SkyPup, sounds like a little explanation is needed here.

It has been a long time sence chem class but I will give the basics as I understand them.
The important parts of dino fuel is hydro-carbon (H-C). During combustion 2H combine with one O (from air) to make water, a C combines with 2O to make CO2. A undisrable effect is NOx. In a rich burn (more fuel than air), there is not enough O to complete all the CO2 combinations. In a lean burn (more are than fuel), there is plenty of O to complete all the CO2 combanations. There is so much O that NOx is made.

Why gasoline/spark ignition motors make carbonmonoxide (CO). The air fuel mixture goes in the cylinder at 14 or 15 to 1 ratio (air to fuel). It is rich.

Why diesels motors make nearly no CO. The air fuel ratio is 20, 30, 40 or 50 to 1 depending on the load. It is lean.

If your diesel is makin CO, you have problems.
