A firing deck () for an engine crankcase includes a firing side surface () and a coolant side surface (). A plurality of cylinder bores () are disposed through the firing deck () from the firing side surface () to the coolant side surface (). The cylinder bores () form a centerline defining an intake side () of the firing deck () and an exhaust side () of the firing deck. A plurality of bosses () through the deck () from the firing side surface () to the coolant side surface () are disposed around each cylinder bore (). A plurality of anti-distortion projections () are disposed on the coolant side surface () of the firing deck () and provide the firing deck with a varied thickness. The anti-distortion projections () are disposed on both the intake side () and the exhaust side () of the firing deck ().

A control system for engine braking for a vehicle powered by a turbocharged engine uses a supercharger to assist a turbocharger compressor to boost turbocharger air flow into the engine cylinders. An engine driven air pumping device draws ambient air, or alternately exhaust gas through the pump inlet, compresses the air, and delivers the compressed air through the pump outlet to the turbocharger compressor inlet or alternately the turbocharger compressor outlet. The increased air flow into the cylinders and out of the cylinder exhaust valves increases retarding power of the vehicle.
