- Optimally tailored to the engine and made by renowned manufacturers, the generator ensures a high level of reliability with the best degree of efficiency.
- 3. Ignition system
- Ignition systems for individual cylinders allow for the most efficient level of operation for all cylinders, even with variable CH4 content. The ignition voltage display gives customers information about the state of the spark plugs.
- 4. Mixture cooler
- The two-stage mixture cooler with large surface area improves engine performance and heat utilization.
- 5. Knock detection
- Cylinder-specific knock detection and regulation protects the engine from abnormal operating conditions and guarantees safe operation even with natural gas with a low methane number.
- 6. Crank-case ventilation
- High quality crank-case ventilation minimizes deposits in intake tract and combustion chamber and guarantees a continuously high level of performance.
- 7. MTU Module Control (MMC)
- The MTU Module Control (MMC) contains all the important functions necessary for controlling the system. All the auxiliary drives required for the CHP system can be operated from here. The integrated power circuitry minimizes the need for cabling on site.
