Operating with a lean-air fuel ratio promotes fuel efficiency, while lower exhaust temperatures contribute to longer component life.

A compact engine configuration provides more room inside the enclosure, making components easier to access for service.

The CG18 engine meets non-emergency emissions requirements without aftertreatment, eliminating related maintenance and replacement costs.

Approximately 90% of the CG18 engine hardware is shared with the proven C18 diesel platform for long-term durability.

The natural gas inlet with low pressure capability adds flexibility when integrating the generator set.
