Jenbacher® Gas Engine Series
The Jenbacher® Type 2 Series

Durability & Track Record
Since 1976, theJenbacher® Type 2 engine has proven its reliability worldwide, thanks to its robust stationary-engine design and long overhaul intervals.
Fuel Flexibility
It operates on a wide range of gases, including natural gas, propane, biogas, landfill gas, sewage gas, coal mine gas, and other specialty gases, making it versatile for various applications.
High Efficiency & Performance
Offers excellent electrical and thermal output (250-360 kW), with high efficiency and enhanced combustion, even under demanding conditions.
Low Operating Costs & Easy Maintenance
Designed for long service life (up to ~80,000 operating hours before major overhaul), with components that reduce maintenance effort and cost.
The Jenbacher® Type 3 Series
Proven & Reliable
Over 220 million operating hours and 8,000+ engines delivered since 1988; high availability of up to 98%.
Fuel Flexibility
Runs on natural gas, flare gas, propane, biogas, sewage gas, landfill gas, coal mine gas, and other special gases.
Strong Efficiency & Performance
Power range from ~400-1,100 kW with long service intervals (up to ~80,000 hours before major overhaul).
Versatile & Adaptable
Designed for multiple installations: generator set, containerised units, or CHP (combined heat & power) setups; performs well in challenging conditions.
The Jenbacher® Type 4 Series
High Power Density with Fuel Flexibility
Type-4 combines proven technology from Type-3 and Type-6 models, offering excellent power per unit size, with the ability to run on many different gases (natural gas, biogas, sewage gas, landfill gas, etc.).
Outstanding Efficiency & Reliability
Designed for both 50 and 60 Hz operation, featuring advanced cooling, monitoring, and combustion control, yielding high electrical and overall efficiency, plus reliable performance and easy maintenance.
Durability & Easy Maintenance
Equipped with features like a high-power turbocharger, four-valve cylinder head, and “crack” connecting rod design to reduce wear, simplify repairs, and maintain performance even under harsh conditions.
Scalable & Versatile Applications
Power range from roughly ~850 to ~1,560 kW, suitable for generator sets, cogeneration (CHP), or containerised modules. Offers heat recovery options and compatibility in diverse installations.
The Jenbacher® Type 6 Series
High Power & Flexible Fuel Use
Delivers 2.0 to 4.5 MW electrical output, compatible with a variety of gases (natural, biogas, landfill, etc.), for versatile large-scale power needs.
Efficiency with Low Emissions
Features like a pre-combustion chamber, LEANOX lean-burn control, and enhanced pistons help reduce emissions while keeping fuel consumption low.
Strong Reliability & Long Service Life
Designed for harsh conditions, with a proven design, enhanced components, and a 60,000-hour interval before major overhaul.
High Efficiency & Power Density
Runs at 1,500 rpm for maximum power density, meaning more output in less space, reducing installation costs. Also optimized for heat recovery for combined heat & power (CHP) applications.
The Jenbacher® Type J624 Series
Leading-Edge Twin-Turbo Power
The world’s first 2-stage turbocharged gas engine, delivering ~4.4 MW electrical output at 1,500 rpm.
Exceptional Efficiency & Cost Savings
