TopicStirling engine.

B.E. 6th Mechanical

The Stirling engine was invented and patented by Robert Stirling in 1816.

The stirling engine is a reciprocating external combustion engine because fuel burns outside the engine itself and continuously.

The stirling engine is designed so that the working gas is generally compressed in the colder portion of the cylinder and expanded in the hotter portion resulting in a net coversion of heat into work.

What is stirling engine ….?

1. Two piston type or alpha stirling engine.2. Piston displacer type or beta stirling

engine.3. Gamma Stirling engine.

Types of gases are used….Air ,

hydrogen , helium ,

nitrogen or vapor.

Types of Stirling Engine.

Alpha stirling engine.

Beta Stirling Engine.

Gamma stirling Engine.

Operate using any available heat source.Simple design of an engine compare to other

reciprocating engine.It can be operate at lower pressure and provides

perfect balancing.

Disadvantages:It’s cooling system requires large amount of water.Not self starting.It has low power to weight ratio.Difficult to vary the power output.

Advantages:
