While some other, liquid cooled engines do not use any water but special fluids with enhanced properties like ethylene glycol. On the contrary, air cooled engines use air but no water or other chemicals to cool themselves. Liquid cooled and air-cooled engines are interdependent as most liquid cooled engines use some amount of air to cool over heating and air-cooled engines use liquids for cooling down.
Basic Advantages & Features:
- A motorbike with liquid cooled engines is smoother and more resistant to breakdown than air-cooled.
- A liquid cooled engine produces more power/torque than an air-cooled one.
- A liquid cooled engine, since cooled by liquids, maintains a better control temperature.
- Air-cooled engines are fuel efficient, affordable and require lesser engine space than that of liquid cooled engines.
- The Maintenance costs of liquid cooled ones are higher than air-cooled engines.
- Liquid cooled ones are easy to operate (better riding experience) but certainty of liquid spilling out is high.
- Air-cooled engines are nosier and somewhat harsh than liquid cooled engines.
