The '''[[Ecotec]]''' name was adopted in 2000 for the new generation of Family II engines. The name was already used for the Opel GM Family II engine, [[GM Family 1 engine|Family 1]] and [[GM Family 0 engine|Family 0]] ranges. GM intends this new Ecotec to become its global 4-cylinder. | The '''[[Ecotec]]''' name was adopted in 2000 for the new generation of Family II engines.

The Ecotec Family II is a [[DOHC]] [[multivalve|4-valve]] design with an aluminum block and head (L850 for 86 mm bore applications, and L880 for 88 mm bore), 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 Automobile|Saab]] in [[Trollhättan]], [[Sweden]]. | The Ecotec Family II is a [[DOHC]] [[multivalve|4-valve]] design with an aluminum block and head (L850 for 86 mm bore applications, and L880 for 88 mm bore), designed for displacements from 1.8 to 2.4 L.

Much of the development work on this project was carried out by [http://www.grouplotus.com/eng/ Lotus Engineering], Hethel, [[United Kingdom]]. The engine uses [[aluminum]] pistons and cast [[iron]] cylinder liners. Vibration is reduced with twin [[balance shaft]]s. | ||
