Mitsubishi 4G63 engine

Engine displacement of 1997 cm3, in-line 4 cylinder. It has a cast-iron block and an aluminum alloy cylinder head with a gas distribution system SOHC or DOHC - with one or two camshafts, 8 (12) or 16 valves. Two balancing shafts are installed in the unit, which rotate in antiphase, "to reduce third-order vibrations." It was installed both longitudinally and transversely, after modification to the other side by pulleys. It could be a carburetor (mikuni, solex, weber), two carburetor (lancer ex2000 rally), single injection (two electric injectors in the throttle body), injection (ECI-multi injection).

“Mitsubishi Introduces New MCA-Jet Low Pollution Engines”

The first engines were introduced in 1975 on the Mitsubishi Galant / Galant Lambda / Galant Sigma / Sapporo / Delica / Celeste models. The first was developed engine G62B , 1850 cm3. Immediately behind it appeared the G63B, which differed only in volume, cylinder diameter and one casting on the block. In 1980, a turbocharged mono-injection version with 12 valves appeared; it was installed on the Lancer EX2000 and Galant Lambda / Sapporo, Starion, Tredia, Cordia. In 1984, the first 8-valve injection engine was introduced, then the next largest 4G64 -G64B motor appeared in the lineup (the difference is the cylinder diameters and the piston stroke due to the crankshaft, the block is slightly higher and wider). In various modifications, the G63B existed on different models until 1986-88, after which the Sirius range of motors was renamed to 4G63 and significantly modified, DOHC versions appeared, power and environmental restrictions increased. In 1986, the first DOHC engine and immediately, on a rally car - turbocharged DOHC. With the renaming of the engine, the modification of 8 and 12 valves (SOHC) single injection was discontinued. Then, in 1986-87, there appeared engines of 16 DOHC 4G62 / 1800 cm3, 4G61 / 1600 cm3, 4G67 / 1800 cm3 valves, which were a small copy of 4G63, and cylinder head motors on 4G62 and 4G67 DOHC engines were completely identical to 4G63 .

In 1993, the motor was significantly changed for the first time - a mod appeared. with fastening the flywheel to the crankshaft with 7 bolts. In parallel, the old 6-bolt modification continued to be put on various cars. The sunset of 8 valve versions can be called a tightening of global environmental standards, and the effect of globalization, motors were needed not for 15 years but for 7. The last 8 valve injection version was 1993, the carburetor lasted longer due to its cheapness and reliability - on commercial models until 1998 years complying with Euro-3. In 1995, the 7-bolt modification was labeled 4G63T , another cylinder head DOHC (so-called square head) and a turbocharged version. In 1997, the 6-bolt version of the DOHC turbocharged injector was discontinued. In 2003, a 7-bolt modification with the MIVEC system was introduced.

It is also worth mentioning third-party manufacturers that entered into alliances with MITSUBISHI MOTORS in different years and made this engine out of them on their machines in various modifications. Among them are Chrysler, Dodge, Plymouth, Eagle / AMC, Mazda, Proton, Hyundai, Kia, Great wall, CMC, Chery. The most used engine was HYUNDAI , and the Stellar model since 1985, in 1996, HYUNDAI, with the help of its partner MITSUBISHI MOTORS, used the 4G63 cylinder head and 4G64 cylinder block to create their new 2.4-liter engine for installation on a Hyundai Sonata car from 1998 to 2005 and for the Kia Optima from 2000 to 2004. For Korean manufacturers, it is labeled as G4JS . Unchanged 4G63 among other manufacturers lasted the longest on Hyundai Sonata until 1994, and is still being produced by Chinese manufacturers.

The interval from 1992 to 1997 produced the most diverse versions of this engine, it is worth noting some of the most unusual for the engine that gained fame in rallies and races. version 7-bolt deformed SOHC 16 valve with carburetor, mounted on Canter, L300, Delica. and version 7-bolt SOHC 16 valve with an injector with a distributor transferred to the camshaft gear.
