separated from a load, and the racks are clamped at the corresponding positions of piston stop points under the cooperation of the gears and lock a re-entering tooth entry point; and the disengaged gears are driven by the coupling assemblies, rotate to the entry point along a set restriction track of the racks, and are integrated to be engaged again. Through locking of the racks, constant-volume combustion, constant-volume interval computer tracking and timely ignition are created, and coupling meshing with synchronous rack speed is achieved. According to an improved internal combustion engine, the alternating side pressure of a crankshaft dead point and the pistons on the pipe wall is eliminated, loss is reduced, vibration is reduced, the conversion efficiency of working medium gas is improved, combustion is thorough, pollution is reduced, the environment is protected, and power and performance are greatly improved.
