Cheating car emission tests

[Coligny]

Or i take the Delica off the roads and use it only as a power generator, 110kw minus efficiency of whatever is driven...

Wouldn't something designed as a generator from scratch be far more compact, efficient and economical?

And 110kw minus efficiency? That's quite an alternator you have in the Delica. This little unit is a mere 3.2 kw so 30 times less.

110kw is the flywheel power output

Yep at 5,000 rpm or so?

Masses of power but if you need a couple of Kw for recharging batteries and keeping the lights and rice cooker on then surely a little generator with it's own little engine is the way to go?

Not that I have one mind - just speculating.

Joking ?
It's 109kw at 3500rpm, i redline at 4000rpm

Long time since I've owned a diesel. So out of curiosity cos I love these things. How then to transmit 110Kw at the flywheel @ 3,500 rpm to a generator capable of doing it some justice? And what about engine cooling? And fuel consumption?

If it was to be done road legality aside:

Power take off on the left of the output shaft using a steel belt (from a dead cvt gearbox) on a bolted hub. There is an access behind the bottom gravel shield to allow the accessory belt replacement. It bypass the torque converter and the road gearbox on the right.
After that you're free to use any alternator.

Cooling is not an issue, 1 diesel run hot, 2 the cooling radiator is oversized and troublesome in cold weather. Use too much heater for the passenger and the engine is not able to reach the regular temperature of 90° but instead struggle between 75 and 80.

Emperor Willhelm II was so right, when he said "I believe in the horse, the automobile is no more than a transitory phenomenon".

Guess I'd better spend the rest of the Sunday on YouTube to learn how to ride a horse. I am sure, I will need that skill sooner or later.

It is very easy to concentrate urea. For guys, anyway. Just take your common PET bottle and piss in it but leave the cap off. Do this daily in your shop, car, truck – wherever. The water will slowly evaporate, and the urea will stay – with the solution increasing in opaqueness day by day. At the end of a month, you should be ready to go. Recap and shake – to break up the urea crystals. Use it in your VW, or pour it at the base of a tree you want to die `naturally` so that it can be removed without upsetting its owner.

Whoever told you that was spouting bullshit. Although, to be fair, if the nail is big enough to ringbark the tree it might work.

I have done it with copper brads - just over 2cm long spaced about 5mm apart. On thick bark trees, the nails would need to be a bit longer.

[wagyl]

And this is quicker, both in commission of the crime and in time to death, than ringbarking? Which works really good, to use the terms employed by whoever spouted bullshit to Coligny.

Copper nails take longer - the snow has melted, the grass has grown, and even the bark has covered the small heads of the brads, so no evidence remains. The tap tap tap of the hammer is almost unheard.

OK. Enjoy continuing to kill trees you have no right to then. Even if you are killing them by trauma rather than by micronutrients, and at greater expense to you.

Back on topic, I came across some interesting comments:

The emissions test detector system is a standard feature of all modern cars. In the age of computer-controlled traction control and ABS, the car isn't programmed to cope with inputs that roughly translate as "my forward wheels are doing revs for 50mph but my back wheels are stationary and the intake manifold pressure is nowhere near where it should be at 50mph, WTF is going on?!" In that scenario, cars start doing all manner of amusingly unpredictable things which screw with the test results.

Hence VW, and everyone else, has a test detector mode built into the ECU, the engine's electronic brain. This is supposed to work by telling it, "You're on a test rig, just roll with it (see what we did there?) and behave normally." Instead, VW quietly tweaked the test mode.

As [that comment] observes, all cars have to have some code to handle the engine when it's being tested ... and this code has to handle abnormal inputs so has to be different to the "normal" driving code.

So next you need to write the code to be used during testing. You can make the engine do just about anything that physics allows, so do you write code that fails the emissions test, or do you write code that passes the test?

It's not that hard to see how you end up where VW is.

http://www.theregister.co.uk/2015/09/26 ... d_mirrors/

Where this starts to go into the realm of unconscionable, is the allegation that a hidden reservoir of AdBlue is activated during that test mode. And to tell the truth, the benefit for VW of that is that they can advertise that, unlike the competition, their vehicles do not need additive to be pumped into the exhaust system (a very small victory, and a lie to boot) with the downside that their vehicles pump out NOx like its 1950. As the article states, this is a result of our hard-on for greenhouse gases.

Wait until someone does the calculations on added methane excretion from the increased horse stable.

Surely going forward, the testing agency should supply the ECU test mode program specifications and review the code for compliance….

Why would anyone want to kill trees?

Not kill trees - but rather, kill a specific tree... for visibility, because of droppings, for spite, for added sunlight, etc.

