The rotary engine is an innovative design that has been popular since its introduction in the 1960s. It offers advantages in terms of power and fuel efficiency, but it is also prone to failure if not maintained properly. This article will explore what kills a rotary engine, the common causes of failure, and the preventive measures that can be taken to ensure its longevity. We will also take a look at the history of the rotary engine and how it has evolved over the years.
The Fundamentals of a Rotary Engine
Despite the many benefits of a rotary engine, there are a few factors that can contribute to its premature failure. In this section, we will explore the common causes of rotary engine failure.
Overview of the Design
An overview of the design of a rotary engine is key to understanding what can ultimately kill it. A rotary engine is a type of internal combustion engine that uses a rotary design rather than the more common reciprocating piston design. In a rotary engine, the crankshaft remains stationary and the entire cylinder block rotates around it. This design allows for a smoother, more efficient operation while offering increased power-to-weight ratios.
However, because of its unique design, the rotary engine is prone to certain issues that can ultimately kill it. These issues include oil starvation, fuel dilution, and thermal shock, all of which can be caused by improper maintenance or incorrect operation. To prevent these issues, it is important to have a thorough understanding of the rotary engine design and the associated maintenance requirements.
Oil starvation occurs when the engine is not sufficiently supplied with oil, which can lead to excessive wear and tear on the engine’s components. This can be caused by low oil levels, an incorrect oil viscosity, or inadequate oil flow. To prevent this issue, regular oil changes are essential, and oil levels should be checked regularly.
Fuel dilution is a common problem that occurs when fuel is allowed to mix with the engine’s oil, resulting in a decrease in lubrication and performance. This can be caused by over-fuelling or by using fuels that are not specifically designed for a rotary engine. To prevent fuel dilution, it is important to use the correct fuel and to have the fuel system regularly serviced.
Thermal shock is another issue that can kill a rotary engine. This occurs when the engine runs too hot or too cold for an extended period of time, resulting in excessive wear and tear on the engine’s components. To prevent this, it is important to ensure that the engine is running at the correct temperature and that the cooling system is regularly serviced.
By understanding the rotary engine design and the associated maintenance requirements, it is possible to ensure that the engine remains healthy and reliable for many years to come.
The Benefits of a Rotary Engine
When it comes to the benefits of a rotary engine, there are several to consider. The rotary engine is highly efficient, with a better power-to-weight ratio than traditional piston engines. It is also lightweight, compact, and can produce more power than a similarly sized piston engine. This makes it an ideal choice for applications where weight and size are a concern. Additionally, due to its unique design, a rotary engine does not require valves, camshafts, or pistons, meaning fewer moving parts and less maintenance. As a result, it can be used in a variety of applications, such as aircraft, motorcycles, and cars.
Despite its advantages, the rotary engine is not without its drawbacks. The main issue is that it is prone to oil starvation, which can cause catastrophic engine failure. This is because the rotary engine uses an oil pump to circulate oil within the engine and the oil is not recycled, meaning that it must be continuously replenished. Additionally, the design of the engine means that it runs hotter than a traditional piston engine and is more difficult to cool, resulting in higher wear and tear.
Ultimately, the benefits of the rotary engine outweigh the drawbacks. It is a highly efficient, lightweight, and powerful engine that can be used in a variety of applications. However, it is important to remember that it requires frequent oil changes and proper maintenance to prevent catastrophic engine failure.
Common Causes of Rotary Engine Failure
To better understand what can cause rotary engine failure, let’s take a closer look at the three most common causes: poor maintenance, overheating, and poor lubrication.
Poor Maintenance
Poor maintenance is one of the most common causes of rotary engine failure. Without regular maintenance, oil can become contaminated with dirt and debris, leading to decreased lubrication and increased wear on the engine components. Additionally, worn or faulty seals and gaskets can cause oil leaks, leading to a lack of lubrication and excessive heat build-up which can cause engine damage.
To ensure your rotary engine remains in peak condition, it is important to keep up with regular maintenance, such as changing the oil and filter, checking the cooling system, and inspecting the seals and gaskets for any signs of wear or damage.

Overheating
When it comes to rotary engine failure, one of the most common causes is overheating. High temperatures can lead to a number of issues, including warping of the engine block and head, cracking of the seals and gaskets, and burning of the oil. The higher the temperatures, the more susceptible the engine is to these issues, which can reduce the lifespan of the engine and lead to costly repairs.
One of the main causes of overheating is a malfunctioning cooling system. If the radiator is blocked, or if the water pump fails, the coolant won’t be able to circulate properly, resulting in higher temperatures. If the fan is not operating properly, it won’t be able to effectively cool the engine. Additionally, if the thermostat fails, the engine won’t be able to regulate its temperature, leading to overheating.
Another potential cause of overheating is poor lubrication. If the oil is too thick or has broken down, it won’t be able to lubricate the engine properly. This will cause friction and heat, which can lead to higher temperatures. Additionally, if the oil filter is clogged, the oil won’t be able to reach all the parts of the engine, leading to even higher temperatures.
Finally, if the engine is running too hot, it can lead to a buildup of carbon deposits. These deposits will cause a decrease in engine efficiency and an increase in temperature, setting off an ongoing cycle that can eventually lead to engine failure.
Overall, it is important to ensure that your rotary engine is properly maintained and lubricated, and that the cooling system is functioning properly. If these components are not working properly, it can lead to overheating and, ultimately, engine failure.
Poor Lubrication
Poor lubrication is one of the primary causes of rotary engine failure. When the engine’s rotors and seals don’t have adequate lubrication, it can cause significant wear and tear on the components, leading to decreased performance, increased noise, and ultimately, catastrophic engine failure. To prevent this from happening, it’s essential to ensure that your rotary engine is receiving the proper amount of lubrication and that the oil is changed regularly. Additionally, it’s important to use the correct oil for your engine to ensure that it’s properly lubricated.
