Abstract

The utility model discloses an impeller type atomizing oil-economizer, which is mainly characterized in that the inner wall of a throat 4 is provided with a supporting rod 2 which is vertical to an impeller shaft 1; the impeller shaft 1 is provided with more than two vanes 3 with tapered tops; the lead angle of the vane 3 can be in the range between 30 to 45 DEG. The intake resistance of the device is little, and consequently, each cylinder is distributed more uniformly. The oil film of an intake duct is reduced, so thatthe combustion performance of each cylinder is more consistent and each cylinder combusts more in time. The utility model has the advantages of high oil gas atomizing degree, complete combustion, less pollution, simple structure, convenient installation and low cost.

Description

Impeller type atomizing oil-economizer

The utility model relates to carburetors for internal combustion engines, relates in particular to a kind of impeller type atomization fuel-saving device.

In the prior art, the improved gasoline-saving device of Carburetor is a lot, and atomization oil-saving device has nine orifice plates, spiral trunnion, spiral chute pattern, and these fuel economizers are generally all simple in structure, easily manufactured, can strengthen gasoline and further atomize, and has certain oil-saving effect.Open " a kind of gasoline atomizing gasoline-saving device " patent No. 87209024 of Chinese patent, its major technique is characterised in that and is provided with two guide rings that have some spiral stream guidance blades respectively, and the Hand of spiral face of the guide vane of two guide rings is opposite, this device is easy for installation, the oil gas fogging degree is good, has oil-saving effect, but this gasoline-saving device causes intake resistance excessive, the guide ring that mainly is the spiral stream guidance blade is fixed, influences engine output.

The purpose of this utility model provides a kind of engine output that neither influences, and oil gas is further atomized, and with the realization oil-saving effect, and increases engine horsepower.

The purpose of this utility model is to realize like this, a kind of impeller type atomization fuel-saving device, it is characterized in that: the trunnion inwall is provided with a supporting rod perpendicular to impeller shaft, 2 blades that have tapering with upper top are arranged on the impeller shaft, the lead angle of blade can be between 30 °-45 ° in the scope, being installed in the trunnion internal supporting rod can adopt on inwall boring that supporting rod is put into the back welding, also can adopt directly is welded on the inwall, this device both can be installed on the closure of Carburetor, be in the big trunnion, also can be installed under the carburetor throttle, promptly connect in the bearing.

The utility model compared with prior art has following effect:

1, simple in structure, easy for installation, with low cost.

2, oil gas fogging degree height, burning reduce atmospheric pollution fully.

3, intake resistance is little, and it is more even that each cylinder is distributed, and reduces the intake duct oil film, makes each cylinder combustion performance more in time consistent.

4, improve trunnion and intake duct oil gas flow velocity, thereby increase engine horsepower, acceleration performance is good.

Fig. 1 is the utility model trunnion A-A master sectional views;

Fig. 2 is the utility model trunnion plan view;

Fig. 3 is that the utility model connects bearing A-A master sectional views;

Fig. 4 is that the utility model connects the bearing plan view.

Drawing is explained: impeller shaft 1, and supporting rod 2, blade 3, trunnion 4 connects bearing 5.

Below in conjunction with accompanying drawing the utility model is further described:

The utility model mainly is at domestic Carburetor some operating mode on motor, there is design under the relatively poor situation of oil gas atomization as little operating mode, acceleration, the big closure slow-speed of revolution, this fuel economizer adopts the Samsung impeller, utilize mixed air vessel's high velocity air, make blade 3 produce high speed rotating, reach short stream effect, further improve trunnion oil gas flow velocity, reach the further burning of gasification oil, thereby increase engine output, improve pick-up of engine greatly.

Fig. 1 is the gasoline-saving device that impeller is set at the inwall of trunnion 4, from figure as can be known, is provided with supporting rod 2 in the inwall 4, is provided with an impeller shaft 1, blade 3 is housed on axle perpendicular to supporting rod 2 centers, and blade 3 tops are provided with conehead, to reduce the resistance in the trunnion 4.This device proves that by long-term road test result the lead angle design of blade 3 is at 45 degree, and the oil gas fogging degree is best, reaches oil-saving effect the best, but general fuel-economizing is more than 10%.

Fig. 2 is arranged on the schematic representation that connects in the bearing 5 with this device, and the impeller that this connection bearing 5 is provided with is identical with the impeller Connecting format that is arranged on trunnion 4.Mainly be the difference of installation position, this connection bearing 5 can be arranged on the closure or under.

The utility model can be according to the different structure of various Carburetors, the size and location of mixed air vessel's diameter.Can design different trunnion 4 and be connected bearing 5 and be connected with Carburetor.

Claims

1, a kind of impeller type atomization fuel-saving device, this device mainly is technical improvement the at the big trunnion of existing petrol engine carburetor, it is characterized in that: trunnion 4 inwalls are provided with a supporting rod 2 perpendicular to 1 in impeller, and 2 blades 3 that have tapering with upper top are arranged on the impeller shaft 1.

2, impeller type atomization fuel-saving device according to claim 1 is characterized in that: the lead angle of blade 3 can be between 30-45 ° in the scope.
