Abstract

PURPOSE: To provide an exhaust gas purifying secondary air supply system for a cross flow engine provided at an air cleaner on the suction side thereof which system can promote combustion of unburnt gas in the engine by constituting the system such that secondary air is preheated within a secondary air supply passage thereof.
CONSTITUTION: Suction pipes 12 of an engine 9 extend upwardly from inside of banks 10, 11 and a connecting pipe 21 is disposed in a position between the suction pipes 12 to extend substantially in parallel with the suction pipes 12 and has an air cleanser 22 provided at the lower end thereof. A valve chamber 24 is provided adjacent to and forwardly of the air cleaner 22 and a reed valve 25 is disposed between the two which allows air to flow only in a direction from the air cleaner 22 into the valve chamber 24. Secondary air supply passages 27 are formed within cylinder heads 26 such that they extend across the cylinder heads 26 from the suction pipe 12 sides to exhaust pipes 13, 14. Each of the secondary air passages 27 has its one end 27a opened to the suction pipe 12 side of each bank 10, 11 and its other end 27b opened in the wall of an exhaust passage 28 of the engine.
