Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
105 words
An exhaust gas recirculation system for an internal combustion engine by which a portion of exhaust gases produced by the engine is recirculated from an exhaust line of the engine into an intake line of the engine, said exhaust gas recirculation system comprising an exhaust gas recirculation line connecting the exhaust line of the engine to the intake line of the engine, a pressure differential means for drawing a secondary flow from said recirculation line into a primary flow in said intake line, and an ejector connected to a source of high pressure air, said ejector having a discharge end disposed in said recirculation line.
Claim 2
Dependent Claim
105 words
An exhaust gas recirculation system for an internal combustion engine by which a portion of exhaust gases produced by the engine is recirculated from an exhaust line of the engine into an intake line of the engine, said exhaust gas recirculation system comprising an exhaust gas recirculation line connecting the exhaust line of the engine to the intake line of the engine, a pressure differential means for drawing a secondary flow from said recirculation line into a primary flow in said intake line, and an ejector connected to a source of high pressure air, said ejector having a discharge end disposed in said recirculation line.
Claim 3
Dependent Claim
21 words
An exhaust gas recirculation system according to claim 1, wherein said pressure differential means comprises a venturi in said intake line.
Claim 4
Dependent Claim
48 words
An exhaust gas recirculation system according to claim 2, wherein said ejector is a lobed mixer type ejector which mixes exhaust gas in said exhaust gas recirculation line with air from said source of high pressure air upstream of a diffuser section of the exhaust gas recirculation line.
Claim 5
Dependent Claim
26 words
An exhaust gas recirculation system according to claim 1, wherein said pressure differential means comprises a second ejector, said second ejector extending into said intake line.
Claim 6
Dependent Claim
51 words
An exhaust gas recirculation system according to claim 4, wherein said second ejector is a lobed mixer type ejector which mixes said secondary flow from said exhaust gas recirculation line with said primary flow in a portion of said intake line located upstream of a diffuser section of the intake line.
Claim 7
Dependent Claim
48 words
An exhaust gas recirculation system according to claim 1, wherein said ejector is a lobed mixer type ejector which mixes exhaust gas in said exhaust gas recirculation line with air from said source of high pressure air upstream of a diffuser section of the exhaust gas recirculation line.
Claim 8
Dependent Claim
64 words
An exhaust gas recirculation system according to claim 6, wherein said source of high pressure air is a compressor of an exhaust gas powered turbocharger having at least one turbine, said exhaust line being connected to said at least one turbine downstream of said exhaust gas recirculation line, and said exhaust gas recirculation line being connected to the intake line downstream of said compressor.
Claim 9
Dependent Claim
64 words
An exhaust gas recirculation system according to claim 1, wherein said source of high pressure air is a compressor of an exhaust gas powered turbocharger having at least one turbine, said exhaust line being connected to said at least one turbine downstream of said exhaust gas recirculation line, and said exhaust gas recirculation line being connected to the intake line downstream of said compressor.
