Piston Coating
|
Pistons are the highest stressed and the most
critical part of an internal combustion engine. This is especially true for a
two stroke motor. The four cycle piston only sees heat from combustion every
other stroke, and in between, it has a full stroke to be cooled by the fresh
incoming air. To further aid cooling, four stroke pistons are often cooled on
the underside by oil spray and runs in a cylinder with no ports to interrupt the
rings. The two stroke piston sees the heat of combustion on every stroke without the benefit of a cool intake stroke or oil spray. Also, the two stroke cylinder is full of ports that attract heat, especially on the exhaust side where the hot gases flow directly over the crown on their way out of the cylinder, building even more heat in the cylinder near the exhaust port. This extreme heat can burn the little lubrication that the piston skirts see. This is why the piston is the weak link in the two stroke motor.
HVCcycle applies our TPC ceramic coating to the
top of pistons, holding heat in the combustion chamber where that heat can be
used to power the motor, rather than dissipate through the piston where it can
weaken and burn the piston. This allows This Process can double the life of a 2-Stroke piston.
