[Title <strong>of</strong> the Invention]<br />
Internal combustion engine equipped with exhaust gas filter and the process <strong>of</strong> its operation<br />
[Claims]<br />
1. Internal combustion engine equipped with supercharger flap (6) and …pressure wave<br />
supercharger (7), wherein an exhaust gas filter (18) is placed in the exhaust pipe<br />
up-stream (11) <strong>of</strong> the pressure wave supercharger (7).<br />
2. Process <strong>of</strong> operating the internal combustion engine equipped with supercharger flap (6)<br />
and…pressure wave supercharger (7) and placing a exhaust gas filter (18) in the exhaust<br />
pipe up-stream (11) <strong>of</strong> the pressure wave supercharger (7), characterized by an increase in<br />
the fuel supply to the internal combustion engine when the exhaust filter is clogged.<br />
[Excerpt from Detail Description <strong>of</strong> the Invention and Drawings]<br />
The primary invention concerns the internal combustion engine equipped with exhaust gas<br />
filter. If the exhaust filter is placed down-stream from the pressure wave supercharger, the<br />
engine could stall when the filter is clogged. The filter, thus, was placed on the up-stream side.<br />
The second invention concerns the operation <strong>of</strong> the internal combustion engine equipped<br />
with the exhaust filter. When the exhaust gas filter is clogged, it is necessary to burn <strong>of</strong>f the<br />
trapping <strong>for</strong>m the filter. In order to raise the exhaust gas above the combustion temperature, an<br />
over supply <strong>of</strong> the fuel is required while the engine is running.<br />
[Explanation]<br />
In the exhaust filter <strong>for</strong> the internal combustion engine <strong>of</strong> the specified invention (Claim 1),<br />
its function cannot be effected or maintained. The related invention (Claim 2) is directed to<br />
operate the internal combustion engine so that the temperature <strong>of</strong> the exhaust gas is raised in<br />
order to remove the clogging. Affecting an external <strong>for</strong>ce to the filter allows it to maintain or<br />
activate its function. The two inventions, there<strong>for</strong>e, are the product and the process <strong>of</strong> handling<br />
the product.<br />
