Abstract: 1374877 Treating exhaust gas DAIMLERBENZ AG 17 Nov 1972 [26 Nov 1971] 53230/72 Heading F1B A reactor for burning exhaust gases is provided with a supplementary air and fuel arrangement and an ignition device, and has a non-return valve disposed in a line supplying a mixture of fuel and air to the burning space of the reactor. Exhaust gases passing along a pipe 1 enter a burning space 2, which receives a fuel-air mixture from a pipe 4, the end 6 of which is open to atmosphere and into which fuel is pumped through a nozzle 11. Downstream of the nozzle 11 is a non-return valve 5, followed by an igniter 14. The part of the pipe 4 preceding the junction of the pipes 1 and 4 is close to, and may be welded to the pipe 1 so that the mixture is heated by the exhaust gases. A shut-off valve 15 is provided in the pipe 4 and is opened only at low-load engine operating conditions i.e. at starting or idling, and is controlled by the pressure in the induction manifold or the engine speed. In a modification the fuel is supplied to the line 4 by a float-type carburetter, in which the flow of fuel is controlled by a needle valve, the position of which is determined in dependence upon manifold pressure or engine speed. The non-return valve 5 may be positioned upstream of the point in the line 4 where fuel is admitted. Fuel economy is achieved with the device since the air-fuel mixture is only drawn into the burning space 2 when the pressure in the exhaust pipe is less than atmospheric pressure.
