Abstract
Disclosed is a controller for LPG motorcycle and boosting bicycle (abstract, attached drawing). The utility model comprises five main components, including a reducing valve, a vacuum closing valve, an air door- vent rod synchronous control valve and a cold boot valve body, and four main functional components including a controller valve body, a reducing valve arranged on the controller valve body, a vacuum startup-close valve controlled by the vacuum pumping of an engine and a plunger type air door- vent rod synchronous control valve. Fuel enters the lever type reducing valve and then enters the vacuum closing valve after decompression and pressure stabilization; when the engine starts up, the vacuum startup-close valve turns on and the fuel goes to the air door- vent rod synchronous control valve through the vacuum startup-close valve, thus the air door- vent rod synchronous control valve controls the amount of fuel and air fed to the engine. In the case that the temperature of the engine is too low when the engine is in work, people can turn on a start-up valve to add fuel to the engine. Meanwhile, accessories such as adjusting screws to adjust the amount of the idle air and the fuel gas are arranged on the value body. The controller is suitable to be matched with a 36cc- 250cc two-stroke or four-stroke engine.
