Engine animations

Post by Scott - A2A »

All of our Accu-Sim aircraft have 4-stroke engines.

FOUR STROKE ENGINE
Intake Stroke: Opens intake valve, piston moves down, pulling in air/fuel mixture.
Compression Stroke: Intake and exhaust valves closed, piston moves up compression air / fuel mixture.
Power Stroke: Spark ignites the compressed air / fuel mixture, and explosion pushes piston down, creating the force that turns the crankshaft
Exhaust Stroke: Exhaust valve opens, piston moves up expelling remnants from the prior explosion


Here is a nice animation of a radial engine (The P-47 Thunderbolt has a radial engine). This anim shows the grace of the combustion engine.

My flight instructor used to say Suck Squeeze Bang Blow referring to the 4 stroke cycle. Sounds just dirty enough for you to remember it.

Ha - a radial engine always looks like it is 'getting it's groove on' when viewed like this :P

Suck Squeeze Bang Blow - yep great basic analogy, cool thing is it is exactly the same analogy for a turbine engine!

Aye, 4 strokes, 5 events. Can anyone name the 5th?

Correct. This is often overlooked but critical step and the engine is timed to have this happen at a specific moment in the 4 stroke process. Everyone knows it happens but, not many people think about it.
