Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
128 words
A charged internal combustion engine ( 1 ) including: (a) at least one stage of charging by a turbocharger ( 3 ); (b) at least one supplemental compressor ( 4 ) connected to the turbocharger; (c) an air filter assembly, wherein the air filter assembly includes the supplemental compressor ( 4 ); (d) an electric motor ( 5 ) drive for the supplemental compressor ( 4 ); and (e) at least one closing ( 11 ) or switching ( 8 ) means provided between the supplemental compressor ( 4 ) and the turbocharger ( 3 ), wherein an electronic control device ( 40 ) is present to regulate operation of the supplemental compressor ( 4 ) and the closing ( 11 ) or switching ( 8 ) means.
Claim 2
Dependent Claim
128 words
A charged internal combustion engine ( 1 ) including: (a) at least one stage of charging by a turbocharger ( 3 ); (b) at least one supplemental compressor ( 4 ) connected to the turbocharger; (c) an air filter assembly, wherein the air filter assembly includes the supplemental compressor ( 4 ); (d) an electric motor ( 5 ) drive for the supplemental compressor ( 4 ); and (e) at least one closing ( 11 ) or switching ( 8 ) means provided between the supplemental compressor ( 4 ) and the turbocharger ( 3 ), wherein an electronic control device ( 40 ) is present to regulate operation of the supplemental compressor ( 4 ) and the closing ( 11 ) or switching ( 8 ) means.
Claim 3
Dependent Claim
24 words
The charged internal combustion engine ( 1 ) as in claim 1 , wherein the supplemental compressor is integrated in an air filter casing.
Claim 4
Dependent Claim
