Suck ... Squeeze ... Bang ... Blow
Today, cars, trucks, motorcycles, construction machinery and many others most commonly use a "four-stroke" cycle internal combustion engine (ICE). The four strokes refer to intake, compression, combustion and exhaust strokes that occur during two crankshaft rotations per working cycle of the engine. The four steps in this cycle are often informally referred to as "suck ... squeeze ... bang ... blow."
Now, next time you attend a boring cocktail hour, or finger-tapping, eye-brow raising corporate meeting, you can break the ice and impress your friends and associates with your knowledge of the internal combustion engine ... and the creative terminology you've come up with to describe it.
So, without further ado, let's take a close look at what is going on inside your vehicle's engine ... (Read Discussion)

4-Stroke Cycle #993230Jim Baines September 06, 2008
( SUCK) INTAKE ~ The intake stroke begins with the piston near the top of its travel. As the piston begins its descent, the exhaust valve closes fully, the intake valve opens and the volume of the combustion chamber begins to increase, creating a vacuum (thus the term SUCK for this cycle). As the piston descends, an air/fuel mixture is drawn from the fuel injectors into the cylinder through the intake manifold. The intake stroke ends with the intake valve closed just after the piston has begun its upstroke.Shirley Sicurello September 06, 2008
Thanks for the info, Jim! I am in the process of buying a Honda motorcycle, so this was interesting as I don't understand mechanics at all! #6418360Deb Koskovich September 06, 2008
Wow, I love the surreal artsy look of this, Jim! #6418449Mike Clime September 06, 2008

Beautiful capture Jim. I will write you when I have time. Want to tell you about a Harley I was going to by and almost got killed on the way to trade my Honda in on it. Back in 83. Bill #6421137Barbara Waldoch September 07, 2008
