CN2157313Y - Revampment of fuel supply system for mixed fuel type motorcycle - Google Patents

Abstract

The utility model belongs to the refitment of an oil supplying system for the existing mixed oiling type motorcycle. The utility model is characterized in that a single-float hand pump type carburetor of the mixed oiling type motorcycle is taken away, and a double-flange connecting tube is used for installing a double-float automatic pump type carburetor of the motorcycle on an engine of the mixed oiling type motorcycle; an automatic oil supplying pipe which is inserted into the connecting tube is connected with a sump through an oil delivery pipe, engine oil is individually and automatically supplied, and the purpose of separately supplying the engine oil and gasoline is realized. The motorcycle after refitting is convenient for oiling, the engine oil and the gasoline are uniformly mixed, and the gasoline can be saved by 35%; pump oil is not used when the motorcycle is started, which is convenient and clean; a gasoline throttle is flexible, and travel is small; the carburetor is firmly connected, and is not easy to loosen; sealing performance is good, oil is not leaked, machine performance is enhanced, and machine life is extended.

Description

Revampment of fuel supply system for mixed fuel type motorcycle

The utility model belongs to the automotive engineering field.

At aspects such as structure, appearances significant improvement has been arranged though mix oiling formula motorcycle, its single floating hand pump formula Carburetor is kept intact always, and to the atomization badness of its existence, oil consumption is big; The starting of pump oil, the gasoline waste is bigger; The telescopic connection time has been grown loosening easily; Bad sealing, leakage of oil causes vehicle body to pollute easily; And throttle line never obtains correcting and improving with defectives such as Carburetor piston disconnections sometimes.Machine oil and gasoline mix inhomogeneous, and the performance and the life-span of machine are adversely affected.

The purpose of this utility model provides a kind ofly mixes to mixing the conversion apparatus of oiling formula motorcycle oil supply system, making that oiling formula motorcycle becomes gasoline and machine oil separately adds, and further improves machine performance and life-span.

The repacking of the oil supply system of this mixing oiling formula motorcycle is by having invented a coupling tunnel and having realized for the assembling device of pipe automatically.The structure of coupling tunnel 1 is the cylinder of a flanged dish in two ends, and two flange plate are all porose, open a hole on the barrel, and this hole is used for inserting auto-supply pipe 2.The body of auto-supply pipe is a bend pipe 3, and a crooked end is threaded with a tubular nut head 4 and matches, and spring 5 and ball 6 are housed in the nut head, and the other end of nut head is by the transport pipe fuel tank of meeting sb. at the airport.Concrete repacking measure is that the original floating hand pump formula Carburetor of a list that mixes oiling formula motorcycle is dismantled, and with the flange plate at coupling tunnel two ends the two floating self-pump type's Carburetors of motorcycle is installed on the mixing oiling formula motorcycle engine.Working procedure is when motorcycle starting back because suction, and ball 6 is inhaled removes the aperture, and the machine oil input enters coupling tunnel by the auto-supply pipe, and gasoline also pumps into coupling tunnel by two floating self-pump type's Carburetors and machine oil evenly enters motor after the mixing simultaneously.Realized that machine gasoline branch adds.When motorcycle was put out a fire, suction disappeared, and ball 6 sets back under the promotion of spring 5, blocks the aperture, fuel cut-off.(seeing accompanying drawing 1)

In addition air-strainer is reequiped, change former iron shell into small-sized hard plastic shell, refill changes the sponge core into and the repacking of above oil supply system matches.

Motorcycle after the repacking has realized that machine oil and gasoline branch add, and becomes original telescopic connection, for screw connects.Its superiority is: machine gasoline mixes, and is easy to lubricate, under the situation that keeps former power, can save gasoline 35%; Starting is saved trouble without pump oil, and is clean; Throttle is flexible, and stroke is little; Carburetor connects firmly, is difficult for loosening; Good seal performance, oil-proof, can prolong machine working life.Parts are easy to manufacture, reequip easy.

Description of drawings: Fig. 1, coupling tunnel and auto-supply pipe assembling device plan view.Among the figure: 1, coupling tunnel, 2, the auto-supply pipe, 3, bend pipe, 4, the tubular nut head, 5, spring, 6, ball.

Fig. 2: coupling tunnel flange plate A is to view.

Claims (2)

1, mixes the repacking of oiling formula motorcycle oil supply system, it is characterized in that having the double flange coupling tunnel in a hole, the two floating self-pump type's Carburetors of motorcycle are installed in mix on the oiling formula motorcycle engine with barrel; The coupling tunnel cinclides inserts the auto-supply pipe, and it connects by transport pipe and sump; Air cleaner casing is the small plastic duricrust, and interior is the sponge core.

2, the repacking of mixing oiling formula motorcycle oil supply system as claimed in claim 1, the body that it is characterized in that the auto-supply pipe is a bend pipe, a crooked end inserts coupling tunnel, the other end has screw thread, match with a tubular nut head, spring and ball are housed, the other end dress transport pipe of nut head in the nut head.