At present, on the south side of my garden space I have a grove of towering trees on `banchi nashi` land - land that is not registered by anyone and does not show up in any official records. I care for it, but everyone in the neighborhood knows it isn`t mine so keeps an eye out. A stink would arise if I just cut the massive trees to obtain sunlight, but not if I am cutting down dead and thus dangerous trees. I could attempt to obtain agreement, but then it wouldn`t be official, and for sure an octogenarian would claim - `but I climbed that tree when I was only 10`.

VW scandal: Company warned over test cheating years ago

EFF: DMCA Hinders Exposing More Software Cheats Like Volkswagen's
from the you-bet-it-does dept.
ideonexus writes:
Automakers have argued that the 1998 Digital Millennium Copyright Act makes it unlawful for researchers to review the code controlling their vehicles without the manufacturer's permission, making it extremely difficult to expose software cheats like the one Volkswagen used to fake emissions tests. Arguing that this obfuscation of code goes so far as to endanger lives at times, the Electronic Frontier Foundation (EFF) maintains that, "When you entrust your health, safety, or privacy to a device, the law shouldn't punish you for trying to understand how that device works and whether it is trustworthy."

Could become intredasting... Thanks Gunthar...

Use too much heater for the passenger and the engine is not able to reach the regular temperature of 90° but instead struggle between 75 and 80.

That's a problem on many small-engined cars. I don't know how this is dealt with on the hybrids.

If the outside temperature is too cold and the inside too balmy, the engine won't drop below fast idle speed. You can imagine what this does to fuel consumption.

[Coligny]

When i was a kitten in cold countries they gave you a plate to put in front of the radiator to reduce the cooling efficiency.
Then there was the Renault Alpine A310 4 cylinders who could reach 200kph on the highway in summer 1974 with a coolant temp falling to 70°...

I'd be surprised if Mitsubishi was not caught by harbles on this scandal...

Japan’s Mitsubishi Motors finds falsified fuel mileage tests

Mitsubishi Motors Corp., the Japanese automaker tarnished by a massive recall-cover-up 15 years ago, owned up to another scandal Wednesday, saying employees had intentionally falsified fuel mileage test data for several vehicle models.

The inaccurate tests by the Tokyo-based automaker involved 157,000 of its own-brand eK wagon and eK Space light passenger cars, and 468,000 Dayz and Dayz Roox vehicles produced for Nissan Motor Co.

The models are all so-called “minicars” with tiny engines whose main attraction is generally great mileage. They were produced from March 2013.

The problem surfaced after Nissan pointed out inconsistencies in data, the company said. Mitsubishi conducted an internal probe and found that tire pressure data was falsified to make mileage appear better than it actually was.

“The wrongdoing was intentional. It is clear the falsification was done to make the mileage look better. But why they would resort to fraud to do this is still unclear,” company president Tetsuro Aikawa told reporters.

He and other company executives bowed in apology.

Aikawa said that although he was unaware the irregularities were happening, “I feel responsible.”

The company said it would investigate whether data were altered for vehicles sold overseas. It was unclear by how much the data were altered.

Mitsubishi Motors struggled for years to win back consumer trust after an auto defects scandal in the early 2000s over cover-ups of problems such as failing brakes, faulty clutches and fuel tanks prone to falling off dating back to the 1970s.

Aikawa was asked if the latest impropriety highlighted how the company had not fundamentally fixed itself after the recall scandal, although it had promised repeatedly to come clean.

“I realize that view exists,” he said, his voice shaking slightly. “I see how difficult it can be to have compliance consciousness spread among all our employees.”

Mitsubishi, which also makes the Outlander sport-utility vehicle and the i-MiEV electric car, is setting up a panel of outsiders to investigate the latest scandal.

“We will investigate why this happened and prevent a recurrence,” said Aikawa. “We will inform our customers. I feel horrible they were given the wrong numbers.”

Production and sales for all affected models were halted, according to the companies.

Nissan said in a statement that it recently discovered discrepancies in data from Mitsubishi about light vehicles it provided while assessing the current model in preparation for its next-generation vehicle.

“In response to Nissan’s request, Mitsubishi admitted that data had been intentionally manipulated in its fuel economy testing process for certification,” Nissan said.

It said that after consulting Japan’s transport ministry, it told dealers to stop selling the affected vehicles. Nissan was considering ways to help owners of the cars already sold.

“Nissan understands and regrets the inconvenience and concern this will cause our valued customers,” it said.

Japan has been hit periodically by such scandals at top-name companies. Among the recent ones are electronics company Toshiba Corp., which acknowledged it had doctored accounting books for years.

Unlike some Western accounting scandals, the ones in Japan did not result in enrichment of individual employees. Instead, workers simply wanted to “save face” for the company.

I don't either, though I must say I got plenty of mileage from my past Mitsubishi Minica...

Anyway, my Honda StpWgn's mileage is not much worse than the specs in the sales brochures. Of course, it also depends on my driving style, but I am able to exceed the official specs if I drive around 70 km/h on the highway. Key is keeping the RPM below 2500.
