专利汇可以提供Afterburner for internal combustion engine专利检索，专利查询，专利分析的服务。并且An afterburning system for minimizing hydrocarbon and carbon monoxide, content left unburned in engine exhaust gases of an internal combustion engine. In the afterburning system, an improved afterburning stabilizer is provided including a porous enclosure for uniformly admixing an additional air-fuel mixture, which is burned to form a premixed flame therearound for anchoring the main combustion of the contaminated exhaust gases. A number of projections are mounted upon the porous enclosure for producing small disturbances in the flow of the exhaust gases and for acting as a stable heat source for the main combustion when the premixed flame is formed close to the tips thereof.，下面是Afterburner for internal combustion engine专利的具体信息内容。

权利要求

1. An afterburning system for minimizing hydrocarbon and carbon monoxide contents left unburned in engine exhaust gases of an internal combustion engine, comprising: reburning means having a reburning chamber for reburning the engine exhaust gases therein; reburning stabilizing means including mixing means having a porous enclosure, and heat source and turbulence producing means having a number of projections mounted upon said enclosure, for forming a premixed flame close to the tips of said projections to stabilize the reburning of the engine exhaust gases; and additional air-fuel mixture supplying means for supplying an additional air-fuel mixture to said reburning stabilizing means, whereby said porous enclosure uniformly admixes said additional air-fuel mixture while it is passing therethrough, and said projections produce small turbulences in the flow of the engine exhaust gases and act as a heat source, while heated by said premixed flame, for anchoring the reburning of the engine exhaust gases.

2. An afterburning system according to claim 1, further comprising flow rate control means for controlling flow rate of said additional air-fuel mixture in dependence upon the temperature in said reburning chamber to maintain said temperature at a predetermined level appropriate for effecting complete combustion of the engine exhaust gases.

3. An afterburning system according to claim 2, wherein said flow rate control means includes a throttle valve rotatably mounted in said additional air-fuel mixture supplying means for controlling the effective area therearound, a servo-motor for rotating said throttle valve when energized, a controller for controlling energization of said servo-motor, and a temperature sensor mounted in said reburning chamber for sensing the temperature therein to control the operation of said controller.

4. An afterburning system according to claim 1, wherein said additional air-fuel mixture supplying means includes additional air supplying means for supplying fresh air to said reburning stabilizing means, and additional fuel supplying means for supplying an optimum amount of atomized fuel to the flow of the fresh air.

5. An afterburning system according to claim 4, wherein said additional air supplying means includes a passage vented to the atmosphere and communicating with said reburning stabilizing means, and a blower mounted in said passage for sucking the fresh air into said reburning stabilizing means, and wherein said additional fuel supplying means includes a carburetor mounted on said passage.

6. An afterburning system according to claim 1, wherein said reburning stabilizing means has a generally spherical shape and is located within and upstream of said reburning chamber.

7. An afterburning system according to claim 6, wherein said projections and located externally of said porous enclosure.

8. An afterburning system according to claim 1, wherein the porous enclosure of said reburning stabilizing means defines said reburning chamber.

9. An afterburning system according to claim 8, wherein said projections are located internally of said porous enclosure.
