专利摘要:
1475001 Afterburners HONDA GIKEN KOGYO KK 17 July 1974 [18 July 1973] 31720/74 Heading F4B [Also in Division F1] In an IC engine having auxiliary combustion chambers 5 with spark plugs 6 opening into the main cylinders 3 through flame ports 4, preliminary after-burner chambers 18 are each connected to the exhaust ports 8 of two cylinders with different timing and open into a main afterburner chamber 15 of substantially greater volume than each chamber 18. The chamber 15 is 5-8 times the volume of the individual chambers 18 and has heat insulated walls 17. A rich mixture is fed to the auxiliary chambers 5 and is preheated from the afterburner 15, while a lean fuel/air mixture fed to the main cylinders 3 may also be preheated by the afterburner. The overall fuel/air mixture is sufficiently lean for afterburning without additional air, and the mouth of each preliminary after burner chamber directs exhaust gases towards one end of the main chamber 15, the exhaust outlet 19 opening from its other end.

is connected to the exhaust port 12 via the exhaust valve 13.
The space between the bays of the liners is occupied by the body of the reaction chamber 14 of the thermoreactor for the afterburning of exhaust gases. The upper part of the reaction chamber is a common wall with the first pipe 7. The second pipeline Go is also located above the reaction chamber 14 and also has a common wall with it.
The reaction chamber 14 has four additional reaction chambers 15 in which exhaust ports are made that are directed towards the front of the main reaction chamber 14 The exhaust pipe 16 is directed from the rear of the main reaction chamber 14 to the silencer (not shown). Each additional reaction chamber 15 is connected to two adjacent cylinders so that eight chambers require four chambers 15.
The engine works in the following way. /
Atmospheric air enters engine 1 through main carburet 6 and additional carburetor 9. The poor mixture formed in main carburetor 6 is heated and evaporated in the first pipe 7 and enters main combustion chambers 2. The mixture formed in additional carburetor 9 is rich and vaporizes in the second conduit 10 and enters the prechambers 3. At the end of the compression stroke, the mixture in the prechamber 3 ignites with the spark plug 5 and forms a flame jet, which through the flame channel 4 jo steps into the main combustion chamber audio 2 and ignites the lean this chamber. During the exhaust course, exhaust gases are released through the exhaust
channels 12 to the additional reaction chambers 15. The exhaust gases then expand and lose speed. After that, the gases enter the main reaction chamber 14. The final release of gases to the atmosphere is effected through the exhaust pipe 16. The use of heating of the pipelines that supply the mixture to the main combustion chamber and to the fork to measure improves mixing and increases the combustion efficiency, thereby reducing emission of products of incomplete combustion with exhaust gases.

Claims (2)
[1]
1. A chambered internal combustion engine with spark ignition and a V-shaped cylinder arrangement, containing a first pipeline for supplying a lean fuel-air mixture to the combustion chamber, a second pipeline for supplying a rich fuel-air mixture to Forkamer and a reaction chamber placed between rows of cylinders, communicated with the exhaust pipe and connected through an additional chamber and exhaust channel to the combustion chamber, about the aphid {ay, with the aim of reducing the content of toxic substances in the exhaust gases by overheating mixture, the second conduit is disposed above the reaction chamber
and has a common wall with it.
