Have you ever wondered why diesel car sales experienced a boom in Europe but nowhere else in the world?
To answer this we must begin way back in 1973, with the first oil crisis which occurred the Organization of Arab Petroleum Exporting Countries or OPEC initiated a total oil embargo. The result was a shock and dramatic shortage of crude oil that caused the price of a barrel of oil and derived products to increase by 300% shortly after the embargo was put into place.
The problem with the European oil processing industry in the years after the 1973 oil crisis was that they no longer had buyers for their heavy distillates because the energy generation and heating systems of Europe had transitioned to other sources.
But oil refineries weren’t the only ones impacted by the oil crisis. Vehicle manufacturers also suffered because the dramatic increase in fuel prices lead to a dramatic decrease in car sales.
So manufacturers sought to offer buyers more fuel efficient alternatives in the form of vehicles with diesel engines which are naturally more fuel efficient than their gasoline counterparts. The main reasons behind this being that diesel engines naturally operate at noticeably higher compression ratios, they don’t need a homogenous air fuel mixture and don’t require a throttle body to function which means that they can run at very lean air fuel ratios and don’t suffer from pumping losses.
Faced with reduced taxation, improved fuel economy and better performance and driveability in the real world many buyers started started switching to diesel engined cars. If we look at the data it becomes obvious how dieselisation was never a matter of user preference or different tastes in Europe and the US or other countries. If we compare Japan and Europe we can observe very similar low rates of diesel share in the market. The markets only start diverging when European legislation started strongly favoring diesels and creating incentives for buyers. If we observe Europe on a country by country basis we can see that diesel adoption is highest in countries like France for example where legislation and taxation was very favourabnle for diesels.
But initially it appeared thst the mass dieselisation of the vehicle market was a win for everyone in Europe. Oil refineries got a market for their products. Consumers got better cars. Car makers got profits. C02 emissions got reduced. Almost sounds too good to be true. .Well pretty soon it became clear that it indeed all was too good to be true because as time moved on and emissions standards became more stringent it became evident that getting diesel engines to meet new emissions standards was far harder than it was originally envisaged by the Auto Oil 1 and 2 programmes.
And so Manufacturers started reducing the compression ratio of diesel engines to reduce nitrogen oxide emissions. Which sort of defeats the purpose of a diesel engine because reducing the compression ratio also reduced efficiency and power output. To restore power manufacturers increased the boost pressure from the turbocharger which lead to increased C02 emissions which ultimately resulted in equivalent diesel and petrol engines having pretty much the same power output and the same C02 emissions.
But in 2015 it became evident just how far manufacturers were stretching the truth when it was discovered that VW had to cheat to meet US emissions tests. They reprogrammed their diesel vehicles to be able to detect when they are undergoing emissions testing and then run the engine in a reduced performance mode in order to generate reduced emissions and pass the test. When not being tested and driven in normal conditions the vehicles were actually emitting 14 times more nitrogen oxides then the allowable US limit and 3 times more than the Euro 5 emissions standard.

@21:15 "hybrid" is not a fuel type, it's a propulsion type. Some hybrids use diesel, some use gasoline.
Such an impressive video with absolutely wonderful presentation. I doff my cap to you sir.
NOx pollution is maybe 100x less than in 70s, and we survived. Pollution limits and supposed "premature deaths" are just a scam to kill cars.
Many more reasons to remain skeptical..?
Eg the actual inverted-reverse image of "the rise of the right" continues to obliterate standards for quality of life.
EVs are definitely better than either diesel or petrol cars. there is no question about it. Don't let past mistakes of government cloud this simple truth.
this sounds very similar to how EV's are promoted as environmentally friendly & subsidized in the US, despite the reality of the increased toxic emissions created by battery manufacturing and running the coal power plants to charge them.
I'd be skeptical of the data about diesel engines . I doubt diesel engines are the cause of smog . Europeans are densely populated and the "scientists" that did the data research were given an outcome to arrive at; and the data "magical" lends itself to using a different method of fueling transportation. Europeans are brainwashed cucks when it comes to listening to the government ; no insult intended. I don't know why you people put up with the government.
