e=0l<Rj  
The 4G63 was a 1997 cc version. (85 mm bore x 88 mm stroke) SOHC and DOHC were produced. The DOHC version was introduced in 1987 in the Japanese market Galant VR-4 and came in turbocharged or naturally aspirated form. It is found in various models including the 1988-92 Galant VR-4 and the U.S. market 1990-1999 Eclipse, as well as the Mitsubishi Lancer Evolution I-IX. .r

The Mitsubishi Eclipse, Eagle Talon and Plymouth Laser introduced the DOHC turbocharged intercooled version to the U.S. in 1989 through Diamond Star Motors, a joint venture between Mitsubishi Motors and the Chrysler Corporation. From 1990 to late April 1992 came beefier connecting rods and the use of 6 bolts to secure the flywheel to the crankshaft; May 1992 to 2006 Evolution versions have lighter rods and use 7 bolts to secure the flywheel to the crankshaft. They are referred to as the "six bolt" and "seven bolt" engines, respectively. -x3tx7%

Its turbocharged variant, 4G63T (also sometimes referred to simply as the 4G63), has powered Mitsubishi vehicles in World Rally Championships for years in the Mitsubishi Galant VR-4, Lancer Evolution, Carisma GT and Lancer WRC04. It was the powerplant of the Lancer Evolution when Tommi Mäkinen won his four consecutive WRC championships in his Lancer. MHI and T-4 turbos were both used as power plants for these engines.

The 4G64 is the second largest variant, at 2,351 cc. Early models were 8-valve SOHC, but a later 16-valve SOHC and DOHC version was also produced. All used MPFI and had an 86.5 mm bore and 100 mm stroke. The 4G64 was later also available with gasoline direct injection. The version used in the Chrysler Sebring/Stratus coupes produced 152 hp (110 kW) at 5500 rpm with 162 ft·lbf (214 N·m) of torque at 4000 rpm. The Chrysler version features fracture-split forged powder metal connecting rods. The 4G64 is an interference motor like the 4G63, however, the early 8-valve 4G64 is a non interference engine.

The 4G69 is a 2378 cc version built in Shiga, Japan. Bore is 87 mm and stroke is 100 mm. Output is 162 hp (119 kW) at 5750 rpm (160 in the Sportback Wagon) with 162 ft·lbf (219 N·m) of torque at 4000 rpm. It has a cast iron engine block and an aluminum SOHC cylinder head. It uses multi-point fuel injection, has 4 valves per cylinder with roller followers and features forged steel connecting rods, a one-piece cast camshaft, and a cast aluminum intake manifold. The 4G69 incorporates Mitsubishi's MIVEC Variable Valve Timing technology. The 4G69 is an interference motor like the 4G63.

The Mitsubishi Orion or 4G1 engine is series of straight-4 internal combustion engines introduced by Mitsubishi Motors in the 1970s, along with the Astron, Sirius, and Saturn. It was introduced in the Colt and Colt-derived models in 1978. Displacement ranges from 1.2 L to 1.6 L. 6Ss{+MF|v

The Mitsubishi Neptune or 4G4 engine is a series of iron-block OHV straight-4 engines built by Mitsubishi Motors from 1971 to 1979, alongside the Orion, Saturn, Astron and Sirius. This was to be Mitsubishi's last OHV engine. The inability to clear new emissions rules for 1978 meant that the Neptunes were replaced by the 4G1 Orion. bS<@Rd{g

The Mitsubishi Astron or 4G5 engine, is a series of straight-4 internal combustion engines first built by Mitsubishi Motors in 1972. Engine displacement ranged from 1.8 to 2.6 litres, making it one of the largest four-cylinder engines of its time. DLY

It employed a hemispherical cylinder head, chain-driven single overhead camshaft (SOHC) and eight valves (two per cylinder). United States passenger car versions had a small secondary intake valve referred to as the "Jet Valve". This valve induced swirl in the intake charge, enabling the use of leaner fuel/air mixtures for lower emissions. It was designed as a cartridge containing the valve spring and seat which simply screwed into a threaded hole in the head, similar to a spark plug but inside the cam cover. The rocker arms for the intake valve were widened on the valve end to accommodate the cartridge, which was equipped with a very soft valve spring in order to avoid wear on the camshaft intake lobe. Modifications to the head were thereby reduced as the Jet Valve negated the necessity for a three-valve-per-cylinder design.[1]

In 1975, the Astron 80 introduced a system dubbed "Silent Shaft": the first use of twin balance shafts in a modern engine. It followed the designs of Frederick Lanchester, whose original patents Mitsubishi had obtained, and proved influential as Fiat/Lancia, Saab and Porsche all licenced this technology. Y_@"v# ,

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. m0A#6=<

The Mitsubishi 4A3 engine is a range of alloy-headed inline four-cylinder engines from Mitsubishi Motors, introduced in 1993 in the sixth generation of their Mitsubishi Minica kei car. 9e~WK720=  
A 1.1 L version was made available in 1999 for bigger cars, and was subsequently fitted to the Mitsubishi Pistachio, a limited production car based on the kei class Minica, equipped with the company's Automatic Stop-Go (ASG) system for cutting the engine when idling. So equipped, the Pistachio was able to record fuel economy figures of 30 km/L. 6 xarYh(

4A9 EMlIxpCn:  
The Mitsubishi 4A9 engine is the newest family range of all-alloy inline four-cylinder engines from Mitsubishi Motors, introduced in the 2004 version of their Mitsubishi Colt supermini, and built by DaimlerChrysler-owned MDC Power in Germany (previously a joint venture).[1][2] +8AvTSgX%  
The engine project was begun as a joint effort by Mitsubishi Motors and DaimlerChrysler (DCX), with Mitsubishi handling the development of the engines and MDC Power GmbH, a company previously jointly established by Mitsubishi and DCX, handling production. The 4A9 is Mitsubishi's first four-cylinder engine family to adopt a high-pressure die-cast aluminum block.[1][3] cy|%sf`  
All engines developed within this family have aluminum cylinder block and head, four valves per cylinder, double overhead camshaft layouts, and MIVEC continuous variable valve timing (intake only). sDC*J\X

The Mitsubishi 4B1 engine is a range of all-alloy straight-4 engines built at Mitsubishi's Japanese "World Engine" powertrain plant in Shiga on the basis of the Global Engine Manufacturing Alliance (GEMA).[1][2][3] Although the basic designs of the various engines are the same, their exact specifications are individually tailored for each partner (Chrysler, Mitsubishi, and Hyundai). The cylinder block and other basic structural parts of the engine were jointly developed by the GEMA companies, but the intake and exhaust manifolds, the cylinder head’s intake and exhaust ports, and other elements related to engine tuning were independently developed by Mitsubishi.
