I was watching Eddie Stobart the other night,one of their trucks in particular was running on straight Liquefied Natural Gas/Bio Methane.The truck had a diesel engine.Anybody have this setup.

There are some Walsall buses running on CNG (Compressed natural gas) ..

There is a CNG filling station located close by to where I get my LPG from ..but I have only seen HGV in there ...

They said during the program that there where only 4 stations that could supply it, not sure when it was recorded but must have been in the last 2 years.

Where I work we made some ECUs for CNG converted diesels, I wasn't involved with them but I'm pretty sure that they ran spark plugs, I could ask a few questions when get back to work.

there.s a volvo artic on trade plates runing up and down the m6 most nights, fully frieghted at 44 tons, has all the natural gas tanks all over the back of the cab.
looks like it may be doing road testing. trailer all marked up natural gas.
it certainly goes well enough (no speed limiter fitted.)
dont fancy being around it though when it jacknifes.

LNG has to be transported and stored at -162°C, at that temperature its a liquid and is only at 3.6psi pressure, so provided it can be adequately insulated its fine - break the tank and you have a massive cloud of methane hanging over a crash scene - its highly explosive at that stage, and likely to cause asphyxiation as well !!

The diesel engines use the diesel to ignite the CNG/LNG, there have also been a number of petrol engines converted to run CNG or LNG.

I guess the problem would be the infrastructure, its reasonably popular in the emerging markets but they have are still building up their infrastructure. In this country petrol/diesel is well entrenched and the number of service stations is reducing so there isn't much incentive to build new stations for a different fuel.
