Why Is Diesel Used to Fuel Heavy Machines and Vehicles?

[@Andrew-y1r1h]

Diesel is also more difficult to set on fire, which makes it less likely to explode if fuel or vapour leaks. This makes it much safer, especially in marine applications where gasoline vapours can get trapped in a boat’s hull.

[@Mojave9370]

Everyone talks about the price of gas while the cost of diesel is what affects the price of stuff.

[@mikeoneil5741]

if diesel is less refined than gasoline, why is it more expensive? it used to be cheaper.

[@ScottStClair-dm6vk]

supply and demand !

[@Darknamja]

Because the general public started to buy more diesel-powered vehicles, including mine, corporations saw the chance to make more money. 🤨

[@droobsterse7153]

You can get much more gasoline from a barrel of crude oil than diesel, so diesel is considered a “rarer” commodity

[@scoty7392]

Government intervention

[@kenta6591]

Demand supply balance

[@test143000]

Rudolf Diesel didn't event diesel fuel, he invented a diesel engine which can run on multiple types of heavy fuels, diesel is just one of them.

[@EdMcF1]

Diesel isn't 'less refined' so much as a denser fraction of the distillate of crude oil, so it is a bit heavier and the benefits of that are that it is less flammable and has more energy per weight. It also freezes at a higher temperature than gasoline (petrol), which is a negative in the higher latitudes, but which can be overcome with additives or fuel heating.

[@rjj479]

The modern diesel cars are such a pleasure to drive and so economical

[@stephenm3667]

It was nice to listen to an informative video that directly answers the headline question and doesn’t go back to the book of genesis to take the long way around

[@terenceiutzi4003]

It used to be 1/4 the price of gas. Now, no one has the technology to build large high torque gas engines like they did in the 50s and 60s. Cummins is working on one that looks promising. In Panama, they are still using the big V 12 GMC busses from the 50s! They run them on E95 because we no longer have high octain gas.

[@jonathanjones3126]

Diesel electric trains are awesome, diesel generator combined with electric motors

[@MrDebranjandutta]

In India diesel used to be half as expensive as petrol (gas), since it was subsidized. As a result manufacturers inteoduced diesels to power every class of vehicles incl. subcompacts. The govt realised this was a problem, and soon the price parity was brought down, along with stringent emission norms. On the flip side that increased price inflation since the heavy transportation sectors heavily depends on diesel, but now fewer manufacturers are now offering diesels for passenger cars, especially after dieselgate

[@Br4ido]

emission control is slowing killing the diesel industry

[@laliths945]

Compression Ratio of a Gasoline (Petrol) Engine is between 8:1 & 12:1 while for Diesel Engines it is typically 14:1 - 22:1. As a result, Diesel Engines are more fuel efficient.

[@kryts27]

In a nutshell; diesel engines have torque and efficiency (over gasoline or petrol engines). The bore stroke of a diesel engine is over-square (meaning it's a further stroke than the cylinder head), wheras petrol is typically under-square. Petrol engines are better at high revolution engines; like piston aero-engines and sports cars, having more speed but less torque. Diesel better for load bearing machines like trucks. The pressure in a diesel engine cylinder is at least 6 times higher than petrol engines, and the engine generally is more robust although petrol engines are lighter. The high pressure explodes the oily diesel fuel and air mix in the cylinder, wheras the lower pressure petrol engines need ignition by spark plug.

[@bobschultz2895]

Because of the higher compression ratio the more you decompress the air after ignition the more power you get. The exhaust will come out cooler, more energy extracted.

[@rob5944]

I've noticed that the latest engines in cars and light vans seem very smooth and quiet, although I gather diesels are heavier than petrol/gasoline engines?

[@Cotronixco]

Another advantage to diesel over gasoline is that diesel is less combustible and causes fewer fire-related accidents.

[@kennethosuji720]

The video is very insightful, direct and clear explanation which makes it easier to understand.

[@formerfarmer1718]

Simple. It comes down to the difference of BTUs. Diesel has more BTUs than gasoline. More BTUs, more rapidly expanding air in the combustion chamber which moves pistons.

[@josephgaviota]

Very Interesting. One thing I don't understand. If diesel has more energy than gasoline, and is particularly good at moving heavy loads, why is it, when driving uphill on the highways, the cars are zipping along at 70, and the trucks are in the slow lane going 25 mpg. I completely respect diesel engines, I'm just trying to understand "if it has more power, why does it go slower."

[@Howoldareweanywayyipes]

They sold many diesel cars because the diesel is cheaper... they ''they'' raised the price of diesel.

[@henrycarlson7514]

Interesting , Thank you

[@mikemulvey5789]

Solution: I fix my own cars. Other than transmissions work and alignments, i do my own stuff. Dont have the tool? Go buy it. Bought the software for my respective vehicles. Bought reliable vehicles from Toyota and VW. I have saved at least $10k in the last two years doing my own repairs. I buy my parts at the dealer with most stuff because OEM tends to be more reliable and for shits and giggles i always ask how much to replace part X, always over $1200. For something that takes a few hours in my garage or backyard.

