What makes piston ring selection and ring endgap so important to engine life and power? What's more, what makes that first engine firing so critical to proper break-in and longevity? Those first few ...

But when done right, piston rings can create a power advantage by maximizing dynamic engine compression while still maintaining good oil control. This involves both proper selection for the intended ...

If for some reason you disassembled a Toyota engine just to put it back and hope it will still work, here’s a short tutorial on how to check the piston rings gap tolerance, which will tell you if the ...

If you’re like many of us, you don’t spend a lot of time thinking about the pistons in your engine. Most of the time you don’t need to, but there are times when burnt, scuffed, or cracked pistons need ...

No matter how much we love them, our engines are still basically inefficient air pumps and need all the help they can get to make power. Like any other type of pump, if it leaks, it won't work. And ...

Presumably that you want to replace the worn out piston rings of a Toyota VVTi engine, you’ll need to know how to correctly put the new ones in place. The hardest part is to reach the piston rings ...

In order to understand the relationship between the location of piston ring gap and instantaneous change of oil consumption during engine operation, the ring rotation and instantaneous oil consumption ...

In internal combustion engine, it is well-known that oil infiltrates the combustion chamber through the clearance between the piston ring and the cylinder bore with vertical reciprocating motion of ...
