Abstract
A controlled exhaust brake for an engine comprises an exhaust restrictor located in an exhaust system downstream of an exhaust manifold of an engine. An actuator operably associated with the restrictor adjusts the restrictor. A pressure sensor operably associated with the exhaust manifold senses pressure in the exhaust manifold. A controller determines a set pressure in the exhaust manifold correlated with speed of the engine. The controller is in communication with the pressure sensor and the actuator, and causes adjustment of the restrictor in order to achieve and maintain the set pressure in the exhaust manifold.
