Verfahren und Vorrichtung zur Abgasnachbehandlung in Verbrennungskraftmaschinen

摘要

Air in the intake (1) enters the engine (10) between the choke (6) and engine cylinder head (11) and the engine (10) is switched off via camshaft-controlled system into a prefered position so the combustion space (20) inlet and outlet valves (13) are open after an engine run off control system (12). Secondary air fed from pump (37) loads a multi-way valve, with one branch led off to the exhaust handling system (24). Secondary air is also fed to the intake (6). Secondary air can also be taken from the vehicle air reservoir or compressed air brake unit.