12:20 This seems a bit misleading. The NOx limit is higher for diesels, but both the CO limit and HC limit is lower for diesels. In 2001, 2.3g/km CO for petrol and 0.66g/km for diesels. Neither of these gases have strong greenhouse impact. CO2 limits, the main greenhouse gas, are same for both engines as far as I can tell. Also, petrol engines are exempt from PM (particulate matter) limits altogether, while diesels have set limits. The legislative limits don't seem to particularly favor diesels in this case, they're just adjusted for various technical aspects of both engines.
Id argue that Diesel enginges did in fact lower carbon emissions. Diesel cars from that era consume at least 30% less fuel (in liters) compared to petrol cars and diesel releases only about 12% more CO2 per liter.
The guy holding this presentation do not know much about all the different kinds of crude oils that exist and how to refine them to modern fuels, e.g. high octane petrol, high cetane diesel fuel with low content of sulphur and aromatic hydrocarbons (HC:s). He does not seem to know about alternative and more climate smart liquid fuels produced from other energy rich feedstocks than fossile crude oils. Crops and agricultural waste, forestry biproduct e.g. unwanted tree species, branches, tops, bark, black liquor from Pulp industry, etc. can be converted to liquid fuels by industrial chemical processes. Then Hydrogen gas (H2) is needed. H2 can be produced from water by large scale electrolysis. Climate smart electricity for the electrolysis can come from wind power, solar PV:s, water power, etc. Also waste that is now deposited or incinerated without using so much of the energy in waste, could be processed to liquid fuels instead.
Have you heard this so called ”fact”? An electric car (EV) cannot have any emissions. An EV doesn’t even have an exhaust pipe. An EV is due to the heavy battery a heavier car than e.g. a diesel car. The friction between the tyres and the asphalt (with small stones / gravel inside the asphalt) makes many small particles consisting of toxic substances e.g. asphaltenes, rubber dust, dust from the gravel… EV produces in fact more toxic fine particles (PM10 and even smaller particles) than cars with combustion engines do… This is science and facts instead of politics… You may talk about particle in air specialists at e.g. research institute VTI in Linköping, Sweden. There must be many research groups in EU and USA doing research on air quality and fine / ultrafine particles in air, including the sources of these particles.
If you tuned, a diesel, it produced more smoke, which is more poke, e.g BHP!!!
There is no reason there are still cars with a petrol engine new for sale.
With the clean, efficient and refined diesel engines available today, diesels are just the better choice.
And after all, almost every mobile vehicle from the somewhat larger lawn mower to the largest ocean liner is running on a diesel engine, except air planes for good reasons.
Great video. Even in Latin America some started to think that the future was diesel in small cars.
Some time ago I stumbled upon Speed of Air pistons. And I think they are in collaboration with Total Seal piston rings. Dave's Auto Center has a few videos about the matter.
Of course it feels a bit "promo-oriented", but I think their solution could be one of the saving graces of diesel engines in general.
As I have multiple diesel engines at my possession, I would really like to do some testing. As I probably couldn't get a total seal rings for my applications, I'd try to get the top of the piston dimpled and ceramic coated and then add RVS treatment to the engine and see what happens. But of course the dimple part should include quite a lot of science and flow simulation in order to work in an optimal manner. Though I'd guess if the dimples are "just working", no matter how they are placed they should at least have some effect in reducing the stagnant air layer that causes unburnt diesel to exit the combustion chamber, raising the exhaust temp and causing all kinds of nastiness.
Plastic bags saves the trees
Plastics the devil
Growing your own food is great and healthy
Growing your own is a dogwhistle you’re an extremist
Diesels best
Diesels like literally the devil
Petrols better than diesel so clean
Petrols so awful omg get electric cars
Electric cars are unviable, more expensive and putting too much strain on the grid never mind the child mining omg
Basically the worlds governments are all flipfloppers that don’t really know what they’re doing
Another fantastically insightful video. A real eye opener. Thank you 👍🇬🇧
Guvment doing what the guvment does best… Giving benefits to people to buy the most current thing because it's "eco friendly" and then years later they "accidentally" discover that it actually wasn't very good for the environment and remove all benefits, making your purchase entirely unnecessary. This happened with diesel and ethanol in Sweden. And I bet my a** that they're doing the exact same thing with EVs. They're going to "discover" that the battery packs are toxic in a few years. And eventually renewable energy charging will be taxed just like all other fuels.
