PISTONS
Thermal barrier coatings applied to piston crowns have become popular in an effort to retain more of the
combustion energy in producing power,rather than being lost through absorption through the piston.
HPC1 and HPC2 are designed to reduce the transference of the heat.Heat is energy and energy is power ,
so it follows that keeping heat in the combustion space has the potential for an enhancement in power.
If heat is not as rapidly lost, then greater force is exerted against the piston for a longer period of time during the power stroke,creating more power.
The coating can also allow heat at the surface to move more evenly over the surface,reducing hot spots. These hot spots can lead to detonation as fuel is elevated to a temerature where it self ignites, before the combustion by the spark plug is initiated.
By retaining minimal heat on the surface of the piston crown, less heat is transfered to the incoming fuel mixture. When heat is transferred to thr fuel mixture ,it begins to expand.The negative effect of that is lesser volume of the fuel mixture is drawn into the combustion chamber. Coated surface also has the ability to reflect heat into the chamber for more even distribution of heat.This allows more of the fuel molecules to be oxidized, which in turn, means less fuel is needed for optimum power.

By applying a Dry Film Lubricant, friction, galling and wear are reduced. The lubricants are capable of carrying
loads beyond the crush point of the Piston. In addition, the lubricants are äfluid retainingö materials that actually hold
oil to the surface beyond the pressure where the oil would normally be squeezed off. The ability to carry greater loads,
up to 350,000 PSI, while increasing lubricity (reduced friction) allows tighter piston to wall clearances to be run.
This leads to better sealing with no increase in friction.
