the cylinder
- In its simplest form this is a tube of circular cross-section closed at one
end - It is a part of the crankshaft
- it is fitted in the crankpin
- It connects the piston to the crankshaft.
the piston
- It couples the piston and the connecting rod together.
- In its simplest form this is a tube of circular cross-section closed at one
end. - It fits closely inside the cylinder.
- In the second and third phase is closed
The connecting rod
- It connects the piston to the crankshaft
- It is the main shaft of the engine
- It is carried in bearings
- In its simplest form is a tube of circular cross-section
The crankshaft
- It is free to turn inside the crankpin.
- It is the main shaft of the engine and is carried in bearing.
- It is fitted in the crank pin
- It couples the piston and the connecting rod together
The inlet poppet valve
- In the first phase is open
- in the second phase is closed
- In the second and in the third phase is
open - In the fourth phase is closed
The compression stroke
- It is the first phase
- It is the second phase
- It is the third phase
- It is the fourth phase
Both of the valves are closed
- In the first and second phase.
- In the first and third phase
- In the third and fourth phase
- In the second and third phase
