Good question :)
I have the Jacobs Engine Exhaust Brake with my Cummins 400. It has a 2-4-6 cylinders selector switch with clutch and throttle switches.
You have an engine compression brake, not an exhaust brake. Yours cracks open the exhaust valves right at cylinder ignition, cuasing no power stroke. The 2-4-6 settings is how many cylinders being used for braking. Compression brakes are far more affective than exhaust brakes.
