[0047] The implementation principle of the high-torque low-noise engine in the embodiment of the application is as follows: when the motorcycle is static, the engine stops working and the internal components of the engine stop running, the metal debris in the engine oil moves downward under the action of gravity and the magnetic force of the first electromagnet 311, and the metal debris is accumulated at the bottom of the temporary storage groove 3121.

[0048] When the motorcycle is started, the first sensor detects that the motorcycle is powered on, sends a signal to the controller, the controller controls the driving member 313 to work, the first electromagnet 311 to be powered off, the driving member 313 drives the scraping strip 314 to slide, the scraping strip 314 slides, the metal debris at the bottom of the temporary storage groove 3121 is abutted by the bottom of the containing groove 3141, so that the metal debris is embedded between the containing groove 3141, the abutment strip 3142 and the bottom of the temporary storage groove 3121. The abutment strip 3142 is separated from the sliding plate 3111, the sliding plate 3111 slides away from the contact switch 315 under the action of the elastic force of the first reset member 3112, the contact switch 315 is opened, the second sensor detects that the contact switch 315 is opened, sends a signal to the controller, the controller controls the second electromagnet 3110 to be powered off, and the closing plate 316 rotates to close the blanking groove 3122 under the action of the elastic force of the second reset member 317. When the other abutment strip 3142 abuts against the other sliding plate 3111, the abutment strip 3142 pushes the sliding plate 3111 to abut against the contact switch 315, the contact switch 315 is closed, the second sensor detects that the contact switch 315 is closed, sends a signal to the controller, the controller controls the second electromagnet 3110 to be powered on, the second electromagnet 3110 drives the magnetic block 319 to move upward, the closing plate 316 is rotated by the pull rope 318, so that the blanking groove 3122 is communicated with the temporary storage groove 3121 and the containing groove 3141, the metal debris in the containing groove 3141 falls into the containing groove 3141 through the blanking groove 3122, and enters the collecting groove 3124 along the cavity wall of the containing cavity 3123 to be collected.
