The engine suspension device with an upward jump limit function is provided with a second limit spring. When the engine body has a tendency to move downward, the first limit spring will give the engine body an upward force, and the second limit spring will give a force to the slider, thereby pushing the first connecting rod to apply an upward force to the engine body. When the engine body has a tendency to jump upward, the limit plate also has a tendency to move upward, thereby tightening the second connecting rod. At this time, the second limit spring is provided to prevent the second connecting rod from moving upward, thereby achieving the effect of upward jump limit, which is convenient for users to use.

[0004] The existing limit jump of the engine is relatively single, and the limit force of the engine jump may be insufficient when driving on poor road conditions, resulting in damage to the car or even traffic accidents, and the limit jump cannot be performed from multiple positions.
