Description

The ignition internal combustion engine vaporizer

Technical field

The present invention relates to the vaporizer in the fuel supply system, be specifically related to the ignition internal combustion engine vaporizer.

Background technique

The vaporizer of existing spark-ignition engine has two kinds of carburetor type and EFI device formulas: 1, carburetor type, Carburetor is by the float chamber of band float mechanism (float needle valve) and metering-orifice, jet pipe, the air duct that has trunnion, closure and startup belt speed, main fuel feeding enrichment-system is formed, its function is when air flows into carburetor throat, because trunnion is thinner, flow velocity speeds, thereby the trunnion place produces low pressure forces fuel from each nozzle hole ejection, the fuel of ejection is dispelled by the high velocity air of cylinder, enter combusted cylinder after forming superfine mist of oil and air mixing, also have starting, idling, acceleration enrichment device is to adapt to the needs of Under Different Work Condition of Engine; 2, EFI device formula, sparger is made up of nozzle needle, battery coil plunger, electromagnetic wire, filter cleaner, fuel supply line etc., when power connection, its pulling plunger and needle-valve makes it to leave spout, because electricity is when connecting, electromagnetic coil produces magnetic field, plunger is moved to the electromagnetic coil direction, needle-valve lifts, and is separated from nozzle, and fuel is sprayed in the suction tude by nozzle then; Their common shortcomings that exists: 1, Pen Chu liquid fuel is vaporized while mixing with air, promptly mix---vaporization, because the air temperature that runs into is low, it is short to enter the time of gasifying before the cylinder, especially not evaporable composition in the fuel, thereby the degree of vaporization is low, it is insufficient to burn, and waste of fuel is big, and harmful matter is many in the waste gas, influence power character, the Economy of motor, and carbon deposit is many; 2, the transitionality between each operating mode of Carburetor is poor, the ejecting system complicated layout of sparger, and cost is higher.

Summary of the invention

The purpose of this utility model is: a kind of ignition internal combustion engine vaporizer is provided, and fuel is earlier through vaporizing chamber vaporization, the complete vaporized fuel and the air mixing of ejection, promptly vaporize earlier and afterwards mixes, enter the abundant fuel of energy behind the cylinder, the reduction oil consumption, reduce waste gas, improve and start motor-driven effect.

Technical solution of the present utility model is: this vaporizer mainly is made up of float chamber, ascending pipe, ascending pipe control valve, vaporizing chamber, connecting tube, main jet pipe, outlet pipe, suction tude, outer wall at outlet pipe is established vaporizing chamber, vaporizing chamber is communicated with suction tude by the main jet pipe, float chamber connects vaporizing chamber by ascending pipe through the ascending pipe control valve, and the two ends of connecting tube connect float chamber and vaporizing chamber respectively.

In the ignition internal combustion engine vaporizer of the present utility model, establish mixing chamber on suction tude, the main jet pipe that is communicated with vaporizing chamber is communicated with suction tude through mixing chamber.

In the ignition internal combustion engine vaporizer of the present utility model, electrical heating elements is installed in the vaporizing chamber.

In the ignition internal combustion engine vaporizer of the present utility model, an end of air breathing pipe is communicated with vaporizing chamber.

In the ignition internal combustion engine vaporizer of the present utility model, the closure of mounting strap speed governing backguy on suction tude.

In the ignition internal combustion engine vaporizer of the present utility model, petrolift is installed on the ascending pipe.

The utility model fuel flows out through float chamber, ascending pipe from fuel tank and flows into vaporizing chamber, is sprayed into suction tude and air mixing from the combustion gas main jet mouth of pipe after the vaporization fully, enters cylinder then.

The utility model prestart is opened Oil Switch, and fuel enters vaporizing chamber, when level of fuel rises to certain altitude, ascending pipe and connecting tube equal immersed in liquid level, float chamber does not have air to enter, fuel can stop to inject automatically.

The utility model air enters in the vaporizing chamber through breathing pipe, when flowing out vaporizing chamber (be similar to the foam gasoline in the Carburetor, but this being than its better effects if), more helps the vaporized fuel and the air mixing that spray.

The air pressure of float chamber liquid level is equated all the time with the air pressure of ascending pipe, and the fuel that ascending pipe flows out is that not to be subjected to the aperture of closure be the influence of degree of vacuum to the pressure by pressure of self or petrolift.

The utlity model has following advantage: 1, fuel is vaporized through vaporizing chamber earlier, this not evaporable composition also is forced to vaporization in the fuel, the complete vaporized fuel of ejection is that combustion gas mixes easily with air, i.e. vaporization---mix, can fully burn after entering cylinder, improved the power character of motor greatly, Economy, and also carbon deposit is few;

2, because fuel combustion is abundant, thereby harmful components such as CO, HC significantly reduce in the waste gas of discharging;

3, because fuel vaporize earlier afterwards mixes, the moisture in the fuel also the while vaporized fully, enter to play behind the cylinder and subtract quick-fried effect, turn bane into boon;

4, supply with the fuel of vaporizer, be not subjected to closure variation influence and increase and decrease synchronously with closure, the increment of fuel and air all is designed to straight line type, but their increase and decrease amplitude slope difference, thereby can adapt to the needs of each operating mode, transition gets very steady mutually simultaneously.

5, reduced requirement to fuel.

Be fuel-bound vaporizer sectional drawing with the ethanol petrol with regard to single-cylinder engine below, the utility model is described in further detail.
