Well Technically, Your All Wrong & They Just Simplify It For You To Understand It... There Are 4 Strokes In The Respect Of;
1. INTAKE
2. COMPRESSION
3. POWER
4. EXHAUST
But, There IS More Than One Cylinder In A Car.. The Four Cycles Cover The Entire Idle Revolution Of;
3=12. 4=16, 5=20 6=24 8=28, 10=32 12=36 16=40 Strokes Respectively Per Revolution Of Motor..
As I've Said, "A V6 CAN'T Run On Just One Cylinder..."
Do Your Research Thoroughly & You'll Then Understand My Reason...
Technically, The V6 Has 24 Strokes Of The Entire Engine, For The Motor To Revolve (4 Cycle "Piston Strokes" PER Cylinder)..
Technically, A Lawnmower IS A True 4 Stroke & IS Branded It For A Reason... It Has One Piston That Cycles 4 Times In The Entire Engine For It To Revolve...
So You ARE ALL Technically Wrong...
Well, your kinda close... But technically wrong
The V6 has 24 strokes in ONE engine CYCLE. TWO rotations of the CRANK.
Most engines of today operate on "Four Stroke" cycles. (Can also be known as "Four Cycle" Engines)
That refers only to the number of strokes for each piston to complete one cycle. Not the number of cycles completed. Regardless of how many cylinders are in the engine.
So, in one Engine Cycle, the V6 motor will have 24 Strokes of all 6 Pistons combined. (two revolutions of the crank). Whilst still being a "Four Stroke" Enigine.
Hope that clears it up a bit for you
So, in closing, the V6 IS a "Four Stroke" Engine. It takes "Four Strokes" for each piston to complete a cycle, it has 24 Strokes in an Engine Cycle.
