What is 4G63?

1,4G63

After ten generations thrive, Mitsubishi EVO already evolved enough to perfect, whether it is achieved through in the WRC arena brilliant record or stay in the hearts of fans as well as lovers of modification the sacred image, which have witnessed the legendary history of nearly 20 years. However, in the history of the evolution of one to nine generations of EVO, the body has changed, tail changed, we changed the chassis, the gearbox has changed …… The only constant is that Taiwan work diligently, and constantly self-improvement 4G63 engine.
4G63 named
Mitsubishi from 1964 began to design their own manufacturing automobile engines, to the 1970s, it began to use “English + digit + a two-digit number” of naming method. 4G63 in “4” represents the number of cylinders; “G” stands for a gasoline engine, (D representative of a diesel engine, B is the use of said aluminum alloy engine cylinder, EVO ten generations 4B11 engine is all-aluminum); “6” family is the number of the engine, and “3” is the number within the family. 4G6 series engine can be regarded as mayor in the Mitsubishi depot, its predecessor is 4G5 series, first appeared 4G6 series engine is 4G62, and 4G63 it did not appear until 1984.

In 1992, the most in Mitsubishi to create a civilian car on the basis of the Mitsubishi LANCER sport models, it is the first generation of EVO. Although the EVO 4G63 age difference of 8 years old, but that does not prevent the two final “tied the knot.” Of course, red head mounted on the EVO 4G63 not the same as the civilian version of the 4G63.
4G63 this red head initially mounted on a Mitsubishi GALANTVR4 models, which becomes a civilian version sOHC DOHC dual overhead camshaft. An engine intake air are not the same, the civilian version of the naturally aspirated, and the EVO Edition provides a turbocharger. These two improvements brought about by the peripheral devices and components to upgrade is also very different, which involves the engine management system, cooling system, ignition system and the like.

4G63 original design can be developed with intention EVO models coincide, as 4G63 engine uses a different stroke (88mm) larger than the bore (85mm) long-stroke design. Mitsubishi’s technical staff believe that high power output engine speed range is too narrow, that the driver of a higher technical requirements, but this design is not suitable for rallying. However, the design contributes to long stroke in the low speed range to obtain a large torque output, and because the speed is not high, so the durability of the engine is relatively high, which makes the machine little Mitsubishi rally cars in the race failure occurs.
4G63 engine uses more common that era cast iron cylinder with turbocharger and long stroke design, laid the foundation for it can easily surpass 400N · m, while the specially tuned for the WRC event is to make it reaches a peak torque of 550N · m, while the mechanical durability is also provided a broad space for modification enthusiasts.

4G63 from good infrastructure, such that the EVO in the first generation can reach 250 horsepower and the power output of 315N · m. After nine generations of evolution EVO cars, 4G63 engine are the times, to some extent, it can be said that around the EVO evolution 4G63 carried out. But no matter how changes in engine peripheral parts, the basic structure remains unchanged 4G63 is, in particular, long-stroke design is preserved. Thus, to produce a classic engine, the initial design idea how important it is.
With the evolution of the structure of the EVO is changing 4G63

Maximum power aspect, the horsepower generation EVO250 basis, after each generation model will be a slight increase of about 10 horsepower, until the fourth generation EVO reached the upper limit power output between Japanese car prices established by an unwritten –280 horsepower. After capping the maximum power, and technical personnel to turn the potential of mining 4G63 steering torque output until the ninth generation EVO jumped to 400N · m.
associated with each model generation, 4G63 structure also occur with minor changes. E previous generationsVO engine compression ratio of 8.5, to the third generation is raised to 9, for 4G63 redesigned piston, turbine, but also with peripheral components has been enhanced, in particular, the cooling system is enhanced. Five of the piston EVO and lightweight process, increases the turbine diameter, six generations piston intensive again, while taking advantage of the way the forced cooling oil to reduce the temperature at the piston, so as to enhance the anti-knocking ability piston, while We started with the titanium alloy material of the sixth generation turbine EVO, which greatly reduces the hysteresis of the turbine. After seven or eight generations EVO are a big issue around the turbine, and in the universal application of the backdrop valve timing technology, Mitsubishi will own eight-generation MIVEC technology implanted into the EVO, a step closer to excavate the 4G63 limit. Therefore we can say, 4G63 aggressive created a synchronous forward the EVO.

However, no matter how change, 4G63 still has a “grassroots” class identity of the engine. But its greatest charm lies unfathomable potential for conversion, only the lifting of restrictions the ECU, slightly modified exhaust and ignition system enhancements, you can break 300 horsepower at once. If further investment can easily break 400 horsepower, while those from Japan JUN, HKS and other professional tuning the launch of the conversion kit, you can make it a power boost to 700 horsepower or more.
With the EVO one to nine generations of change, 4G63 also starting to prove the old state, even if the application of Mitsubishi’s MIVEC technology, still can not make up for the old design and emission failure of the state. As rival Mitsubishi EVO WRC in the game as well as civilian car market – Subaru ImprezaSTI, it completed the level 2.0L to 2.5L displacement opposed 4-cylinder engine upgrade in 2005. As a direct competitor, Mitsubishi also announced that the tenth generation EVO will no longer be using 4G63 engine. So far, the ninth generation EVO are equipped with the 4G63 has also become eternal farewell.
into the domestic production of 4G63
Although the EVO 4G63 is no longer the only, but engine still has its own value in the civilian market. In 2001, Shenyang Aerospace Mitsubishi Motors Engine Co., Ltd., in the form of technology transfer will 4G63 introduction of the domestic production. However, the introduction of domestic rawProduction is relatively simplified version, which uses naturally aspirated mode, and a single overhead camshaft, and the most important point is that the EFI system to the engine by the mechanical carburetor.

In infrastructure, the introduction of 4G63 no difference between the 1990s domestic 4G63 Ibid century, which also determines it is very rugged and durable, the original Brilliance Grandeur sedan launched ten years 200,000 km warranty policy, perhaps spotted this machine not a problem. Furthermore Mitsubishi Galant, Imperial EC8, Great Wall Hover H6, Chery Eastar models are also equipped with a domestic 4G63 engine.

summary: [123 ] at Mitsubishi EVO from the first generation to the ninth generation of 14 years, 4G63 engine always as its best partner, this phenomenon can be described as rare. However 4G63 engine is also in the process of evolution, almost perfect. But you also hard to tell in the end who made a star who, as always EVO 4G63 and indivisible whole, whether or EVO 4G63, their most glorious years is that period in close cooperation with each other.
