The air intake heat exchange homogeneous compression ignition engine surrounding the valve is characterized by comprising an air intake valve (4), an oil injection ignition head (5), a precombustion chamber (6), an air intake and exhaust integrated camshaft (8), an exhaust valve (9) and a heat exchange sleeve (13). The exhaust valve (9) is arranged in the middle, the intake valve (4) is arranged in a ring shape, and the intake and exhaust valves are driven by an intake and exhaust integrated camshaft (8). An annular heat exchange sleeve (13) is arranged between the exhaust valve chamber and the intake valve chamber. In the exhaust stroke, high-temperature waste gas passes through the inner side of the heat exchange sleeve (13) to heat the heat exchange sleeve. At the end of the compression stroke, external high-pressure air rushes into the outer side of the heat exchange sleeve (13), is heated and expanded by the heat exchange sleeve, and is sprayed to the cylinder through a nozzle of a heat exchange chamber communicated with the cylinder through the outer side, so that air-fuel mixed gas in the cylinder is subjected to compression ignition. The oil injection ignition head (5) can perform auxiliary oil injection ignition.)
