Patent ID: 7150272

Claim:
An arrangement for delivering EGR gas to a combustion engine, said arrangement comprising: a four-stroke internal combustion engine having multi-cylinders, each of said cylinders comprising: a combustion space, an associated piston, and at least one inlet valve and at least one exhaust valve ( 10 ) for controlling connection between the combustion space in the cylinder and an intake system and an exhaust system, respectively; and a rotatable camshaft ( 18 ) having a cam curve ( 23 ) having a first rising gradient ( 23 a ) configured to interact with a first cam follower ( 17 ) for operating the respective at least one exhaust valve ( 10 ) during a first opening and closing phase, the cam curve ( 23 ) being further configured to interact with a second cam follower ( 20 ) during a second opening and closing phase that is phase-offset in relation to the first opening and closing phase, the cam curve having a second rising gradient ( 23 b ) that interacts with both cam followers ( 17 , 20 ) during both opening phases of the exhaust valve ( 10 ), which connects the cylinder with the exhaust system during the induction stroke after the exhaust stroke is completed.
