Conditions to work
Now we have seen what follows a Stirling engine cycle and how it occurs, but several conditions must be clear that, in a real situation, this works:
- The temperature difference determines the performance of the engine (as you've already seen the physics of Stirling), which means we get to keep the more extreme temperatures (both high and low) increased the chances that the and machine run more efficiently.
- It is very important to reduce the friction of the parts as possible. Since all types of Stirling engines require sealing, is a difficult thing to build an engine. The pieces should fit perfectly should slide smoothly. Friction is a force that opposes motion whenever we want, so it is important to avoid the best way to counter this point it will decrease performance.
- Perhaps the most important condition is to keep the engine working gas that makes up the system completely sealed inside the engine. Put another way, the engine must be completely airtight. If there is any leakage, it prevents the system to increase its pressure, so it is impossible to give and Stirling cycle.
- Keep in mind the dimensions of the motor. Although not a completely strict, it is important that in a beta or gamma Stirling type, the cylinder piston and the route of this work are lower than the reciprocating piston displacement. In an alpha type, it is necessary that the two cylinders have a similar size.
- The angle of rotation of the crankshaft between the elbows should be 90 degrees. Although there are people who invented motors with other angles, are models that do not consider themselves exceptional Stirling engines.
