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

The engine features light cast-iron engine block, aluminum cylinder head with Hollowcast camshafts and DOHC valvetrains driven by chain. Modern versions use variable intake length and VVT.

First generation

The engine was first introduced in 1996 Opel Corsa as a 3-cylinder version.

  • X10XE'1.0 L' Straight-3 (973 cc): 40 kW / 55 hp, 82 N⋅m (60 lb⋅ft) @ 2800 rpm ( Corsa B )
  • Z10XE'1.0 L' Straight-3 (973 cc): 43 kW / 58 hp, 85 N⋅m (63 lb⋅ft) ( Corsa C )
  • X12XE'1.2 L' Straight-3 (1199 cc): 72.5 mm (2.85  in) bore, 72.6 mm (2.86 in) stroke, 10.1:1 compression, 65 hp (48 kW) @ 5600 rpm, 110 N⋅m (81 lb⋅ft) @ 4000 rpm ( Corsa B )
  • Z12XE'1.2 L' Straight-4 (1199 cc): 72.5 mm (2.85  in) bore, 72.6 mm (2.86 in) stroke, 10.1:1 compression, 75 hp (55 kW) @ 5600 rpm, 110 N⋅m (81 lb⋅ft) @ 4000 rpm ( Corsa C )

TwinPort

New, updated version of the engine, introduced in 2003. 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.

  • Z10XEP 1.0 L Straight-3 (998 cc): 73.4 mm (2.89  in) bore, 78.6 mm (2.94 in) stroke, 10.5:1 compression, 60 hp (44 kW) @ 5600 rpm, 65 lbs.ft (88 Nm) @ 3800 rpm.
  • Z12XEP 1.2 L Straight-4 (1229 cc): 73.4 mm (2.89  in) bore, 72.6 mm (2.86 in) stroke, 10.5:1 compression, 80 hp (59 kW) @ 5600 rpm, 81 lbs.ft (110 Nm) @ 4000 rpm.
  • Z14XEP 1.4 L Straight-4 (1389 cc): 73.4 mm (2.89  in) bore, 80.6 mm (3.2 in) stroke, 10.5:1 compression, 90 hp (66 kW) @ 5600 rpm, 92 lbs.ft (125 Nm) @ 4000 rpm.

For model year 2011, the Ecotec Twinport 1.2 and 1.4 engines have been updated with double cam phasing.

Ecotec TwinPort engines are used in:

EcoFLEX

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 1.0 L engine in 2010.

  • 1.0 L Straight-3 (998 cc): 73.4 mm (2.89  in) bore, 78.6 mm (2.94 in) stroke, 10.5:1 compression, 64 hp (48 kW) @ 5300 rpm, 66 lbs.ft (90 Nm) @ 4000 rpm.
  • 1.4 L Straight-4 (1398 cc): 73.4 mm (2.89  in) bore, 82.6 mm (3.3 in) stroke, 10.5:1 compression, 130 N⋅m (96 lb⋅ft) @ 4000 rpm, 87 hp (65 kW) @ 5600 rpm or 100 hp (75 kW) @ 6000 rpm

The EcoFlex engine is used in:

Turbo

Opel and US-market Chevrolet versions of the Delta II platform compact cars use a turbocharged version of the 1.4 L engine with of variable valve timing; in the future, an optional gasoline direct injection system will be introduced.[1][2] This small turbocharged engine will deliver the performance of much larger naturally aspirated engines while maintaining fuel efficiency of a small engine. EPA estimated highway fuel economy is 42 mpg.[3] Opel versions feature Start&Stop system from 2011; a lower-power 120 ps version has been introduced as well.

  • A14NET: 1.4 L Straight-4 (1364 cc): 72.5 mm (2.85 in) bore, 82.6 mm (3.3 in) stroke, 9.5:1 compression, 140 PS (103.0 kW; 138.1 hp) @ 4900-6000 rpm, 200 N⋅m (150 lb⋅ft) @ 1850-4900 rpm.
  • A14NEL: 1.4 L Straight-4 (1364 cc): 72.5 mm (2.85 in) bore, 82.6 mm (3.3 in) stroke, 9.5:1 compression, 120 PS (88.3 kW; 118.4 hp) @ 4200 rpm, 200 N⋅m (150 lb⋅ft) @ 1850-4900 rpm.

The engine is used in:

HCCI

The direct injection version of 1.4 L VVT Turbo engine will be able to operate in ignition-less HCCI (Homogeneous Charge Compression Ignition) mode [4][5] when equipped with two-step adjustable valve lift with variable cam phasing and advanced ECU with cylinder pressure sensors. 6.8–8 km/litre (16-19 mpg) in the city(over 800 km). 9–12 km/litre (21-28 mpg) on the highway (over 800 km) [in which vehicle?].
