A multi-valve or multivalve engine is one where each cylinder has more than two valves (an intake, and an exhaust). A multi-valve engine has better breathing, and with more smaller valves (having less mass in motion) may be able to operate at higher revolutions per minute (RPM) than a two-valve engine, delivering more power.[1][2]
