The amazing thing about Stirling engines is that, unlike traditional internal combustion engines, they don't require any additional machinery to run. Therefore, they don't require carburetors, injectors, cams, valves, spark plugs, throttle bodies, timing chains, belts, etc., in short, any part you can think of. Additionally, they don't require coolant circulation to lower temperatures, and as you can see, they don't even require lubrication when operating. Their design is very simple.
Stirling engines are considered a promising energy alternative to conventional internal and external combustion engines. It works by burning any form of fuel to generate heat, which is then used in cylinders to provide power. This makes it very flexible and can use a variety of fuels such as liquid, solid or gaseous, and can even rely on clean energy sources such as nuclear and solar power.
The Stirling engine is known for its continuous and complete combustion process, which makes its emissions very clean and does not produce harmful exhaust gases. This is valuable for improving urban air quality and reducing pollution.
The Stirling engine is known for its simple yet elegant design, as it is very different from traditional internal combustion engines and the like.
The working principle is simple: The working principle of the Stirling engine is based on the expansion and compression of gas caused by temperature differences. It does not require spark plugs, fuel mixing or high-speed rotating parts, so the working principle is relatively simple.
Quiet Operation: Compared to internal combustion engines, the Stirling engine operates very quietly as it has no explosive explosion and exhaust noise. When you lift it up, it makes very little noise, but when you put it on a table, it makes the whole table vibrate.
High efficiency: Stirling engines can have relatively high thermal efficiencies, especially in low speed and low power applications, giving them a competitive advantage in certain areas.
Clean energy: We don’t consume any additional energy; we don’t add any new heat, which is why the Stirling engine is so environmentally friendly and efficient.
Reliability: Due to their mechanical simplicity, Stirling engines generally have a longer life than internal combustion engines because they have little friction and wear.
Versatility: Stirling engines can be used in a variety of applications such as power generation, heating, refrigeration, etc., making them versatile.
Although the Stirling engine is currently only used at the hobby level, as you can see it is capable of running for long periods of time using waste heat. It essentially exploits temperature differences within the system without requiring additional energy input. For example, when you turn off a stove or oven, a lot of waste heat is produced in it, enough to power a small Stirling engine and generate electricity in a minute or two or three. Likewise, when you park and turn off the engine, the waste heat in the exhaust pipe is enough to power the Stirling engine for about 5, 10, 15 or even 20 minutes, charging the hybrid car's battery without having to plug it in. Any power source .
However, as the focus on energy efficiency increases in the future, we are more likely to adopt innovative energy solutions. Some aviation authorities are already looking into whether Stirling engines could be a future alternative generator. expect.
