This engine has a transparent cylinder so that combustion can be observed. Two components of cylinder volume are important: (a) The "Displacement volume" is the volume displaced by the piston as it ...

In order to understand how delivering ever more power and mpg at the same time is possible, here's a refresher course on how a gasoline engine works. A gas engine is both fundamentally simplistic and ...

Pump-displacement volume is typically determined by gear size. The oil pumps below (left to right) represent two different displacements, as noted by the case size. For high-performance work, a steel ...

SINCE the power output of an engine is practically proportional to the weight of the charge, the object has been to increase the weight of the charge burned. The weight of charge inducted by an ...

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 ...
