Diesel engine air inlet pipe with heating device

The diesel engine air inlet pipe with the heating device comprises an air inlet main pipe, a heating chamber is arranged at one end of the air inlet main pipe, a heating plate is arranged in the heating chamber, an air filter is connected to the outer side of the heating chamber, an outer cover cylinder is arranged outside the air filter in a sleeved mode, and a pipe joint boss is arranged on the outer side wall of the outer cover cylinder. And a plurality of pipe connecting holes in the pipe joint bosses are connected with heat exchange plate pipes through gas guide pipes. When the engine sucks air, external air is sucked along the air inlet hole in the outer end part of the heat exchange plate tube, and as the heat exchange plate tube is fixed on the engine body, air passing through the inside of the heat exchange plate tube is heated by heat generated when the engine works, and the heated air is guided into the outer cover cylinder, so that the heat exchange plate tube is heated. And finally, the gas is sh
