INTERESTING..Why Stirling Engines Are Not Used

February 14, 2022

Answer 1 of 6. The nature of the engine is such that in practice it will probably lose a great deal of energy with heat loss heat transfer etc.

If a Stirling engine uses helium or for the more insane hydrogen it can reach those levels.

Why stirling engines are not used. Because of this Stirling engines are very quiet. If this is the case then why is Stirling engine not used is this due to lack of research since steam turbines became popular. Could they generate our electricity in the future.

Stirling engines do have as high if not higher theoretical efficiency than steam turbines note the word theoretical. Stirling engines are not good for applications that need to change their power output levels quickly like cars for example. This will also increase the power density of the engine.

Why Stirling engines are not used. But then some articles said that upon using helium in the Stirling engine the size will become much smaller. Theyre better at a constant speed so if you need to accelerate quickly when the light turns green Stirling engines are not the engine for you.

No combustion takes place inside the cylinders of the engine. Most of the engines require maintenance because of the inner atmosphere the gas used for transfer. Helium is expensive and rare.

Why Stirling engines are not used. The Stirling cycle uses an external heat source which could be anything from gasoline to solar energy to the heat produced by decaying plants. Plus they tend to be heavier and more expensive than gasoline or diesel engines of a similar power output.

Why Stirling engine not used as primary source to operate generator in. Sterling Engines are too expensive now. Why are Stirling engines not used.

Stirling engines are not good for applications that need to change their power output levels quickly like cars for example. Plus they tend to be heavier and more expensive than gasoline or diesel engines of a similar power output. The engine requires some time to warm up before it can produce useful power and the engine can not change its power output quickly.

Stirling engines are not good for applications that need to change their power output levels quickly like cars for example. Stirling Engines Like to Run at a Constant Speed. They simply need a difference in temperature between the heat source where the energy comes from and the heat sink where it ends up.

Heres the Short Answer. The concept of using the sun to build up pressure and turn something with enough mechanical work to turn a motor seems pretty simple. Moreover there is no established production and use of Stirling engines in large numbers and little prospect of the massive capital and operating funds necessary to accomplish this.

Although described as external combustion engines Stirling engines dont have to use combustion actual burning of fuel at all. Answered 3 years ago Author has 3K answers and 72M answer views. It works in F1 and in the trucks and would work in hybrid cars with a small internal combustion engine.

See the follow-up. Modern compound engines use electric motors to translate the speed of the turbine to the speed of the wheel or propeller. Can you pump lava into Stirling engines.

Stirling engines are not great for uses in cars and other applications where you want to regulate the output on demand. Great strides could be made in solving this dilemma by using elaborate control systems regulating pressure etc. Stirling engines are having a bit of a revival.

Technically all youd need is land a system of mirrors which aimed the sun at a central location to be heated up and some sterling engines to make solar power. The cooling system must have twice the capacity of that required for a diesel engine of equivalent power. More dangerous More dangerous.

I understand why solar-powered stirling engines are not used in the power station size but why arent solar-powered turbines used in homes. Stirling engines due to their natur. Stirling engines do not respond as quickly to changes in power requirements as an ICE and take longer to warm up before reaching full power.

This will also increase the power density of the engine. For this reason the Stirling engine is not suitable for applications that require fast starts or rapid changes in speed. There are hundreds of ways to put together a Stirling engine.

For this modern electronics is needed. Stirling engines are not right for anyone who wants to go from 0 to 60 quickly. Heres the Short Answer.

Stirling engines are not good for applications that need to change their power output levels quickly like cars for example. I think the method that is used now is steam engines. If this is the case then why is Stirling engine not used is this due to lack of research since steam turbines became popular.

The inherent thermal inertia of an external combustion engine makes it slower to start. Automotive Stirling Engine. Plus they tend to be heavier and more expensive than gasoline or diesel engines of a similar power output.

However Stirling engines are generally not price-competitive as an automobile engine due to high cost per unit power low power density and high material costs So even though they are more efficient a Stirlings initial outlay and space impacts mean they are unlikely to replace diesel prime movers etc in industry unless they are used as part of a CHP system. What are they and how do they work. Stirling engines like to change their power output levels slowly.

Yet solar panels are getting so cheap now that theyre hard to beat with other methods. Heres the Short Answer. Plus they tend to be heavier and more expensive than gasoline or diesel engines of a similar power output.

But then some articles said that upon using helium in the Stirling engine the size will become much smaller.
