SERIES 60 SERVICE MANUAL
Energizing the engine brake effectively converts a power-producing diesel engine into a
power-absorbing air compressor. This is accomplished through motion transfer using a
master-slave piston arrangement which opens cylinder exhaust valves near the top of the normal
compression stroke, releasing the compressed cylinder charge to exhaust. See Figure 1-415.
