What is the Benefit of an Oil-cooled Engine Over an Air-cooled Engine?

/ / , / 0 Comments

Engines come mainly in two types: air-cooled and oil-cooled. Air-cooled engines are relatively simpler and less expensive to maintain. However, they might be prone to easy overheating especially on high speed or exposure to hot weather. An oil-cooled engine, like the one on the Hero XPulse 200, is relatively more complex and expensive to maintain compared to the former, but it can run relatively cooler and more efficiently.

Which one is better, then? Well, that depends on your requirements and the type of riding you do. Casual riders doing short trips might get away with an air-cooled engine. Serious riders who often go long distances or ride in extremely hot weather would be far better off with an oil-cooled engine.

The Hero XPulse 200: A Case Study

Among the various bikes, the Hero XPulse 200 highlights the practicality of oil-cooled engines. It is an adventure bike built for off-road riding and capable of running under extreme temperature and conditions. The XPulse 200 comes with a 199.6cc, single-cylinder, oil-cooled engine, which produces 13.5 kW of power @ 8000 rpm and 17.1 Nm of torque @ 6500 rpm.

Benefits of an Oil-cooled Engine

Some advantages of an oil-cooled motorcycle engine like the Hero XPulse 200 are as follows:

  • Heat dissipation: One of the great advantages of an oil-cooled engine is the dissipation of heat. Oil absorbs and transfers heat significantly better than air does. This would mean that the temperature of the engine is kept lower, and that will, in turn, enhance performance as well as other aspects of reliability.
  • Better Performance: An oil-cooled engine also provides better performance. Since an increase in the compression ratio is easier with better cooling of the engine, more power and torque get delivered from it.
  • Longer Engine Life: Another factor is that the lower temperature also helps extend the engine life. This happens simply because there will be less wear on the components of the engine.
  • Low Noise: Oil-cooled engines are also quieter than air-cooled engines. This is because of the fact that oil helps to keep the noise created by the engine damped.
  • Fuel Economy: Sometimes, oil-cooled engines can also be more fuel-efficient compared to air-cooled engines. This happens because the engine can run on a leaner air-fuel mixture and, subsequently, will improve fuel economy.

Drawbacks of an Oil-cooled Engine

There are, however, some disadvantages of an oil-cooled engine as follows:

  • Increased Complexity: Oil-cooled engines are much more complex than air-cooled engines. Hence, they are much costlier to maintain and service.
  • Higher Weight: Oil-cooled engines are also more weighty compared to air-cooled engines. This is because it has to carry the weight of an oil cooler and oil.
  • More Costly: Bikes with oil-cooled engines are more expensive to purchase compared to air-cooled engines.

Final Thoughts

Overall, the benefits of an oil-cooled engine outweigh the drawbacks. If you are looking for a motorcycle that is reliable, powerful, and efficient, an oil-cooled engine is a good choice. That being said, the Hero XPulse 200 is a great adventure bike with an oil-cooled engine for enhanced performance, and the competitive XPulse 200 price makes it worth it.

So, take a test ride and feel the power of this bike.
