Cylinder internal combustion engine with air bag and high compression ratio

The utility model relates to an internal combustion engine with an air cylinder attached with an air bag and a high compression ratio, which belongs to the field of internal combustion engines and adopts a traditional internal combustion engine structure that a crank of a crankshaft of the internal combustion engine is lengthened and a connecting rod and the air cylinder are synchronously lengthened. When the piston moves upwards to compress sucked air, due to the fact that the compression ratio in the air cylinder is high, large resistance can be generated on the piston, at the moment, part of compressed air can be squeezed into the air bag through the small holes to reduce the resistance of compressed air to the piston, and meanwhile the temperature of the compressed air is reduced; whenthe piston moves downwards to do work, the volume in the air cylinder can be rapidly increased, deflagration gas can be reduced along with the descending pressure of the piston, and when the pressurein the air bag is larger
