We got the 4000 HP compressor running this week, but cannot load it until October due to the warm weather, so I will have to go back.
The combustion specialists made it up from Houston, and I like to pick their brain. The main purpose of this project is CO and NOx reduction, a side effect is 3-5% fuel savings due to the computer controlled injection. The cam was originally ground for a Miller cycle, it is now reground for a hybrid Otto and Miller and the turbo has been re-wheeled to obtain more boost.

Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
