  • 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. While the conventional 4G92 engine provided 145 PS (107 kW; 143 hp) at 7000 rpm, the MIVEC-equipped engine could achieve 175 PS (129 kW; 173 hp) at 7500 rpm. Similar improvements were seen when the technology was applied to the 1994 Mitsubishi FTO, whose top-spec GPX variant had a 6A12 1997 cc DOHC 24 valve V6 with peak power of 200 PS (147 kW; 197 hp) at 7500 rpm. The GR model, whose otherwise identical powerplant was not MIVEC-equipped, produced 180 PS (132 kW; 178 hp) at 7000 rpm by comparison. Although initially designed to enhance performance, the system has subsequently been developed to improve economy and emissions, and has been introduced across Mitsubishi's range of vehicles, from the i kei car to the high-performance Lancer Evolution sedan.
  • Il MIVEC (Mitsubishi Innovative Valve Control sistema di cronometraggio elettronico) è il nome di una tecnologia sviluppata da Mitsubishi Motors. per la variazione della fasatura delle valvole, come gli altri sistemi simili, varia i tempi, ascensore (alzata) e durata delle valvole con l'adozione di un albero a camme munito di due diversi profili. Ai bassi regimi, si ha una camma con un profilo lieve (ridotta alzata), fornendo stabilità, riduzione delle emissioni e maggiore coppia a ai bassi regimi, mentre sopra di un determinato regime del motore, si ha l'attivazione di un secondo set di lobi, fornendo un'alzata maggiore e di durata superiore, quindi una maggiore quantità d'aria nella camera di combustione, aumentando la potenza e la coppia di uscita, per un ampio intervallo di regimi motore. Da 4B1 famiglia di motori in poi, MIVEC ha pienamente evoluta in una variabile continua della valvola di sistema (Dual VVT sulle valvole di aspirazione e scarico), il MIVEC incorporato nella famiglia motori 3B2, 3A9 e 4A9 varia continuamente solo le valvole d'aspirazione, in altri sistemi piu vecchi si variava solo la fasatura della valvola a seconda del regime motore, ma non si modificava la sua alzata.

Впервые представлена в двигателе 4G92 (англ. ), под названием Mitsubishi Innovative Valve timing and lift Electronic Control. Применение MIVEC позволило увеличить мощность двигателя со 145 л. с. (при 7000 об. ) до 175 л. с. (при 7500 об.). Первым автомобилем с изпользованием этой системы стал Mitsubishi Mirage в кузове хэтчбек. В настоящее время широко применяется в двигателях Mitsubishi от компактных моделей i до Lancer Evolution.
