GE’s Jenbacher Type 6 Gas Engines

The result of continuous enhancements and extensive experience, GE’s Jenbacher type 6 gas engines are an advanced and reliable addition to our product line. Serving the 1.5 to 4 MW power range, the 1,500-rpm engine speed results in a high power density and low installation costs. In addition, the type 6 pre-combustion chamber achieves maximum efficiency with low emissions. Proven design and optimized components enable a service life of 60,000 operating hours before the first major overhaul.

Features & Benefits

Offers highest efficiency in its power class.
High-tech components maximize reliability.
LEANOX® lean burn control ensures minimal emissions.
Modern engine concept increases service-friendliness.
High-power turbocharger allows optimal operation at higher air intake temperature and altitude.

Application
GE’s Jenbacher type 6 gas engines can be designed as generator sets, cogeneration systems, or a container. Depending on customer specifications, a variety of heat sources and gas types can be incorporated to increase overall efficiency levels and reduce industrial emissions.
Applicable heat sources include engine cooling water, oil, mixture gas, and exhaust gas
Customers can dispose of environmental pollutants from landfills, and agriculture, chemical, and mining sites, while using the gases for power generation simultaneously
Applicable gas types include: natural gas, flare gas, propane, biogas, landfill gas, sewage gas, coal mine gas and other special gases (e.g., steel gas, wood, and pyrolysis gases)
Regional Considerations

GE’s Jenbacher type 6 gas engines can be employed globally.
Design
Based on a pre-chamber ignition system, air/fuel mixture charging, and a four-valve cylinder head, the type 6 gas engines were designed to allow for continuous performance improvements over time.
The four-valve cylinder head, included in the centrally located purged pre-combustion chamber, minimizes charge-exchange losses, and offers highly efficient and stable combustion and optimal ignition conditions.
The ignition energy of the spark plug is amplified in the pre-combustion chamber, which enables the highest efficiency, lowest NOx emission values, and stable and reliable combustion.
The TecJet™ gas dosing valve offers a high degree of electronic control and accuracy, rapid response time and adjustment of air/gas ratio, and a large adjustable calorific value range.The camshaft is equipped with Miller valve timing, which enables high efficiency through optimized ignition timing, reduces maximum compression temperature, and increases the safety margin to knocking limits.
