kilméterzámláló

A kilóméterzámláló, often referred to as an odometer, is an instrument that measures and records the distance traveled by a vehicle. It is a standard feature in virtually all automobiles and many other forms of transportation. The device typically displays the cumulative distance in kilometers or miles.

The concept of measuring distance traveled dates back to the early days of motoring. Early odometers were mechanical, utilizing a series of gears and rotating drums to increment the displayed distance with each rotation of the vehicle's wheels. As technology advanced, so did the odometer. Electronic odometers became prevalent, using sensors to detect wheel rotation and a digital display to show the distance. This shift offered greater accuracy and reliability.

The primary function of a kilóméterzámláló is to provide a record of a vehicle's usage. This information is crucial for several reasons. For vehicle owners, it helps in tracking maintenance schedules, as many service intervals are based on mileage. For buyers and sellers of used vehicles, the odometer reading is a key indicator of wear and tear and, consequently, the vehicle's value. Tampering with an odometer to falsely reduce the recorded mileage is illegal in most jurisdictions and is considered a form of fraud. Modern vehicles often have both a resettable trip odometer, which can be used to track distance for specific journeys, and a non-resettable, cumulative odometer.
