(S)GM(W) ENGINES IN CHINA AND ELSEWHERE

As soon as Shanghai General Motors started building cars in 1999, it developed varieties of existing engines, such as 2.5 and 3.0 versions of the 60° V6 engine. For specific details and model applications, see On a Global Mission: The Automobiles of General Motors International

SGM(W) multi-port DOHC 4-valve engines:

Modelled after Opel engines, arrived in 2010 SGM’s own engine family with unique bore and stroke dimensions, at first in the Chevrolet Sail, the first SGM-developed car. This 1399cc engine, that China also fitted in its 2011 Aveo, differed from the Daewoo 1399cc, and of course also from the later SGE engine family variant.

Likewise, the 1349cc variant in the 2015 Chevrolet Sail3 should not be confused with the 1349cc in the Daewoo Lanos, nor with the 1349cc in the later dual injection engine family.

The 1485cc engine arrived in August 2011 in the Baojun 630, and became a hit in numerous variants, with double variable valve timing added, and fitted in most Baojuns and Wulings and various entry-level Buick and Chevrolet models, and also in the Uzbek-built Daewoo Gentra/Chevrolet Lacetti.

The 1372cc turbo variant replaced the imported 1364cc engine in the Buick Encore in mid-2013 and had similar output specifications but with the torque revs starting at 1700 instead of 1850 rpm due to a split turbocharger, with the engine boost bypass channel directly controlled by a solenoid valve.

In 2016 arrived a 1451cc turbo variety with the torque increased from 200 to 230 Nm for the Baojun 730 and 560, to which Baojun developed one with 250 Nm to cope with a CVT. This engine employs a new highly efficient combustion system. The engine’s optimized intake duct’s tumble ratio has been increased from 1.8 to 2.35. This produces greater intake pressure and a higher compression ratio, further reducing the engine’s fuel consumption by 10 percent.

Liuzhou Saike Technology direct injection DOHC 4-valve engines:

This engine, currently dubbed ‘280T’, introduced direct injection to SGMW, starting with the Baojun RS-5 300T in June 2020 and at the end of that year with the inofficial Baojun RS-7 SUV, and by 2022 in the Wuling Victory. The 3-cylinder 1199cc ‘245T’ is in the inofficial Baojun RS-5 PHEV, and was also intended for the RS-3.

SGM/SAIC dual injection DOHC 4-valve engines:

This family, part of the SAIC-GM-the-eighth-generation Ecotec brand, was conceived for Shanghai GM, also for usage by SAIC in their Roewe/MG/Maxus models. This twin-jet engine uses port (indirect) injectors only, but closer to the valves.

A 999cc variation with direct injection arrived in April 2019 in the Chinese market Onix, not to be confused with the 4-cylinder OHC 999cc engine in the previous generation Onix, at that time still available in South America, and replaced late in 2019 (a DOHC variant was available in the Brazilian Corsa around the turn of the millennium, see 'On a Global Mission', Volume 2). Both 999cc DOHC engines stopped being offered in China by 2022.

Another 3-cylinder 999cc engine, with different bore and stroke dimensions is used in the SGE family (see hereunder), but in China only by MG/Roewe.

Wuling Liuji-developed DOHC 4-valve engine:

This engine is said to have been modelled after Toyota's alloy 1ZZ-FE engine (arriving in the 1998 American Corolla and Chevrolet Prizm), using its bore and stroke, but quoting a more optimistic 1798cc. This engine became superfluous for Baojun in mid-2016 at the release of the 1451cc turbo, and was abandoned (with automatic clutch) in autumn 2018 at the release of the CVT transmission in the 1.5 turbo. It continues in the Rongguang pickup.

Wuling Liuji-developed Atkinson DOHC 4-valve engine:

The LJM20A engine is combined with electric motors, creating hybrid variations of the Wuling Xingchen Asta and (yet to come) Victory. The LJP60 HEV hybrid assembly units by Wuling Liuji, a subsidiary of Guangxi Automobile Group, has commenced scale production in May 2022. The launch of the HEV hybrid assembly units marked the breakthrough of the division from a traditional fuel engine manufacturer to a multi-dimensional vehicles’ power system supplier extending to the business segment of different types of new energy vehicle. Wuling’s HEV hybrid is not the P2 combination of the previous CVT + motor, nor the multi-gear structure of SAIC.

The non-hybrid LJM20B engine came in the Wuling Zhengcheng by September 2022.

Guangxi Automobile Group, established in May 2015, and previously known as Liuzhou Wuling Motors Co., Ltd., completed relocation of its special vehicle project, and its new NEV manufacturing site started production in October 2021. The company was originally owned by the state government but it turned into a mixed-ownership enterprise by accepting private capitals.

SGE 4-cylinder DOHC 4-valve engines:

This engine family with central direct injection was mainly conceived by Opel, and used worldwide by General Motors and by SAIC, that used the same technology for their larger MGE engine range. All share the same bore of 74 mm, with a bore pitch (spacing between the cylinders) of 81 mm.

Note, that Vauxhall advertised the Adam to have 998cc, not to be confused with the 3-cylinder DOHC engine that was used up to 2014 in the Corsa. Actually, the SGE 3-cylinder has 998⅔cc. In a country like Japan, it is practice to round down the decimal in any case, resulting in differences between domestic and export cc quotations.

Where SGM has started a new generation 1.5 turbo engines of their own in the Buick Verano Pro in September 2021 (with dual fast cam phasers, see hereunder), SAIC Motor launched their NF1 engine, developed from the SGE, in August 2019 in the Roewe RX5 MAX, equipped with a 35 MPa high-pressure fuel injection system.

GM in America launched the LSD variant in September 2022, also with a higher-pressure fuel system (35 MPa from 20 MPa).
