When servicing refrigeration or air conditioning systems that incorporate reciprocating or piston-type compressors, worn compressor rings and/or leaky compressor suction or discharge valves can cause ...

Cam lift and timing can put the valves dangerously close to the piston. We show you how to check the clearance In all but most the mild engine builds, taking extra time to check piston to valve ...

You've probably read this line a dozen times: "It's never been easier to make horsepower than right now." While that's true, it also means everything else in the engine is now more highly stressed.

The capacity of a compressor is measured in Btu per hour (Btuh) or Btu per minute (Btu/min). Remember, there are 12,000 Btuh or 200 Btu/min in one ton of refrigeration. The capacity of a piston-type ...

Interference engines allow the piston to go further into the combustion chamber to increase compression, and the valves to go deeper so they open wider and for longer. Both pistons and valves move in ...
