J920 Features
INNIO’s J920 FleXtra Jenbacher engine is designed for durability, simple installation, and maintainability. The GenSet consists of three modules, including a generator, engine, and a turbocharger module, providing a high quality, pre-fabricated, standardized generator-set module. Each module is factory-tested, then shipped separately and assembled onsite, offering reduced installation time. In addition, the modules have highly standardized interfaces that work well with balance of plant (BOP) systems, and ultimately simplify BOP installations and total plant erection time. To maximize plant availability, the J920 FleXtra is optimized for operation and maintainability in the following ways:
POWER UNIT
The J920 FleXtra power unit concept ensures low maintenance downtime as the complete power unit consisting of cylinder head, water jacket, cylinder liner, piston and con-rod can be exchanged with one assembly.
FAST LOAD AND FAST TRANSIENTS
With the Jenbacher J920, 10.4 MW of electric power can be provided from the start in 2 minutes. Newest model-based control technology ensures low engine-out emissions levels during the engine start and operation. Together with integrated after-treatment systems and controls overall NOx emissions are minimized over the full load range and even during fast transient operations.
DIVIDED CAMSHAFT
The J920 FleXtra is equipped with a segmented camshaft to support fast maintenance of individual segments through a service window at the top of the crankcase instead of disassembly of the whole camshaft.

Through our global service network, you’ll have dedicated personnel that help ensure predictable operating costs of the Jenbacher J920 and risk mitigation. Remote diagnostics provide you with online access to your plant and J920 FleXtra equipment, thereby minimizing downtime, increasing plant availability, and lowering expenses for corrective maintenance. All work on your J920 FleXtra gas engine system — including upgrade, repair, and overhaul — is performed at your plant, saving you time and updating your engine with the latest technology.
Balance of Plant (BOP)
The right auxiliary equipment is of critical importance in ensuring that a power solution is economically feasible and provides your business with reliability, availability, and efficiency. Click on the provided BOP options to learn more.
Reach out to our experts to select the configuration that fits your business’ needs.
Available BOP elements may vary, depending on the engine and application type.
2-stage technology
The 2-stage turbocharger design of the J920 Flextra allows for no deration at higher altitudes and higher cooling water temperatures-perfect for hot ambient conditions
Modular design for flexibility
Modular gas engine design allows for seamless installation with any multiple-engine configuration and offers flexible size options.
Superior total efficiency
Operating a Jenbacher J920 FleXtra at about 94% of total efficiency and 48.7% of electrical efficiency.
Scope of supply:
Scope of supply, dedicated for applications, which require power generation only.
If you are looking for simultaneous power and heat generation, please consider Combined Heat and Power Module (CHP Module) scope of supply.
Minimum scope of supply for Genset: engine, alternator, turbocharger and control panel.
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.
J920 gensets can be installed inside a powerhouse:
INNIO’s J920 FleXtra is specially adapted to large gas engine power plants. It offers a highly standardized powerhouse plant concept with fast delivery times and low installation costs. While the size of the plant, actual plant design, and layout depend on your specific customer needs and site requirements, the J920 FleXtra plant solution is developed as a modular system with a minimal footprint. This design allows for seamless installation with any multiple-engine configuration, and, therefore, offers flexible size options for a multiple 10 MW system at constant high electrical efficiency levels. Combining the multiple-engine concept with a 2-minutes engine start-up time provides flexible power – from baseload to cyclic and peak operations.
Combined Heat and Power Module (CHP Module) J920 FleXtra solutions allow customers to generate power and heat simultaneously at a very high total efficiencies, of about 94%.
The simple use of jacket water heat and heat from oil and charge air coolers, combined with heat from the gas engine exhaust makes CHP in combination with the J920 FleXtra gas engine a favorable solution. When the heating water circle is designed to include return water at 70°C and hot water at 90°C or more a high total efficiency is achieved. The 2-stage turbocharging technology has the ability to increase the total efficiency for providing power and heat up to the level of around 94%.
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.
