The energy cells in early MM are the same as the 230 and 262 Allis diesels. Not many truly understand the purpose of these . They are not a precumbuston chamber, however these heads do use an air space under the intake valve. The energy cell is across from the inj. and takes a small amount of fuel each time the inj. fires. When the cyl. fires the pressure on the piston in standard cumbustion is around 650psi. at the same time the cyl. fires the fuel in the cell fires ind the pressure inside the hourglassed shaped cell goes up to around 1300psi and is metered back out into the cyl. into the air chamber giving 2 added things. First the disturbance in the burn patern causeing more complete cumbustion and increased fuel economy, second the metering of the high pressure continues to push on the piston head long after combution stops to give it exelent torqe. The down side of this system is by bleedind off part of the compretion during slow starts it makes it a little contrary to start when their cold. It does give it exelent torqe and very good fuel ratings. Hope this has'nt went on too long, and hope it helps. I forget the term but I think they called this the LANOVA design. Dave.
