The Opel Vauxhall X18XE Engine range
From 1998 on
Vauxhall Opel X18XE1
The X18XE1 is a gasoline engine from Opel , which was produced from 1998. The engine has a displacement of 1.8 liters (1796 cm³) with a stroke of 88.2 mm and a bore of 80.5 mm. It has 16 valves and delivers 85 kW (116 hp) at 5400 rpm. The maximum torque is 170 Nm at 3400 rpm. This was installed among others in the Astra G and Vectra B .
It is the successor of the X18XE , which was made from the "BigBlock" engine block for the larger 2.0 liter engines . Due to constantly occurring cracks in the manifold this was was scrapped. The X18XE1 is cast from the same engine block as the 1.6-liter engines and has only larger holes in the cylinders . This belongs to the Ecotec engine series, has hydraulic tappets as valve train and can easily with LPG / LPG operate. Frequent problems with the X18XE1 include idle speed fluctuations due to dirty throttle valves (combustion residues from exhaust gas recirculation ). The successor to the X18XE1 is the Z18XE .
Vauxhall Opel Z18XE
Z18XE is the engine code of the car manufacturer Opel developed and manufactured gasoline engine . This is the successor to the X18XE1 and has, like its predecessor, the following technical data:
- four cylinders
- 1796 cc displacement (stroke × bore 88.2 mm × 80.5 mm)
- 16 valves
- two overhead camshafts ( driven by a toothed belt)
- Exhaust gas recirculation valve
Unlike the X18XE1, however, it has an output of 92 kW (125 hp) at 5600 rpm in the Astra ,Zafira and Vectra of 85 kW (116 hp) , and 90 kW (122 hp) in the Vectra C. given at 6000 / min and a maximum torque of 167 Nm at 3800 / min. this also complies with the emission standards Euro 3 and D4, in Vectra C Euro 4 was achieved. With the Corsa C GSi / Sport built Opel for the first time the Z18XE in a small car, which makes 92 kW (125 hp). The Corsa C GSi / Sport remains thus as the largest motorized engine in the Corsa series.
The Simtec MS71 engine management system works on the principle of ME-Motronic, a combined ignition and injection system with electronic throttle control (e-gas). The Z18XE has a variable intake manifold . The air mass drawn in by the engine is detected by a hot-film air mass meter between the air filter and intake manifold . The high-voltage generation for the sparks is realized by the fully electronic ignition system via an integrated ignition module with one ignition coil for each cylinder.
Significant constructive differences to the X18XE1 are:
- E-gas (electrically operated throttle , instead of cable)
- two lambda probes , instead of just one (a control probe in front of the catalytic converter , a monitor probe behind the catalytic converter)
- Motor control : Simtec MS71 instead of MS70 (manufacturer Siemens VDO )
Successor of the Z18XE is the newly constructed Z18XER with camshaft adjustment, which is built since September 2005. It delivers 103 kW (140 hp) at 6300 rpm.

The engine was used in the models Astra H , Meriva , Signum , Vectra C , Zafira B and Fiat Croma .
Despite this additional equipment, it was possible to reduce the weight of the new engine by three percent compared to its predecessor, while at the same time achieving greater rigidity .
