JENBACHER TYPE 4 

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.
