I was talking about house gas there.

Interesting. |

| Hang on, are you saying that house gas is CNG? Or at least, CNG that is not very compressed? |

My AU S1 Tickford Duel Fuel starts on petrol momentarily but I keep about 1/4 tank of petrol in the car for emergencys.
Every 3 months or there abouts I run it on petrol (E10-95) and use 99% of the fuel and put $30 back in.
Other times it runs on LPG.
If I go on a trip I'll put in approx 1/2 tank just in case LPG stuffs up so I can make it to the next town. never had any probs yet.
wonder how many times taxi's switch to petrol....
and switching to petrol on shutdown will cause more engine wear as it washes the bores (petrol being liquid) why do you think LPG engines last longer???? |

House gas is natural gas, or methane, delivered at low pressure. To get a usable range from an NGV (natural gas vehicle), the gas needs to be stored in compressed state (200-250 bar maximum). The pressure is reduced at a regulator in a similar fashion to LPG. The only difference is that methane does not liquefy as readily as propane/butane (LPG) and therefore always remains in a gaseous state. LNG (liquefied natural gas) is natural gas stored at -161C in cryogenic tanks and is popular with line-haul truck as well as buses in the States.
Next time you ride a gas-powered bus, pay particular attention to the external roof-line. Chances are, a pack of high-pressure CNG gas cylinders will be hiding under a fibreglass cover towards the front of the bus.
