Making sure your engine has proper compression is vital for its health. You can rely on one of two methods to test this, but ...

Internal combustion engines typically have low efficiency, with modern gasoline engines around 35% and diesel engines ...

At first glance, the concept of engine compression is simple enough:It's the ratio of the volume of the combustion chamber and bore when thepiston is at bottom dead center (BDC) versus when it is at ...

As you may know, an engine's compression ratio is directly linked to its combustion efficiency. All else being equal, higher-compression engines tend to make more power while offering better fuel ...
