Glyc (again).

[Oilybloke]

These people http://www.aquafuelresearch.com/ claim to be running a 40KWh Deutz engine on glyc. I'm just reading through the bumph now, and trying to understand how (& why) it works.

Any thoughts?

Oily.

It burns with so little energy... must require special engine technology!

I'm always a little suspicious when a University discovers exactly the kind of world changing technology that suits their private company sponsors.
I can't actually find anything to say that Greenwich Uni is being sponsored by Aquafuel research, so may be they are not.

This kind of suggests that the Glyc is heated, and they use a lot of it.

"As for the ‘stickiness’ that makes it so useful for cough medicines, this drops dramatically with temperature and at 90°C its viscosity is about 13cSt – the same as that of fuel oil.

Many marine engines could be able to handle adaptation: this would include of course glycerine fuel piping and delivery; while some modification is required for a glycerine start, standard injectors can be used and there’s no need for glow plugs or heating of the tanks. There’s also some necessity for the automation of fuel and air valves, but Mr McNeil says that if the vessel is well equipped with up-to-date technology, this doesn’t actually need too much modification."

I visited a Tyne dock once when they were working a tanker and had a look around it

it was a tar tanker, with giant heated tanks, and burnt tar to provide heat to the tanks... but once it was nice and hot the engine ran on the tar too (or maybe it was just a mix of it ? it was a long time ago....)


I've no idea what tar is like to burn in an engine... but I'm guessing it's harder to burn than glyc ?

Heavy fuel oil as used by large marine engines has to be kept at at least 70c just to move it.

It has the consistency of bitumen, the fuel consumption is measured in tons per hour.

Where's the reckless engineer when we want him. He makes his living fuelling huge marine diesel engines and would no doubt give us all the data in the world about their fuels.

As ships get bigger, the pollution is getting worse. The most staggering statistic of all is that just 16 of the world’s largest ships can produce as much lung-clogging sulphur pollution as all the world’s cars.

That is truly a scary thought. I can see why the motorists get clobbered for green taxes...easy option for most governments...but come on, Mr Cameron, easy option number 2 here.

Ah ye' but when you break it down to MPG/ton it's over 1000miles per gallon per ton, and compared to power generation it's just a drop in the ocean.

iirc polution from cars amounts to approx. 2% of total CO2 output, you need to get things in prospective.

[julesandtash]

Exactly....
Locomotives and ships may have, what on the face of it, appears to be horrendous fuel consumption but, when worked out in tonne miles per gallon (or tonne) of fuel, is actually very economical.
