V-Power Diesel | Posts 48+

So, if when buying a TDI, a pack of 10 Mass Air Flow sensors and turbochargers were included without extra cost, packaged like tablets (for easy removal).

I never had any problems with any of these parts throughout the entire lifespan of my car (up to 200,000 km).

So, to reiterate: What do you think about my LMM replacement (see above)? I mean, wouldn't the pressure and temperature sensors last forever, or what?

Millions of gas stations do it this way...

Engine speed, throttle position, intake manifold pressure (if available). Fine-tuning via oxygen sensor.

Are you sure the SDI doesn't have a mass airflow sensor?

'By the way, pressure and temperature sensors last just as long as everything else... so they're just as likely to fail unexpectedly, like when you need to use the toilet.'

By the way, my LMM is from ITT and it's a 1N4007. It works great and saves fuel (for some reason).

CU Gremlin.

I've built a fake mass airflow sensor (MAF) for the LMM using an AVR microcontroller. It calculates the approximate air mass based on engine speed and boost pressure. So far, it works reasonably well. However, it occasionally becomes unstable (likely due to issues with the RPM measurement), resulting in a zero air mass reading. The engine control unit (ECU) then interprets this as a fault condition and triggers a limp-home mode with approximately 500mg/stroke. To improve accuracy and obtain a more precise air mass value, one would need to incorporate the intake air temperature into the calculation.
But otherwise, I agree with Gremlin. The other sensors are similarly susceptible to interference as the mass airflow sensor (MAF).

Starting July 1st, Shell is introducing the new V-Power Diesel, which is supposed to be 'more responsive,' with a cetane number of 56 instead of 51. Additives are intended to prevent deposits on modern injectors. The price is 4 cents higher than conventional diesel. What do you think about it?

Regards.

Hi there,

To get back to the topic...

In our newspaper, it was reported that the new fuel is mostly (the percentage wasn't specified) produced synthetically from natural gas.
I suspect there are two reasons for this:
1. Developing an 'alternative' to crude oil.
2. Providing an even purer fuel for a cleaner combustion process.

It's possible that this new fuel will behave the same way as regular gasoline. Over time, there will be more and more cars optimized for this type of fuel, just like all new gasoline-powered cars are now designed to run on premium gasoline only. In many European countries, regular gasoline is no longer available. Let's wait a few years and see what happens. Then it will likely be the same with diesel.VW once said that we still need better fuels to make engines cleaner and more fuel-efficient. Now, there's the fuel for that, and the engines designed to use it will be available soon. They will probably also work with older diesel engines, but then they will produce more emissions and have less power, just like a gasoline engine designed for premium fuel being run on regular.
Greetings.

Eike.

It might work with the new fuel just like it does with regular gasoline.

Hm, if that were the case, I would switch to a different brand of gasoline. That's why the new 3.5-liter V6 from Mercedes-Benz happily runs on regular gasoline, while its competitors all require premium... If everything was optimized for V-Power, I would fill up at the private airfield. Aviation fuel has 110 octane....if you're going to do it, then do it right!

There's something to that...

If you think about it:

'In the past, 55 kW of power came from an engine displacement of 1.6 liters.'
Today, you can get 66 kW from an engine with a displacement of 1.6 liters, and even 55 kW or even 74 kW from an engine with a displacement of 1.4 liters.

'The engines have a higher compression ratio and require fuel with a higher octane rating, as well as operating at higher RPMs.'

First, they lure the customer in with lower taxes (based on engine displacement), then with ultimate new technology.

Basically, these toy engines don't actually use less fuel because you have to rev them up quite high. And the 16-valve technology adds its own problems. The maximum power is at 4000 RPM... that's laughable.

The end of the story: I have to pay more money, at best for the same amount of fuel, because my car needs 'premium' gasoline instead of regular. What's the point of that?

And no one can tell me that those few octane (or cetane) numbers cost significantly more to produce.

CU Gremlin.

Diesel engines are increasingly reducing compression ratios .

That's a completely different game, I know...

m;

Mazola is willing enough .

However, diesel engines are increasingly reducing their compression ratio .

That's a completely different game, I know...


'Man, people are getting so soft these days... back in the day, my ex-girlfriend had an '88 Golf 2... those 54 horsepower were really noticeable in every situation, the engine was fantastic! The only downside was that the cold morning starting ritual wasn't exactly appreciated by the neighbors... but it still sounded like a diesel, which I can't quite say about my own car anymore (question from an uninformed passenger: 'Is that a quiet 1.8T...? Or maybe a 2.4?') *grumble*.'

@Julian

The 88mm gun was already a soft target! It actually had hydrostatic pressure vessels.

My 4/85 was even better; it always sounded about 20 km/h faster than my '87, because the valve lifters were making a lot of noise.

Yes, yes, those were the days .

Okay, please provide the German text you would like me to translate into English. I will only provide the translation.

And the fuel consumption of these older diesel models was even better, even with a 4-speed gearbox.
My girlfriend's (now wife's) car used to consistently get under 5 liters per 100 kilometers.

Impossible with my current setup (see below). And it was also very compact; it weighed almost nothing.

Best regards, D.

@ D.

Okay, I also got my JP with an engine size under 5 liters (but it had a 5-speed transmission).

The "Pampersbomber" aims to stay above 5.2 meters thanks to its weight of 1400 kilograms.

The AFN G3 variants are significantly more fuel-efficient (I've heard of colleagues getting under 4.5 liters per 100 kilometers – but then they were driving very gently on the highway).

@SeatArosa1.7SDI

Regarding your signature:

1Z - the robust turbo.
- Enjoy a leisurely cruise - yes.
- Power - yes.
- a new LMM every year - no thanks.
- No thanks, I'm not dealing with turbo troubles.
- Engine failure after 100,000 km - no thanks.
- Damn timing belt - unfortunately, yes.
- Possible issues with the ESP system - unfortunately, yes.

Otherwise, the car has 174,000 km on the odometer, it's the first turbo engine, the first injectors (but they are almost worn out), and the first ESP system.

Best regards, WarLord.

I completely agree with WarLord.

At 237,000 km, the first set of injectors, the first mass airflow sensor (MAF), and the first electronic stability program (ESP) were replaced; only the second catalytic converter was installed, and now the third timing belt is needed.

Hey everyone, before people start bragging about their running distances again...

So, and now what?

Best regards, WarLord.

Okay, so I've now stood at the gas station pump several times, and each time, V-Power Diesel has been available. (And I really love collecting those points! )

Today, I only wanted to fill up with 20 euros worth of diesel because it's €1.97 per liter!
However, the jet fuel right next to it cost 100.9 per liter!

Now, the boss just came by and asked me if I had already tested the new diesel.

No, why would I, it's so expensive and probably doesn't do anything!

But his acquaintances have only had good experiences, etc... (finally someone who doesn't just read from that shell information booklet!).

Are you going to pay me the difference compared to regular diesel?

They can just flip a coin to decide it!

Okay, so I filled up with 50 liters of gas, keeping in mind that the bill might be 4 euros higher than expected.

But she wasn't!
Shell charged me the difference of 8 cents per liter, which equals 4 euros in cash.
Also, I have 250 Shell points instead of 50.
You get a KitKat Chunky for 19 points! *delicious* *lol*

This weekend, I'll be doing the long-distance test.
Full throttle on the highway, just like every weekend when I'm out and about...

See you next week!
Daniel.
