Zusammenfassung:	The utility model provides an oil-gas separation device of a filter screen gas-driven engine. The pre-separation device comprises a pre-separation device body arranged in the cylinder head cover. Thepre-separation device is provided with an air inlet hole and an air outlet hole; the cylinder head cover and the pre-separation device are combined to form an oil-gas channel, the pre-separation device comprises a filter screen plate arranged on a bottom plate, a coarse separation device and a fine separation device, the coarse separation device and the fine separation device are arranged on the bottom plate in parallel, the fine separation device is located behind the coarse separation device, and the exhaust hole is formed behind the fine separation device. The filter screen gas-driven engine oil-gas separation device can perform secondary acceleration on an oil-gas mixture, large oil drops and small oil drops are separated respectively and flow out through the oil return cavity, and theseparation efficiency is
