What is clearance volume and swept volume?

Vishal Tiwari said: 7 years ago

Clearance Volume = Total Volume/Clearance volume.

Meet Jaiswal said: 7 years ago

Compression Ratio = (VC+VS)/VC.

Hence increasing VC will decrease CR.

Akash said: 10 years ago

Because if volume increases the pressure will be lesser and hence compression effect is reduces.
