The Family 1 is a straight-4 piston engine that was developed by Opel, a subsidiary of General Motors to replace the Opel CIH engines for use on mid-range cars from Opel/Vauxhall. Originally produced at the Aspern engine plant, production was moved to the Szentgotthard engine plant in Hungary[2] with the introduction of the DOHC version. GM do Brasil at São José dos Campos,[3] GMDAT at Bupyeong and GM North America at Toluca also build these engines.
The Family 1 engines are inline-4 cylinder engines with an belt-driven aluminum cylinder head with a cast iron engine block. GM do Brasil versions were also capable of running on ethanol. These engines are sometimes referred to as "Small-block" engines by enthusiasts; in contrast to the larger Family II engines which are sometimes referred to as the "Big-block" engines.
GM do Brasil specializes in 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.[WIKI] |
