GM Family 0 engine

Reciprocating internal combustion engine

The Family 0 is a family of inline piston engines that was developed by Opel, at the time a subsidiary of General Motors, as a low-displacement engine for use on entry-level subcompact cars from Opel/Vauxhall.

Quick Facts Family 0, Overview ...

These engines feature a light-weight cast-iron semi-closed deck engine block with an aluminum cylinder head. The valvetrain consists of chain-driven hollowcast dual overhead camshafts (DOHC) that actuate 4-valves per cylinder via roller finger followers with hydraulic tappets. These engines also feature a 78 mm (3.1 in) bore spacing and fracture-split connecting rods.

Later versions also incorporate a variable length intake manifold (VLIM) and variable valve timing (VVT).

Originally debuting as either a 1.0 L (973 cc) straight-3 or 1.2 L (1,199 cc) straight-4; a 1.4 L (1,364 cc) I4 variant was added with the introduction of the second generation, replacing the 1.4 L Family 1 engine. The Family 0 engines were produced by Opel Wien in Vienna/Aspern (Austria), by GM in Bupyeong (Korea) and Flint (Michigan, USA).

Generation III

The EcoFlex engine is a version of the TwinPort tuned to provide better fuel economy and lower emissions. The 1.4 L engine was introduced in 2008 and the 1.0 L engine in 2010. For model year 2012, the EcoFlex engines have been updated with double cam phasing (DCVCP) in a Gen III block.

Certain Opel and US-market Chevrolet versions of the Delta II platform compact cars use a turbocharged version of the 1.4 L engine with double variable cam phasing (DCVCP); in the future, an optional gasoline direct injection system will be introduced.^[1] Opel versions feature Start&Stop system from 2011 and a Gen III block; a lower-power 120 ps version has been introduced as well. For model year 2013, the overboost to 220 N⋅m (162 lb⋅ft) has been added.^[2]
