Radial Engine is a reciprocating type Internal Combustion engine in which the cylinders point outwards from a central crankshaft like the spokes on a wheel. This type of engine was commonly used in most of the aircrafts before they started using turbine engines.

4. PARTS OF A RADIAL ENGINE
1. Piston
Material: Aluminum Alloy 4032-T6
A piston is a moving component that is
contained by a cylinder and is made gas-
tight by piston rings.
Its purpose is to transfer force from
expanding gas in the cylinder to the
crankshaft via a piston rod and a
connecting rod.

5. 2. Articulated Rod
Material: Aluminum Alloy 7075
The articulated rods are the connecting
rods between the master rod and the
other pistons of the radial engine.
3. Master Rod
Material: Aluminum Alloy 7075
When the engine is working, the master
rod or piston rod is under gas forces and
inertia forces.

6. 4. Rod Bush (Lower, Upper)
Material: Aluminum Alloy 7075
Rod Bushes are used for reducing
vibrations in the engine which provides
cushioning effect to it.
5. Piston Pin
Material: Alloy Carburized Steel
Piston pin (Gudgeon pin) connects the
piston to the articulated rod and
provides a bearing for the rod to the
pivot upon as the piston moves.

7. 6. Piston Ring
Material: Gray Cast Iron
Piston rings seal the cylinder so that
combustion gas does not leak into the
opening between the piston and the
cylinder.
7. Piston Pin Ring
Material: Alloy Carburized Steel
Piston plugs ensures that the piston is
centered within the cylinder barrel.

8. 8. Master Rod Bearing
Material: Aluminum Alloy 7075
The crankpin end of the master rod
contains the master rod bearing that is
used to hold spinning shafts where
support is required to keep the rod
straight.
9. Link Pin
Material: Aluminum Alloy 7075
Link pins are used to connect the master
rod to the articulated rod of the radial
engine.
