Tính năng nổi bật & Lợi ích
More control inputs and outputs, capacity for additional features, additional monitoring capabilities, expansion capability for future enhancements
Adjustment free control of engine speed, customer defined operating characteristics, protection and warning system, optional display systems available
The electronic control system has additional capacity for future enhancements to ensure a long useful engine life.
Provides a smoother passage for improved exhaust gas flow to the turbocharger which leads to more usable energy and lower exhaust temperatures.
The C12 has the same physical size, same footprint, and the same connection points as the 3196 engine as well the same optional attachments.
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).
