<p>PURPOSE:To certainly regenerate a particulate filter by starting the fuel spark plug of a combustor, outside-air introducing means, and a fuel feeding means when the pressure signal value exceeds a prescribed value. CONSTITUTION:The pressure on the inlet side of a particulate filter 2 is always detected by a pressure sensor 4, and a signal is sent into a controller 12. Said signal valve increases in proportion to the pressure, and when the signal value increases over a standard value, a blower 7 is put into electric conduction by the controller 12, and outside air is supplied into an air chamber 5 from an air taking-in duct 6, and the outside air is preheated by the exhaust gas which passes through the outside of a housing 3. The outside air is supplied into a carburetor 16 and a combustion chamber 17 through the air port of a combustion cylinder 19 from the air chamber 5.</p> |
