Abstract

The utility model discloses an apparatus for adding water to combustion of an engine. The utility model comprises an air cleaner 9, control valves 11, 12, a control valve switch 10, a water atomizing system 13 and an improved idling regulating screw 2, wherein, the water atomizing system comprises a water tank 14, a water outlet nozzle 15 and a pipe with a thin waist 16, and the improved idling regulating screw 2 is provided with a through hole 3. A discharge outlet 4 is just opposite to the position of a passage 6.

Description

A kind of engine water-injection combustion device

The utility model relates to a kind of engine water-injection energy saving device.

The main mode of available engine control oil consumption and discharging is to adopt the method for lean combustion, that is to say by injecting excessive air and improve air fuel ratio, promote the abundant burning of fuel, thereby reach energy-conservation and reduce the requirement of discharging, this method relates to the transformation to engine structure, improved the cost of motor, also only be used at present in some comparatively high-grade automobiles.

The purpose of this utility model is to provide a kind of simple and easy to do engine energy-saving and environmental protection new equipment, and it is to realize and inject the same or better effect of excess air by inject proper amount of water in motor.This device is suitable for adopting the motor and the fuel-injected motor of carburetor structure,

This device is made up of air-strainer, control valve, control valve switch, water atomization system and improved idle adjusting screw (this screw is used for carburetor circuit), when motor is started working and reach certain racing speed, the control valve switch is opened control valve, utilize in-engine vacuum that air is sucked from filter cleaner, make current quicken and be separated into the vaporific small globule at thin waist tube by the water atomization system.Quicken at motor, normally why not speed or between deceleration period atomized water sucked in the motor in right amount and mixed with inflammable mixture, because the proportion of water is greater than oil, fogging oil in the inflammable mixture will inevitably be adsorbed in the surface of each atomizing droplet, and enter the water particulate of firing chamber, under the process high-temperature high-voltage reaction, make oil more wide with the burning surface of contact of oxygen, because contained oxygen also has combustion-supporting effect in the water, fuel finally more can obtain fast burning fully, thereby reaches the effect of energy saving and reduction discharging.

Below in conjunction with figure and embodiment the utility model is further described:

Fig. 1 uses schematic representation for the idle adjusting screw sectional drawing after improving and with whole water-injection combustion device binding; Comprise main chamber 1, improved idle adjusting screw 2, the path 6 between idling transitional pore and idle jet, and idle jet chamber 7;

Fig. 2 is the water atomization system schematic in the water-injection combustion device described in the utility model, comprises water tank 14, water outlet nozzle 15 and thin waist tube 16;

Fig. 3 is the control valve structural representation in the water-injection combustion device described in the utility model;

Fig. 4 is the use schematic representation of the utility model in fuel injected engine.

Embodiment 1:(is referring to Fig. 1)

For realizing the utility model design one through hole 3 in the middle of idle adjusting screw 2, when this improvement idle adjusting screw 2 is packed Carburetor into, the exhaust outlet 4 of the through hole 3 in the middle of the improved idle adjusting screw 2 is located in the idling jet chamber 7 over against path 6 places, and through hole hold 8 to be linked in control valve 12 in addition, by air-strainer 9, the atomized water that control valve 11 and water atomization plant 13 form enters main chamber 1 through through hole 3 from exhaust outlet 4 again by control valve 12, with have an effect after inflammable mixture mixes, this device moves greater than idle speed of engine 50～100r.p.m the time, will reach optimum efficiency.When implementing, control valve switch 10 is bound up on

control valve

11,12 with the Motor Vehicle tachometer on, when idle speed of engine reaches certain value, control valve switch 10 is opened

control valve

11 and 12, because the vacuum of Carburetor inside sucks air from air-strainer 9, make water fogging by water atomization system 13, atomized water forms an aqueous vapor curtain through through hole 3 backs at 7 places, idle jet chamber, the oil circuit in idle jet chamber 7 is blocked, this moment, the ratio of inflammable mixture was to determine by the air stream that enters main chamber 1 through main jet with by the air that idle adjusting screw 2 enters, that is to say, in acceleration or moderating process, because the variation of choke tube barrel stage internal air pressure,, can not cause water by excessive suction with making that the inflammable mixture that enters from aditus laryngis is proportional all the time with the atomized water that enters from idle adjusting screw 2.

Embodiment 2:(is referring to Fig. 4)

This figure is depicted as the embodiment of water-injection combustion device in fuel injected engine, it comprises air-strainer 9, water atomization plant 13 and control valve 12, this device are arranged between air throttle 17 and the cold starting sparger 18, and atomized water is brought cylinder into by air and mixed with the oil of sparger 19 ejections in cylinder, under High Temperature High Pressure, have an effect, the oil that is adsorbed on the surface is popped, make oil firing complete, reach fuel saving, reduce the purpose of discharging.
