<p><span class="point">1. Intake:</span> Also known as induction or suction. This stroke of the piston
begins at top dead center (T.D.C.) and ends at bottom dead center (B.D.C.). In this stroke the
intake valve must be in the open position while the piston pulls an air-fuel mixture into the
cylinder by producing a partial vacuum (negative pressure) in the cylinder through its downward
motion.</p>
</div>
<div class="boxes">
<p><span class="point">2. Compression: </span> This stroke begins at B.D.C, or just at the end of the
suction stroke, and ends at T.D.C. In this stroke the piston compresses the air-fuel mixture in
preparation for ignition during the power stroke (below). Both the intake and exhaust valves are
closed during this stage</p>
</div>
<div class="boxes">
<p> <span class="point">3. Combustion:</span> Also known as power or ignition. This is the start of the
second revolution of the four stroke cycle. At this point the crankshaft has completed a full 360
degree revolution. While the piston is at T.D.C. (the end of the compression stroke) the compressed
air-fuel mixture is ignited by a spark plug (in a gasoline engine) or by heat generated by high
compression (diesel engines), forcefully returning the piston to B.D.C. This stroke produces
mechanical work from the engine to turn the crankshaft.</p>
</div>
<div class="boxes">
<p><span class="point">4. Exhaust:</span> Also known as outlet. During the exhaust stroke, the piston, once
again, returns from B.D.C. to T.D.C. while the exhaust valve is open. This action expels the spent
air-fuel mixture through the exhaust port.</p>
