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.

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).
