Available in a wide range of cubic capacities ranging from 1598 to 2405cc, it simultaneously replaced the Opel OHV, Opel CIH and Vauxhall Slant-4 engines, and was GM Europe's core powerplant design for much of the 1980s. The engine features a cast iron block, an aluminum head, and a timing belt driven valvetrain. The timing belt also drives the water pump. It was first used in the Opel Kadett D, Ascona B, Corsa and their corresponding Vauxhall sister models, the Astra, Cavalier and Nova. Many General Motors subsidiaries, including Daewoo, GM do Brasil, GM Powertrain, and Holden have used this design. By 1986, the Family II unit had completely supplanted the CIH engine as Opel's core 4-cylinder powerplant. although the 6-cylinder versions of the CIH continued in the larger Omega and Senator models until 1995. In 2004, a 2.0 L ''MultiPower'' engine was made available for the taxi market which could use gasoline, alcohol and natural gas. The ''Family II'' also spawned two diesel variants, the 1.6 L and 1.7 L. These engines are sometimes referred to as "Big-block" engines by enthusiasts; in contrast to the smaller Family 1 engines which are sometimes referred to as the "Small-block" engines. The development track of these engines split in 1987, with the introduction of the 20XE; which featured a 16-valve DOHC head. Although SOHC versions are still in production in Brazil, most DOHC engines were replaced by the all-aluminum GM Ecotec engine family. Holden made various Family II engines for Opel, GM Daewoo, GM India, and Isuzu at its Port Melbourne plant. Variations include displacements from 1.8 L to 2.4 L. Unlike the Ecotec engines, the block is made of iron. ==SOHC== | bore = | stroke = | compression = | fuelsystem = | management = | power = | specpower = | torque = | length = | width = | height = | weight = }} These engines formed the basis of the modern Family II lineup. Configuration was limited to a single over head cam, and 2 Valves per cylinder (8 valves total). The 20NE served as the base, where later Family II engines evolved. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「GM Family II engine」の詳細全文を読む スポンサード リンク
