Abstract

1355267 Purifying I C engine exhaust gases TOYO KOGYO CO Ltd 23 July 1971 [24 July 1970 31 July 1970(4)] 34635/71 Heading F1B A jacket 10 surrounding the shell 6 of an afterburner 5 is supplied with cooling air and air is also supplied to the afterburner chamber 7. The flow of cooling air is controlled in response to the temperature of the shell 6, the engine body, the engine cooling medium or the jacket casing 9 and/or the speed of the engine and the flow of afterburning air may be controlled in response to engine speed. The air may be supplied by a single engine-driven pump 13 or separate pumps may supply the cooling and afterburning air. In the embodiment shown, the flow of air to the engine exhaust passage 8 is controlled by a valve 19 which is open in a lower engine speed range and closed above the range, the air flowing through a non-return valve 20. Cooling air flows to the jacket 10 through a valve 21 at a rate proportional to engine speed in a lower speed range when a valve 27, which is open above a predetermined temperature detected by a sensor 29a, is open. Above the speed range a valve 22 is open and the valve 19 closed. A valve 24 releases a proportion of the air to the atmosphere at a predetermined air pressure. A non-return valve 25 prevents the flow of exhaust gas from the chamber 7 to the cooling air supply passages. The valve 27, Fig. 12 (not shown), may be disposed between the jacket and both valves 21 and 22. The valves 19 to 21 may be combined in a single assembly, Fig. 15, the valve member 39 and seat 42b providing the valve 19, the valve member 43 the valve 20, the opening 39a and valve member 40 the valve 21 and the valve member 39 and seat 45 the valve 22. A solenoid valve 46 is opened by an engine speed detector 47 below a certain speed and the suction in the engine intake passage 3 is applied to the diaphragm 36 to seat the member 39 on the seat 45. In this condition, with the valve 24 closed, air flows past the valve members 40 and 43 and with the valve 24 open the air escapes to atmosphere. With the valve 46 closed the valve member 39 is seated on the seat 42b and unless the valve 24 is open all the air flows to the passage 18 communicating with the jacket 10. Various other relationships between the air flows to the jacket 10, the chamber 7 and the atmosphere are described.
