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 ...

It is incomplete to even talk about degreeing a camshaft without discussing piston-to-valve clearance. It's like learning how to drive but never being taught how to use the brakes. Learning how to ...

The instance of piston striking valve is right up at the top of the list of things that will ruin your day. It's fundamental tothe four-stroke cycle that valves and pistons come close to one another, ...

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 ...

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 ...

The piston rings on any engine have three main purposes - to ensure the combustion chamber’s tightness, to clean the cylinder and to leave a very thin layer of oil on its surface in order to reduce ...
