[donorcarspares]

What a brilliant video! Understand much more how common rail works

@andimclanza...Hi..highly appreciate for your information...will find where the ECU located...but seems that Merc ML 270 CDI TDiesel 2001 got no ECU? Not mentioned in the Owners Manual at least..thanks a lot..

K Rgds..

[andymclanza]

@Hadiprawiro

It seems to me very strange, common rail NEEDS electronic control to work

to get more info about ecu search "Engine_control_unit" in wikipedia

Bye

Hi... I have ML 270 Diesel CDI 2001, please let me know..how electric current "on and off" control the nozzle valves..Are during its operation each nozzle solenoid remain charged? Which control activated and deactivate the nozzle solenoid valve?

Thanks indeed...

[andymclanza]

@Hadiprawiro

Hi

there is a component, called "solenoid" valve, that can be activated using eletric current.

When it is acitvated , it opens a valve that allow diesel oil to flow in the comustion chambher.

The solenoid is managed by the ECU that analize several engine parameter and calculate the right timing of injection.

I hope that now is more clear , for any other question just ask ^^

Bye

[goguletz]

this is not an injector from a CR injection. CR injection use piezo-electric fuel injectors. this is an injector from an old type of fuel injection, used in the past

[andymclanza]

@goguletz

ehm..ehm...it is an injector 4m a common rail...it was my final dissertation.

This is one was made by Bosch 4 FIAT diesel engine in 2000

[norwcav]

Great work :)

[l33tChachi]

Thank you for posting... nice job.

[clayson8080]

good jod

[boilingpoint2]

why with all the pressure of injection, the diesel does not burn instantly?

[andymclanza]

@boilingpoint2

Hi.

The concept on instantly rely on the timescale.

In the last part of the anim the timescale is in milliseconds, so the diesel oil needs some time to get adequate pressure and temperature to start ignition.

[schmitzischmitz]

@boilingpoint2

In europe we have strict laws concerning the discharge of grime(Black smoke) in the exhaust gases. You need those high pressures to avoid unburned diesel leftovers after the burning process due to the comparative long burning time of injected diesel gases that cause the black smoke. The higher the pressure the less grime leftover in the exhaust gas.

I hope you understand what I want to say. my german is way better than my English ;)

[domyaska]

great !!! excellent work !!

[ooMATTiAoo]

fiat kick ass, not only they developed this kind of system, they also created the multi jet system and the incredible multi air system!!

[alohabrianb]

Brilliant...well done Graci.

common rail injector

[MossyOak83]

lol the fuel comes out the A-hole lol

[saidsound]

is there anyone who has drafts of common rail injector for catia or pro-enginerring

[koffiejuffrouw]

brilliant, just brilliant

[balaun17]

Saw this is Diesel Power its a great vid...

[LilrobWestside4Life]

Great Video, explains the steps well and its also shows how it works.

[chinmaya2001]

Guys.. The stuff is self explenatory.

I have only one doubt,, please clarify.

In the last slide it tells the after injection raise the exhaust tempertature which caused rection in NOX...

Who is it possible to redure NOx at high temp?

[andymclanza]

Hi

The reduction of NOx due to high temperature was written on the FIAT/Bosch paper, and it was needed for the catalitc reduction

In reality high temperature rise NOx formation without any further post operation

[jburrows2009]

i saw it in dieselpower too, thats why i checked it out

[dieselwooody]

i saw it in diesel power too. its a great vid

[HicktownMotorsports]

Ha, this video was advertised in the new Diesel Power magazine so I had to check it out!

[Superstreet68]

Lol. Same here. Great video demonstration!

[domyaska]

ottimo video!grazie

[viabsim]

This video is much better than a MILLION words!

Talking of common rail ...

In fact, my Renault Mégane is a very good example of GOOD Environmental behaviour, because LESS fuel for a same job means LESS polution. And worse of all, the polution of the EXCESS fuel (because of the traditional poor combustion) is much worse than the pure proportional ratio to the GOOD quantity of fuel.

This is the best, talking of conventional engines. I am waiting for (really) good electrical drives.

[johndeerrm]

Excellent video, but dont higher combustion temps cause increased NOx emissions?

[geoff390]

Yer and that is why new enignes have EGR valves to lower the temp.

[scottybike]

yes higher temps create more NOx. The post injection is used to bring the temps down by inducing a non-stoichiometric combustion by the addition of more fuel.

I work at Bosch.

[JGMagoo]

VERY nice job. It is truly fantastic that FOUR separate injection events can occur in the time of one power stroke cycle. What (whose) system is this exactly? There are several variations of the common rail electronic system. This appears to me to be most similar to the Ford/Navistar powerstroke hydraulic design. Several other brands use a cam-operated design for the high pressure injection stroke.

[andymclanza]

Hi

I'm Andrea, this is the FIAT/BOSCH Common Rail system, it is used in many Diesel engine in Europe.

Bye

[KCharger9]

Thats the cummins system most likley. the 6.4l powerstroke is navistars first common rail which probably has the 4 injections as well.

[debosh1985]

yudfhh

[authmaax]

uhmmm thats how the extra torque is manifested

[walkandlookup]

Very didactic appretiate it

[suzettemelissa]

I have three vehicles that has this kind of system.

[njread1]

very good display of how common rail injectors work and as a mechanic it even taught me something aswell
