1.4-liter Opel A14NET or LUJ engine has been assembled since 2009 at the Wien-Aspern plant and is installed in a number of popular models of the company, such as Astra, Meriva, Mokka and Zafira. Now such units are gradually being replaced by modern Euro 6 engines of the new B-series.
The Opel 1.4 engine is the result of a new approach to civilian engine building. Small displacement engine with low pressure turbocharging (only 0.5 bar in the A14NET version). This ensures high fuel efficiency (reduces fuel consumption and increases engine power). Timing chain drive, hydraulic lifters are installed. There is a phase change system on both camshafts.
A10 family: A12XER, A14XER, A14NET, A16XER, A16LET, A16XHT, A18XER.
