The sound insulation modification of the Micro Blue 6 plug-in hybrid engine can be carried out according to the following steps:
1. Prepare sound insulation materials
Choose professional sound insulation materials, such as black self-adhesive sound insulation cotton, white self-adhesive sound-absorbing cotton, shock absorbers, etc., or Great White Shark series sound insulation materials, Russian STP sound insulation and Russian Smart sound insulation materials, etc.
2. Engine compartment sound insulation treatment
Remove the sound insulation cotton from the original engine compartment cover. If the thickness of the original sound insulation cotton is still acceptable, you can add a layer of anti vibration sticker and a layer of black sound insulation cotton on top of it.
The cavity next to the windshield of the hood can be filled with white sound-absorbing cotton to enhance the sound insulation effect.
It is also possible to perform sound insulation treatment on the cavities of the two fenders and the front wheel hub, such as using anti vibration stickers and sound-absorbing cotton materials.
3. Sound insulation treatment for other parts
Car door: Double layered anti vibration treatment is applied to the car door, using sound insulation materials such as silver shark glue and black gold to form a box with the door panel, preventing wind noise from entering.
Pedal position: This is the main path for various noises to enter the engine compartment. Anti vibration materials such as Golden Shark JS300 can be used for anti vibration treatment, and soundproof pads and sound-absorbing materials such as Jingjing No.1 can be used for sound insulation and absorption treatment.
Fenders: In order to prevent the transmission of road noise and tire noise, the fenders can be treated with double-layer anti vibration materials and sound insulation materials.
Through the above steps, the sound insulation effect of the Micro Blue 6 plug-in hybrid version can be significantly improved, creating a quieter and more comfortable driving environment for drivers.
