OTTO CYCLE (Four strokes)
Intake / Induction stroke
Intake
The piston descends and reduce the pressure.
Fuel and air is forced into the cylinder
The intake valve then close.

Ignition of fuel and Power stroke
OTTO CYCLE (Four strokes)
Ignition and power stroke
The air-fuel mixtured is ignited by an sparkplug.
The resulting expansion of burning gases pushes the piston downward

CONCLUSION
OTTO CYCLE WAS PROBABLY THE GREATEST INVENTIONT FOR TRANSPORTATION IN THE 19TH CENTURY AND IT IS THE MOST COMMON ENGINE NOWADAYS.
AUTOMOBILE INSDUSTRY SHOULD TRY TO FIND THE WAY TO REDUCE THE AIR POLLUTION GENERATED BY CARS, LOOKING FOR OTHERS LESS POLLUTING FUELS OR TROUGHT THE INVENTION OF HYBRID CARS AS SOON AS POSSIBLE.
