In an engine, the relationship between the valves and the pistons is a precarious one. If there is too little space, they can collide. If this happens, the resulting carnage require replacing one of ...

Blueprinting has become an abused term. For those who build their own engines—or at least want to know how to check clearances like valve-to-piston on an existing engine—we will offer some techniques ...

It is desired to minimize clearance between the piston and the cylinder to reduce noise and suppress vibration. Although significant effort has been made for this purpose, increased piston friction ...

A UK automotive consultancy is using miniature, eddy current displacement sensors built into pistons on gasoline engines, to measure the displacement between the piston and the cylinder bore in real ...

Since wedge-style combustion chambers rely on the squish or quench area to create turbulence in the combustion chamber, an intriguing effect occurs in the combustion process. To better understand this ...

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 ...

ABSTRACT A new piston secondary motion analysis has been developed that accurately predicts piston strength and the slap noise that occurs when the engine is running. For this secondary motion ...

In an engine, the relationship between the valves and the pistons is a precarious one. If there is too little space, they can collide. If this happens, the resulting carnage require replacing one of ...
