Cummins dealerships have a product called 4C cleaner( combustion chamber cleaner) that they use mostly on generator engines. Stuff works quite good on removing carbon buildup inside engines and throttle bodies( I used to work for Cummins Northeast). Two cans for a 4cyl engine in the same intake port. Directions on can are very easy to follow, and you WILL want to do it in an open area. Won't smoke in a clean engine( tested it myself in a freshly rebuilt generator engine). Could be safe for diesel engines, not 100% sure.

It is always very amusing how our imagination is put to the test when overcoming reality. Redyaris
