The accelerator pad is highland barley paper.

Green paper is a kind of paper with high mechanical strength, which is used as insulating material. The thickness is 0.1~ 0.3mm. It is dark gray and easy to absorb moisture. Green paper has good mechanical strength, high electrical strength, smooth surface and toughness. It is widely used as insulation material for motors, electrical appliances, meters and other equipment, and also used to make 6250 polyester film composite foil.

Green paper is used as an electrical insulating material for electrical appliances and motors. For example, there is a layer of green shell paper fixed with screws between the fan blade and the fan head of the household ceiling fan; There is green shell paper between the spindle pressure ring and the gear box of the lathe.

Cause of dirty throttle:

Because of the ventilation function of engine crankcase and the function of activated carbon canister solenoid valve, a small amount of gasoline vapor will be brought to the throttle, and the oil and gasoline attached to the throttle will continue to attach to dust.

How long the throttle will be dirty depends on the quality of air filter, engine oil, road conditions, temperature, engine working temperature, driving habits and so on. Dirty oil, long-term non-replacement of air filter and poor quality of air filter will aggravate the dirtiness of throttle valve.
