Quoted from Wikipedia : "The DV4 is available in two versions:
One, an 8-valve design, uses a Borg-Warner KP35 turbocharger but no intercooler. This is the same turbocharger as the Renault K9K Diesel. It is Euro 3 compliant, but will receive a Diesel particulate filter from 2006 to make it Euro 4 compliant. In Ford, most Citroen and Mazda applications it uses a Siemens SID804 or SID802 common rail injection system, in Peugeot and some Citroen a Bosch common rail system is used."

Recently, Tata has reintroduced the DiCOR engine, initially in metros I assume, as BS4 diesels haven't started arriving in my state yet, in the form if the new Indigo CS eLS and eLX. The DiCOR name has been dropped, and it is now called the CR4 engine, possibly meaning Common Rail BS4.

Tata claims to have made improvements to the engine. Hopefully, there will be no more frequent and premature pump/vacuum pipe failures due to clogging, especially when the BS4 fuels start coming in.

IMO It's possible that the entry into BS3 markets is being delayed because they don't have BS4 Ultra Low Sulphur Diesel pumps open yet, which might be needed to prevent clogging.

If you look at the people who have had problematic DiCOR engines, it's mostly failure of the fueling system. this is likely a function of the bad quality of diesel available across India, and too sensitive monitors. Hopefully BS4 fuel and better tuned sensors will mean a fresh new start for the DiCOR saga, and that common rail motors will become commonplace.

When you say problematic DICOR engines do you mean TATA only or you have used it as a generic term? I have DICOR engines of both TATA and Mahindra and am yet to face any fuel related problem despite filling up at some of the most atrocious and dubious places to fill. lol.

Dicor is a brand/trade name that tata uses for its common rail systems.

Similarly Mahindra uses CRDe

[nitrous]

Only the Dicor 1.4 that was launched in the IndigoXL was troublesome.
Probably, this 1.4Dicor Version2.0 is now sorted.
Probably!

Then how come the Scorpio CRDe engines have been running on the same fuels for years now without any of the similar complaints. There is no excuse for Tata's shoddy quality control. They key difference is that Tata sources it's CRDe pumps from Lucas/Delphi and the Mahindra ones are from Bosch. Guess Delphi is not upto scratch here.

Bosch has been able to localize their CRDI Fuel systems to Indian conditions, whereas Delphi hasnt been, they just import some and make some here, leading to sensitive parts.

so finally who is at fault?

TATA or Delphi or the car owner?

[wanderernomad]

Where are we headed in this thread? It might be anybody's fault but its the car owner who pays.

Well as per my discussion with a senior engineer , Bosch CR components are used in Multijet engines in Tata and Fiat vehicles and they also suffer from same fate due to adulterated fuel but Bosch has good service facilities for injector cleaning. An A.S.S can get the injector cleaned in same day from Bosch. An injector cleaning machine costs carores of rupees and Bosch has established service network at all major centres. Where as Delphi lacks this backup , Delphi just replaces injectors under warranty may be because the installed base is not as big as bosh the kind of investment required in service network is not put in.


Also with CRDI engines operating at lower pressure this problem is less severe so while older Scorpio CRDe fared quite well mHwack is more vulnerable.

Tata for selecting Delhi, Delphi for not establishing service network.

not true. i have an mHawk & no such issues so far. there are many mHawk owners in this forum & nobody has faced engine issues as far as i know.

and the car owner suffers...

I own an Indigo LX ( Not XL ) which has Dicor 1.4. Its been 3 years and I have not faced any issues with the engine - just thought of sharing my ownership experience for the engine in question.

Well there are so many DICOR owners who never suffered any issue, I even drove 300 Kms on pure kerosene and just irregular idling which went away after cleaning but does this prove that no one wil have any problem?

Similarly your individual experience and that of bunch of owners here is not a sample big enough, I am sure Bosch is spending carores of rupees for those machines not just for show-off but there are some engines which need injector cleaning.

[wanderernomad]

Same is the case with me, I own a 1.4 DICOR and no issues till now since Aug 07.

How about the CBU CRDe models like Range Rover, Merc, BMW, Volvo etc.. Shoudn't they also have the same issues with the fuel supply being imported completely along with the rest of the car?
