Silent Diesel Killer…Diesel Exhaust Gas Temperature (EGT)!  

God your explanations are on point, easy to understand the more complex areas which is rare. The humour just adds that bit more “flavour”. I’ve been into diesels for 30 plus years and you have explained all my years of knowledge into a tiny window of time…congratulations.

Sometimes the algorithm blessed you with a channel possessing the precise ratio of entertainment/education. I’m buckled in now sir please continue!

That 1776 line was pure gold!

Peterbilt tech here and i cannot tell these guys enough how much heat the engine retains with out the EGR on these newer engines, not uncommon to see a newely "offroaded" engine, torch a head or turbo shortly after. Great video!

Finally someone is on point with their facts. Good video. Great info!

Clicked on a Busted Knuckle link and stayed for your knowledge and sense of humor. First video I've watched of yours and it shan't be the last👍

And as always, both educational and entertaining! Good stuff!

My jaw has dropped. What an excellent, witty delivery on an outstanding topic! My whole life was gasoline, much of that high-performance stuff. then in 2018, my life changed, ram 3500 Cummins stick shift. Fast forward to now and probably having watched thousands of diesel related videos. I suddenly realize that I have no gasoline products anymore that I use regularly. There’s the truck, tractor, skid steer. call of them diesel, all of them turbo charged. Much appreciated video, Greetings from the Fort Knox Kentucky area!

Great video .. really appreciate the way you dumb it down and make it entertaining for a simple folk like me, makes for a easy watch thats extremely informative

These videos are packed full of information and freedom. I'd love to see a video on diesel engine runaway, it's got to be pretty full of science to be explained!

3rd generation Automotive Engineer 43yrs persona trade life. Add 2 extra generations, for a whole lotta yrs knowledge. Nice to hear a guy tell it like it is. No BS, humour abounds which is very cool. Keep up the cool content buddy 😉👍👍

Never watched any of your content before. I’m glad I found ya. I tow my rv over many mountain passes and shifting down and getting the rpm’s up over 2000 will almost always bring the egts down to a reasonable number. Besides I kinda like hearing it.

Informative AND hilarious at the same time.

Underrated channel!!! Great content!

i hit both buttons. i was not at all ready for the humor and actual info. well done sir well done

wow, that was great! I understand so much more now. Thank you!

I learned so much from you! Thank you!

Keep up the great vids. Entertaining content on many levels.

incredible video, top quality short sweet explanations and very entertaining. My favorite part is "my truck has disk brakes so I used disk brake grease"

your a trip! love the description. i recommend green sticky impliment grease or bacon grease for the tap.

Just graduated A&P school and these same laws were taught to us. Good video 👍

Good explanation on EGT. Now do a demonstration on EGT with a water/alcohol system and how it affects EGT, Fuel economy, and power and why it's better than an EGR system.

Helpful and entertaining. Great work

A great video. Thanks for sharing 👍

Very informative & entertaining. Subscribed!

Love the humor and video quality.

Great presentation, you didn't even have to use a teleprompter.😎👍

Are we gonna ignore the fact he reloads his own ammo .... you sir are a great American 👍

I hit 1600F+ on my 2.0L TDI, it came with a EGT probe before the turbo. One other thing you can do that you didn't cover in the video. Water-Meth injection, I plan to do that to lower EGT. I like the presentation and information.

You definitely have to be related to Vice Grip Garage! (VGG) Keep up the awesome Vegias!👍🇺🇸

You remind me a little of Derek aka vicegrip (compliment) and Cleetus and the guys doing science experiments. another compliment. I'm surprised you don't have more followers. great job.

just wanted to say your video is super entertaining and funny 😁

Thank you! Entertaining and Educational

wow this is gold! thanks bro for the humor!

As a new Duramax owner ...... Subscribed, and bell smashed!

Great video. Thanks. 👍

Life on a semi engine they are now designed with all this emissions crap end up running hotter temps supposedly to burn off pollutants which means your engine is cooking life out of its self which will leed to a early failure plus they claim you can go extended oil changes but thats only leeding to more stuff in engines oil system flowing around killing rings bearings and components..so you use to get up to 2 million miles on a diesel if maintained good but now you get 600-750k miles and thier shot sometimes around 350k to 400k miles then probelms happen ...EPA is a joke thier mission is to kill our ecomany any which way thier comunist heart tells em to do it...its un-American!

great videos sir!

Full of comedy gold. Love it

Papi?!? Went through a rough time lately but I recently found my diesel pa-pa again! You just made my week man thank you! I appreciate the knowledge, where did you go to school?

