Description

Energy-saving, silencing exhaust apparatus for internal combustion engine

The utility model relates to a kind of combustion engine energy-saving and falls dirty cooling noise reducing exhaust device, and it comprises the corrugation rows tracheae that links to each other with exhaust manifold for internal combustion engine, with the air heating jar, blowdown pipe and the aeration valve that link to each other with the corrugation rows tracheae.

Chinese patent 89215055.6 discloses a kind of Purification of IC Exhaustive Gas sound-attenuating system that is specially adapted to, for reaching the purpose that reduces delivery temperature, the formation of this technological scheme is to be connected in series cooling water tank successively and radiating fin has been installed on muffler shell in the middle of the exhaust silencer, comprise with internal combustion engine exhaust silencer extension gas and proper proportion air mixing after send back to the combustion chambers of internal combustion engines recycling.The one deficiency is that the main cooling water tank that is connected in series in the middle of the silencing apparatus that relies on of exhaust cooling is realized, because the water of cooling silencing apparatus derives from engine cooling water, utilize engine cooling water to cool off the high-temperature gas of discharge, cause engine temperature too high easily, factors such as water usage increase; Its two deficiency is a welding processing radiating fin on the muffler shell, because housing is originally as round body type, radiating fin welds difficult moulding, adds to that workpiece welds easy damage silencing apparatus global shape mutually and owing to weld seam too much causes the steel variation, influences product working life; Its three deficiency is that the air mixing of drawing part waste gas and proper proportion in exhaust silencer is utilized again.Carbon dioxide in the waste gas of Hui Shouing just sends back to the firing chamber not by separating like this, and also the powder or the carbon distribution of effective amount also enter in the internal-combustion engine simultaneously, and its result makes the inflammable gas that reclaims in the effulent reduce.

The purpose of this utility model is to overcome above-mentioned deficiency of the prior art and a kind of delivery temperature, reduction exhaust emission material of reducing effectively is provided, and dirty cooling noise reducing exhaust device falls in the combustion engine energy-saving with better energy-saving effect.

Combustion engine energy-saving provided by the utility model falls dirty cooling noise reducing exhaust device and mainly is made up of flange plate, aeration valve, blowdown pipe, outlet pipe fastening flange, air heating jar, air-filtering assembly, flexible pipe and corrugation rows tracheae.Wherein the air heating jar is located at corrugation rows tracheae intermediate portion, and the air-filtering assembly is connected with the air heating jar, also is provided with the outlet pipe fastening flange that is communicated with intake and exhaust manifold on the corrugation rows tracheae, and aeration valve and flange plate are connected.Blowdown pipe one end is communicated with aeration valve, and the other end is communicated with the corrugation rows tracheae.Flexible pipe is connected with the water tank overflow mouth of a river before the motor.When internal combustion engine operation, heat in the I. C. engine exhaust is with the air heating in the air heating jar, air enters inlet manifold of IC engine by the further heating of pipeline in the outlet pipe, former excessive water vapor to atmosphere also is mixed into intake manifold by flexible pipe and hot air in the engine water tank, regulate the air fuel ratio of mixed gas and the atomizing effect of enhancing mixed gas fuel oil, reach fuel-economizing and fall dirty effect.The bellows radiator is compared with outlet pipe, and heat dispersing surface increases relatively, and the air that passes through in the corrugation rows tracheae has also absorbed the heat the exhaust, has reduced engine exhaust temperature effectively.The decline of delivery temperature impels the corresponding contraction of exhaust gas volume to diminish, and reduces exhaust back pressure, makes exhaust unobstructed, improves engine power performance and the Economy of improving motor.Waste gas dwindles in corrugation rows tracheae inner volume, also helps to reduce the expansion sound wave that high-temperature gas causes in the pipe, reduces exhaust noise; Delivery temperature reduces significantly, helps the fire safety of vehicle, more helps oil field, forest operation vehicle.

The utility model compared with prior art has safety, fuel-economizing, falls dirt, advantage such as cooling and exhaust noise are low.

Fig. 1 is the structural representation of device described in the utility model.

Below in conjunction with accompanying drawing, the utility model specific embodiment is described in detail.

With reference to Fig. 1, dirty cooling noise reducing exhaust device falls in combustion engine energy-saving of the present utility model, mainly is made up of aeration valve 1, flange plate 2, blowdown pipe 3, outlet pipe fastening flange 4, corrugation rows tracheae 5, air heating jar 6, air-filtering assembly 7 and flexible pipe 8.Air heating jar 6 is located at corrugation rows tracheae 5 intermediate portions, and air heating jar 6 is provided with the blowdown pipe of connecting with the special-purpose seat of Carburetor flange plate 23.The exhaust port of corrugation rows tracheae 5 connects the silencing apparatus (not shown), filters assembly 7 and links to each other with overflow on the engine radiating water tank, and corrugation rows tracheae 5 is provided with the outlet pipe fastening flange 4 that joins with intake and exhaust manifold 9.Air-filtering assembly 7 is connected with air heating jar 6, and aeration valve 1 is connected with flange plate 2.Fresh air enters heating tank 6 through air-filtering assembly 7, water vapor enters heating tank 6 from the engine radiating water tank is suitable for reading through flexible pipe 8, air-filtering assembly 7, after the heating, enters blowdown pipe 3 and sends into Carburetor special flange dish 2, so that strengthen the fuel of internal combustion engine atomizing effect, reach the purpose of fuel-economizing.
