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 ...
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.
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 ...
A water flow timer using a ball valve contains an electric motor with gears to stop or start the water flow by turning a perforated ball within the water flow line. The gearbox in a ball valve timer makes a rumbling sound when actuated. The solenoid type switching timers contain a solenoid that relieves pressure on a diaphragm in the water-flow ...
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 ...
A 12-valve version (two intake and one exhausts per cylinder) of the 1468 cc 4G15 engine. It entered production in 1989, for the third generation Mitsubishi Mirage / Lancer . It was available with a carburettor or fuel injection, producing 85 or 100 PS (63 or 74 kW) in Japanese market trim at the time of introduction. [ 6 ]
Mitsubishi increased the combustion efficiency by optimizing the design of the cylinder head intake and exhaust ports, by incorporating the MIVEC system on both intake and exhaust valves and by using injectors that give an ultra micro droplet fuel spray. To lower the engine's weight, Mitsubishi used die-cast aluminium for the cylinder block ...
Together with Mitsubishi's electric vehicle technology the new diesel engines are positioned as a core element in the Mitsubishi Motors Environment Initiative Program 2010 (EIP 2010) announced in July 2006. [3] [9] The 4N1 engine family is the world's first to feature a variable valve timing (intake side) system applied to passenger car diesel ...
