Great sales man I'll drop it in in the morning.
Thank you for this video 😃
You are welcome)
I didn't know Sean Connery was an expert on common rail systems...
Thanks for your comment
A talented man is talented in everything.
True or not, what do you think?
And, you also didn't know, that the global warming is absolutely Not connected with the global pollution of the atmosphere.
Sounds nothing like him.
😆
All info is true and very informative, especially diesel Duramax like we had in our oilfield pickups
Thanks for the comment! Subscribe to the channel! I'm preparing a series of videos about Common Rail.
Yes, except, that rail tube can get worned trough in about million years.
nice visuals for the voice over. Great movie. Bravo
Thank you! It's a pleasure to know that my content is visually pleasing and useful to you! I will be grateful for your subscription and likes!
Had me on my toes I was too scared to turn the lite off
Nice 👍
Very informative video! thank you. can you also do a video about high pressure pumps like bosch cp3 -cp4 and the differences between them and maybe a video about diesel tuning basics? would be very much appreciated!
Thanks, I'll try to do that. In confidence, I'm choosing CP3 ))
Contaminated fuel, low lubricity fuel.
As a mechanics i really appreciate this video ... congratulations
Thanks for your comment, I hope the video was useful!
My TD5 Defender has done 400 000 km so far. The turbo, the common rail system and injectors are still original. It has been serviced (mostly) on time. It has had good and shitty fuel. It is remapped and has a larger intercooler- a 2.5 litre turbo diesel doing 135kw and about 400Nm of torque. Diesels, turbos and ECU’s are not the things to worry about. This thing has been all over Southern Africa- doing highway and off-road. Sensors like air density etc are the biggest problem, but compared to maintaining a mechanical pump system I take electronic every day of the week.
I agree! Many diesel cars are very hardy and don't cause much trouble with proper and timely maintenance.
TD5 was designed to run on poor quality fuel as it was specifically designed for military use originally
I'm looking at buying a diesel cab chassis for work, and have never owned one. Everything I've read so far indicates injectors may need replacement a bit over every 100,000 kms, so 400 + is impressive.
I’ve got a defender td5 as well ,and it’s just turned over 400 000 km with original injectors and rail ,can’t stop,it
Pump-Düse over Common-Rail any day.
Conventional injection pump diesel is the best, no electronics, no sensors, no fancy technology things, they keep running even with bad fuel quality
True, but we aren't robots. We breathe air and a think called lung cancer exists. They're also low on power per cc and spew out black soot. I don't want my kids inhaling that crap, since I wouldn't be the only one driving these vehicles.
@em4703 , what car do you have now? ev?
@@autoadviser27791996 land cruiser, 1hz engine
So hard starting , less power, less tunability, worse drivability, worse emissions (more disease) , and worse fuel economy is better? Next your going to say a carbi is better than efi on a petrol car !
Agreed 100% from personal experience.
Now I own a 2011 GH Mazda 6 Sports Hatchback and it has a fuel injector system which is all that I know about these injector systems. I believe my own car's fuel delivery system that is not quite the same as this example in this video but I still wonder if maintenance on the engine fuel delivery system is as necessary on my petrol powered car as a diesel powered vehicle?
Yes. You don't have the same fuel system, but it needs to be maintained too! Good fuel is relevant for everyone! Watch lambda and other sensors, change air filter and plugs in time and your car will drive without problems!
Are the high pressure pumps self priming (in case air enters the system when performing a fuel filter change)?
Require manual priming
The high pressure pump is supplied with fuel from a low pressure feed pump (usually found in the sending unit assembly) which then flows through the diesel filter/water separator before entering the high pressure pump.
Yes or there is a hand pump on the filter housing
On my sprinter om651 your supposed to let the low pressure fuel pump run for ~2 minutes by turning on the ignition. This primes the filter automatically, as you can hear fuel flow through it pressing out air back in the main tank.
It's not like there's a rating system for service stations that show the quality of fuel that they're providing at the bowser. You're average consumer has no way of knowing which service station to buy the best fuel from.
Any fuel station give a clean fuel?
Choose a gas station according to how the engine runs after refueling, if there is no change, then you can refuel.
