        Highlights of Jenbacher Type 4 engines

        Jenbacher Type 4 engines have the same design, emissions control, and waste gas-to-energy capabilities as their Type 2 and Type 3 counterparts, plus high power density and outstanding efficiency in their power range.

        • The high-power turbocharger allows optimal operation at higher air intake temperature and altitude.
        • A hour-valve cylinder heads features enhanced swirl and channel geometry using advanced calculation and simulation methods, resulting in optimal cooling and combustion conditions.
        • The Type 4’s connecting rod reduces bearing wear and is easy to maintain.

        Applicable gas types include: natural gas, associated petroleum gas (flare gas), propane, biogas, sewage gas, landfill gas, coal mine gas, other special gases (e.g. coke, wood, and pyrolysis gases).

        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.
