The invention relates to a sliding sheet type internal combustion engine. An air compressor is included. A power chamber, an output shaft, a combustion chamber, a high-pressure oil pump and a start motor are further included. The combustion chamber, the air compressor and the start motor are sequentially arranged on the right side of the power chamber. The sliding sheet type internal combustion engine is reasonable in design, the multi-level power chamber is adopted, the waste pressure and the waste temperature are sufficiently utilized, and the heat efficiency is improved. Meanwhile, the combustion chamber and the power chamber are separated, lubricating oil is not needed, the phenomena of cylinder pulling and the like are avoided, and the equipment running stability is improved.