It would seem that most of your narrative is based on the paper you cite at 20mins 43secs. I have read the paper and as an academic author myself I always pay great attention to who pays the Piper to sing the tune they want to hear, and low and behold guess who paid this Piper…..the "Financial support was provided by the Federal Ministry of Education and Research of Germany (BMBF)" (A Government backed organisation). Couple this with the extensive list of references from some, allegedly, anti diesel and environmental zealots, with funding ranging from the "U.S. Environmental Protection Agency", "International Council on Clean Transportation (ICCT)", "National Renewable Energy Laboratory"…….to name just a few. This would seem to me to put your opinions and content in the "biased" column. It would be helpful to this listener if you gathered your information from multiple sources and from those who have no dog in the fight.
Until now, the government and politicians think about only in their own stomach.
It´s a great clowning, and they want to making us clowns!
The EU is mostly held together by lie propaganda! I wouldn't put my faith in the privately funded WHO either! Their reports are garbage!You're making awesome content, man! They're by far professional than the 99% of the motor journalists!
It’s time to shut the EPA down.
3:48 That plant you filmed is in my hometown, Oporto, Portugal! It's the now deactivated Refinaria de Matosinhos ! Cool!
they create problems, and the solution is always the same: more power and resources for them
The efficiency of diesel engines is a good reason, terrible engines though. Strong with emissions and noise. Good torque.
The same concept is now being apllied for electric cars
When a small group of people, government bureaucrats for example, makes rules and forces a large group of people to comply… there will be unintended consequences. Usually, whatever the bureaucrats are trying to accomplish will get worse and other unintended consequences will result in economic hardship for the people, at best, and you can add sickness and death for the people in most cases.
A great example of this that has likely impacted every human being on the earth is the government decision to add lead to gasoline. Millions of people have died as a result and almost everyone on earth now has a lower IQ than they otherwise would have.
When consumers and manufacturers look at millions of ideas about what is best for their particular situation, we collectively see the results of many plans and are able to pick the best from among them. When one government agency forces one solution on everyone, they may have ignored a thousand better ideas.
And, in another decade, we'll realise that CO2 is actually environmentally beneficial.
Low power output == best emission , but people don’t want that. Governments and people cook up any legislation that favors the latest hype and profit. Electric has just as much if not more problems than petrol. Research why covering the Sahara with solar panels doesn’t work
sound a lot like an electrical vehicles story from 2060
thanks for deleting my answer…
and this one is about to be too…
regards
Be happy
Thx alot, great video that explain everything!
But Diesel Engines make such a cool sound…
The government was lying then,just as they are lying now.
oh boy .. you are sooo naive thinking that this time the powerbrokers have citizens in mind. the misguided netzero ideology is going to bankrupt all of europe.
Great Explanation!! Totally understand very interesting and informative 👏💯
It's like ideologically determined goals clash with reality and rarely lead to something good.
USA gonna become diesel soon as well
Diesel is the best
We have some new sick diesel tech. Diesel electric is the way to go as the engine can be run smoothly and effectively on the motorway while the batter can take over during city driving. Automated and semi automated driving could also help.
WHO figures mean nothing. look at COVID
Absolutely no lessons learned by government's and do not look for that kind of intelligent decision. All governments practice knee jerk responses, a lot is kickbacks later after someone has completed the political term hence they are dead or living were they cannot get extridated.
One of the best eye-opening videos I’ve ever been lucky enough to see. As usual everything dishonest and devious flowing like a poisoned river coming from governments. Sadly the forced drive for electric with its massively falsified 'Green Credentials' and utterly unworkable infrastructure for the majority is another disaster.
What is the full name of the video? YouTube app doesn’t let me see it
Only one thing do I consider: Does Diesel save me money? Yes, it does.
Ordinary Toyota gas engines are now as high compression as common diesel cars ever were.
It stupid to give up on diesel
It stupid to adopt full electric
Just as stupid to go for hybrid
Plug in hybrid..
Ofcourse if you dont have a concious mind you'l pick these stupid alternatives
Tis idealistic to hope european governments have learn anything from the diesel-story of yours : they listen nobody but lobbyists and money. If any conflict occurs between general interest and THEIR interests, they always choose their's. They have given up their own responsabilities towards the folk. They just try to save appearences and know their rich friends who own the press will never talk about the real deals of our time. So thanks " driving for answer" to talk turkey. Keep it on
