Regular readers will recall the photos we’ve run in the past from the Dresser-Rand Heritage Files. Contributors Mac and Betty Sine secured permission to have photos culled from the files occassion-ally reprinted in Gas Engine Magazine. This issue’s sampling shows Ingersoll-Rand Type XG integral engine-compressor site installations.
The Type XG was introduced in the mid-1920s and was first produced with a flat-type combustion chamber. Later, a Ricardo combustion chamber (named after British engineer Sir Harry Ricardo) was incorporated. The engines shown here appear to be of this type.
