MIVEC (Mitsubishi Innovative Valve timing Electronic Control system) [1] is the brand name of a variable valve timing (VVT) engine technology developed by Mitsubishi Motors. MIVEC, as with other similar systems, varies the timing of the intake and exhaust camshafts which increases the power and torque output over a broad engine speed range ...
Mitsubishi Motors: Production: 2017–present: Layout; Configuration: 4-cylinder: Displacement: 1.5 L (1,499 cc) Cylinder bore: 75 mm (2.95 in) Piston stroke: 84.8 mm (3.34 in) Cylinder block material: Aluminum die cast: Cylinder head material: Aluminum die cast: Valvetrain: Direct acting DOHC, 16 valves, continuously variable MIVEC intake ...
The inlet camshaft position is advanced 25 degrees, thus increasing valve overlap. It remains in this advanced state until about 5000 rpm when the solenoid switches off, and the variator piston returns the valve timing to its natural state. The variable timing increases the engine's mid-range flexibility and reduces emissions.
The Mitsubishi 4G9 engine is a series of straight-4 automobile engines produced by Mitsubishi Motors. All are 16-valve, and use both single- and double- overhead camshaft heads. Some feature MIVEC variable valve timing , and it was the first modern gasoline direct injection engine upon its introduction in August 1996.
The 2.5-litre 6G73 is a 24-valve SOHC design with two valves running off a single cam lobe on the exhaust valves using a forked rocker arm and each intake valve actuated with two cam lobes, with a smaller bore than the 3.0L version of the same block. Bore and stroke are 83.5 mm × 76 mm (3.29 in × 2.99 in); it is a 60-degree V6 and weighs ...
The new 4J10 MIVEC engine features the use of a next-generation MIVEC system that continuously regulates intake valve lift, opening duration and timing. The new MIVEC system together with improved combustion stability and a reduction in piston friction provide an improvement in fuel economy without any loss in engine performance (output and ...
Mitsubishi's smallest powerplants, most commonly found in their earliest models in the 1960s: 1955-1962 — ME7/15/18 — This was Mitsubishi's first air-cooled OHV engine over one liter's displacement. In 1955, the 1276 cc ME7 was developed for the 1.5-tonne (3,310 lb) Mitsubishi TM7.
With traditional fixed valve timing, an engine will have a period of "valve overlap" at the end of the exhaust stroke, when both the intake and exhaust valves are open. The intake valve is opened before the exhaust gases have completely left the cylinder, and their considerable velocity assists in drawing in the fresh charge. Engine designers ...
