Abstract

A balancing method for a four-cylinder carburetor includes: dismounting the carburetor, using a second cylinder carburetor as standard to adjust an idling adjusting screw so as to allow a throttle of the second cylinder carburetor to cover four fifths of an fuel hole of an idling fuel spray nozzle, observing area between a throttle of a third cylinder carburetor and the fuel hole of the idling fuel spray nozzle, screwing a throttle adjusting screw of the third cylinder inwardly when the area is smaller than four fifths and retreating the throttle adjusting screw of the third cylinder outwardly when the area is larger than four fifths so as to allow openness of the throttles of the second cylinder carburetor and the third cylinder carburetor to be identical, continuing to adjust the first cylinder carburetor and the fourth cylinder carburetor accordingly to allow the areas between throttles of the first, third and fourth cylinder carburetor and the fuel hole of the idling fuel spray nozzle to be synchronous with that of the second cylinder carburetor, screwing the gas mixture fine adjusting screws of the four cylinder carburetor to the end, and retreating by two circles.

Description

The balance method of four cylinder Carburetors

Technical field

The present invention relates to petrolic fuel atomization device, is a kind of balance method of four cylinder Carburetors concretely.

Background technique

The Carburetor that four cylinder engine mates is, four Carburetor synchronously uses in parallel, because of closure wearing and tearing and motor four cylinders wear and tear inconsistent, cause cylinder pressure and the Carburetor disequilibrium of every cylinder, and four general cylinder Carburetor balances, must come valve block and mixed gas are adjusted by four cylinder equilibristats, the oil consumption that causes with the fuel feeding differentiation of avoiding four cylinder Carburetors be large, seriously polluted.

Summary of the invention

The object of the present invention is to provide a kind of balance method of four cylinder Carburetors, have the reduction oil consumption, increasing service life of engine reduces exhaust emissions.

The present invention realizes with following technological scheme: the balance method of these four cylinder Carburetors, operating procedure is as follows: pull down Carburetor, take the second cylinder Carburetor as benchmark, regulate idle adjusting screw, make the closure of two cylinder Carburetor just cover 4/5ths to the oilhole of slow-running jet, at this moment, observe the closure of the 3rd cylinder Carburetor and the area of orifice of slow-running jet, less than 4/5ths, the throttle adjust screw of three cylinders is rotated inward, greater than 4/5ths, the throttle adjust screw of three cylinders is moved back outward, make two, the closure of three cylinders is in same aperture, according to the method for adjusting three cylinder closures, continue a cylinder and four cylinders are adjusted, make a cylinder, three cylinders, the throttle opening of four cylinders and the area of orifice of idling jet are synchronized with two cylinder, then the mixed gas micrometer adjusting screw of the Carburetor of four cylinders all is screwed to the end, withdraws from 2 circles and get final product.

The invention has the beneficial effects as follows, directly by naked eyes the closure of four cylinder Carburetors is carried out fast and efficiently balance, to realize the fuel feeding conformity of four cylinder Carburetors.

Embodiment

A kind of balance method of four cylinder Carburetors, operating procedure is as follows: pull down Carburetor, take the second cylinder Carburetor as benchmark, regulate idle adjusting screw, make the closure of two cylinder Carburetor just cover 4/5ths to the oilhole of slow-running jet, at this moment, observe the closure of the 3rd cylinder Carburetor and the area of orifice of slow-running jet, less than 4/5ths, the throttle adjust screw of three cylinders is rotated inward, greater than 4/5ths, the throttle adjust screw of three cylinders is moved back outward, make two, the closure of three cylinders is in same aperture, according to the method for adjusting three cylinder closures, continue a cylinder and four cylinders are adjusted, make a cylinder, three cylinders, the throttle opening of four cylinders and the area of orifice of idling jet are synchronized with two cylinder, then the mixed gas micrometer adjusting screw of the Carburetor of four cylinders all is screwed to the end, withdraws from 2 circles and get final product.

Claims

1. the balance method of a cylinder Carburetor, operating procedure is as follows: pull down Carburetor, take the second cylinder Carburetor as benchmark, regulate idle adjusting screw, make the closure of two cylinder Carburetor just cover 4/5ths to the oilhole of slow-running jet, at this moment, observe the closure of the 3rd cylinder Carburetor and the area of orifice of slow-running jet, less than 4/5ths, the throttle adjust screw of three cylinders is rotated inward, greater than 4/5ths, the throttle adjust screw of three cylinders is moved back outward, make two, the closure of three cylinders is in same aperture, according to the method for adjusting three cylinder closures, continue a cylinder and four cylinders are adjusted, make a cylinder, three cylinders, the throttle opening of four cylinders and the area of orifice of idling jet are synchronized with two cylinder, then the mixed gas micrometer adjusting screw of the Carburetor of four cylinders all is screwed to the end, withdraws from 2 circles and get final product.
