Are you curious about alternative engine options? Do you want to know more about the Wankel engine and how to properly maintain it? Look no further, because in this article we will be delving into common issues and maintenance practices for Wankel engines. The Wankel engine, also known as the rotary engine, is a unique type of internal combustion engine that uses a rotary design instead of the traditional reciprocating piston design. This design offers several advantages, such as higher power output and smoother operation. However, like any other engine, Wankel engines also have their own set of common issues and require proper maintenance to ensure optimal performance. Whether you are a car enthusiast or a mechanic looking to expand your knowledge, this article will provide valuable insights on understanding common issues and maintenance practices for Wankel engines. So, let's dive in and explore the world of Wankel engines together!The Wankel engine, also known as the rotary engine, has been gaining popularity in recent years due to its unique design and high performance.

However, like any other engine, it is prone to certain issues that require proper maintenance to keep it running smoothly. In this section, we will cover the main issues that Wankel engines face and the best maintenance practices to keep them in top condition. Firstly, we will discuss the most common issue - apex seal failure. Due to the high rotational speed of the rotor, apex seals can wear out quickly if not properly maintained. To prevent this issue, regular oil changes and using high-quality oil are essential.

Additionally, keeping the engine well lubricated and avoiding excessive revving can also prolong the lifespan of apex seals. Another common issue with Wankel engines is overheating. This can be caused by a variety of factors such as a faulty cooling system or low coolant levels. It is important to regularly check the coolant levels and ensure that the cooling system is functioning properly to prevent overheating. Other issues that may arise include carbon buildup in the combustion chamber, which can be prevented by using premium gasoline and performing regular engine flushes. When it comes to maintenance practices, there are a few key things to keep in mind.

Regularly checking and changing the engine oil, air filter, and spark plugs are crucial for keeping the engine running smoothly. It is also important to follow the manufacturer's recommended maintenance schedule and address any issues immediately to avoid further damage. It is worth noting that Wankel engines require a bit more maintenance compared to traditional piston engines. This is due to their unique design and higher revving capabilities. However, with proper maintenance, they can last just as long as any other engine.

Now that you have a better understanding of the common issues and maintenance practices for Wankel engines, let's move on to some tips for keeping your engine in top shape.

Performance Upgrades

For those looking to enhance the performance of their Wankel engine, there are various aftermarket upgrades available such as high-performance apex seals and fuel injectors. These upgrades can improve the overall power and efficiency of the engine, providing a better driving experience for owners.

Regular Maintenance is Key

Regular maintenance is crucial to keep your Wankel engine running smoothly. By following a proper maintenance routine, you can prevent common issues and extend the life of your engine. Here are some key things to keep in mind:
  • Regularly check and change the oil: Just like any other engine, the oil in a Wankel engine needs to be checked and changed regularly. This ensures that the engine is properly lubricated and reduces the risk of damage.
  • Clean or replace air filters: The air filters in a Wankel engine can get clogged with debris over time, leading to decreased performance and potential engine damage.

    It is important to clean or replace these filters regularly.

  • Inspect and replace spark plugs: Spark plugs play a crucial role in the ignition process of a Wankel engine. It is recommended to inspect and replace them every 10,000 miles or as per the manufacturer's instructions.
  • Keep an eye on coolant levels: Wankel engines are known to run hot, so it is important to regularly check and top up the coolant levels. Low coolant levels can cause overheating and potential engine damage.

Addressing Issues Immediately

Addressing Issues ImmediatelyAs with any engine, it is important to address any issues immediately to prevent further damage and costly repairs. This is especially true for Wankel engines, which have unique characteristics that require prompt attention when problems arise.

Failure to address issues in a timely manner can lead to more extensive damage and more expensive repairs, ultimately resulting in a significant financial burden for engine owners. One of the most common issues that Wankel engines face is poor compression, which can significantly impact the performance and efficiency of the engine. This can be caused by a variety of factors such as worn apex seals, damaged rotor housings, or faulty spark plugs. It is important to address this issue as soon as it arises, as it can quickly escalate and lead to severe engine damage. Another issue that Wankel engines are prone to is overheating. This can be caused by a variety of factors such as a malfunctioning cooling system, low coolant levels, or a clogged radiator.

If left unaddressed, overheating can cause serious damage to the engine and result in costly repairs. In addition to these common issues, Wankel engines also require regular maintenance to ensure optimal performance and longevity. This includes regular oil changes, spark plug replacements, and inspections of the apex seals and rotor housings. By addressing these maintenance tasks on a timely basis, engine owners can prevent potential issues from arising and keep their Wankel engines running smoothly.


In conclusion, addressing issues immediately is crucial when it comes to maintaining Wankel engines. Failure to do so can result in costly repairs and potentially even the need for a full engine replacement.

By staying proactive and addressing issues as soon as they arise, engine owners can ensure the longevity and performance of their Wankel engines. So, whether you are a car enthusiast or a Wankel engine owner, make sure to keep a close eye on your engine and address any issues promptly to avoid any major problems in the future. In conclusion, Wankel engines are a great alternative engine option for those looking for high performance. However, like any other engine, they require proper maintenance to prevent common issues and ensure longevity. By following the tips and practices outlined in this article, you can keep your Wankel engine running smoothly for years to come.
