    Mazda BT-50 2011: LPG, CNG, or LNG?

    Mazda Mazda Advice Mazda BT-50 Mazda BT-50 Advice Mazda BT-50 2011
    Warren Clark (Carsguide 19/08/11) does not state which gas he is going to use in his diesel BT-50. Is it CNG, LNG or LPG? I understand that some city buses run on CNG, and I have read that Wesfarmers have converted their West Australian truck fleet to dual-fuel system, but are using LNG. If Warren is proposing to use LPG the fuel charge will have to be well managed since the LPG is a more energy dense charge. It would be a very interesting article if you could report on the results of companies using this fuel format of distillate and gas.

    There are a number of heavy trucks running dual-fuel systems with a blend of diesel and natural gas, on some the gas is compressed (CNG) and on others it's liquefied (LNG). There are also other heavy truck systems that use diesel and LPG. We have reported on all of them over the past couple of years. In the case of light commercial vehicles the systems employed use diesel and LPG, substituting LPG for diesel, and as you say it needs to be very carefully controlled. The more LPG you use the more power you will get, but if it's not well controlled you run the risk of damaging the engine and that's very costly.
