Japanese Government research into AdBlue in the UK

[japgov]

Hello all

I’m Paul Ellis, based in London, conducting research on behalf of the Japanese Ministry of Transport about how AdBlue and other SRC systems are used in the UK transport industry. The Japanese Government is considering introducing regulations similar to Euro 6. dieseldave has kindly allowed me to join this forum to carry out this research.

If you’d like to participate - and I’d be grateful if your would - I’ve pasted a short questionnaire below which should only take a few minutes to answer.

Please either reply here, or PM me. Just give me the question number, your answer, and any additional remarks.

The questionnaire is mostly to do with how drivers react to a low AdBlue warning. If this is not your responsibility and is always handled by Maintenance, please say so, and reply to the questions from that point of view. Names will not be passed on to the Japanese government or to any other body, and this research will not be used for any other purpose.

I’m on a fairly tight deadline: the research is due by the end of this week. If you’d like to know more about this, just ask. I’m happy to engage in discussion. Thank you, all.

Why drivers need know everything about ad blue.Same diesel drivers need just check level and go.If drivers have at least 1/2 of tank that this is enough for one shift definetily.

I’m an owner, not a driver, and the above is how things work at our place.

It’s part of the daily vehicle check. There is adblue stored in the warehouse and the vehicles carry a spare with them in case they need it/long journeys abroad. I’ve never been aware of anyone running out.

Driving 44years including non HGV

As per biggriffin, fill up when gauge gets to half, or whenever an adblu pump is next to diesel pump. Can go 3 or 4 weeks on a tankful, but carry a spare can just in case. Have never run low.

   Only due to a systems failure, sensor fault pump fault

Operators and manufacturers should be encouraged to fit large enough tanks to the vehicle, dependant on the vehicles intended or expected use. A vehicle doing return to base shift patterns may have a smaller tank, it could be topped up regularly at base. A vehicle spending multiple days away from base would be better suited to having a larger adblue tank, cutting the need for carrying spare drum of adblue

The answer to all the others is

I have a gauge which shows full or empty, I fill up the adblue when it gets to half a tank,

Simples

As above.
Some early adblue trucks had tanks that were too small. The current ones seem to have reserves enough for a week or two’s work. A gauge similar to a fuel gauge plus maybe a warning light when very low is good.

Thanks for the responses, everyone: they’ve been extremely useful. I hope the Ministry is not too surprised to discover that UK lorries have AdBlue gauges like fuel gauges; that drivers and operators top up AdBlue in a similar way to fuel; and that UK drivers use initiative and judgement when it comes to topping up whilst maintaining schedule, vehicle, and road safety, etc. I’ve hit my deadline now and submitted the research. Thanks once again, and thanks to your mods for allowing this thread.
