Emissions & Safety


The Protection of the Environment Operations (Clean Air) Regulation 2002 - Clause 9 makes it an offence for any vehicle to emit visible exhaust smoke for a continuous period of more than 10 secondsÓ.
The single biggest emission difference you will notice is the reduction in black smoke under load.
Testing with a five-gas analyzer has shown reductions in other emissions and Diesel/Gas Australia are currently conducting full emissions testing and the results will be available soon. You can also contact us for further information on vehicles that have beeen approved.
So, unlike most other performance modifications, emissions are reduced. This is particularly important with the EPA targeting diesel vehicles.
Emissions aside, black smoke is unburnt fuel. If your vehicle is producing excessive black smoke this may mean it is not running as efficiently as it could be effecting economy and power. By using LPG as a catalyst near complete combustion occurs reducing black smoke and increasing efficiency.

Safety aspects

  1. Low Pressure In the event of a low GAS pressure (by accident or GAS loss) to the system, the solenoid on the gas tank shuts down, thus no GAS flow to the engine.
  2. Engine Temperature The GAS bending system will NOT operate until the engine temperature is at 40ˇ centigrade. (The GAS mapping will show fumigation however no GAS will be released).
  3. Low Voltage In the event of a drop of voltage, the system shuts down all gas flow; this is to prevent the unnecessary flow of unmeasured gas in to the engine.
  4. Idle Speed The system is set that at idle the injection of GAS is turned off.
  5. Braking Under braking conditions, by foot brake or exhaust brake, the system is set to shut off the injection of GAS.
