Split Cycle Engine

A lot buzz about this lately. And I read where it can be configured to run on either RUG or diesel.

Quote:

The Split-Cycle design is a variation on both 2- and 4-stroke engines. One cylinder provides compression while the adjoining cylinder provides the power stroke. When I first saw this design my initial reaction was along the lines of “hmmm, this’ll never fly ’cause only half the cylinders are producing power”. But as I thought about it, I realized that a conventional 4-stroke engine only produces power 25% of the time anyway.

It has a lot more surface area for heat loss and friction. No doubt it will run, but it won't be any more efficient than a conventional poppet valve engine.
