Abstract:
An internal combustion engine having at least one cylinder, a turbocharger, an intercooler, an electronic control unit, and a compression release brake, said turbocharger for compressing intake air for delivery into the intercooler, and said intercooler for lowering the temperature of the compressed air from the turbocharger for delivery into an intake manifold of the engine, comprising:a compression release brake controller for engaging said compression release brake; an intercooler bypass assembly for automatically diverting at least a portion of the compressed air from the turbocharger directly into the intake manifold and around the intercooler upon receiving a bypass signal from the compression release brake controller; a fuel injection assembly which, upon receiving an injection signal from the engine electronic control unit, injects a small quantity of fuel into the cylinder during a compression stroke of the engine while said compression release brake is engaged.