Hey man didn’t realize you were local to me haha. I saw you passed by the Northgate intersection on the 7.3 pull. Great video

Though I'd throw this out there, the oil squirters are one of the main reasons the pistons don't melt. I have a 3406e 2ws that was inframed by the owner, they removed piston/rods without removing the oil squirters, it went 16k miles and I bought it. 2nd time I pulled a trailer at 925 post turbo temp it melted #2. They were bent just enough the piston wasn't cooled properly, but compared to the new squirters they looked identical except for light scratches.

I’ve seen, what may be a 20ish mm round, a reload set up and lots of combustion science for diesels. Think I’ll sub now.

Good sir, you have earned a like and subscribe!

Great video.

Cool vid..thanks.

Definitely need to see some follow up videos - - with a water injection kit installed

47 days, congratulations brother!

This video got me I gotta see it all now 😂

Great presentation, and hilarious as well. Your excursion will really move, especially for a big girl. I’ll have to look for it on your channel!

A truck a dog. A brilliant presentation

Sweet video, how about injection timing how it affects exhaust temperature and cylinder temperature and turbo inlet and outlet pressure the science. Loved it...

Scania has recently came out with an Exhaust Aftertreatment System that eliminates EGR. All Emissions mitigation happens behind the Turbo and trough engine tuning. Pretty amazing honestly I wonder what the effects of no EGR System has on the engine.

The science and engineering behind Diesels is awesome. Way more interesting and intricate than gasoline engines to me.

Awesome video, 😂😂 too . Just changed the intake horn, and hot & cold side pipes. And not to mention a 140 fass also. Gotta save up now for the ct3, get a diesel they say. It’s like owning a boat & jeep at the same time. If only I had my money I spent on the jeep. 😢

As a guy who has a Cummins in his Ford, I can confirm that I have both a better body and a bigger pipe than the other guys.

Jamin, I thoroughly enjoy learning about diesels with you. And I’m not really Adam Sandler.

Excellent Explanations - ^ FUNNY ... sub'd.

“Hit the I believe button and keep going” that’s good.

i love the ghost rider reference "ill trade yah my hunting dog lucky, hes got one eye and no nuts." classic

Great video. Make more.

Awesome Video !👍

"It's actually really simple if you don't think about it." 😂😂😂😂 that is getting added to my lexicon

the lighter example is an incredible demonstration of frequency, the frequency of the movement of your hand keeps your from being burned or shocked, the slower the movement or frequency the more time for energy to transfer to cause damage.

I ran my early 03 5.9 Cummins at 1600°F EGT for 20 minutes straight. I wouldn't recommend doing it, but it was during an emergency, so that's the only reason I did so. I usually keep it in the 400° to 600° range as it is happy at those temps.

I dig your commentary

Nice!

Q: are the temp:voltage outputs of K type probes (supposed to be) standardized...or do diff. manufacturers' probes produce diff. ranges (diff. ratios)?

Keeping the engine revved up towing equals more CFM coming out of the turbo equals more cooling of the engine and combustion chamber. Bigger intercooler after cooler water methanol injection

what's better for the engine under extreme load and fueling? I've only watched the first 6mins of this video, so if it's answered later please feel free to say "watch the damn video". 1. higher rpm / lower gearing, with slightly lower boost and EGTs 2. lower rpm, taller gearing, but slightly higher boost and EGTs I'm guessing there's a trade off between options 1 and 2 due to the 'recovery' time between combustion cycles being reduced with higher rpms. is this true? i usually try to be a option 1 driver, as i've always focused on EGT and lowering strain from over-gearing. But am i wrong? Thanks, and excellent video too!

drum brake vs disk brake grease. glad i wasn't drinking milk. subbed.

Very interesting stuff to learn. I got a question. So will reducing the intake temperature, let’s say with a big heat exchanger after the turbo compresses the air, help lower the exhaust temps? If so is it significant?

I like how you point out how the thought that the emission control and noise control systems in a modern truck are the largest exhaust bottleneck is false, and the downpipe is the real major issue. The first generation emission control systems WERE downright awful for performance, and also were not durable. They used packed crystal catalyst. About the only thing truck owners liked about them is the fact that they increased emission noise not unlike a glass pack on a motorcycle, something neighbors hated about them.

