Jenbacher Type 6

The result of continuous enhancements and extensive experience, the Jenbacher Type 6 engines are an advanced and reliable addition to our product line.

The 1,500-rpm engine speed results in a high power density with low installation costs, and its pre-combustion chamber achieves high efficiency with low emissions.
~6,400 engines delivered since 1989 (J624 since 2007).

        Highlights of Jenbacher Type 6 engines

        Type 6 engines are loaded with features that enhance heat recovery, assure stable combustion, reduce emissions, and increase efficiency—taking the Jenbacher line to new levels of performance.

        • A centrally-located purged pre-combustion chamber helps provide optimal ignition conditions.
        • The spark plug ignition energy is amplified in the pre-combustion chamber, facilitating stable and reliable combustion.
        • Miller valve timing creates reduced compression temperature and an increased safety margin to knocking limits, providing improved ignition timing and high efficiency.

        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), 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.
