Abstract
In an internal combustion engine equipped with a turbocharger and a compression release engine brake, excessive stress in the engine and engine brake during operation of the engine brake at relatively high engine speeds is prevented by limiting the intake manifold pressure increase produced by the turbocharger, particularly at higher engine speeds. When the engine brake is turned on, a pressure sensor is enabled to sense the gas pressure in the intake manifold. When the pressure sensor detects that the intake manifold pressure is above a predetermined threshold level, the pressure sensor applies gas from the intake manifold to a pneumatic actuator. The pneumatic actuator opens a pressure relief valve which releases gas from the intake manifold to the ambient atmosphere.
