Problems solved by technology

Since the fuel supply needs to rely on the gasoline pump to extract the gasoline in the fuel tank and deliver it to the carburetor, once the gasoline pump fails or works unstable, the fuel supply will be interrupted and the engine will not work normally.
This oil supply structure through the gasoline pump reduces the reliability of the oil supply system, and due to the use of the gasoline pump, the overall cost of the general gasoline engine is also relatively high

Embodiment Construction

[0015] refer to figure 1 , figure 2 , the fuel supply structure of a general gasoline engine includes a fuel tank 1, a carburetor 2, and an air filter 3. The fuel tank, carburetor, and air filter are all located on the engine side, and the fuel provided by the fuel tank 1 and the air filter 3 provide The fresh air is mixed in the carburetor 2 to form a mixed gas, which is then sent into the engine cylinder to burn and do work to form power. The side of the fuel tank 1 is integrally connected with a fuel tank lug 1a, and the fuel tank lug 1a is provided with a mounting hole. One side of the fuel tank is installed next to the cylinder head 8 through a fuel tank bracket. The fuel tank bracket includes a first bracket 4 and a second bracket 5. The first bracket 4 is fixedly connected to the cylinder head through bolts, and the side of the fuel tank passes through the fuel tank support through bolts. The mounting hole of the ear 1a is tightly connected with the mounting hole on ...

Abstract

The invention relates to a fuel supply structure for general gasoline engines, which comprises a fuel tank, a carburetor and an air filter. The structure is characterized in that one side of the fuel tank is arranged beside a cylinder head through a fuel tank bracket; the lower part of the fuel tank is supported by two support bolts connected with a crankcase body; the carburetor and the air filter are positioned below the fuel tank; one end of a mixed-gas outlet of the carburetor is communicated with an air inlet of the cylinder head through a rigid air inlet pipe; the carburetor is supported by an air inlet pipe; the air filter is connected with the carburetor through a bolt; an air inlet of the carburetor is communicated with the air filter; and an oil inlet of the carburetor is communicated with an oil outlet hole arranged on the bottom of the fuel tank. The invention has the advantages of ensuring compact layout of the fuel supply structure, increasing the overall aesthetic property of gasoline engines, improving fuel supply stability, replacing a gasoline pump with the air inlet pipe, reducing overall cost and improving cost performance.

Description

technical field [0001] The invention relates to the field of general gasoline engines, in particular to a fuel supply structure for general gasoline engines. Background technique [0002] The fuel supply system of the general-purpose gasoline engine of the prior art usually adopts that air filter and carburetor are arranged on the upper side of the engine, the position of the fuel tank is lower than the air filter and carburetor, and the fuel in the fuel tank is provided by a set The gasoline pump is delivered to the carburetor through negative pressure, mixed with the air sent by the air filter to form a mixed gas, and then sent to the engine cylinder to burn and do work to form power. Since the fuel supply needs to rely on the gasoline pump to extract the gasoline in the fuel tank and deliver it to the carburetor, once the gasoline pump fails or works unstable, the fuel supply will be interrupted and the engine will not work normally. This oil supply structure through the...
