Second-Order Balance System (CR-V)



What’s the Benefit?

The unique second-order balance system helps provide smoothness, which enhances passenger comfort and the car’s quality feel. 

 

The Feature:

This Honda design uses a pair of balance shafts to counteract vibrations inherent in large-displacement 4-cylinder engines. 

  • Located in the oil pan, the balance shafts rotate in opposite directions at twice the engine speed. 
  • Eccentric weights built into the shafts generate inertial forces that counteract vibrations created by the engine’s pistons and connecting rods. 
  • As a result, these engines are smoother at all rpm ranges, from idle to redline.
