Let's discuss diesel...

[burnz]

regen,, you burn a fine particle (soot) into another type of fine particle (ash)
but ash will pass threw eventually, so how long does it last,, like a cat converter if it never gets overheated 15+yrs..
then suddenly collapse,, buy such time the wreakers would be full of them.

I don't mean to seem rude but you didn't answer the question. What sort of involvement with dpf-related stuff do you have that you can base your comments from? What are your skills/experience/expertise that tells you the life of a DPF is from 15+ years to limitless?

I'm just asking for you to back up what you're saying because anyone can say anything on a forum, it's nothing personal.

Ever heard of a conversation ??? These forums demanding to keep on topic, kill it. One thing leads to another, that's life.

Nothing wrong with getting sidetracked a bit, but the capabilities of Australia's Collins submarines have nothing to do with the subject, but could make an interesting topic on the Bar.

If you want a conversation, start a conversation thread.

As far as this thread is concerned it's about diesel.

This comes to mind.

'cause THEY WERE NOT ON TOPIC

The question was why is the raptor going petrol and not diesel. If you ask me they are on topic, and if they weren't the thread would only be 2 posts long. What other replies would you suggest to such a simple question ????

mechanical engineer by trade.. worked with cummins, Detroit diesel, electromotive drive, VM motori, saab, merc benz,, all diesel, oddly haven't worked with caterpillar or volvo..

PS: the life of a DPF is entirely up you the consumer!!

Bugger me - I think there's a planet out there somewhere that's missing an inhabitant...

If you think in a few years time semis wont be banned from congested cities, and there cargo wont be dropped of out of town then reloaded onto greener vans.(which is exactly what I said will happen) Then don't get on a horse, just go get some drugs that may help your thankers and your delusions.

that may happen, but expect to pay double for your food, fuel and greens..

dear me. if you really believe this will happen in australia, then you really do need stronger meds or a better shrink.

define 'a few years'??

do some simple research and maths regarding the amount of tonnage carried by diesel transport, and then work out how many 'greener' vans will be required to distribute this throughout the areas that are currently serviced by diesel haulage.

its fine to be an idealist. but idealists and reality are generally poles apart.

Tesla trucks. Problem solved

[dunga]

They will just ban trucks that wont meet the latest euro standards .

I would suggest you stop arguing. You turn every thread you post in into a combat zone. Learn how to do it or go back to Whirlpool.

I never mentioned Australia I only said congested cities. I predict it will happen in Melbourne and Sydney in 15 years. For the most congested cities in the world I think its already happening, if not London, Tokyo, LA, Rio, Rome and about 50 cities in China and Asia its only 2 years off.

Maybe steam will make a comeback as a mainstream power source?

Yes, they will be electric. Another reason they will be banned, is there's not enough room in the city's for these mammoth 18 wheelers.

Just read whole thread, phew.

For my 2c the most interesting engine development seems to be going on at Mazda - the Skyactiv-X seems to be somewhere between a petrol and diesel engine. It should run on 91, has a compression up near the diesel, and can burn petrol in a compression phase at times.

A dedicated ethanol engine will also feature this higher compression and efficiency.

So what we might get (in passenger cars) is the petrol and diesel morphing into one.

Also I've noticed Tojo teaming Atkinson cycle motors with its hybrid drive - can anyone explain why these motors are a better choice? Toyota are making (some of, one of?) their DI motors have a separate injector behind the valves so these dont suffer the extreme carbonation that small turbo petrols have in recent years.

Lastly, no one mentioned gassing monkeys in a diesel thread. Think of the monkeys

The idea us using an "Atkinson" cycle motor is to gain more energy per amount of fuel burned compared to the typical 4 cycle/Otto cycle engine.

This is not the same thing as "make more power".

In the mid-late 1800s James Atkinson came up with a linked connection between what would ordinarily be called a connecting rod and crankshaft.

What this intermediate linking allowed to happen was for all 4 cycles on an internal combustion reciprocating engine to happen in 1 revolution of the crankshaft instead of 2. I have never analyzed one of these so I can not say where the inherent efficiencies are in doing this.

Now let's talk a little bit about what is being called an "Atkinson" cycle engine these days. Anyone dismantling one of Toyota's "Atkinson" cycle engines will be disappointed if they are expecting to see this linked arrangement. It is not there.

What will be found is an engine (I believe in Toyota's case) claimed to be Atkinson is an arrangement the intake valves are held open a significantly longer period of time than usual. This pushes some of the fresh intake charge back into the intake track, which does 2 things from a fuel efficiency standpoint.

1. There is a reduction of pumping losses; power lost to running the internal pump, which an IC engine is.

2. The intake charged push back into the intake track contains residual spent contaminants remaining from the previous combustion. A built in EGR which primarily helps with how fuel is burned in daily driving applications.

For a technical break down of EGR principles I would have to defer to Peter (yearby).

Both methods listed above, original Atkinson cycle and today's "Atkinson" cycle, result in an overall less powerful engine, yet produce more power for amount of fuel consumed.

Unless someone can point me in another direction, what today is called an "Atkinson" cycle engine if really a Miller cycle engine. I know some may have been taught or told contrary, but Ralph Miller patented 2 Miller cycle designs.

One of these principles is at the heart of what Toyota and the world journos call an Atkinson cycle.

The other reduces cylinder pumping losses by closing the intake valve way early prior to the piston reaching bottom dead center (BDC) during the intake cycle. The cylinder never fills up, so it is easier to compress during the compression cycle. It doesn't do anything with EGR.

Again resulting in less total power, yet more power per the amount of fuel consumed.

trouble is if you do the sums ...most trucks carry around 30 ton payload it would take a really big van to carry 2 ton ....and thats fifteen vans to do the work of 1 truck

take a look how many trucks there are supplying the goods to a city then x15 ....it would be van grid-lock everywhere you went + 15x skilled operators for the vans or otherwise the poor cyclists would be skittled at every intersection

[Vesper Martini]

I don't think Greenies comprehend economics.

Ban this! get rid of That! Protest protest, but they never come up with a Practical viable solution

The same sort of idiot logic was stuffed down our throats here by council. They reconfigured the bin route to reduce usage of the garbage truck and save the environment. So now we have 100s of residents towing bins behind their utes 1-2km each instead of one truck doing the rounds. Net effect is a lot more fuel burnt. Its pretty clear what the real motive was though.

Steam turbines powered by nuclear fission are still pretty mainstream.

[roKWiz]

Yes, the load of frozen fish has been dropped at our outer depot and is currently being reloaded into our fleet of smaller greener vehicles for your convenience.

Yes they are now to make that package smaller and safer to be used in other things besides power generation would be the challenge.
