    The GM Family I is a

    piston engine that was developed by Opel, a former subsidiary of General Motors and now a subsidiary of PSA Group, to replace the Vauxhall OHV, Opel OHV and the smaller capacity Opel CIH engines for use on small to mid-range cars from Opel/Vauxhall. The engine first appeared in the Opel Kadett D in 1979, and shortly afterwards in its Vauxhall badged sister – the Vauxhall Astra Mk.1
    in 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 larger Family II unit (correspondingly known as the "large block"), which covers the mid range and higher engine capacities up to 2400cc.

    Originally produced at the

    GMDAT at Bupyeong and GM North America at Toluca also build these engines. The Family II units, by contrast were manufactured by Holden
    in Australia.

    Design

    The Family 1 engines are inline-four cylinder engines with belt-driven single or double overhead camshafts in an aluminum

    Family II
    engine – 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.

    SOHC, petrol-powered and FlexPower (powered with ethanol
    and/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 the 12ST (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 the Opel 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

    The SPE / 4 or (Smart Performance Economy 4 cylinders) engines are an evolution of the Econo.Flex engines that were made in Brazil at the Joinville plant. 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 a

    coil-near-plug ignition, and a new cylinder head
    design.

    . 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.

    The new Generation III or Gen III engine entered production in Spring 2005. These engines replaced both the previous generation Ecotec engines as well as Daewoo's E-TEC 16V engines. These engines are manufactured at Szentgotthárd, Hungary, Bupyeoung, Korea, Toluca, Mexico and Yantai, PRC (SGM).

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

    The LDE engine meets

    PZEV
    status.

    These engines, like their DOHC predecessors, feature

    roller finger followers
    found on GM's other 4-cylinder engines.
