The engine weight has been reduced by 12 kg (26 lb) compared to the 4G63, even with the addition of a timing chain instead of a belt and MIVEC continuous variable valve timing on both the intake and exhaust camshafts (the 4G63 had MIVEC valve timing & lift switching type on the intake only). A revised turbocharger offers up to 20-percent ...
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 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 torque) over the 4B10 MIVEC engine (1.8-liter, inline-4, 16-valve DOHC).
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.
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 . The 1145 cc ME15 and the 1489 cc ME18 were premiered in 1958 for the TM15/16 and TM17/18 trucks; production of this engine series ended when Mitsubishi ...
The 4G69 incorporates Mitsubishi's MIVEC Variable Valve Timing technology. Mitsubishi ceased any further development and production of Sirius engine after 2012 model year, and its Chinese joint-venture, Shenyang Aerospace Mitsubishi Motors Engine Manufacturing Co., is now the only one producing 4G69 engines.
Mitsubishi's new clean diesel engines use a 200 MPa (2,000 bar) high-pressure common rail injection system to improve combustion efficiency. The 4N13 1.8 L (1,798 cc) uses solenoid fuel-injectors. The larger 4N14 2.3 L (2,268 cc) engine uses piezo fuel-injectors that produce a finer fuel spray. Both engines feature a fast ceramic glowplug system.
The 3-litre V6 is the most commonly used engine; it produces 175 hp (130 kW; 177 PS) at 5,000 rpm. [6] The North American market received petrol V6 engines during all years of production while a petrol 2.4-litre engine was offered on base models from 1997 through 1999 in the United States and for additional years in Canada.
