- How the EGR & PCV or CRANKCASE VENTILATION WORKS  The EGR system is there to reduce nitrogen oxide, but is there any evidence it actually works in the first place or if it works once the vehicle gets a bit older
There’s a few questions you need to ask yourself, but first watch the video to understand the difference between EGR and crank case ventilation - Auta a dopravní prostředky
EGR is so misunderstood… it reduces the amount of oxygen and Nitrogen in the cylinder by replacing it with CO2..air is mostly nitrogen ! NOX is formed when an engine burns lean and hot.. when there’s spare oxygen (lean) .. when you cruise under light throttle the engine is literally too big, in displacement to be efficient and pass emissions … if there’s no EGR it’s running lean and hot
EGR is effectively variable displacement, so it might turn a 3.0L engine into a 1.5 by replacing half the o2 with CO2 allowing the PCM to inject half the fuel, providing cruising power while not being lean and making loads of NOX which eventually causes acid rain after sunlight reacts with it in the air ! In other words EGR allows fuel economy while under light load without causing crazy bad emissions ( ask the old boss of VW from 2015)
At or near full throttle the EGR shuts off and it runs rich , rich enough to deplete all the oxygen to the point where it makes almost no NOX even tho it’s high EGT when rich basically all the O2 becomes CO2 and not NOX!
In other words with no EGR your engine makes easily 100 times more nox because the engine is way too big at crushing speed, you can run it richer and it will make
The warmer egr gas entering the manifold … after the egr cooler takes the edge off .. isn’t a problem as self regulating, it’s only doing EGR at light load and as it’s not lean because of the EGR it’s no so hot in terms of EGTs
The potential solution to carbon build up is to suck in the EGR downstream of the DPF then it will be significantly cleaner as most of the soot has been trapped by then !
Emissions , fuel economy and tuning are far more complex than most people think
Plug in an OBD reader every common rail diesel has a EGT sensor
Used to work in aerospace , that's why I like Toyota build quality ... Your videos are tip top... Especially this one
When I got my 2015 Hilux tested, the guy commented on how clean it was when he did the emmisions test, I didn't tell him I had the solution fitted, great video, definitely give the stand up a miss, 😅😅😅
Listened to it all. Have 7mm in for 1 year now and it’s a treat.. legend. Thanks for all the info and agree with everything!
You are correct in what you say. If you want more power buy a car with bigger engine and often bigger fuel bill. The 1KD is a mighty engine if you use it as designed. It will serve you well if you drive it accordingly and within the design parameters. Service at required intervals also helps !!! Great information once again Anthony. Thanks for supplying this again. 😊
I've had EGR fully blanked for about 6 years, nothing but improvements. ScanGuage shows 86-88c, fuel economy improved and it's also awesome how much cleaner the oil stays between oil changes. Before i cleaned the intake, installed fresh injectors and blocked the EGR the intake and EGR was choking to death on soot, ruining performance and causing higher fuel consumption. How is that cleaner or better for the environment burning an extra 1.2 litre per 100km? 👍
I always make sure all my garden hoses have a 7mm solution at least! Hahaha 🤣
👏👏👏 common sense is great 👍 who wouldn’t listen to the end 🤷♂️
Bwahahahaha... garden hose... curry... best video yet! ... and are you kidding me, I was still listening at 15mins. You told me what I've been wondering for a few years now. Thx mate!
I am glad someone confirmed it exactly how my mechanic explained it to me.
Love the garden hose description, I describe egr as its like farting in a bag and then breathing it in! Hahaha! Great video.
I’m in Canada with a Colorado 2.8 diesel. And the talk around here is that the EGR lowers Nox and reduces EGT. I do see a lot of intakes completely blocked off with massive amounts of soot. The soot is mixed with oil vapor from the crank case ventilation system being sucked into the turbo then pushed through the inter cooler and forced into the intake where it is mixed with soot from the exhaust…
Actually, different manufacturers of cars have high-pressure EGR valve and low pressure EGR valve. Low pressure EGR valve comes from the other side of the DPF which is filtered and way cooler by the time it gets to the intake these EGR valves in my opinion are fine.
