Lake Speed Jr. of Total Seal explains typical 3-ring piston setup and the function of each individual ring. In relation to modern Porsche engines using an air / oil separator, crankcase vacuum is also discussed as one of the methods of reducing piston ring tension. This and the following topics are covered:
What types of piston rings are there?
What does the top ring do?
What does the 2nd ring do?
What is a 3-piece oil control and how does it function?
How do piston rings work?
How does reducing ring tension increase horsepower and how is this accomplished?
What is an air oil separator and how does it help piston ring sealing?
How do you test your AOS (air oil separator)?
As a manufacturer of pistons and cylinders for both aircooled and watercooled Porsche engines, LN Engineering supplies Nikasil compatible piston rings with all its billet aluminum Nickies cylinders including custom ringsets from Total Seal featuring gas ported top rings as well as gapless top and second piston rings. Total Seal also offers specialized coatings like titanium nitride (TiN) which further improve the performance of piston rings in applications with Nikasil bores like those common to many Porsche engines.
