What A meter fixed to a vehicle that measures and displays its speed?
In most vehicles it is a speedometer; in commercial vehicles a tachograph is used. The tachograph not only measures and displays the speed but also records the distance and speed driven over time; it is also more accurate than those in cars with an error of about 1-2% whereas those in cars are only accurate to about 10% and generally over estimate speed. They are checked every 2 years for calibration and recalibrated every 6 years unlike those in cars.
Is 4 cylinder equals 3000 Cm3 in a car?
Not exactly having 4 cylinders doesn’t automatically mean the engine is 3000 cm³. Engine size depends on the volume of each cylinder, so a 4-cylinder engine could be anywhere from around 1000 cm³ up to over 2500 cm³ depending on the car. For example, when cars come in for routine checks at Metrowest Car Service, the mechanics often point out that two cars with the same cylinder count can have very different engine sizes and performance. Are you asking this because you’re looking at a specific car, or just curious about how engine sizes work?
