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.

The new Jenbacher* gas engine is based on the proven Type 4 platform of more than 4,000 installed engines generating about 4.5 GW of power worldwide. The innovative design and engineering excellence translate to as much as an up to 4% increase in output – to 1,560 kW – and about up to 1% point boost in electrical efficiency compared to the respective J420 B gas engine versions. The new J420 exemplifies compact design, serviceability, and standardization. While these units provide significant advantages for pure power generation – fueled with natural or biogas, they truly excel in cogeneration (CHP) applications and as hot country version. Additionally, they are remarkably well-suited for container installations.
