LECM – E6
A modular, engine-mounted control platform for gas, diesel and dual-fuel reciprocating engines, available in stand-alone, 2-stack and 3-stack configurations.
Description
Product overview
One engine-mounted platform, configured around the application.
The Woodward Large Engine Control Module (LECM) provides a modular, single-box control architecture for large gas, diesel and dual-fuel reciprocating engines. Stand-alone, 2-stack and 3-stack configurations allow the control platform to be matched to power-generation, marine-propulsion and industrial-engine duties.
Depending on the selected module combination, LECM can coordinate speed and load, air-fuel ratio, ignition or injection, knock and misfire monitoring, air, gas and exhaust flow, start-stop sequencing, protection, onboard data logging and communications. Each module has its own processor and application software while sharing information across the assembled system.
TURNER ECS can assess the engine, operating modes, field interfaces and validation requirements before defining the correct hardware and application scope.
Modular architecture
Build the control around the required engine functions.
The platform is available as individual MAIN, Electronic Ignition/Injection Driver (EID) and Auxiliary (AUX) modules, or as integrated MAIN + EID, MAIN + AUX and MAIN + EID + AUX stacks.
| Module | Primary role | I/O scope | Communications |
|---|---|---|---|
| MAIN | Core engine I/O and control functions | Digital, analogue, temperature, oxygen and speed-sensor inputs with digital, pulse-width modulation and analogue outputs | 3 CAN, RS-485, RS-232 and Ethernet |
| EID | Electronic ignition or injection drive | Speed-sensor and digital inputs with 20 ignition or injection drivers and a high-side digital output | 2 CAN |
| AUX | Extended knock, pressure and temperature monitoring | 24 configurable knock, pressure or thermocouple inputs plus speed inputs, high-side digital outputs and analogue outputs | 1 CAN |
