That chamber in the piston is only one part of it. If you just spray in atomized fuel into that cup its no different. The multifuel process requires that and the specific spray patter and aim to accomplish the task. The simple chamber doesn't cut the mustard. These facts eliminate the maybe it's...

Doc, you are going to have to get a dyno, moving down road at 60 MPH is not empirical evidence.

Direct injection engines generally do not use a precup, indirect injection engines do! Precups are in the heads and not the pistons. It's hard to inject partially atomized fuel into a precup in the head. You can run any multifuel on gasoline without the FDC in place. You can't run the other...

Hate to break it to you but you are completely wrong! Attached is a piece written by David Doyle that kinda sums up the operation and design of the "Multifuel" engine. I would suggest you invest a little research on the subject before stating incorrect information. Us people seem to be a...

2 clarifications. There are multifuel, 5 tonners. M54A2 etc etc. The 809 series are diesel only. As far as the function of a multifuel, this is not determined by the FDC, it's determined by the combustion cycle process. Having a bypassed FDC only means that the IP cannot change fuel rates...
