Abstract

A fuel-saving device for two-stroke gasoline engine relates to piston type internal combustion engine, especially suitable for air inlet interface device of two-stroke engine used in motorcycle. Many 250 series motorcycles use two stroke gasoline engine, and this engine often takes place to spout in the course of the work, and it is not enough to spout the aeration volume when can making the engine take a breath to influence the improvement of engine power, cause the waste simultaneously, the utility model discloses a design a special valve at the air inlet and solve above-mentioned problem, this valve comprises valve body (1), case (2), spring (3), rand (4), only needs to fix the device at the engine air inlet during the use, allies oneself with the carburetor can. The oil saving rate is at least 12 percent.

Description

Fuel-economizing device for two-stroke gasoline engine

A kind of two-stroke gasoline engine gasoline-saving device relates to internal-combustion piston engine, is specially adapted to the used two-stroke engine intake interface of motorcycle device.

Many 250 series motorcycles use the two-stroke gasoline motor, this motor has characteristic of simple structure, but piston is closed suction port in moving, need certain hour, cause inlet close untimely, make the mixed gas of original suction crankcase, before suction port is not closed fully, fall to spray through Carburetor aditus laryngis, air-strainer from suction port again and go to cause waste, simultaneously, air-fuel mixture amount minimizing in the crankcase when spray of falling also makes ventilation, aeration quantity deficiency when causing engine breathing influences the raising of engine power.

The utility model purpose is according to above-mentioned available engine deficiency in use, at engine intake a kind of special valve is set, when the piston stroking upward crankcase produces negative pressure, automatically inhale and open, make air inlet open, when descent of piston, crankcase produces pressure suction port is in time closed, fall spray to overcome gasoline, thereby both can reach program oil, and can improve engine efficiency.

It is by an one-way valve is installed at crankcase intake that the utility model is realized, this valve is by valve body, spool, spring, collar constitutes, the valve body profile is identical with common air inlet connections, but through hole wherein is the joint scalariform, spool is a round barrel shape, front end is round table-like, spool place in the through hole of valve body and with its Spielpassung, spring places the cylinder hole of spool, collar places the hole inner wall groove of valve body to block spring, under spring action, saves on the terraced line (or face) in terraced hole in the tightly sticking valve body of the tapered sidewalls of spool termination, porose on the sidewall of spool, prolonging with the corresponding section, hole on the spool sidewall vertically has groove.

Accompanying drawing 1 is the utility model master pseudosection;

Accompanying drawing 2 is the utility model plan view;

As accompanying

drawing

1,2 show, the utility model is by valve body (1), spool (2), spring (3), collar (4) constitutes, the profile of valve body (1) is identical with common air inlet connections, but through hole wherein (5) is the joint scalariform, spool (2) is a round barrel shape, front end (6) is round table-like, spool (2) place in the through hole (5) of valve body (1) and with its Spielpassung, spring (4) places the cylinder hole (9) of spool (2), collar (4) places the hole inner wall groove (1) of valve body, block spring (4), under the effect of spring (4), save on the terraced line (11) in terraced hole (5) in the tightly sticking valve body (1) of the tapered sidewalls (12) of spool (2) termination, certainly locate also can be processed into face at terraced line (11), porose on the sidewall of spool (7), hole must have 1 at least, under the strength condition that guarantees spool, the multiple-effect fruit can be good more more in the hole, present embodiment has adopted orthogonal four holes, and prolonging with the corresponding section, hole vertically has conduit (8), and conduit will make oil-feed more unobstructed.

Claims

1, a kind of two-stroke gasoline engine gasoline-saving device, it is characterized in that this device is made of valve body, spool, spring, collar, the valve body profile is identical with common air inlet connections, but through hole wherein is the joint scalariform, spool is a round barrel shape, front end is round table-like, spool place in the through hole of valve body and with its Spielpassung, spring places the cylinder hole of spool, collar places the hole inner wall groove of valve body to block spring, under spring action, save on the terraced line in terraced hole in the tightly sticking valve body of the tapered sidewalls of spool termination.

2, two-stroke gasoline engine gasoline-saving device according to claim 1 is characterized in that on the sidewall of spool porose.

3, according to right 1 or 2 described two-stroke gasoline engine gasoline-saving devices, it is characterized in that with the spool sidewall on the corresponding section, hole prolong groove vertically arranged.
