TheGM Family Iis astraight-four piston enginethat was developed byOpel,a former subsidiary ofGeneral Motorsand now a subsidiary ofPSA Group,to replace the Vauxhall OHV,Opel OHVand the smaller capacityOpel CIHengines for use on small to mid-range cars fromOpel/Vauxhall.The engine first appeared in theOpel Kadett Din 1979, and shortly afterwards in its Vauxhall badged sister – theVauxhall Astra Mk.1in 1980. Despite this, the previous Opel OHV engine continued to be sold in entry level versions of the Opel Kadett/Astra and Corsa throughout the 1980s.

The Family I is informally known as the "small block", since it shares its basic design and architecture with the largerFamily IIunit (correspondingly known as the "large block" ), which covers the mid range and higher engine capacities up to 2400cc.

Originally produced at theAspern engine plant,production was moved to the Szentgotthárd engine plant inHungary^[2]with the introduction of the DOHC version.GM do BrasilatSão José dos Campos,^[3]GMDATatBupyeongandGM North AmericaatTolucaalso build these engines. The Family II units, by contrast were manufactured byHoldenin Australia.

Design

TheFamily 1engines are inline-four cylinder engines with belt-driven single or double overhead camshafts in an aluminumcylinder headwith acast iron engine block.GM do Brasil versions were also capable of running on ethanol. These engines share their basic design with the largerFamily IIengine – for this reason some consider the Family I and Family II to be the same series and instead use the terms 'small block' and 'large block' to distinguish between the two. Over the years there has been overlap between the two types as the smallest capacities of the Family II have also been manufactured with larger capacity versions of the Family I block.

Early build versions of the engine gained a notorious reputation for camshaft and follower failure – this was largely due to a special lubricant being used in the engine during the running in period, which would be changed for conventional oil at the first service. Many owners (familiar with the servicing requirements of the older overhead valve units that the Family I/II replaced) would often exacerbate the problem by changing the oil themselves within the running in period. Opel solved the problem by improving the metallurgy of the camshaft and followers, and changing the lubrication specification. Another issue (also common to the Family II), revolved around the water pump, which sits in an eccentric shaped housing and doubles as the timing belt tensioner. If poor quality antifreeze (or if no antifreeze was used), corrosion would jam the water pump in its housing making it impossible to tension the belt. Later versions of the engine incorporate a separate tensioning/jockey pulley for tensioning the belt.

GM do Brasilspecializes inSOHC,petrol-powered andFlexPower(powered withethanoland/or petrol, mixed in any percentage) engines. GM Brasil also made 16-valve versions of the 1.0 engine. The 1.0 L 16v was available in the Corsa line-up from 1999 to 2001.

1.2

There are two iterations of the 1.2-liter Family 1 engine. As originally introduced it was called the12ST(also A12ST and S12ST in versions for the Austrian, Swiss, and Swedish markets), it used a 77.8 mm (3.06 in) bore and a 62.9 mm (2.48 in) stroke to produce a displacement of 1,196 cc (73.0 cu in). This version, only carburetted, was used in theOpel Corsa.^[4]In around 1990 a new, version with 72.0 mm × 73.4 mm (2.83 in × 2.89 in) bore and stroke, a narrower bore version of the existing 1.3-litre version, displacing 1,195 cc (72.9 cu in), replaced the original design. This was also available with single-point fuel injection and with catalytic converters.

SPE / 4

TheSPE / 4or (Smart Performance Economy 4 cylinders) engines are an evolution of the Econo.Flex engines that were made in Brazil at theJoinvilleplant. There are two available displacements: 1.0 L and 1.4 L. They feature an SOHC head with 2-valves per cylinder, and is fed by amulti-point fuel injectionsystem, which allows it to run on either E100 (pureethanol) or E25 gasoline (standard in Brazil). Major differences between previous engines include reduced friction, lowered weight, individualcoil-near-plugignition, and a newcylinder headdesign.

Pre-Ecotec

This was the first engine in this family, featuring aLotus-developed 16-valvecylinder headand acast-iron cylinder blockwhich was essentially the same as in Opel's 8-valve engines. C16XE was available only inCorsa GSi,model years 1993 and 1994. C16XE was not yet badged Ecotec, and for later model Corsas andOpel Tigrasit was replaced with X16XE Ecotec engine. The main difference between C16XE and X16XE Ecotec isemission control,C16XE lacksEGRandAIR-system, although the cylinder head is designed to enable these features. Other differences between C16XE and later versions of the engine includeintake manifold,C16XE has a plastic upper intake manifold, which was replaced with a cast aluminium manifold, andfuel injectionsystem, C16XE uses Multec fuel injection withMAF sensorand later models used Multec fuel injection withMAP sensor.Also, while C16XE had its own exhaust front section design, for X16XE it was replaced with a front section used also in Opel Astra, probably as a cost-saving measure.

Daewoo Motorslicensed and produced a variant of theFamily 1engine. These engines were built exclusively at Bupyeong engine plant and marketed asE-TEC.Like allFamily 1engines they feature atoothed beltdriven valvetrain, a cast-ironengine blockand an aluminumcylinder head.Most models featureEuro III-compliancy, and the 1.4 L (1399 cc) and 1.6 L (1598cc) versions employvariable intakegeometry. With the release ofChevrolet Cruze,the factory has been converted to produce the Ecotec Family 1Gen IIIblock.

The newGeneration IIIorGen IIIengine entered production in Spring 2005. These engines replaced both the previous generationEcotecengines as well as Daewoo'sE-TEC 16Vengines. These engines are manufactured at Szentgotthárd, Hungary, Bupyeoung, Korea, Toluca, Mexico and Yantai, PRC (SGM).

In contrast to their predecessors, theGen IIIengines feature lighter cast-iron blocks, as well as higher compression ratios. These engines also implement DCVCP (Double Continuous Variable Cam Phasing technology, a variant ofVVT), piston cooling by oil jets, and an integratedcatalytic converter.Non-turbocharged variants feature theTwinPort(Variable-length intake manifold) technology. Reliability improvements include a wider camshaft drive belt, and a water pump no longer driven by it.

TheLDEengine meetsEuro VIandKULEVemission standards. With the addition ofsecondary air injectionto theLUWengine, theLWEachievesPZEVstatus.

These engines, like their DOHC predecessors, featurebucket tappetsin contrast to theroller finger followersfound on GM's other 4-cylinder engines.
