CONT

Simply stated, energizing the [Jacobs] Engine Brake effectively converts a power producing diesel engine into a power absorbing air compressor. This is accomplished when desired [by a mechanism] which opens the cylinder exhaust valves near the top of the normal power stroke releasing the compressed cylinder charge to exhaust. [This results in] a net energy loss since the work done in compressing the cylinder charge is not returned during the expansion process.
