I'm afraid I'm not an expert, and a real diesel mechanic should be consulted to verify what I'm going to say here. But as far as I know, all diesels are good to go with an HHO device without an EFIE. The reason is that they don't maintain fixed air/fuel ratios the way gas engines do. Diesels vary their air/fuel ratio dramatically in order to provide acceleration and deceleration. in theory, adding an HHO device would just increase your horsepower for any given throttle position. It should be as simple as that.
Gas engines try to maintain a 14.7:1 air/fuel ratio, and the HHO tricks the computer into making the mixture too rich. That's the only reason we use the EFIE: to un-trick the computer and get it back to 14.7:1. Diesels just don't have this whole thing going on, and therefore shouldn't require an EFIE.
If you find out anything different on this, please let me know. But this is my understanding of the situation.
Are you having trouble with mileage gains with a particular common rail diesel engine?
Ignore the previous post with nothing in it. I am new to this forum thing.
No problem...yet. We manufacture the MileageMaker and I have a dealer in Scandanavia working the Scandanavian big rig markets. I was relaying the question I received from him. Thanks for the assist.
