The combustion chamber is simple to change, just untighten the cylinder head, take it off and you can swap it out. This makes it very easy to adjust the combustion ratio to different circuits and fuels that are used. Combustion chambers for unleaded fuel can also be provided.
During intensive tests, on the racetrack, the cylinder head showed a better temperature development as it did as on the VHM test bench.
A lower engine temperature followed. The explanation of this phenomenon is the use of a special aluminium alloy, which has a very good heat transference.
An other advantage of the material is its resistance to detonation. It is also possible to design your own combustion chamber, just take a blind combustion chamber and you can make any type that you want.