But the one on my car is a high-pressure EGR valve straight from the manifold all that crap going into the intake making the engine run poor which runs cooler when I block the EGR valve the EGT ran a lot hotter was told by My tuner to go careful until I got it there once it had been tuned it run normal temperature block the EGR valve it will need mapping software update someone that knows how map a car and not a generic map. So the question is, does your car run hotter if you delete your EGR yes I think it does unless you have it Mapped because your engine will have clean air and will burn the fuel more efficient properly less smoke more heat
Wow Anthony thanks again I think this is one of your best video as it was a question I needed to ask at sometime when I bring the old girl over to get the injectors replaced from the Prado Hospital.
My Old 120 2007 1KD with 360k has a complete EGR cooler block from carbon I reckon so I don’t it’s such a problem now .
How I picked it up was from one of your educational Prado videos were you at the end of the video reaching down the left side under the EGR cooler and with one finger lifted a type of butterfly leaver up and down and said just checking?
So I went out to my 120 and tried the same it was rock solid stuck close then tried carefully parrot nose pliers still no movement so left it at that
Thanks again cheers
I don't eat my shit, why force your engine to eat its own shit?
VERY IMPORTANT!!! DONT DELETE EGR!
You will have clean engine, additional power and this is bad for mechanics and dealers income 💰
EGR what they cause
With ,, reduce emissions when operating correctly , This is the key part correctly
Effects ,, egr introduce contaminants into engine fresh air ,, this does reduce power and increase fuel consumption ,, pcv mist and egr soot form a sticky carbon paste ,, inlet butterflys become clogged and engine efficiency is reduced .including throttle response
Reliability and service
Egr valves should be cleaned every 50,000km
EGR cooler should be cleaned every 50,000--100,000km
Inlet manifolds need cleaning every 100,000--150,000km
Injectors last alot longer when not exposed to debris
Most of the above has appeared thru out car and truck industry over the last 40 yrs
EGR petrol diesel direct /indirect injection , and carburettor equipped has always caused issues
Major engine damage can result from heat exchangers failing ,, this occurs in other ultra hot heat exchangers in certain industries . Once the cooler fails in automotive if engine is not stopped quick enough cylinder head failure is common . As with all overheating piston rings loose tension and high oil consumption occurs .
Summary If u going to keep your EGR service the system well . Prevention is key .
And for the people who ""disconnect "" there are benefits also
When I bought my bmw 5 series (M57 diesel), that was the first thing I did to it. Blocked off the c*nt. The valve itself was building up soot and intake was all oily. Used to block them off on tractors aswell. Mostly fendt tractors with deutz engines. They always had problems with egr cooler cracking, so we did a cheaper fix and threw it out from there.
Definitely exhaust gas entering the system makes things far less efficient. You want the intake charge to be as cool as possible.
NOx emissions targets are based on combined driving cycle. Load and cruise. Because they need every bit of efficiency under load, there's very little EGR flow.
To offset the high NOx produced under high load conditions, they give max EGR flow for low load to try and break even on the total NOx emissions.
20% EGR gives the most reduction in NOx, but even 5% can give a 40% reduction. This is due to the exhaust gas increasing the heat capacity of the intake charge. The soot absorbs heat and reduces direct combustion temps to below temps where NOx is produced.
It's all a balancing act to pass emissions regs, but does it really make a difference when you have to do more servicing using more materials.
You are spot on 100% If anything it takes a little longer to heat up from cold because not recycled. Runs and boosts better when blanked. The most noticeably thing was getting rid of the blockage in the exhaust (DPF), turbo will last longer. Like running a marathon with a gas mask on with your hose from your ass connected. But need to get it all mapped out on the computer. I don't think you have the add blue injected in the exhaust yet in OZ (pig piss, urea). I think we have been had big time with this climate change h 0 ax and the jabbers. Get ready for the truth to drop and people/leaders being locked up. Just started in the UK.
EGR is like trying to cool your freezer with a blow torch
Total agree 👍 👏 with what you saying. I agree with you 💯
Can you use the egr blanking plate with the 7mm hole on a Holden Colorado 2.8 with a dpf ??
The ERG operation is comparable to the albatross flying in ever decreasing circles .