[@jpprice14duh]

What about the additives big trucks have to add? I think it's called eurea or something like that.

[@chris.eskimo]

That's for pollution control. An EPA mandate. Not necessary for diesel engines to operate.

[@billyellery]

ITs called ad blue, and it’s for emissions only. Works without it perfectly fine.

[@yannnique17]

Why is the Torque vs rpm important, when you can use gears to get the same result from both? Or can't you?

[@guacamoleweiner69]

Diesel engine efficiency is 1500 to 2200 rpms. That's where they hit max torque. Lower gears help amplify torque while higher gears amplify horsepower

[@patricksullivan3919]

Taking the sulfur out. Is expensive. I’d say saying diesel is less refined used to be true. Not anymore

[@gregbrown9792]

This is a informative and good video.

[@clarencetrice4442]

😊😊 Rudolf diesel 1ST made the diesel engines in 1893 and there was a fellow a bit older than dad that use 2 work in town now in his mid 8OS he can remember when diesel fuel ⛽ was 1O cent a gallon 😊😊 OMG 1O 19 2O24

[@balamanohar4946]

In India, the price of diesel is less when compared to gasoline. In USA its opposite.

[@garyallen4486]

Diesel costs more because it weighs more than petrol therefore cost more to transport

[@scottayres607]

I disagree with that perspective. Up until the last few years , diesel was. Cheaper than gas (petrol) at least here in the United States. I bought my first diesel pickup in like 2010 and it was way cheaper than gas and compared to their gas counterparts, better fuel efficiency.

[@r7918]

So does that mean diesel cars are better than petrol cars in terms of durability and maintenance?

[@garydurandt4260]

What came first, diesel fuel or the diesel engine?. i.e. was the engine made first and then oil refined to create diesel?

[@davidleung2432]

The question then is why don’t we use only diesel for all automobiles? Wouldn’t that be more efficient? One fuel for everything. More economical? Who is standing in the way to prevent that from happening?

[@michaelboguski4743]

Is Vin Diesel the great grandson of Rudolph Diesel ?

[@nikowaqaisavou9371]

🤣🤣🤣🤣

[@A.M.2703]

Nice lesson 💯💯💯

[@geraldwalker1848]

Great video

[@buixote]

Diesel enginges produce more torque than gassers. Electric is catching up fast, though. Folks should check out *Edison Motors*, founded by a Canadian logging truck driver, who wants to beat Musk!

[@wizaaeed]

The problem is suddenly "some" community members are suddenly "woke" & started ditching diesel because it's not "green", but are using slow charging electric cars that have an unknown source of energy production.... This green sect forced the whole auto industry to install thousands of easy breaking "ecology helping" components for all diesel engines which made them no worth it.

[@athosgomesfonseca]

Short answer: torque.

[@mdmjeremiah]

I could smell the fuel when the guy at the end was pouring diesel out of that jug.

[@vijay.devotional]

How does it compare with aviation fuel?

[@antontsau]

Money money money! 30% less fuel consumption due to much higher efficency of diesel engine! If the motor consumes 50L per hour its significant, if 500L - no option other than diesel! Energy per litre or kg for all fuels is the same, torque has nothing to do with fuel ratio. Its possible to make high-torque petrol engine, not a big deal from american middle trucks to aviation (cessna172 petrol motor works on 2500 rpm max! My van diesel has redline 4000).

[@konnichiyawa_]

educational ✔️

[@rickchapman9232]

What about the 4 cylinder engines?

[@skaviationcrush3463]

How pilots get trained for an air show and how ATC navigate them ??

[@jameswest673]

The world runs on Diesel. Gas just gets people back a forth to work

[@Honest-liars]

Because diesel engines are built more robust and operate with higher thermal efficiently. Produce more torque.

[@WinningWinningWinning]

Diesel is not as flammable as gasoline. During World War II, the German tanks were running on diesel while the American tanks ran with gasoline. The American tanks would start on fire if they took a hit because the gas would explode.

[@afriendlyjsful]

But all those added things like DPF, DEF, low sulfur and so on have reduced the lifespan of a diesel. My truck is pre all that crap and it has and will outlast a new truck of the same class.

[@chrishelbling3879]

I love your channel.

[@Bobby-fj8mk]

Diesel has only about 5% more energy density than petrol. A diesel engine costs a lot more and it weighs more. Diesel engines have power and torque in only a tiny rev range so you need 16 gears in some trucks.

[@scottmcamis2127]

Torque!

