The first generation Ecotec engines are belt-driven 16-valve DOHC engines, with cast-iron cylinder blocks and aluminum cross-flow cylinder heads.
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. Other differences between C16XE and later versions of the engine include intake manifold, C16XE has a plastic upper intake manifold, which was replaced with a cast aluminium manifold, and fuel injection system, C16XE uses Multec fuel injection with MAF sensor and later models used Multec fuel injection with MAP sensor. The main difference between C16XE and X16XE Ecotec is emission control, C16XE lacks EGR and AIR-system, although the cylinder head is designed to enable these features. C16XE was not yet badged Ecotec, and for later model Corsas and Opel Tigras it was replaced with X16XE Ecotec engine. C16XE was available only in Corsa GSi, model years 19. This was the first engine in this family, featuring a Lotus-developed 16-valve cylinder head and a cast-iron cylinder block which was essentially the same as in Opel's 8-valve engines. = Displacement (in tenths of liters)Ĭ = Three-way catalytic converter, Euro 1 The 1.0 L 16v was available in the Corsa line-up from 1999 to 2001.Ģ./3. GM Brasil also made 16-valve versions of the 1.0 engine. GM do Brasil specializes in SOHC, petrol-powered and FlexPower (powered with ethanol and/or petrol, mixed in any percentage) engines. 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 versions were also capable of running on ethanol.
The Family 1 engines are inline-four cylinder engines with belt-driven single or double overhead camshafts in an aluminum cylinder head with a cast iron engine block.
