Some of us might recall an article I posted a few months ago about Volkswagon releasing a mobile phone app that listens to their engines and transmissions and diagnoses problems with better than 90% accuracy – Well, shit just got real, because now we can ‘see’ sound in real time.

Acoustic imaging, or the ability to see ultrasonic sound, has emerged as an effective method for manufacturing and utility organizations to locate compressed air leaks or the existence of partial discharge (PD). It enables professionals to conduct more frequent predictive maintenance routines, helping provide a crucial first warning of impending electrical/mechanical failure that could lead to energy loss and even worse, downtime of critical systems.

Excellent. I’ve wanted that for a long time, and even got to the stage of designing a prototype device to do it. (Buying some of the raw materials but never assembling it).

Just a few days I saw on TV that the US Navy already has it. The nose domes of their latest class of submarines contains a device to passively ‘see’ sound around all 360 degrees in real time.

But the US Nave device is impossibly big and expensive. Something smaller, particularly for car sounds, really is needed.

The makers of this one claim to be able to detect air/gas leaks and electrical arcing in noisy industrial environments, which is going to be a step-change improvement for industry.

Got a link to that please? I’m dubious.

You don’t reckon the German car manufacturing group who spent $US14.3Bil on R&D last year could make a mobile phone recognise big end noise?

Not when $US14.2999999999B was spent fudging emission testing.

Seems pejorative.

Nup, just speaking the truth.

One firmware tweak, to one engine, ten years ago.

Not dissimilar to what they’ve all been doing for decades. Before software tweaks, there was a Japanese motorcycle manufacturer that had a fix for noise regulations. There was a very specific test that meant giving it full throttle at a specific rpm and measuring the noise as the bike accelerated past the noise meter. The bike had a resonating part in the exhaust that gave it a flat spot at that rpm so it went slower through the test. That part usually fell out during the first service.

11 million cars. Move on…nothing to see here.

Sibeen’s right to be pissed off about this one. It’s estimated the extra NOX has contributed to 5,000 deaths.

I know about this because I’m currently driving the engine in question. The firmware fix made no measurable difference to it – It’s still producing 125kW and 350NM and averaging 5.3L/100km well within emission regs. and there’s every chance it will keep doing that for a million Ks. Maybe two million.

Make of that what ye will.

And back to the money…As of 1 June 2020, the scandal had cost VW $33.3 billion in fines, penalties, financial settlements and buyback costs. Oh fucking dear.

Not enough? Too much? How does one gauge? Should we be billing everyone who unknowingly contributes to the early deaths of a few thousand people?

Ta for that – I had a read and it’s specific to some Skode engine types – That does make sense – there’s far too many variables to make it work well for all engine types.

Skodas are full VAG running gear, so the app should work for the brands that share engines (Skoda, Volks, Audi, Seat) but probably not Porsche, Lambo, Bentleigh, Ducati etc yet.
