INTAKE

Almost all cars currently use what is called a  four-stroke combustion cycle  to convert gasoline into motion. The four-stroke approach is also known as the  Otto cycle , in honor of Nikolaus Otto, who invented it in 1867.

Presentation Transcript

  1. Almost all cars currently use what is called a four-stroke combustion cycle to convert gasoline into motion. The four-stroke approach is also known as the Otto cycle, in honor of Nikolaus Otto, who invented it in 1867.

  2. The piston starts at the top, the intake valve opens, and the piston moves down to let the engine take in a cylinder-full of air and gasoline. This is the intake stroke. Only the tiniest drop of gasoline needs to be mixed into the air for this to work. INTAKE

  3. COMPRESSION Then the piston moves back up to compress this fuel/air mixture. Compression makes the explosion more powerful.

  4. COMBUSTION When the piston reaches the top of its stroke, the spark plug emits a spark to ignite the gasoline. The gasoline charge in the cylinder explodes, driving the piston down.

  5. EXHAUST Once the piston hits the bottom of its stroke, the exhaust valve opens and the exhaust leaves the cylinder to go out the tailpipe.

  6. The scheme and the order of the 4-TH cylinder engine

  7. Systems and mechanisms for internal combustion engines CRM Lubrication system supply system GDM cooling system The starting system (diesel) Ignition system (carburettor engines)