Wonder what the overall operating cost of modern diesels is compared to older engines. It boils down to radically increased maintenance costs including sensors vs higher fuel consumption.
Yes, maintaining a diesel is not as cheap as it seems. But with proper maintenance, diesels run great!
Nah not radically increased at all.
Engine oil for Diesels is fairly cheap, Fuel additives to help lubricity and maintain a clean fuel system are also cheap, EGR Cleanout is a diy job.
My diesel car has 250.000km on it and the drivetrain can do over half a million but the transmission will go around 500k.
Fuel mileage is really good.
I check my ECU, fuel filter, injectors, sensors, fuel rail and fuel filters every day for a safe and efficient drive
It's a wonderful habit!
Common rail is far simpler than mechanical timed fuel injection. It has electronics but this manages timing, while the pressure is managed by a valve on the rail.
Cool video, im just curious, was this made by chatgpt or an ai bot of some kind?
Thank you ! Didn't guess twice!
It seems so based on the responses of @autoadviser2779. Some of The responses seem too “perfect” yet still a bit “off”.
Hi. When the car is cold everything is fine. When temperature 90C on 4 gear, power goes down. Glow plugs new. This is high pressure fuel pomp or injectors damaged ? Thank you in advance
How much diesel have you in the tank????
If you have 5-10 L diesel in the tank then you have that problem
Especially if you are uphill and the outside temperature is high

Fuel quality is key.
Do your maintenance.
The older Bosch commonrail systems you find in most Eurodiesels from the 90s into the 2010s last a long time.
Lots of diesel vans and cars here will still have the original injectors and high pressure pump even at 300.000-400.000km and 20 years old.
The high pressure pumps pretty much never die when there are issues its the injectors or a sensor.
I need to do some research into the exact types of pumps Bosch made during that time.
Mercedes used Delphi Piezo Injectors in the OM651 engine and since they were junk they went back to standard Bosch solenoid injectors in the OM654.
The older OM611 and 646 aswell as the 3.0 V6 OM 642 were friggin indestructible, they were made during the golden era before everything started being complete junk across the board from all brands.
Standard Bosch Solenoid Injectors are the best commonrail injector for cars and vans.
Cant speak for large Diesels in Trucks and Buses.
Yes, I agree completely. I have a diesel bmw e46 with 300k km mileage, the injectors were like from the factory and there were no issues with the fuel system. Engine m47n 2.0 diesel
How long is prolonged idling?
There is no need to warm up a diesel car, the diesel warms up better while driving. It is better to drive straight away, but do not accelerate, allowing the engine to warm up gradually.
@@autoadviser2779, thanks!
More than three minutes
@@llewvirtue861, thanks!
Too bad that the picture does not match the commentary half the time.
I agree with that! The main thing is to voice the essence of the problem!
I was about to comment that as well!!!
Cp3 is the best high pressure pump for a CR
Share more about the experience of using it? We would be grateful
CP3 has one piston only, and earlier models wear out within 300 000 kms easily. The newer, improved ones are better, but nothing beats CP1 when it comes to reliability, besides minor fuel leaks that can be fixed easily, it outlasts the lifetime of the whole engine.
@imrebese5502 cp3 pump have 3 pistons. And cp4 have 2 pistons. Google is free
water in the diesel -- a comon problem of petro stations -- and biodiesel, - these are the most common culprits.
Yes, and it’s very harmful for car fuel system
@@autoadviser2779I fitted a water separator to my car, and its amazing how much water it collects over the period of a month. I drive a 39 year old mercedes with an inline low-pressure injector pump, which is less finniky. I add a bit of engine oil to the diesel and avoid bio diesel as good as possible.
Obvious chatgpt video.... Such long video to state the obvious, particles and bad fuel can damage the fuel system wow
It's worth revisiting the video, you'll find information there about more than just clogging!
just preserv everything on a shelf. get your self an old style inline mechanical pump. preferably from an old merc , if you can find one that fits yours engine layout. do get the injectors too. no electronics involved. and not allergic to today's low quality fuel. allso keeps your common rail system in good condition, where it belongs. on a shelf in the workshop.
