The invention provides an internal combustion locomotive diesel engine unit floating valve vibration isolation installation system and a design method thereof. The installation system comprises a common base, a lower-layer vibration isolator, a middle raft frame, an upper-layer vibration isolator and a diesel generator set which are sequentially arranged from bottom to top. The upper portion of the common base is connected with the lower portion of the lower-layer vibration isolator, the upper portion of the lower-layer vibration isolator is connected with the lower portion of the middle raft frame, the upper portion of the middle raft frame is connected with the lower portion of the upper-layer vibration isolator, and the upper portion of the upper-layer vibration isolator is connected with the lower portion of the diesel generator set. The diesel generator set comprises a diesel engine and a generator, and the diesel engine and the generator are connected through an elastic coupling. The vibration of the diesel engine unit is localized, the vibration comfort of the cab of the diesel locomotive is improved, the vibration input magnitude of equipment on the locomotive is reduced, the reliability is improved, and the service life of the equipment is prolonged.
