|
The Family II is a straight-4 piston engine that was originally developed by Adam Opel A.G. in late 1970s for use in the Opel Kadett D. Over time, the engine block has evolved to include many modern featurs such as DOHC and fuel injection. Many General Motors subsidaries, including Holden, GM do Brasil and recently GM Powertrain have adopted this design.

Ecotec
Ecotec name was adopted in 2000 for the new generation of Family II engines. The name was already used for Opel Family 1 and Family 0 range. GM intends for this new Ecotec to become its global 4-cylinder.
Ecotec Family II is a modern chain-driven DOHC 4-valve design with an aluminum block and head (L850), designed for displacements from 1.8 to 2.4 L. It was developed by an international team of engineers and technicians from Opel's International Technical Development Center in Rüsselsheim, Germany, GM Powertrain in Pontiac, Michigan, and Saab in Trollhättan, Sweden. The engine uses aluminum pistons and cast iron cylinder liners and vibration is reduced with twin balance shafts.
