Counterweights are designed into the crankshaft to provide:

  1. engine longevity

  2. fuel efficiency

  3. engine balancing

  4. power increase

The correct answer is: engine balancing

Counterweights are designed into the crankshaft to provide engine balancing. The purpose of these counterweights is to balance the reciprocating mass of the pistons and rods, which helps reduce vibration and harmonics in the engine. This ultimately leads to smoother operation, reduced wear on engine components, and improved overall efficiency. Therefore, the correct answer is engine balancing.
