Embodiment Construction

[0014] Such as figure 1 and figure 2 As shown, a two-stroke small gasoline engine oil and gasoline oil supply system is mainly composed of a fuel tank 3, a carburetor 4 and an intake branch pipe 8. An oil box 2 is installed on the casing 1 of the gasoline engine, and the oil box 2 An oil-cutting automatic flameout mechanism 11 is set inside, the oil box 2 communicates with the intake branch pipe 8 through the oil pipe 5, a self-priming check valve 6 and a flow regulating valve 7 are arranged on the oil pipe 5, and the outlet of the oil pipe 5 is set A negative pressure nozzle 9 communicates with the intake branch pipe 8, and an on-off valve is arranged between the flow regulating valve 7 and the negative pressure nozzle 9 on the oil pipe 5 .

[0015] The working principle of the oil supply system of the present invention is that after the engine of the two-stroke small gasoline engine is started, under the action of suction generated by the engine, the oil in the oil box 2 p...

Abstract

An engine oil and gasoline separate supply system for small two-stroke gasoline engines mainly comprises an oil tank, a carburetor and an intake branch pipe. An engine oil box is mounted a housing of a gasoline engine and communicated with the intake branch pipe through an engine oil pipe. A self-priming one-way valve and a flow regulating valve are disposed on the engine oil pipe. A negative pressure nozzle is disposed at an outlet of the engine oil pipe and communicated with the intake branch pipe. An engine oil inflow mechanism communicated with the intake branch pipe is added to an existing oil supply structure, engine oil and gasoline are automatically metered and mixed by suction generated by the small two-stroke gasoline engine started, oil supply for the existing small gasoline engine is greatly facilitated, and the engine oil and gasoline separate supply system has the advantages of simple structure, convenience in use and accuracy in metering.

Description

technical field [0001] The invention relates to an engine oil supply system, in particular to a two-stroke small gasoline engine oil and gasoline oil supply system. Background technique [0002] General-purpose small gasoline engines are mainly used as supporting power for agricultural and forestry plant protection machinery, small agricultural machinery, garden machinery, generator sets, construction machinery, outboard machinery, etc. Because of its small size, light weight, cheap price, and convenient use, it occupies an important position in various machine tools, especially in knapsack machines, and the general-purpose small gasoline engine is the only supporting power. [0003] General-purpose small gasoline engines are divided into four-stroke and two-stroke. The two-stroke gasoline engine has the advantages of large power per liter, good uniformity of torque, stable operation, simple structure and convenient portability. The oil supply system of the existing two-st...
