　　2223B001300 C3/C5 Other Names:

　　Communication Module 2223B001300 C3/C5

　　2223B001300 C3/C5 Input/Output Module

　　Analog Module 2223B001300 C3/C5

　　Core Functions and System Architecture

　　Module Positioning: The 2223B001300 C3/C5 is a core component of the Wärtsilä RT-flex series electronic fuel injection diesel engine control system. Each cylinder is equipped with an independent module, responsible for handling key functions such as fuel injection, exhaust valve control, and common rail pressure management for that cylinder. The module communicates with the main control module (MCM) via an internal CAN bus and is integrated into the WECS-9520/9500 control system.

　　Technical Principle: Based on high-pressure common rail technology, the traditional camshaft and fuel pump are eliminated. A servo oil-driven high-speed solenoid valve achieves precise control of fuel injection and exhaust valves. The module calculates injection timing using crankshaft angle sensor signals, combining VIT (Variable Injection Timing) and FQS (Fuel Quality Setting) to optimize the combustion process. It supports multi-stage injection strategies such as pre-injection and post-injection, improving fuel economy and reducing emissions.

　　Technical Features:

　　High-Pressure Control: Common rail fuel pressure 600-900 bar, servo oil pressure 80-190 bar. The fuel pump flow is dynamically adjusted via an electric actuator to ensure stable pressure.

　　Intelligent Combustion Control (ICC): Real-time analysis of parameters such as injection timing, exhaust valve angle, and compression pressure automatically optimizes cylinder load balance, reducing fuel consumption (full load range optimization) and emissions (NOx and other pollutants), and improving combustion efficiency.

　　Fault Redundancy Design: Supports online backup module replacement. Spare modules are pre-installed in the E90 control room communication box. After data synchronization, faulty modules can be directly replaced without re-downloading software, ensuring continuous operation of the main unit. Software Management: Supports automatic software synchronization. When the module is connected to the E90 backup box, the system automatically triggers the software download process. A single flashing SW LED indicator indicates download in progress, while a solid light indicates completion. The module's software version must be consistent with the host software to avoid "software version mismatch" alarms.

　　Communication and Redundancy: Employs a dual-power supply design to ensure controllable power outage risks. Communicates with remote control systems, alarm systems, speed controllers, etc., via CAN bus, supporting secondary/important alarm classification (e.g., cylinder shutdown alarm is considered an important alarm).

　　Application Scenarios and Operating Logic:

　　Marine Main Engine Applications: Widely used in Wärtsilä RT-flex series diesel engines (e.g., 6RT-Flex48T-D), suitable for container ships, LNG carriers, etc. For example, in a case of main engine failure on a 1042TEU container ship, a faulty 2223B001300 C3/C5 module caused cylinder shutdown; power was restored by quickly replacing the module, preventing accidents in narrow waterways.

　　Intelligent Features: Integrates the flexView human-machine interface, displaying real-time parameters such as main engine speed, common rail pressure, fuel injection curve, and exhaust valve status. Supports remote parameter adjustment and fault diagnosis. Modules support online replacement; spare modules can be used immediately after software synchronization in the E90 chassis.

　　Maintenance Convenience: Modular design facilitates quick replacement, supporting power-off reset, software version verification (via flexView's "SW-Info" function), and periodic synchronization (version and PACA-CRC checksum verification every 3 months).

　　Control Flow:

　　Fuel Injection: The 2223B001300 C3/C5 calculates the injection angle based on crankshaft angle signals, VIT (Variable Injection Timing), and FQS (Fuel Quantity Setting). It controls the injector action via a common rail solenoid valve, supporting flexible activation of 1-3 injectors per cylinder (1 under low load, 3 under high load).

　　Exhaust Valve Control: Servo hydraulic drives the exhaust valve. The 2223B001300 C3/C5 calculates the opening/closing angle, compensates for mechanical delays (such as dead time), and provides real-time status feedback via a position sensor.

　　Common Rail System: The common rail fuel system and servo common rail fuel system are supplied by high-pressure fuel pumps and servo fuel pumps respectively. Pressure varies with load. The system integrates a heat tracing pipe, safety valves (e.g., an overpressure valve that opens at 1050 bar), and leakage recovery lines.

　　Maintenance and Troubleshooting

　　Fault Diagnosis: Parameters (e.g., common rail pressure, injection timing, exhaust valve position) are monitored via the flexView HMI to identify alarm codes (e.g., 2223B001300 C3/C5 fault, WECS communication failure). For example, an 2223B001300 C3/C5 module power failure or crankshaft sensor malfunction may trigger system deceleration or shutdown.

　　Emergency Handling:

　　Module Replacement: Faulty modules can be quickly replaced with online spare parts, following the principle of "single-cylinder modules cannot be replaced simultaneously" (e.g., cyl.1/2, 3/4, 5/6 must be operated in groups) to avoid system instability.

　　System Validation: Factory testing verifies the function of the fuel injection valve and exhaust valve, simulates a crankshaft sensor failure, and verifies the effectiveness of the emergency stop device to ensure compliance with IMO technical specifications.

　　Advantages and Benefits

　　Economy: Reduces operating costs by optimizing fuel consumption and decreasing mechanical load; intelligently balances cylinder load to extend engine life.

　　Environmental Benefits: Reduces NOx emissions, meeting international environmental standards such as Tier II.

　　Reliability: Modular design, redundant power supplies, and online maintenance capabilities improve system availability and reduce downtime.

　　Operation and Maintenance Points:

　　Installation and Debugging: When replacing a module, power must be disconnected first. Insert the module into the E90 box to trigger software download and observe the SW LED status until it remains constantly lit. After reinstalling it back into the original cylinder, the main unit must be restarted to verify version consistency.

　　Troubleshooting: Common problems such as "software version mismatch" alarms can be resolved synchronously through the E90 box. In emergencies, the power supply to a single-cylinder module can be disconnected to trigger the safety system to reduce speed or stop the engine.

　　Preventive Maintenance: Regularly check the module communication status (e.g., CAN bus signal), software version, and parameter settings to avoid compatibility issues caused by outdated versions.

　　Extended Functionality and Ecosystem

　　System Integration: Deeply integrated with the WECS-9520 control system, supporting additional functions of the MAPEX series (such as combustion reliability detection and torque vibration analysis), enhancing the main engine's health monitoring capabilities.

　　Compatibility: The module supports linkage with the main engine remote control system and safety protection systems (such as emergency stop valves) to ensure coordinated operation of the entire system.

　　Emergency Operation: In case of failure, prioritize replacing the spare module (which must first be installed in the E90 enclosure for data synchronization) to avoid on-site operation (still requiring reliance on the RT-flex control system). For example, if cylinder 1 2223B001300 C3/C5 fails, the main engine will reduce speed but not stop, while the remaining cylinders continue to run; after replacement, crankshaft rotation, alarm reset, and test run verification are required.

　　Daily Maintenance: Regularly check power lines, module interfaces, and sensors (such as crankshaft angle sensors) to avoid mechanical damage; the software version must be compatible with the main engine to prevent compatibility issues; in low-temperature environments, heat tracing pipes are required to prevent the common rail system from freezing.

　　In summary, the 2223B001300 C3/C5, as the "intelligent cylinder brain" of the Wärtsilä RT-flex diesel engine, achieves a balance between fuel economy, emission compliance, and operational reliability through precise electronic control technology and modular design, serving as a key support for the intelligentization of modern marine power systems. Its automatic software synchronization, self-diagnosis of faults, and flexible control strategies significantly improve main engine maintenance efficiency and operational stability.
