Problems solved by technology

Because motorcycles sometimes run on slopes or bumpy environments on uneven roads, the position of the fuel outlet of the fuel tank may be lower than that of the carburetor inlet, and the fuel cannot flow into the carburetor by gravity, resulting in lack of Fuel or no fuel can not work normally, resulting in insufficient output power of the engine or shutdown, which affects the normal driving of the motorcycle, and is also a driving safety hazard, posing a greater threat to the safety of motorcycle drivers and passengers

Abstract

The invention discloses all-purpose gasoline machine negative pressure-driven fuel supply installations, including oil mouth out with the fuel tank, carburetor, fuel tube and crankshaft box. Its characteristic lies: there are three ports are installed the fuel pump, the two of which are connected with the fuel pipe, one pipe connecting the fuel ports on the other side of the fuel tank and oil connecting the mouth and the other connecting the port at the other end of the fuel pipe connecting with the carburetor; the third port of Fuel Pump is connected with the vacuum sampling tube linked vacuum tube sampling box connectivity with the crankshaft, sampling box crankshaft pressure changes, control fuel pump on - and closed the invention of the fuel supply installations. According to changes of pressure in Engine box, it automatically guarantee uninterrupted fuel, stability transported to carburetor, the protection of traffic safety; simple structure, installation flexibility. Under the package can be installed with the motor vehicle configuration requirements of the different ways and change its installation location.

Description

technical field [0001] The invention relates to a general gasoline engine fuel supply device, in particular to a general gasoline engine negative pressure driven fuel supply device. Background technique [0002] General-purpose gasoline engines usually burn gasoline to drive the piston to move up and down, and drive the connecting rod, crankshaft, etc. to rotate to generate electricity or obtain transmission torque. Fuel such as gasoline is generally in the fuel tank, enters the carburetor through the fuel pipe, mixes with air, and atomizes to become a combustible mixture. It is converted into mechanical energy to drive the connecting rod, crankshaft, etc. to rotate. There is a threaded hole at the oil outlet position of the lower part of the fuel tank body, and a fuel tank switch is installed to control the conduction and closure of the fuel pipe. The fuel flows into the carburetor from the oil outlet, fuel tank switch, and fuel pipe by gravity. Because motorcycles someti...
