The invention relates to the technical field of engine equipment, and discloses an unmanned aerial vehicle engine with a heating component, the unmanned aerial vehicle engine comprises a
crankcase and a plurality of cylinder bodies fixed on the two sides of the
crankcase, an air
inlet channel is fixed on the
crankcase, a
crankshaft is rotatably installed in the crankcase, the central axis of the
crankshaft is perpendicular to the central axis of the cylinder bodies, and the heating component is fixed on the cylinder bodies. A
piston is arranged in each cylinder body in a sliding mode, and a connecting rod is rotationally connected between the
piston and the
crankshaft; a ventilation channel and an exhaust channel are arranged on the side wall of the cylinder body, the ventilation channel is communicated with the interior of the crankcase, and a heating
assembly with one end extending into the ventilation channel is fixed to the cylinder body. The heating
assembly comprises a connecting shell and a heat conduction rod fixed in the connecting shell. The heat conduction rod extends into the ventilation channel to preheat gas entering the cylinder body, so that
fuel oil can be fully atomized to facilitate ignition, and an engine can be easily started in a low-temperature environment.