Is this from your experience using it or in theory?
@@autoadviser2779 i have converted engines from different solution back to regular mechanic injection .
Those engines , all of them managed better economy and more favourble tourqe curve.
Quality fuel, that's why they put bio diesel in it?
That doesn't make it lower quality, it just brings other problems for older cars as biodiesel can react with older rubbers or gum up at lower temperatures. Fun fact, biodiesel, even at 7% by volume, offers better lubricity than the high sulphur diesel fuels of older times.
Not every engine will be able to run on biodiesel.
Picture an earthquake......this is what opening the zipper of your jacket is like. Picture a nuclear explosion.....this is what happens when you burst a tyre. Picture aliens using laser beams on their spaceships.....this is what happens when you switch on your headlights.
so what kills it ?
Watch the video again!

Everything kills common rail
This is over dramatic. The same things that damaged the older mechanical diesel fuel components damage a common rail system as well. Poor quality fuel regarding Sulphur content is bad for all diesel injection systems. Storage tanks at fueling points are another because of moisture and bacteria contamination and the fact that many fueling stations do not have adequate filters on their pumps due to cost cutting on maintenance. The next main factors for fuel system damage is the fuel filter in your vehicle and how often it is changed. Diesel fuel lubricates the fuel system so anything that reduces that lubricating quality will cause wear problems. A common rail system circulates a lot of fuel so if you run your fuel tank at a low level often then the fuel will heat up more on longer runs and this can reduce the lubricating quality of the fuel and it can also lead to condensate moisture forming in the fuel tank and even bacteria growth so the inclusion of a clear glass container before your fuel filter is a good addition to see if you have a moisture problem or bacteria growth. It's all about good maintenance and observation.
This is my thought exactly. All of these problems are not isolated to common rail diesel injection systems. They are related to anything mechanical.
A lot of people drive a car for a couple years and they don't care about fuel quality and maintenance issues, which is a shame.
Climate change... 😂😅🤣

I put liqui moly and the pump died
That's too bad. What model of car do you have?
modern? its 20y old ffs :D....2 decades sound better.
20 years old is still modern!
@@autoadviser2779 nothing better doesnt mean modern. :D:D:D

You're wrong. Try generating it and see what happens)
@@autoadviser2779ok,i have never tried too so fair comment. But there is an awfull lot of a.i generated content appearing on youtube with genuine content creators being pushed out by this content,mostly being cancelled by y.t(demonitized,month long bans,shadow banning,etc etc) in an attempt by y.t to be the main content creator thus getting the majority of ad revenue.
My comment was not ment to be hurtfull and i di hope u dudnt find it so.
To be more constructive in my comment rather than a dismissive “its a.i” maybee narrate yourself? Or if you do try to sound less robotic, i found it took a long time to make a point,maybee you were filling for more ad time? And repetative. I do hope your channel grows and you make a good living from it.y.t needs more genuine human content creators. Well done you for getting to this point! I wouldnt know where to start.🙏❤️.
11 minutes to say keep fuel and filters clean.
Know another secret, post it here, it will be helpful! Thanks for watching!
This video is not 100% true
you can't be 100% sure of anything, not even yourself. Anything you'd like to add? I'd appreciate a good addition to the information.
Talking OK, but the visual are just dummy moving pictures. Wasting time.
Thanks for the opinion! There is a lot of original content on the channel, check out the other videos with other video content.
Unrelated stock footage is complete aids
Ted. Hi, I am a diesel engineer. What you have just presented here is extremely poor.
At least half the footage I saw does not relate to the subject,
get real and educate us properly, it is a very important subject.
Poor for whom? I agree, for a diesel engineer you need more in depth information, which I don't have. I am a simple car enthusiast who is interested in the performance of his car because I like cars and want to understand them a little more. This video is my interpretation of the information I have. And I'm sharing that information with you. It will be wonderful if you have something to add on this topic, all car enthusiasts would benefit from reading. Good luck on the roads!
@@autoadviser2779 Hi, Sorry If I offended you, I don't have any complaint with the dialog, It's about the footage shown that doesn't relate to the subject. Don't be discouraged, keep researching,
Ted.
