Summary of the invention
The purpose of this invention is to provide a kind of heat energy that can make full use of engine exhaust, improve the device for generating gas using residual heat of engine of engine thermal efficiency.
The present invention is that the high-temp waste gas that utilizes motor to discharge heats carbon, make carbon dioxide and water vapor and carbon generation reduction reaction in the part gas of waste gas, generate carbon monoxide and hydrogen, after filtering cooling, enter engine combustion by suction tude again, to reach the purpose that improves heat utilization efficiency and fuel-economizing.
Its chemical reaction theory is:
CO
2+C→2CO
H
2O+C→H
2+CO
The atomic weight 12 of carbon, the atomic weight 16 of oxygen, the atomic weight of hydrogen are 1, and promptly every kg of carbon can produce about 3.6 kilograms coal gas, and the gasoline combustion calorific value is 4.6 * 10
7J/kg, coal gas are 3.9 * 10
7J/kg, the coal gas that promptly per 1 kilogram of carbon produces is equivalent to the energy of 3 kilograms of gasoline.In actual use, use coke as reducing agent, because of harmful components such as it is not phosphorous, sulphur, and price lower (because its price only is 1/5 of a gasoline, so every in theory consumption 1 yuan coke can be saved 15 yuan of oily money).Petrol engine can be controlled at the circulating load of waste gas below 30% in actual the use, and the circulating load of the waste gas of diesel engine is controlled at 10% and is advisable.
Device concrete structure of the present invention is: be installed in the outlet pipe (2) on the motor (1) conduit (15) is installed, conduit leads to reaction tube (22), charging hole (3) and end cover (16) are arranged on the reaction tube, filter screen (21) is arranged at the bottom in the reaction tube, dedusting mouth (17) and sealing cover (18) are arranged at the bottom, steam outlet pipe (5) is arranged under the filter screen (21), there is prefilter (20) ingress of this steam outlet pipe, steam outlet pipe (5) links to each other with cooler (6), cooler is installed on cooling water radiator (7) afterwards or the side, and CO sensor (4) is installed on the steam outlet pipe (5).Display instrument for automobile carbon monoxide transducer (4) is installed on the instrument desk, as whether adding whether normal foundation of carbon and work.
Reaction tube relies on anchor plate (23) to be fixed on the outlet pipe (2).On the suction tude (12) between engine air throttle (14) and the empty filter (13), a trunnion (11) is housed, links to each other by pipeline (8) between trunnion (11) and the cooler.The valve (10) of fine cleaner (9) and control ventilation size is installed on the pipeline (8).
The present invention is that the high-temp waste gas that utilizes motor to discharge heats carbon, allows carbon dioxide (CO in the portion gas
2) and water vapor (H
2O), generate carbon monoxide (CO) and hydrogen (H with carbon generation reduction reaction
2) after filtration after the cooling, enter engine combustion by suction tude, to reach the purpose that improves heat utilization efficiency and fuel-economizing.The present invention can reduce exhaust pollution and noise, and its fuel saving ratio can reach more than 50% simultaneously.

Among the figure, 1-motor, 2-outlet pipe, 3-charging hole, the 4-carbon monoxide transducer, 5-steam outlet pipe, 6-cooler, 7-radiator, the 8-pipeline, 9-fine cleaner, 10-valve, 11-trunnion, the 12-suction tude, the empty filter of 13-, 14-closure, 15-conduit, the 16-end cover, 17-dedusting mouth, 18-sealing cover, 19-air outlet, the 20-prefilter, 21-filter screen, 22-reaction tube, 23-anchor plate.
Embodiment
As shown in the figure, the concrete formation of apparatus of the present invention is: being installed in the outlet pipe 2 on the motor 1 has conduit 15, conduit leads to reaction tube 22, charging hole 3 is arranged on the reaction tube, end cover 16 on the charging hole 3, filter screen 21 is arranged at the bottom in the reaction tube, dedusting mouth 17 and sealing cover 18 are arranged at the bottom, reaction tube relies on anchor plate 23 to be fixed on the outlet pipe 2, filter screen has steam outlet pipe 5 21 times, there is prefilter 20 ingress of this steam outlet pipe, steam outlet pipe links to each other with cooler 6, cooler is installed on (or side) after the cooling water radiator 7, one trunnion 11 is housed on the suction tude 12 between closure 14 and the empty filter 13, links to each other by pipeline 8 between trunnion 11 and the cooler 6, the valve 10 of fine cleaner 9 and control ventilation size is installed on the pipeline 8, whether normally display instrument for automobile carbon monoxide transducer 4 is installed on the instrument desk, as adding carbon and work foundation.
Its working principle is: behind the engine running, the part high-temperature gas of its discharge enters reaction tube 22 through conduit 15, and (it is higher to be facing to the purpose of each cylinder that each work cycle of motor begins preceding half process temperature of exhaust respectively with conduit, because volume increases after the reduction reaction, add the influence of other cylinder, exhaust later stage pressure is low, the slow low temperature waste gas of the velocity of discharge just seldom enters reaction tube, therefore not influencing reaction velocity) most of waste gas is by the interlayer between reaction tube 22 and the outlet pipe 2, enter atmosphere through exporting 19 by silencing apparatus again, carbon in the reaction tube heats inside and outside this and reaches reaction temperature rapidly, the CO in the waste gas
2And H
2O begin with reaction tube in carbon reaction, generate CO and H
2, reacted mixed gas through prefilter 20 by pipeline 5 enter cooler 6 again through piping 8 and fine cleaner 9 and control valve 10, after trunnion 11 enters motor master suction tude 12, enters engine combustion work at last, begin next circulation.The purpose that adds with trunnion 11 is the suction that increases waste gas, and cooled mixed gas and new Air mixing temperature are comparatively desirable in the time of 100 ℃～200 ℃, and this is beneficial to after the gasoline injection decomposition of gasifying rapidly of the oil droplet of larger particles, is beneficial to burning.The unlatching size of control valve 10 has demand to decide according to motor, as need based on Economy, then open bigger, as need power be main then open smaller.The carbon that uses should not contain impurity such as p and s.
