Chronology

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.

Contents

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. Currently, the Family 0 engines are produced by Opel Wien in Vienna/Aspern (Austria), by GM in Bupyeong (Korea) and Flint (Michigan, USA).

Generation I

The engine was first introduced in 1996 Opel Corsa, either as a three-cylinder or as a four-cylinder version. This was Opel's first three-cylinder engine.

Generation II

The second generation Family 0 began production in November 2002. It is an updated version of the Family 0 engine and features TwinPort technology – twin intake ports with a choke closing one of the ports at low RPM, providing strong air swirl pattern for higher torque levels and better fuel economy. The crankshaft and oil galleries were also redesigned to lower power loss; thereby increasing fuel economy.

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]

Opel also adds the marketing term "Whisper Diesel" in some markets, claiming relatively low levels of noise, vibration, and harshness. Production commenced in late 2013 at Szentgotthárd, Hungary. The MDE is Opel's first all-aluminum diesel engine and offers a power density of 85 hp (63 kW) per liter 136 PS in its most powerful version. Maximum power and torque have been increased versus the previous-generation 1.7-liter engine, while fuel consumption has been reduced by up to 10 percent compared with a 2.0-liter CDTI engine of similar power output. This new 1.6 CDTI engine will replace the current 1.7-liter and lower-powered 2.0-liter diesel engines in a wide range of Opel models, with more- and less-powerful versions to come. The most powerful version of this engine, delivering 136 PS at 3,500–4,000 rpm and 320 N⋅m (236 lb⋅ft) at 2,000 rpm, was first introduced in the 2013 Opel Zafira Tourer, and later in the 2014 Opel Astra J and restyled 2014 Opel Meriva B. In 2014, versions were released with power outputs of 110 and 95 PS.