Bahahaha that was one drop 😂😂😂😂

Best timing for compression lower the more boost depending on voltage ⚡ fuel

What temps do diesel trucks normally run? My 2 liter passat has an EGT limiter set at around 1675 which is the limit of the turbo before bad bad things happen XD

What tunes are you running on the excursion

For the nerd explanation of a thermocouple: When you bind two metals together the point at which they merge forms a diode, much like a crystal in a crystal radio. This point is basically a semiconductor junction but unlike other semiconductors has stronger properties . All diodes have all the following properties, but each one is built to maximize one and exploit it.: 1. They conduct electricity more easily one direction than the other. 2. They completely block electricity on the direction they provide resistance in up to a certain voltage threshold. 3. They create a small amount of light when electricity is run through them. 4. They transfer heat from one side to the other when electricity is run through them. 5. When heat is forced from one side to the other they generate a small amount of electricity. 6. When exposed to light they generate a small amount of electricity. 7. Properties 1 and 2 change in threshold based on temperature to an amount based on material. 8. Properties 1 and 2 change based on light exposure. Thermocouples are designed to maximize the 7th behavior I listed, while minimizing the others. They are also designed to have that behavior appear in the most reliable manner possible. Hence, when attached to a voltage source, a known resistor load, and an appropriate electrical measurement circuit, you can read the heat the that the thermocouple is tied to with a high degree of accuracy.

Hi, I'm new around here in your channel. Very interesting explained everything, but I am bit curious about that vacuum thing after the MAF sensor at the intake side. What's its purpose and how do u name it? Thanks in advance 😊😊

After watching this video about egts for diesels how about weather egts are important on the new twin turbo engines. I'm sure gasoline it is not but there might be people out there that don't understand.

6:00 and this is why you can melt pistons if your engine leans WAY out...... . the combustion temp gets a LOT higher.... and despite only being in their for 25% of the strokes (and really, its more like 18-20%, due to valve overlap, expansion, ETC) to combat this... modern engines, even gas engines, use "piston squirters"....... they shoot oil on the bottom of the piston

Ideal Gaslaw... I'm picturing exponential gains or losses with pressure X temperature.. Edit.. So does that mean a Detroit Diesel's hold their hands over the lighter longer?

You're like Burt Kriesher's knowledgeable older brother

😂 I've never seen one of those old school boost gauges get spun around like a clock

What about if you add water/methanol injection. Will it lower your egt?

I wish I knew not to run the tap in all the way. The first time I did it I thought I used the wrong tap because of how loose my sensor was.

11:56 simplest solutions are often the best.

Keep them old minty Diesels Alive Boys 💪

In diesel - more fuel = higher egt Thats why leaky injectors can lead to broken engine. Cheers from 2.0HDi (Citroen) tuned from 136 to 210. It didn't need more than a hybrid turbo and few mg/inj to do it. And yea. Turbskie is smol. But makes power.

Great video! Water meth injection will also lower egt

A lot of people hate on EGR because they think that it clogs up their intake. It's not that, it's actually the PCV valve (aka my mortal enemy). Let's think about that. Normally, your exhaust should have gas and dry dust flying out the back. So, it doesn't make sense for dry dust to cause a wet goopy mess in your intake valves. You know what does cause wet goopy messes? Oil vapors. The reason that the PCV is my enemy is due to the way it's implemented. It's there to make the air pressure on top of the piston be the same as on the bottom of the piston. So, like, WHY NOT ROUTE THE PCV FROM THE CRANKCASE TO THE VALVETRAIN? Why would they ever choose to spray the intake with an oily mist when they could spray the valve train with an oily mist? I hope you can see why I don't like the PCV. P.S. you engine experiences something called "pumping losses" at low rpm. The EGR actually helps to mitigate that. In short, it basically allows you to open the butterfly intake to like 50% but you only get 10% power which is good for low rpm pumping losses (numbers are just made up to illustrate a point).

I used a thermocouple and would never let the engine run over 650deg Celsius normal driving. When racing however i would regularly bnild dngines that could see 800deg quite safely. The biggest killer for any diesel is poor quality fuel.. and possibly oil starvation... or maybe water ingestion...and occasionally a failed governor...but there was that one time the timing belt snapped, that shaffted the poor girl pretty hard. I always measured at the down pipe for ease of fitting.

I like that part about not being proud.

I've had my 6liter (big injectors single turbo) to 2k degrees SEVERAL times on the factory pistons 🤣

Related to Derick from visegrip ?

RIP that boost gauge 😂

Chts cylinder head temperature before egts ceramic forge. Billet

Your wife will love how much quieter the truck is! Yes!

Are you The Fat Electricians brother? You look like twins 😆

MALS-36 !! Spent a few years with them at BLDG 638. 2010-13. You look familiar.
