Based on the proven design concepts of Jenbacher Type 3 and Type 6 engines, Type 4 gas engines are characterized by high power density and outstanding efficiency.

Enhanced control and monitoring provide easy maintenance capabilities, as well as excellent reliability and availability.

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.

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

We also provide a range of upgrades for the Jenbacher Type 4 gas engine.
