MIVEC (Mitsubishi Innovative Valve timing Electronic Control system) is the brand name of a variable valve timing engine technology developed by Mitsubishi Motors. MIVEC, as with other similar systems, varies the timing, lift and duration of the valves by using two different camshaft profiles. At low speeds, a mild (low-lift) cam lobe provides stable idle, lower emissions and increased torque at lower speeds, while above a fixed engine speed a second set of cam lobes are activated, providing higher lift and duration; therefore a greater quantity of air into the combustion chamber which increases the power and torque output over a broad engine speed range. MIVEC was first introduced in 1992 in their 4G92 powerplant, a 1, 597 cc naturally aspirated DOHC 16 valve straight-4. At the time, the first generation of the system was named Mitsubishi Innovative Valve timing and lift Electronic Control. The first cars to use this were the Mitsubishi Mirage hatchback and the Mitsubishi Lancer sedan.Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online.
