Advantages and Features
ADEM III Control System
More control inputs and outputs, capacity for additional features, additional monitoring capabilities, expansion capability for future enhancementsMost Advanced Electronic Control System
Adjustment free control of engine speed, customer defined operating characteristics, protection and warning system, optional display systems availableFuture Enhancement Capability
The electronic control system has additional capacity for future enhancements to ensure a long useful engine lifeRedesigned Exhaust Manifold
Provides a smoother passage for improved exhaust gas flow to the turbocharger which leads to more usable energy and lower exhaust temperatures.Easy Replacement for 3196
The C12 has the same physical size, same footprint, and the same connection points as the 3196 engine as well the same optional attachments.Optional Monitoring System
Caterpillar offers several “plug and play” monitoring systems which display everything from the basic engine operating parameters to engine load factor and trip totals. Ask your local Caterpillar dealer for additional information on our Marine Power Display (MPD), Marine Analog Power Display (MAPD), and our Engine Vision Display (EVD).Product Support
