The engine energy-saving and purifying silencer device

The invention belongs to technical field of engines.

The patent No. is that 89216153.1 utility model patent has provided the patented technology that a kind of name is called " petrol engine energy-saving purifier ".This technology is under the carburetor throttle of motor mixer to be housed, and the air fuel ratio regulator is housed on the mixer; The gas blowby conduit is arranged, and an end is connected with crankcase, and the other end is connected with mixer, or is communicated with mixer by the air fuel ratio regulator; Also be provided with the gas blowby arm on the gas blowby conduit, the gas blowby arm inserts the suitable for reading of Carburetor; Heater (annular cavate heater) is housed on outlet pipe, thermal baffle both sides in the heater is equipped with air conduit and hot gas conduit respectively, air conduit is connected with the air-strainer of motor, and hot gas conduit inserts on the air fuel ratio regulator, is communicated with mixer by the air fuel ratio regulator; On outlet pipe, also be equipped with taperedly, and have the suction tude of one-way valve and adjusting screw, as the tail gas after burner by suction port.The energy-saving and purifying principle of above-mentioned patented technology is that to-and-fro motion suction by cylinder is with in the clean air suction heater in the air-strainer, after the heating of outlet pipe tube wall high temperature, enter in the mixer by the air fuel ratio regulator, the low-temperature mixed gas that comes with Carburetor mixes, thereby improved the temperature of mixed gas, improved the atomizing effect of fuel oil, the effect of oil inflame is improved, with this, reach purpose energy-conservation, the noxious gas emission minimizing; To entering the fuel oil gas blowby in the crankcase in the cylinder operation, import in the mixer by gas blowby conduit and gas blowby arm, after in mixer, mixing, enter cylinder and rekindle, like this, both saved the energy, reduce gas blowby again and directly discharged the pollution that causes; Enter hydrocarbon and carbon monoxide in the outlet pipe for not being fully burned, then burn, to reduce discharge of harmful gases by the after burner that is installed on the outlet pipe.The shortcoming of said apparatus is atomizing effect and the air fuel ratio that is confined to improve mixed gas, oxygen to the decision fuel combustion efficiency fires than can't further improving, because oxygen content is certain (being about 21%) in the air, so air fuel ratio is right in becoming fixed proportion with oxygen.Another shortcoming of said apparatus is the engine cold-start difficulty.Because during engine cold starting, its outlet pipe also is not heated, the gas that enters from heater in the mixer is cool air, not only can not improve the temperature of mixed gas, improves fuel atomization effect, make the fuel oil density unevenness in the mixed gas even on the contrary, cause the engine ignition difficulty thus.

The objective of the invention is to propose a kind of oxygen combustion ratio that can improve engine combustion efficiency, and the burning factor such as degree of mixing, temperature, humidity, intake and exhaust relaxation process that obtains mixed gas when making engine operation is distributed rationally, make full combustion of fuel, reduce environmental pollution, and the technological scheme that does not influence engine cold starting.

For achieving the above object, the present invention is making following improvement on the basis of 89216153.1 patents: its technological scheme is an exchanger 7 (seeing Fig. 1,5) exchanger 7 to be set be made up of vent 19, the air intake filter 33 that is provided with on housing and the aqueous vapor hole 40 of the air collecting chamber in housing 29, the housing 37, air collecting chamber upper end between heater and radiator; Aqueous vapor hole 40 is inserted on the return pipe 9 of radiator 10 by conduit 8; Vent 19 is connected with heater 15 by supply conduit (original name air conduit) 18.The working principle of present technique is: when engine operation, suction by cylinder, in air collecting chamber, form negative pressure, make air enter air collecting chamber after 37 interior mixing by aqueous vapor hole 40, enter in the heater 15 by vent 19 and supply conduit 18 again by the aqueous vapor in filter cleaner 33 and the radiator.

For regulating the aqueous vapor flow, on conduit 8, can install a cock of water drain 8 '.

For the gas flow that enters in the mixer 3 can be regulated, the present invention's exchanger is provided with the gas flow adjuster (see figure 2).Gas flow adjuster is by the top that is arranged on housing 29, and left end is the regulation and control chamber 25 that vent 19, right-hand member are communicated with air collecting chamber, and the hollow valve body 21 in the regulation and control chamber, is sleeved on retaining spring 31 compositions on the valve body 21; One end of valve body 21 is taper, is provided with little vent 30 in the tapered end, and there is big vent 32 at the middle part, and the other end has spring seat 22, and the awl end of valve body 21 does not contact with vent 19.Like this, when engine idle usefulness gas after a little while, closure is bordering on closure, negative pressure in the mixer 3 increases, and valve body 21 is inhaled the elastic force that overcomes retaining spring 31 and is moved to the left, and its awl end blocks vent 19, gas in the air collecting chamber 37 can only pass through from little vent 30, and air feed is reduced.When the non-idling of motor, engine speed improves gradually, negative pressure in the mixer 3 reduces, retaining spring 31 also restores to the original state thereupon gradually, the awl end and the vent 19 of valve body 21 are broken away from, a large amount of gases enter in the regulation and control chamber 25 from the big vent 32 of valve body 21, and air feed is increased, to satisfy the needs that engine operation increases gas consumption.

Be the pressure of stabilizing gas, improve quality of filling gas, between air collecting chamber and regulation and control chamber, be provided with the air feed chamber 27 that interconnects, switching network 39 and high magnet 28 are housed between air collecting chamber and air feed chamber.Switching network 39 preferably use to unburned hydrocarbon in the gas and hot air have absorption, the material that desorbs effect makes, as active carbon etc.

The rectangular pyramid shape face of projection is preferably adopted in air collecting chamber of the present invention bottom surface 38.

Because of the idling gas consumption difference of various motors, the situation of air feed deficiency only can take place in the motor that has with little vent 30 air feed in the valve body under idling mode.For addressing this problem, its technological scheme is that an adjusting screw 24 that has the angle of inclination is set on housing 29, has a U-loop groove on spring seat 22, and the bottom of adjusting screw 24 can be stretched in the U-loop groove.Like this, adjusting screw 24 upper and lower moving just can limit the distance that valve body 21 is moved to the left, and to adjust the closed degree of valve body 21 awl ends and vent 19, reach the purpose of the Throughput of further control vent 19.

The technological scheme that solves engine cold-start is that (or outside) is equipped with electric heating element 48 (see figure 6)s in hot gas conduit 17, the lead of electric heating element 48 is connected respectively with the both positive and negative polarity of motor power supply 51, and its control circuit is made up of the engine ignition switch 13 and the temperature control element 50 of device in hot gas conduit 17 that are connected in the heater circuit.Like this, when engine start, the gas by in the electric heating element heat hot airway makes motor be easy to retrofire.When the temperature in the hot gas conduit reached setting value, temperature control element disconnected circuit automatically.Also available delay switch 14 (see figure 7)s of temperature control element 50 in the above-mentioned control circuit replace, and when electric heating element work during to time of setting, delay switch 14 cuts off the power supply heater circuit.
