摘要： A cylinder head casting for a three cylinder engine having a dedicated exhaust gas recirculation cylinder and two non-dedicated cylinders, includes three combustion chamber upper wall portions. First and second exhaust ports/runners extend from two of the three combustion chamber upper wall portions, respectively, for the non-dedicated cylinders and are paired together prior to a first common breakout at an exhaust flange in a side face of the cylinder head. A third exhaust port/runner extends from the other of the three combustion chamber upper wall portions corresponding to the dedicated EGR cylinder remains separated from the first and second exhaust port runners until a separate second breakout at the exhaust flange.

摘要： An engine control system includes an internal combustion engine including a plurality of cylinders. An intake manifold is connected to the internal combustion engine. An exhaust manifold is connected to the internal combustion engine. A supercharger is connected to an air intake passage and the intake manifold and includes a variable speed drive. A throttle valve is disposed in the air intake passage. An exhaust passage is in connection with the exhaust manifold. A passive selective catalytic reduction catalyst system is in communication with the exhaust passage. An exhaust gas recirculation passage is in communication with the exhaust passage and the air intake passage and includes an exhaust gas recirculation valve. A controller controls the variable speed drive of the supercharger and the throttle valve and the exhaust gas recirculation valve based upon engine conditions.

摘要： A tensioner device, includes a housing defining a cylindrical bore. A plunger is disposed in the bore and has a non-cylindrical outer surface. A spring is engaged with the plunger for biasing the plunger in an outward direction and an oil passage is in communication with the cylindrical bore for delivering pressurized oil to the bore. The non-cylindrical outer surface provides hydraulic clearance areas between the plunger and the bore to provide improved damping without high damping force.
