The invention provides an adjustable engine air inlet system. The adjustable engine air inlet system comprises an air filter, an air inlet clean tube, a first air inlet dirty tube, a second air inlet dirty tube, a third air inlet dirty tube and a three-way control cavity, wherein an air inlet of the air filter is communicated with the air outlet end of the first dirty air inlet tube, an air outlet of the air filter is communicated with the air inlet end of the clean air inlet tube, and the air outlet end of the clean air inlet tube is communicated with an air inlet manifold of the engine. The air inlet end of the first air inlet dirty tube is communicated with the air outlet of the three-way control cavity, the first air inlet of the three-way control cavity is communicated with the second air inlet dirty tube, and the second air inlet of the three-way control cavity is communicated with the third air inlet dirty tube. The length of the second dirty air inlet tube is smaller than that of the third dirty air i
