Shape Charge
The sketch below is comparing a Chris-Cross style combustion
chamber compared to a 30-06 cartridge. Notice the similar angles,
and the ignition flame travel.

The sketch above helps to visualize how using a shape charge can work better
in a internal combustion engine. We are using this technology to harness a better
combustion cycle (a more complete burn) inside the bore of a internal combustion engine.
Better combustion gives more power/performance, lower emissions,
and better fuel economy. Remember, it has to achieve this cycle
50-100 times a second.........That's REAL FAST.
