Description
The automobile fuel saving exhaust purifier belongs to the petrol engine technical field.
The utility model is primarily aimed at shortcoming that my CN90222757.2 utility model patent exists and improved.There is following shortcoming and defect in the CN90222757.2 utility model patent:
1, its adjustable flow filter cleaner can only be debugged once when mounted, can not change with the working conditions change of car thereafter, causes the exhausted air quantity of giving when idling operation bigger, and the exhausted air quantity deficiency of when height, middling speed, giving on the contrary, the slyness during influence gearshift transition.
2, some banger there is oil-saving effect preferably, but new car is not had oil-saving effect.
3, do not have corresponding expansion air jet after dwindling the fuel oil main jet, both destroyed the original operating conditions of Carburetor after, do not set up new, rational operating conditions; Or say waste gas can only heat supply can not oxygenating, so after dwindling the fuel oil main jet, easily produce not foot phenomenon of fuel feeding.The driver is forced to open the throttle wide, thinks fuel-efficient the possibility of result waste oil on the contrary.
4, waste gas is led return tray and must hole just feasible in place time-consuming, the effort of leading return tray when mounted on exhaust wall.
5, dwindle the constrictor of fuel oil main jet, very responsive to the temperature variation of fluid, so its flow change with the variation of ambient temperature, extremely difficult stable.
The purpose of this utility model is a kind of oil-saving clarifier that is fit to all kinds of new used cars, each season, each journey operating conditions, is convenient to install of design.Its way is to utilize the kinetic energy and the heat of an amount of waste gas, after the fresh air that covers mixes, forms the stereo rotating eddy current.Promote combustible gas stream fuel oil is fully gasified, adjustable flow filter cleaner and closure open-shut linkage, stepless modulation is to reach lean-burn, fuel-economizing, minimizing blowdown but also do not reduce the purpose of former design motivation performance.
The utility model is by dwindling fuel oil main jet on the Carburetor, enlarging air jet, waste gas on the carburetion and lead return tray, the defeated regulating mechanism of waste gas, the defeated regulating mechanism of air, vortex generator, modulation draught damper, open-shut linkage device and form.It is socket joint cylinder mesa structure that waste gas is led return tray, has a through hole in the side of large cylinder, in order to be connected with the waste gas conducting tube.Waste gas is led the interface pad place that return tray is installed in discharge manifold and baffler, and the roundlet tube inserts in the discharge manifold, and muffler pipe is inserted in the large cylinder, and the interface disc of baffler is connected with discharge manifold, and soon waste gas is led return tray and is fixedly clamped therein.The defeated regulating mechanism of waste gas is made up of waste gas conducting tube and waste gas metering-orifice sheet group.Every of waste gas metering-orifice sheet group all is the disk that waits external diameter, every circle centre position all has a through hole, but does not wait in the aperture of each sheet through hole, select the waste gas metering-orifice sheet of a respective aperture for use according to the variation of ambient temperature, be connected by fastening piece between the horizontal waste gas inlet of waste gas conducting tube and modulation draught damper.The defeated regulating mechanism of air by motor steam conduit, lubricant oil steam conduit, air converge conduit, air jet sheet group is formed.Air jet sheet group is that a plurality of disks of external diameter that wait are formed, every circle centre position all has a through hole, but does not wait in the aperture of each sheet through hole, select the air jet sheet of a respective aperture for use according to the variation of ambient temperature, the air jet sheet is connected air by fastening piece and converges between the vertical air inlet of conduit and modulation draught damper.The open-shut linkage device is made up of carburetor throttle rocking arm, modulation draught damper rocking arm, connecting rod.The closure rocking arm is connected by connecting rod with modulation draught damper rocking arm, and modulation draught damper rocking arm is connected with the valve rod of the fly valve of modulation draught damper.The modulation draught damper is made up of valve body, fly valve, filter gauze, vertical air inlet, horizontal waste gas inlet, air outlet.Fly valve is installed in the place, air outlet of valve body, and filter gauze covers on the converging channel place of vertical air inlet and horizontal waste gas inlet.Vortex generator is made up of annular outer cover body, annular inner housing.Form an annular air channel between the inside-and-outside ring housing, several jet grooves are being uniformly distributed along the circumference on annular inner housing, the axis of jet groove has the angle except that the diameter with ring, also has an angle of declination between while and horizontal line, make the gas by vortex generator become the stereo rotating eddy current, the suction port end of vortex generator forms airtight the connection with the air outlet of modulation draught damper.Vortex generator is installed between inlet manifold and the Carburetor.
Good effect of the present utility model: adopt behind the utility model under the constant condition of former design motivation performance, the new car fuel saving ratio is about 5%, and the fuel saving ratio of other situation car is 10～20%; Exhaust emissions harmful substance CO, HC are lower than existing GB, CO＜4.5%, and HC＜1000PPm is to the NO in the Abgasgesetz that is about to promulgation
XThe reduction of discharge amount more has positive effect.Except that fuel oil main jet and air jet, the component of former machine are not made any change.Remove the gas oil ratio to idling operation when mounted, do on Carburetor outside the simple debugging, being in operation does not increase and changes any programmed sequence of operations.Install easily simply, can be used for host country and steam on oil turbine and the part inlet vapor oil turbine.With seasonal variations, only need change tertiary air metering-orifice sheet and waste gas metering-orifice sheet in 1 year, just can realize annual fuel-economizing and tail gas pollutant emission index.
