WARTSILA CCM-20

Product Overview The WARTSILA CCM-20 Cylinder Control Module is a marine cylinder control unit for Wärtsilä UNIC engine control system, engineered for marine diesel and dual-fuel engine cylinder management, designed to comply with DNV marine type approval and IEC 60945 marine EMC standards. Built for cylinder injection control, combustion monitoring, engine safety interlock, this robust rack-mounted module withstands engine room salt mist, continuous vibration and wide temperature fluctuation, delivers stable 24/7 continuous operation, and serves as core cylinder control hardware for merchant vessels, offshore platforms and FPSOs equipped with Wärtsilä marine engines.

Featuring high-speed signal sampling channels, CAN bus communication interface, on-board signal processing circuit & front LED diagnostic indicators. It supports standard cabinet rack mounting, adapting to limited installation space inside marine engine control cabinets. The modular assembly allows separate replacement of the module without full engine shutdown, greatly reducing equipment downtime for service. Equipped with conformal coated circuit board, overvoltage/overcurrent protection & built-in fault diagnostic function, mature hardware structure prevents signal interference and guarantees dependable cylinder control performance during continuous duty.

For dependable cylinder injection control, combustion monitoring, engine safety interlock, CCM-20 manages fuel injection timing for each cylinder, captures cylinder pressure and knock signals, and executes safety interlock commands when abnormal cylinder conditions occur. Reliable cylinder injection control, combustion monitoring, engine safety interlock, premium marine-grade electronic components provide excellent shock and corrosion resistance, extending service life in harsh marine engine room working environments. Practical conformal coated circuit board, overvoltage/overcurrent protection & built-in fault diagnostic function, service technicians can read fault codes and verify cylinder operating status during routine vessel maintenance.

During continuous cylinder injection control, combustion monitoring, engine safety interlock, this cylinder control module is fully compatible with Wärtsilä UNIC engine control platforms and ESM-20 engine protection modules. Stable cylinder injection control, combustion monitoring, engine safety interlock, mature Wärtsilä marine cylinder control technology with easy spare parts replacement and convenient after-sales maintenance. Robust conformal coated circuit board, overvoltage/overcurrent protection & built-in fault diagnostic function, simplifies engine control cabinet layout and reduces installation workload for marine engine retrofitting and engine automation overhaul projects.
