Abstract
The utility model is applied to various automobiles using carburettors. While the automobile travels without need of oil supply, the utility model mode can inhibit the oil supply, avoiding the unnecessary fuel consumption for the goal of fuel saving. Under the precondition of no change of any structure of the oil supply system, the utility model is arranged on the base hole of the main metering jet of the carburettor.
Description
This device is to be used for automobile to be in operation when not needing fuel feeding and to stop up the gasoline-saving device of metering-orifice automatically.Be applicable to the various types of automobiles of using Carburetor.
Automobile is in operation often to be had when not needing fuel feeding.Such as, when automobile runs at the mountain driving descending with in travelling that various situations need be slowed down or during Brake stop, just do not need to supply with oil plant to cylinder.But by traditional practice, under the above-mentioned situation that need not fuel feeding, the auto idle speed system fuel feeding that does as usual.In order to address this problem, all idle speed fuel saved device is studied both at home and abroad, and be applied on the automobile, reached certain oil-saving effect.But still there is complex structure in present idle speed fuel saved device, installs and uses inconvenience, Applicable scope is little, cost is than problems such as height.
Task of the present utility model is under the prerequisite that does not change the engine fuel system any structure, gasoline-saving device is installed on the main jet carrier hole of Carburetor, avoids the process and remould that carries out on Carburetor.
The structure of this fuel-economizing device is made up of main jet (1), metering-orifice (2), main jet body (3), pad (4), iron core (5), magnetic coil (6), needle-valve body return spring (7), needle-valve (8), pintle valve seat (9), body (10) as shown in the figure.Main jet (1), main jet body (3), needle-valve (8), body (10) are made with little materials of permeability such as copper, aluminium and aluminum alloys.Iron core (5), pintle valve seat (9) are made with big materials of permeability such as steel, iron and iron-nickel alloys.Needle-valve (8) is fitted on the pintle valve seat (9), forms needle-valve body (8,9).Leave 0.5 millimeter gap between needle-valve (8) and main jet body (3), the iron core, also leave 0.5 millimeter gap between pintle valve seat (9) and the body (10).So that needle-valve body (8,9) action.
Main jet (1) is to use the screw thread spinning on the main jet body, can change the standard main jet to the difference requirement of fuel delivery according to various types of vehicles, again according to automobile in the operating conditions of different regions requirement difference to fuel delivery, change the main jet (1) that is suitable for local operating conditions.Metering-orifice (2) is the passage of fuel feeding, when needle-valve moves, can constitute sealing with needle-valve (8), stops fuel feeding.Main jet body (3) is to use the screw thread spinning on body (10), it is the matrix that main jet (1) is installed, it is again the passage in main jet (1) fuel feeding source, while is as the guiding of needle-valve (8) action, when needle-valve (8) moves, needle-valve (8) is blocked the metering-orifice (2) of main jet body (3), and oil duct is closed, and stops fuel feeding.Pad (4) is contained between main jet body (3) and the body (10), can be as required by increasing or reduce the method for pad (4), adjust the stroke between needle-valve (8) and the metering-orifice (2), to obtain the fuel delivery of economical rationality, pad (4) can also be used to preventing leakage of oil simultaneously.Iron core (5) is fitted on the main jet body (3).Magnetic coil 6 is wrapped on the body (10).Needle-valve (8) is formed needle-valve body (8,9) with pintle valve seat (9), needle-valve body (8,9) return springs (7) are contained between iron core (5) and the pintle valve seat (9), return spring (7) is that main jet body at Carburetor uses (as the Dongfeng series automobile), the further like this using scope that enlarged during for horizontal configuration.Body (10) is as the matrix of main jet body (3) and magnetic coil (6) and hold needle-valve body (8,9) and iron core (5).
The using method of this fuel-economizing device is: this device is installed on the main jet body seat hole of Carburetor, magnetic coil (6) has two terminal wire, and one is connected on the battery feed of being controlled by ignition switch, and controls with a switch at operator cabin, when the needs idling, power supply is disconnected.Another root connects iron, promptly lead and switch is connected on certain position of the following of foot throttle pedal or fuel throttle pull bar, require when unclamping gas pedal, can connect bonding, and when stepping on the throttle pedal, can disconnecting circuit.Automobile is at descending or when running into situation etc. and need unclamp gas pedal, connect the iron wire bonding, magnetic coil (6) has electric current to pass through, iron core (5) and pintle valve seat (9) are magnetized and produce the moving needle-valve body (8,9) of magnetic force suction, make needle-valve body (8,9) action, needle-valve (8) is blocked the metering-orifice (2) of main jet body (3), stops fuel feeding, reaches the fuel-economizing purpose.When vehicle need continue operation when stepping on the throttle pedal, switch under the gas pedal disconnects under the effect of power, circuit is cut off, magnetic force disappears, needle-valve body (8,9) leaves the metering-orifice (2) of main jet body (3) under the effect of deadweight or spring force, make metering-orifice (2) unimpeded, continue fuel feeding, satisfy the needs that automobile continues operation.
Claims (3)
1, electromagnetic valve switch main jet gasoline-saving device is the main jet that utilizes electromagnetic valve switch Carburetor fuel feeding road.It is characterized in that solenoid valve by main jet (1), screw thread spinning on main jet body (3), pad (4), be contained between main jet (1) and the main jet body (3), iron core (5), magnetic coil (6), needle-valve body return spring (7), needle-valve (8), pintle valve seat (9), body (10) constitute.Main jet (1) is a scyewed joint with main jet body (3), and the main jet body also has scyewed joint with body (10) again.Body (10) outside is wound with magnetic coil (6), and the body inner core is equipped with iron core (5), return spring (7) and needle-valve body (8,9).
2, electromagnetic valve switch main jet gasoline-saving device according to claim 1 is characterized in that: main jet (1), main jet body (3), needle-valve (8), body (10), make with little materials of permeability such as copper, aluminium and aluminum alloys.Iron core (5), pintle valve seat (9) are made with big materials of permeability such as iron, steel, iron-nickel alloys.
