Description

Automatic fuel level adjusting economizer for carburetter of gasoline engine

The utility model relates to a kind of, according to the gasoline-saving device of the corresponding adjusting Carburetor of petrol engine load condition pasta.

The gasoline engine carburetor of automobile coupling all is provided with the adjusting screw that is used to regulate monkshood chamber pasta, and the pasta adjusting screw acts directly on the monkshood frame, and the twisting adjusting screw moves down the monkshood frame, and pasta raises; Upwards moving it then, pasta reduces.Pasta is low excessively, and petrol engine power descends, and is short of power, and is difficult for starting.Pasta is too high, and oil consumption is many.So the general pasta of adjusting all is to take into account pasta, what is called is taken into account pasta, guarantees the minimum pasta of the certain power of petrol engine exactly.That is to say when load is big it is the pasta that relatively is fit to, hour has been exactly high pasta at load so.Pasta is after adjusting, and general being difficult for changes; Change if desired, the essential twisting adjusting screw of stopping.Under the certain situation of pasta, when petrol engine load hour, the relative mistake of petrol engine power won, and should turn down pasta, but not transfer in travelling.When petrol engine load is bigger, when petrol engine occurring and being short of power, (Carburetor generally all is provided with and wind) general adopts to draw with wind its oil-feed is increased, and improves mixture strength and remedies and be short of power.

Draw with wind be by with wind backguy gas-entered passageway is closed a part, the jet negative pressure is increased, oil spout speeds up, thereby the gasoline that enters cylinder is increased.But, owing to close a part of gas-entered passageway, the oxygen that enters cylinder is reduced, the gasoline that enters in the cylinder can not fully burn, and draws and wind outlet pipe over-emitting black exhaust waste gasoline, contaminated air.Drivers all know turn down pasta can fuel-economizing, still, it is to be difficult for starting that pasta crosses low one, the 2nd, load is short of power when big.Show on the automobile to be exactly to go up a slope weakly, acceleration performance reduces.

The purpose of this utility model be to provide a kind of according to the petrol engine load condition at any time can corresponding adjusting pasta between advancing device.Pasta and petrol engine are loaded organic the cooperation, thereby realize and the corresponding adjusting mixture strength of load, save oil consumption.

The purpose of this utility model is achieved in that original adjusting screw is changed into plunger, can be in axial sliding, add a fixed plate at the Carburetor edge, fixed plate is provided with connecting rod and rocking arm, and guides in the operator cabin by backguy, be provided with Joystick in the operator cabin, pull handle under steam, by continuous action device, the monkshood frame can move up and down under plunger and the spring action of monkshood frame, with former adjusting screw in like manner, thereby can obtain desirable pasta.One kilogram of gasoline perfect combustion needs 15 kg of air per kg of water evaporated, and said exactly air fuel ratio is 15:1.If the actual air fuel ratio that enters cylinder is a with the ratio of standard air fuel ratio.Petrol engine in actual motion, when a=0,8 left and right sides, its output power maximum; But because air inflow is inadequate, gasoline can not perfect combustion, so oil consumption rate is higher.When a=1,2 left and right sides, its output power is less, do not reach maximum rated power, but its oil consumption rate is minimum.The petrol engine of automobile coupling, 3/4 of its rated power is stand-by power; Only use its power of 1/4 during cruising; Its stand-by power is to use during fully with situations such as acceleration, upward slopes.This " gasoline engine carburetor is regulated the pasta gasoline-saving device automatically " can adjust monkshood chamber pasta at any time between advancing, flow resistance when utilizing the height difference of pasta and jet to adjust gasoline to be inhaled, no matter rotating speed is much under the less situation of load to make petrol engine, make about its a=1.2, gasoline has had sufficient air to react with it, sufficient combustion has satisfied the low power requirement of high rotating speed of automobile, thereby saves gasoline.When petrol engine needs big the load, can heighten pasta at any time, mixed gas is thickened, satisfy high-power needs.

The utility model is simple in structure, with draw with wind facies than not increasing operation easier.This installs alternative manual accelerator control and wind two covering devices.Original adjusting screw is once adjusting pasta, and on a level, just the height difference of pasta and jet is certain all the time for pasta, hour should not hang down at load, should not get on by the height height than greatly the time at load, can not walk stretch parking accent once.So have to adjust with drawing with wind, preamble said that what many air that gasoline advances in the cylinder when drawing with wind advanced lacked, and it is bad to burn, waste gasoline, contaminated air.The utility model according to circumstances can be adjusted pasta at any time between advancing.Load adopts high pasta when big owing to do not close gas-entered passageway, oxygen abundance in the cylinder, the steam oil ratio (SOR) that enters cylinder draw with the wind burning thoroughly.Load hour reduces pasta, and the gasoline that enters cylinder is reduced, and mixture strength is thinning.Thereby saving gasoline reduces and pollutes.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
