You comparing it to Diesel is the crap.Diesel is much cleaner.
well I guess I made my point

Sorry for being so gruff.

Perhaps similar to diesel particles are laser printer toner particles.

A recent Australian study will have you thinking twice about waiting for those printouts — not for the sake of the paper, but for your health. In the small study, published in the Aug. 1 issue of Environmental Science and Technology, researchers found that nearly 30% of the 62 printers they tested — including laser printers from Canon, HP, Toshiba and Ricoh — emitted high levels of ultrafine toner particles, which were potentially as hazardous as cigarette smoke. In one Brisbane office, the authors found, the concentration of particulate matter per square inch was five times higher during working hours than nonworking hours, and about 3.5 times higher inside than outside, where a freeway ran 130 yards from the building.

For the new study, Lidia Morawska, a physicist at the Queensland Institute of Technology, and her colleagues analyzed printer emissions in a large open-plan office environment. The good news was that 60% of the printers they tested, including eight HP LaserJet 4050 models, four Ricoh Aficio models and one Toshiba Studio, did not emit any particles. But of the 40% that did, many, such as the HP LaserJet 1320 and 4250 models, were classified as "high-level emitters." Emissions, researchers found, were printer-specific and fluctuated depending on the age of the toner cartridge and the amount of toner a document required. It was unclear exactly what mechanism dispersed the particles into the air, but researchers think it had to do with how laser-printer cartridges access and use dry toner or with the printer's mechanical abrasion, wear and age. It's likely that different printers emit particles in different ways.

HP says, in a statement, that it disagrees with the conclusion of the study and with some of its stronger assertions — and believes there is no link between printer emissions and a public health risk. The study's authors concede that more research is needed before they can make any recommendations about the public's printer-related behavior. This study, says Charles Weschler, a chemist and indoor air pollution expert at the Robert Wood Johnson Medical School, is "very much a first cut."

Though it may be premature to inaugurate the term "office lung," the new study highlights the fact that indoor air pollution can't be taken lightly. "It's important to appreciate that most of the air we breathe — whether in our homes, our cars or our offices — is indoors," says Weschler. The Environmental Protection Agency estimates that 90% of our time is spent indoors. According to Weschler, indoor pollution either seeps in from outside (such as particulate matter from car exhaust, ground-level ozone and noxious gases, like sulfur dioxide, which comes from fuel combustion and factories) or originates inside (tobacco smoke, cooking gas, vapors from paint). In general, concentrations of volatile organic compounds, like cleaning agents and pesticides, can sometimes be 10 times higher indoors than outdoors, says Weschler. With long-term exposure, these types of air pollutants can be linked to allergies and respiratory illness, or worse.

The EPA has not done any recent research on the health effects of printer emissions — Morawska's study is the most extensive to date — but Sharon Worthy of the U.S. Dept. of Labor says "historically laser printers have presented no known hazard in the workplace." But, according to the Washington-based nonprofit Environmental Working Group, which has conducted research on particulate pollution from automobiles, printers release the same type of fine particles that cars do. "What we need are standards up front so that the pollution we're subjected to don't pose health risks," says Jane Houlihan, the nonprofit's vice president for research. "Printers are just one of the many things we're exposed to during the day that are potentially harmful."

There is an additive I know of though that can help clean up the emissions of the older type engines and it also reduces fuel consumption.
As an example, a diesel train using it to go across the Bight to Perth & back would normally use about 88,000 litres, with the product (okay, I'm part of a group that's trying to sell it) the train proved that the consumption went down to about 77,000 litres and the emissions were over 10% improved.

Let me guess, it's called Firepower and you are working with Tim Johnson on it?

From the 4 Corners program on Firepower:

ASSOCIATE PROFESSOR DAMON HONNERY, MONASH UNIVERSITY: All I can say is that I've tested lots of additives and I found no significant, no improvement at all. Now we can test to within about one-and-a-half per cent, that's our accuracy of testing, which is quite reasonable and none of the additives that we've tested have got any better than one-and-a-half per cent.

LIZ JACKSON (to Damon Honnery): I'll ask you just about a couple of specific claims. I mean what about a fuel saving claim of 27 per cent with an emission reduction of 45 per cent?

ASSOCIATE PROFESSOR DAMON HONNERY, MONASH UNIVERSITY: Well you'd have to wonder what they were doing before they (laughs), before they used the, before they used the additive.

We're getting into the realms almost of fantasy here. There are fundamental laws governing engines and diesel engines particular which is the engine that we test, are already highly, highly efficient engines and to get that sort of improvement would be extraordinary.

Nope.

Bugger, I was hoping that you would give us a clue.

I can't yet sorry.
But yes this stuff really does work and rather well.

The only additive that will give you 10% more kilometreage from a diesel engine is adding 10% more diesel.

Rev, LPG diesel conversions do give you more power/economy for the amount of diesel used. I feel that LNG is also a fuel for the future here in WA. There are many trucking companies that are using it. If the price of diesel goes up these will take off. Diesel LNG conversions with a 50/50 mix are also available for a cheaper installation cost.

OK, maybe what I said was a bit sweeping. Obviously if you replace some of the diesel with a higher energy fuel, or one that can be used more efficiently, you can get more energy out.

[DariushPetresku]

Gas leaks are usually innoccuous until it's too late, H/air ratios for ignition are quite wide, and the ignition is EXPLOSIVE. LPG/LNG: I'm told a gas cigarette lighter is about equal to one stick of gelignite in energy [perhaps under ideal conditions?]. In event of collision, compressed gases leak rather easily, and present a real risk to the remaining occupants and any rescuers. Why do you think gas powered vehicles have that red tag on their numberplates? It's a warning label!!!! Petrol is risky too, I'll admit, but petrol leaks are a little easier to prevent, and diesel is safer still, being more difficult to ignite. I am amazed at the level of gullibility in the Oz military which allowed them to be associated with Firepower-an obvious fraud to any decently educated mechanically minded person. >100yrs of motorcycle engine/fuel development has pretty well covered the field without such radical success==be very suspicious, indeed, assume fraud from the beginning. Bit like that other innane idea, putting a turbulator into an inlet manifold-can only work on the very poorest quality induction systems, and then only marginally. Ever seen any on a racing engine??? Why not??

That's what I was thinking when I posted that segment about Firepower.

I think Bill has been sucked in by some Tim Johnson/Firepower clone.

(Obviously this doesn't apply to LPG/Diesel mixes where you are replacing some Diesel with LPG.)

No Bill hasn't.
I've seen the test results and it works as advertised.
We're going to be chasing the government for a grant to do more formalised testing though so we can give the various companies more accurate figures over a wide variety of conditions.

Effect of a homogeneous combustion catalyst on the combustion characteristics and fuel efficiency in a diesel engine

Mingming Zhu,
Yu Ma,
Dongke Zhang

► A ferrous-picrate catalyst has been shown to improve diesel engine efficiency.
► The fuel consumption is reduced by up to 4.2% with the use of the catalyst.
► The catalyst shortens ignition delay and combustion duration.

I once worked on formulating a cerium dioxide nanoparticle additive for diesel fuel. It was aimed at reducing emissions, with cities in Asia as the main market. That was more than a decade ago and I see that the concept has been under research ever since, by bodies like the US EPA. I have lost touch with the topic now.