[@RohitRaj-on6hl]

we need to make seaweed diesel

[@splagyetsi3287]

Diesel engines are designed to produce torque, if a gasoline engine was designed the same way they would also produce torque. Diesel condensate makes up 30% of a barrel of oil and the oil companies needed a market for it. Because diesel engines need to be larger than gasoline engines they can be installed in larger machines. These large machine would work just fine with gasoline engine but the oil companies need a buyer for their diesel. Industry has been convince by price and then propaganda that heavy machines must have a diesel engine.

[@roadrocket7770]

Gas is not reliable. Most gas engines are due for rebuild around 200k miles and the fuel burns faster due to lower energy content with the fuel itself. Most long haul trucks regularly exceed 1 million miles before a major tear down is required. Lets see a gasser even get half that while dealing with the demands and abuse diesel takes on a daily basis

[@dbxlbruh]

The idea of zero oil is absurd and naive.

[@peterolson8350]

The diesel engine does not have a higher torque at all (it has lower) than the petrol engine, just check the spec on each engine

[@andrewallen9993]

Diesel is more efficient than petrol so makes diesel powered devices cheaper to use.

[@BatBrakesBones]

Diesel makes a bigger boom.

[@rafaelvillamor9702]

DIESEL is definitely much cleaner and EARTH FRIENDLY than EVs if you think about how EV BATTERIES are made. And DIESEL is more efficient. Diesel is definitely the BEST INVENTION that ever invented

[@napinkpa]

Diesel engines produce more exhaust in NOx and some fine particulate particules.

[@robertcagle6156]

When Rudolph Diesel invented the engine the fuel we know as Diesel didn't exist. How did they come with the fuel?

[@mihapetek3418]

But diesel is desire, you were playing with fire

[@auro1986]

why? machines and vehicles that are heavy require fuel that has high density like diesel

[@icihicpcl]

My guess is taxes.

[@ts6070]

Not sure why Euro 6d/7 Diesel ⛽️ PHEV Hybrid vehicles 🚗 aren’t a common slight around the world? 🤦🏻‍♂️

[@MrHashisz]

Torque

[@miken7629]

Why not combine an electric motor to crankshaft to assist in compression stroke and increase efficiency and rpm. Bet green politicians would throw millions in r&d funds for such a hybrid engine.

[@JamesHGroffSr]

Its rated by the BRITISH THERMOL UNIT or BTUs There is more power in a gallon of Diesil fuel than in a gallon of gas also you are burning oil that makes Diesil engines last longer than gas engines because gas is an abrasive.

[@randywatts6969]

Diesel is the same as furnace oil

[@jackpayne4658]

Rudolph Diesel's disappearance and death in 1913, while aboard ship, are still unsolved. Suicide and murder both seem feasible, for various reasons.

[@richardlockwood9720]

Taxes

[@bradleypierce1561]

Won’t it be great when we are all forced to drive electric vehicles?! 😂

[@bryanpetersen1334]

This video serves to demonstrate why EV’s will never be the answer. Everything that makes diesel power great is missing from battery EV’s.

[@Takeitlightly6]

Diesel is good. But not in small trucks and cars because their sound irritates me to bits…cant stand the tuk tuk tuk noise.

[@zbici1556]

5:58 explosion every 2nd cycle, why not 4?

[@IgniteFireDance]

Emissions are slowly killing the planet though.

[@mauribush88]

Now I get it why learning anything new in certain circles is frowned upon. It is interpreted as an insult. Anyone hanging around me should expect a lot of 'insukts'.

[@hungryturtle1300]

You guys should have been already aware that there is an organization that controls gas production/price.

[@fathalwolf724]

Vin diesel

[@mohdfadelzain1214]

Haha EV still the best.. The best waste of time and money..

[@mickromer6199]

How do you think that electricity was created? Diesel engines mine the coal or lithium for the batteries.. transported by diesel trains and shipped by diesel ships.. people forget that EVs only store power they do not create it.. here in Australia they've installed Cummins diesel generators in remote areas so EVs can make it to the next charging station.. just because you don't have a tail pipe doesn't mean your EV hasn't created emissions.. and depending where you get your electricity.. also doesn't mean it's still not creating harmful emissions to create that electricity

[@GUIDELINES11]

Higher energy content. Save 9.22 minutes of your life. 😅

[@treavy1]

More torque nothing electric can do better and without nasty pollution machines can’t do remeber people #electricrevolution #evlife

[@terry9397]

Electric has its place, however how many mobile heavy machines do you see? Why do you think that is? Clearly people smarter than you or I have check this out and come to a different conclusion. In time things may change, but the technology is not there just yet.

[@jeffwombold9167]

Electric is not as magic as they all want you to think. Learn a lot deeper into the physics of it all, and you'll understand why. The average politician or teacher really doesn't know except from the popular (uneducated) common thoughts. Learn the differences between mechanical engines and electrical motors. They operate completely differently, and energy density is everything.

[@amitavachakraborty7599]

Diesel engines are not efficient in extreme cold conditions without adding particular solvent .
