Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] Such as figure 1 , 2 shown.

[0019] A kind of four-stroke small gasoline engine, comprises body 7, and body 7 can be made up of upper and lower two parts, is provided with oil storage chamber 14, cylinder 9, crankcase 2 in body 7, and cylinder 9 is positioned at the upper half of body 7, and crankcase 2 and Cylinder 9 communicates with and is located at the lower part of body 7. Oil storage chamber 14 is located at one side of cylinder 9 and crankcase 2. The lower part of crankcase 2 is provided with oil outlet 3, and the lubricating oil mist discharged from oil outlet 3 passes through the oil outlet. Channel 4 (see figure 1 ) enters the valve control chamber 6, and is separated from the oil return passage 15 (see figure 2 ) into the oil return channel 1 communicating with the oil storage chamber 14 to complete a cycle and be reused. An oi...

Abstract

The invention relates to an arbitrary turnover four-stroke engine which comprises a diaphragm type carburetor and a fuel storage chamber, wherein the diaphragm type carburetor is used for pumping fuel by means of pressure pulse of a crank case of the engine and circulating redundant fuel to a fuel tank; the fuel storage chamber is used for sealing and storing lubricating oil and is internally provided with an oil-mist generator; a crank shaft drives the oil-mist generator to generate lubricating oil mist; an inlet channel on an air cylinder wall is communicated with the fuel storage chamber; a fuel outlet channel on the crankshaft case is communicated with an air valve control chamber; an air valve control device and an oil and gas separation device are mounted in the air valve control chamber; the upper part of the air valve control chamber is communicated with air through a fuel filter, and the lower part of the air valve control chamber is connected with the fuel storage chamber through a fuel return channel. The invention solves the difficult problem of arbitrary turnover in the four-stroke engine, improves the lubricating effect and eliminates the phenomenon of cylinder scoring and engine oil injection in the prior engine.

Description

technical field [0001] The invention relates to an engine, in particular to a four-stroke engine used on a small hand-held device, in particular to a reversible four-stroke engine. Background technique [0002] At present, a large number of hand-held tools are used in agriculture, forestry, animal husbandry, gardens, households and other industries. Among them, the mechanical equipment powered by gasoline engines occupies a large market. Due to the simple structure of the two-stroke engine, it can output power in any flipped state. And ordinary four-stroke engine lubricating system can't work under the overturned state, so on hand-held power tool and some agriculture, forestry, military equipment, still use two-stroke engine in a large number. [0003] Since the two-stroke engine has no independent intake and exhaust strokes, the scavenging and intake and exhaust processes overlap, and the mixed combustion of engine oil and gasoline results in high pollution and high fuel co...
