The invention relates to mechanical engineering, in particular to exhaust gas emission reduction systems of internal combustion engines.

The purpose of the invention is to increase the efficiency and efficiency of cleaning exhaust gases.

Fig, i is a diagram of the proposed system; in fig. 2 shows section A-A in FIG. five.

The system consists of a catalytic converter with housing 1 reactor 2, the output cavity 3 is liquid

neutralizer 4 with a filled with its | 5 cuttings 13, equipped with a reverse clathing fluid 5 with a container and an inlet pipe 6 and an evaporator. The catalytic converter case 1 is double-walled, cavity 7 between which is partly filled with 20 liquids .. The evaporator is located in cavity 7 and filled as tubes 8 installed in the fluid layer communicated from one side of the catalytic converter 25 a on the other hand, with the inlet of the neutralizer 4,

The cavity 7 of the evaporator is connected to the intake pipe of the engine channel 9, leaving the mixer 10, 30 and float chambers 1 1 connected to it, regulating the level of liquids. The cavity 7 is divided by pomopda partitions 12 into two parts, partially filled with dissimilar liquids with MI (for example, water and alcohol), and the cords from the parts are connected through additional pipes 13 to the channel 9 of the vapor from the evaporator. In the additional connections 3, check valves 4 are placed.

The system works as follows.

The engine exhaust gases are fed into the reactor 2 of the catalytic Neipan 14, flow into mixer 10 and from channel 9 through the engine inlet pipe of its internal wound, leading to a decrease in the content of exhaust gases in the nitrogen oxides, reducing the maximum temperature of the cycle, soot emission in exhaust gases and replacing fuel of petroleum origin.

The cooling of exhaust gases in an evaporator heater located in the double walls of the catalytic housing 1, not the catalyzer, separated by a partition, is made deeper due to the high latent heat of evaporation of alcohols relative to water. The latter makes it possible to dramatically increase the efficiency of their purification in a liquid neutralizer.

Claims (1)

St. No. 1044802, which is related to the fact that, in order to increase the efficiency and efficiency of the exhaust gas cleaning, the cavity is melody with double walls of cataloids a catalytic converter, where they are purified from a gaseous-.5 lytic converter of separated products of incomplete combustion. Procat catalyst bed 2,. exhaust gases enter the tubes by means of a partition into two parts filled with dissimilar liquids, each of which is connected through additional pipes to the vapor supply channel from the evaporator. 8, being in a layer of water and alcohol and gaseous fluid of the X phases of these substances, evaporate them and heat the vapors while cooling. The exhaust gases coming out of the cavity 3 of the evaporator heater, through the pipe 6 enters the liquid neutralizer 4, where effective cleaning of soot, sulfur oxides and other toxic components takes place, and is released into the atmosphere at the outlet of the neutralizer 4. In turn, the water and alcohol vapors formed and heated in the evaporator-heater, via additional paths 14, enter the mixer 10 and from it, through channel 9, into the inlet pipeline of the engine of its wound, resulting in a decrease in the content of exhaust gases in the exhaust gas nitrogen, reducing the maximum cycle temperature, emissions of soot in the exhaust gases and replacing fuel of petroleum origin. The cooling of exhaust gases in an evaporator heater located in the double walls of the catalytic housing 1, not the catalyzer, separated by a partition, is made deeper due to the high latent heat of evaporation of alcohols relative to water. The latter makes it possible to dramatically increase the efficiency of their purification in a liquid neutralizer. Formula of о.б р et e and Exhaust gas emission reduction system of an internal combustion engine according to aut.
