introduction： Hefei electromagnetic clutch for you to introduce the relevant knowledge of the throttle。 A throttle is a controlled valve used to control the flow of air into the engine，It goes into the intake pipe and mixes with gasoline(Different models of cars，Design mixing parts are different)，Becomes a flammable gas mixture，Participate in combustion and do work。Four-stroke gasoline engines are generally like this。 Throttle is the most important part of the engine system of todays electric injector，On top of him is an air filter，Lower start Cylinder block，Its the throat of the car engine。Whether the car accelerates flexibly，It is very related to the cleaning of the throttle valve。And the throttle should not be removed
