Greater reliability and serviceability
Compact and easy to Service
- This design modification improves the operating conditions for the ignition-rails and the knocking detection system and results in lower component temperature.
- Our optional steel pistons provide much higher power loading capability as well as significant reductions in total unburned hydrocarbons (THC), resulting in improved efficiency.
- Optimized piston cooling technology translates to better heat dissipation and thus reduced thermal load - increasing the overall robustness of the entire power unit.
- A longer component life and exchangeable cartridge further reduces service costs.
- Our innovative split-frame design simplifies installation in restricted spaces.
- The new installation concept reduces vibration levels, translating to less component stress.
- High-flexible coupling significantly reduces vibration transmission to the generator.
- 3D-adjustable chocks provide rigid generator support and fast alignment possibilities.
- Quickly removable safety guards offer improvement over a bell-housing design, meaning that the generator doesn’t need to be shifted for coupling changes.
- The new design delivers easier access to all maintenancerelevant parts like filters, pumps and turbocharger.
- The new hydraulic concept covers various customer requirements and enables standardized and proven interfaces. Consequently, flexibility regarding heat recovery concepts can be achieved without compromising reliability.
- Latest turbocharger technology delivers excellent efficiency in addition to full output at high ambient temperatures and altitudes.
- Derived from proven Type 6 engine technology, our new gas mixer design delivers a homogenous, stable and smooth gasto-air mixture-with a wide range of fuel gas types-over the entire power range to enable secure low NOx operation.
- The maintenance-friendly concept of the throttle valve actuator improves reliability, and the integrated flame arrestor also supports operational safety specifically for special gas applications.
- Three pre-defined interface panel positions help optimize adjustments to local conditions.
- A single cartridge with a larger filter surface delivers longer life.
- Electronic differential pressure monitoring improves service friendliness.
- Our newly designed cylinder head with an optimized camshaft profile improves the charging efficiency, which translates to greater fuel efficiency.
- An enhanced cooling design further reduces thermal load improving the component robustness and service life.
- New position TC & intercooler
Scope of supply:
Combined Heat and Power Module (CHP Module) solutions allow customers to generate power and heat simultaneously at a very high total efficiencies, reaching 90% and even more.
Usual scope of supply:
- Engine and alternator installed on the frame
- Control panel, gas train
- Heat exchangers including exhaust gas heat exchanger
CHP Modules can generate hot water or steam at various parameters and can be integrated with your existing heat infrastructure. You can select the option that fits your project’s needs among the various heat recovery schemes provided by Jenbacher.
The scope of supply can be extended further with various balance of plant options (BOP) offered by Jenbacher, reach out to our specialists for help in selecting scope of supply and BOP options to fulfill your project’s needs.
CHP Modules can be installed inside a building or inside a container. To see more details about Jenbacher’s Containerized solutions, click here.

Available BOP elements may vary depending on the engine and application type.
- Removes silicone and siloxane compounds from biogas and sewage gases
- Reduces deposits in the combustion chamber of the engine
- Ensures required gas quality for the installation of an oxidation catalyst in the exhaust system
Part of Jenbacher minimum scope of supply.
- Contains a 3 μm fine filter as a security filter
- Includes a pre-pressure regulator for improved reliable operation – reduces gas pressure variations caused by other gas users or the gas supply network
This exhaust gas after-treatment option is available for INNIO’s Jenbacher gas engines.
Oxidation catalyst (in own chamber) for the reduction of CO and HCHO (formaldehyde) emissions – for natural gas and biogas engines (fuel gas quality dependent).
Exhaust Gas Heat Exchanger allows your business to maximize utilization of useful heat from the engine.
Used along with Jenbacher CHP Modules. Can be installed inside the building or together with Container power plant solution.
- Available for all types of exhaust gases resulting from a wide range of fuel gases
- Material: Carbon steel, stainless steel, or specialized stainless steel depending on fuel types
- Optimized flow rates and exhaust gas back pressure for various applications
- Available with or without exhaust gas bypass
Combines robust real-time and model-based control for the genset with a highly customizable auxiliary management system to meet our customers individual requests in the best way possible.
Additional to our module control panel, Jenbacher also provides power plant control solutions through master synchronization and master control.
