How it works

Safety

The Autogas LPG or CNG system has a number of important safety features including:

 

A 3mm welded steel pressure cylinder which is stress-tested to many times its normal operating pressure prior to being installed;

 

Two electronically controlled shut-off solenoids (on autogas LPG tank and on reducer under bonnet) which stop the flow of LPG autogas to the engine if the engine stops for any reason)

 

Pressure relief valves for the tank and the system, to prevent any pressure build up that may damage the system, or be hazardous;
Double back-check valves to ensure autogas tight filling; Sealed compartments and venting around valves and pipe-work to ensure no LPG enters the interior of the vehicle;

 

Approved components to ensure long service life.

Safety of Autogas Overfill

Autogas tanks are designed with an Automatic Fill Limiter (AFL) to prevent overfilling so the release of excess fuel during the refueling process is virtually eliminated. 

 

On the other hand, most of us have experienced petrol spills. Also, unlike spilled petrol, which will puddle under your car, any LPG that might escape just dissipates into the air.

Pressure Relief Valves

Autogas tanks are designed to withstand even the most extreme conditions.

 

The tanks are designed with 20% unused volume to allow for any expansion of the LPG in hot conditions. 

 

There is also a pressure relief valve that ensures that the internal tank pressure stays within safe tolerances, even when the tank may be exposed to an abnormal amount of heat.
