Bir otomobil motorunda yak\u0131t-hava kar\u0131\u015f\u0131m\u0131 silindir i\u00e7inde ate\u015flendi\u011finde geni\u015fleyen gazlar pistonu\u00a0a\u015fa\u011f\u0131ya iterek piston koluna (biyel) ba\u011fl\u0131 olan krank milini d\u00f6nd\u00fcr\u00fcr. Bu buhar makinas\u0131nda, y\u00fcksek\u00a0bas\u0131n\u00e7l\u0131 buhar silindirin bir ucundan girerek pistonu iter.
