The invention discloses engine cylinder coating equipment. The engine cylinder coating equipment comprises a conveying device, a coating device and a collecting device; the conveying device is two horizontal and synchronous conveying belts; an engine cylinder is placed on the two conveying belts; the coating device includes a paint inlet pipe, a paint ionization chamber, a high-pressure gas storage cylinder, a spraying gun, an electric shock head and an extension rod; the collecting device includes leakage boxes and a collecting box; the leakage boxes are placed on two sides of the conveying belts; the bottoms of the leakage boxes are inclined to a baking heating area; and the collecting box is positioned below the leakage boxes. According to the engine cylinder coating equipment, the engine cylinder can enable remained materials, leaked before the conveying belts enter the baking heating area, to totally enter the leakage boxes; the remained materials flow into the collecting box through the leakage boxes to prevent dripping on the ground to influence the environmental beauty; and the remained materials can be recycled to save industrial resources.
