Throughout this site we use many technical terms, and given the breadth of readership our site enjoys, sometimes we are remiss and incorrectly assume everyone knows what we are referring to. For those that do not, here are some explanations of the technical terms use.
Masked Inlet Valve
A poppet-type valve having the addition of a shroud or mask for part of the circumference under the valve head; to ensure correct location of this mask in the inlet port, the valve stem has a flat section to line up with the key in the valve guide. The object of this design is to direct the incoming gas into a rotation of the bore and so increase turbulence to enhance thorough combustion of the air/gas mixture.
