(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 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. 

Similarly, 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.

SGM/SAIC dual injection DOHC 4-valve engines:

This family 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 to be 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).

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.

GM global E-Turbo engine:

The first application of this global engine family in 3-cylinder form arrived in November 2018 in the South Korean Malibu.  For China it was developed to meet the “National Six B” emission standard, but only 9 engine system durability tests and a number of vehicle durability tests were conducted in China.

The E-Turbo engine reduces energy loss by applying cutting-edge electric technologies, including a new electric water pump that effectively controls the interior temperature of the engine, an electric wastegate system that maximizes the efficiency of the turbocharger, and a new electro-hydraulic brake system that replaces the mechanical vacuum booster to lessen the burden on the engine.

In late 2019 it found its way to the 2020 Opel/Vauxhall Astra as well.

SGMW-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 altogether (with automatic clutch) in autumn 2018 at the release of the CVT transmission in the 1.5 turbo, and after the Wuling Zhengcheng people mover had stopped production in April 2017.

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 998cc.  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.
