Abstract
An internal combustion engine possesses a reactor for afterburning of unburned constituents in the exhaust gas. The reactor includes a shell containing a heat-insulated, freely movable reactor chamber with at least one inlet nozzle extending freely through the shell and communicating with an outlet passage of the combustion engine. An outlet is also provided for escape of the exhaust gases from the reactor chamber.
Claims9
An internal combustion engine having an engine housing and having a reactor for afterburning of unburned constituents in the exhaust gas, the reactor having a shell with a periphery and containing a heat-insulated, reactor chamber connected thereto and being freely movable beyond the point of connection to the shell with at least one inlet nozzle extending freely through the shell and communicating with an outlet passage of the engine, and an outlet for escape of the exhaust gases from the reactor chamber, the inlet nozzle protruding freely into the outlet passage, and the shell having a portion around the inlet nozzle and in contact with the engine housing and being bolted at its periphery to the engine housing, and the inlet nozzle protruding into the outlet passage of the engine with clearance all around and being surrounded by a packing.
