Nothing like looking at a CNG vehicle. Here are a few pictures of the Opel CNG Zafira with turbocharged engine, long range with 4 carbon fiber tanks. The tank contains natural gas with a pressure of 2,900 psi.
The tanks have a valve block with several safety functions. An electromagnetic valve will normally be closed when:
- The ignition is switched to “OFF” position.
- The engine is switched off or running on gasoline.
- SRS components are activated. A shut-off valve is located at the valve block and can be closed manually.
- A pressure relief device (PRD) is intended to release gas from the tank in
The Opel Zafira CNG is available in Germany, it should also be available in Italy sometimes next year. You may find it in the US as a Buick? The Buick Regal started life as the Opel Insignia, and the Buick Verano is originally an Opel Astra, so it could be.