Can I do this blanking plate to Mazda 2.2 diesel ? I have cleaned the manifold egr and egr cooler. Running great.
EGR reduces the temperature peaks during the injection process, resulting in a reduction in NOx emissions, while minimally changing the average combustion chamber temperature.
Volkswagen uses low pressure EGR plus Adblue also known as DEF in some vehicles. This means that the cars are equipped with a DPF and use the clean exhaust gas after the DPF.
However, this means that if the DPF is damaged, your engine and turbo are toast.
Did have a laugh don't worry 😂
Apparently an egr system improves fuel efficiency through a thermal hack.
Food for thought.
Just disconnected the power to mine , runs great
It actually runs smoother , and ssangyong is amazing doesn’t give u engine light when you unplug power to egr
Basically, the cooler the air going into the engine, (which is at its coolest when coming direct from the Turbo, NOT the the hot gases from the EGR) the better your engines going to run... 😁👌
bahahaha bahahaha bahahah cheers for clearing it up intake that is
Measured EGTs pre and post Stage 1 Remap with EGR Delete and 2 3/4* exhaust. Less than 20 degrees or 5% increase at stock EGR open loads. My guess Delete only, no Remap the temperature increase is negligible.
I was taught if u remove the Egr the combustion temps get too high so the fuel would pre-ignite before tdc occurs, going highway speeds wouldnt do that because of all the air getting force through the radiator cooling the coolant but if ur sitting there idling with the engine hot there wouldn’t be enough air getting force in by the fans/fan to cool the block down to stop pre-ignition so it’s a win lose situation
Careful who you get taught from
catch can is good on older diesels that have more blow-bye.
I did put the KAON 7mm blank on my 1KD-FTV 120 Prado. First I noticed the MAF value at idle went up from around 7 to 12. Kind of makes sense since the engine must compensate for gas volume lost by blanking the EGR. Second, the engine light came on and the scanner showed a P0400 DTC. Clearing the DTC only to return in a couple of days. Ended up removing the blank.
Question: is the MAF really supposed to go higher when blanking with the 7mm KAON?
Yes because you've changed the flow rate with the plate. Might need a larger hole to get rid of the warning light.
under load will produce more heat(more fuel+ more air = more heat), light throttle it will be cooler anyway regardless egr or no egr.
With older traditional engines the sole job of an EGR valve in the rocker cover was to vent the crank case...before that it was just a straight pipe out of the engine block that vents to the ground...once they started with EGR and resurculated polution control pumping shit back into the engine ...that was the end of good power reliability and long engine life...by the mid 80s it was really bad...long before most cars had turbos !!!
Your a bit confused
Watch the video & listen
The crank case venting has nothing to do with EGR.
'Older traditional engines' didn't have EGR, you're mistaking EGR for PCV.
Also those old engines before the days of PCV were not always reliable, I don't understand why so many people have such a blinkered sense of the past, as if carburetors and distributors aren't total disasters that are always screwing up, as if non-turbo, mechanically and indirect injected diesels weren't gutless by today's standards.
Diesels reached their peak efficiency around 1998-2006.
Egr makes engines run cooler because of the poor combustion they induce. Some Cat engines take exhaust gases AFTER the DPF for recirculation. Manufacturers should do the same for cars and pickups.
The "tiny amount " of oil in the breather vapour coats the inside of the intercooler, vastly reducing its efficiency.
🤣🤣🤙🍻
Show us your face we wanna see it👍👍
My prado puffs white smoke when it starts then it stops right away, what could cause this?
Egr crack and leaking
If you use a blanking plate put a small 7mm hole in it.
To summarise listen to some guys rant on CZcams delete your EGR & lose your factory warranty
Going outside now to find me hose lol.
It will run so good it will implode
🤣
All diesels run better with out so called pollution equipment wether a hilux or a cummons,cat or any other large commercial engines and they last a lot longer but I know you have to follow the bs narrative
Up to 50 % percent shit recirculating ,if thats not a bad thing what it ?
Towing at 120..130..... all the Toyota owners manuals i have read recently say top speed while towing is 100km/h. ..just saying ;^)
Must be a better way of explaining it, you lost me through the rant.
Blah blah blah lol
