What is Common Rail Diesel Technology?

[usokpower]

My folks just bought the new hilux because of its huge bed we can now put larger steel pipes and planks of wood. Our dissapointment AGAIN is walang bar sa likod pa install pa.

ANyway, back to the title what are the PROS & CONS of crdi?

Im sure may topic nang ganito and i dont have time to search.

I know crdi is electronic and ang ganda ng engine response its almost car like.

But Ive heard from my boss that crdi can be damaged at a certain time because our fuel quality here is poor. Is this true?

Do you know websites about crdi?

[KCboy]

yup, im staying away muna sa mga crdi units because of the poor quality diesels we have in the philippines. our 2000 4x4 4jx1 trooper gave out at 35000kms. barado na daw injectors. guess wat, 47000pesoses para palitan. i do hope that the newer vehicles are better. yung ibang tao nga sabi sa akin why mga x5 ok naman, i told them go ahead and drive ur x5 everyday for 2 years n they' ll see what i mean. yung mga diesel x5s naman d nila gamit arawaraw n mga low mileage so kahit 4 years na d pa umaabot ng 2ok kms karamihan.

sa madaling sabe, panget pala ang crdi tech...

[RedHorse]

can't help it... doon na talaga papunta ang diesel technology. Suot nyo na lang ang mga may hiwagang mayroon kayo pag bibili ng oto, ganon din naman di ba pag bibili ng bahay/lupa, opening a showroom, date ng bagong girlfriend etc...

[jojo_mouth2]

sa ibang bansa kc eh well refined ung mga diesel nila. i wonder if ang diesel dito sa pinas id ready for CRDi engines???

[quiksie]

hala lagot kala ko pa naman ayus ang crdi tech! patay ang mga starex and isuzu users!

[bilog]

actually CRDI is good and so far i havent read anything negative about the CRDI.

are the 4jx1 crdi engine? ang alam ko kasi sensitive lang talaga ang injectors ng isuzu specially the late model troopers.

[boybi]

yup. Isuzu's 4JX1 are CRDi engines.

ang pangit ay ang quality ng fuel dito sa pilipinas.

euro I lang ang implemented dito sa atin. kung euro IV standards na ang implemented, hanggang ppm na ang sukatan ng sulfur content ng diesel, hindi lang %.

[the_wildthing]

Pag ganon di na puwedeng tawaging "krudo" kasi hindi na crude... "refined" na.
Sorry couldn't help it. Hehe.

[usokpower]

I hope kaya ng crdi ng toyota ung diesel fuel natin. mukhang $$$$$$ pag tagal ah.

May client kami who happens to be a former employee of Shell. Sabi nya diesel fuel natin pang factory spec. mataas pa ang sulfur content

[mazdamazda]

that's why i posted before an article about diesel engines / fuels:

http://tsikot.yehey.com/forums/showthread.php?t=16358

sulfur content ng diesel fuel natin is currently at 0.05%. although malaki na rin ang improvement pero hindi pa rin sapat.

ang euro III, 350 ppm (part per million). while ang euro IV, 50 ppm ang requirement.

Pwede malaman san ka nag pagawa ng crdi mo?

[maop99]

e di pag tumaas pa ang quality ng diesel natin taas presyo din? Correct? patay nanaman tayo.....

i don't think there's a problem with crdi technology. as most of the guys have said, the issue is the poor quality of diesel in our country.

This problem was solved by toyota. Lets wait and see na lang. Yes diesel here in the philippines is dirty, but the 2ND generation d-4d that toyota put on the hilux will elimate the problem of clooging injectors. I heard lots of cases with that sa trooper.

Simple explanation lang why that won't happen to your hilux...

The d-4d that the new hilux has now is the first in the market with secong generation common-rail.

The 2nd generation common rail is the fuel rail wgich stores the highly pressurized fuel before dispersing to the injectors. With this, it won't clog because the pressure will be like trying to carry an adult elephant on your thumb. Thats how high the pressure is.

The second gen common rail also has a high pressure fuel pump....

another advantage is the 32 bit ecu. Its technology is advanced already and the ECU monitors the temperature, RPM and other factors to control the injection timing.

I hope with these, you will feel more at ease with you r purchase of the new hilux. ...sana you got it from me na lang. heheheeh!

Cheers

hindi ba ma-address ng biodiesel yung problema (fuel quality and CRDi clogging problem)?

i chanced upon this article in www.biodiesel.org. i'm not proclaiming that this is the ultimate solution... just sharing what i found to be interesting and related to this discussion...

NBB Welcomes DaimlerChrysler’s B5 Biodiesel-Powered Jeep Liberty in Missouri

DaimlerChrysler hopes to capitalize on the growing interest in biodiesel, along with a trend toward
renewed consumer interest in diesel passenger vehicles, with its introduction of the Jeep® Liberty
Common Rail Diesel (CRD) later this month. Each 2005 Jeep Liberty CRD leaving the factory will be
powered by B5 – a five percent blend of biodiesel. More than 40,000 consumers have already expressed
interest in Jeep Liberty's “clean running diesel.”
The National Biodiesel Board (NBB) members, convening for their annual board meeting in St. Louis this
week, were among the first in Missouri to test drive the much-anticipated Jeep Liberty CRD as
DaimlerChrysler hosted a Ride-and-Drive experience at the board meeting. St. Louis area members of
the Biodiesel Backers, an NBB Web club, also attended the event.
The Jeep Liberty diesel, the first diesel-powered mid-size SUV to be offered in the United States, will
achieve approximately 30 percent better fuel efficiency than Liberty's comparable 3.7-liter V-6 gasoline
engine. Diesel engines also reduce emissions of greenhouse gases by 20 percent compared with gasoline
engines.
(more)
“With biodiesel, we can increase these benefits even further,” said Chrysler Group President and CEO
Dieter Zetsche. Biodiesel reduces emissions of particulate matter, unburned hydrocarbons and carbon
monoxide compared to petroleum diesel. Biodiesel also significantly reduces emissions of lifecycle
carbon dioxide.

fixed my trooper sa isuzu makati. crdi is a great improvement the old diesel technology but our diesel here in the philippines really suck big time.

[totoybato]

kinakabahan ako sa mga post ninyo. I am bringing home dyan sa Pinas this year yung cariton kong Hyundai which is equipped with a 16 valve crdi engine. Sa experience ko kasi dito, parang gas powered yung sasakyan sa lakas ng hatak at sa bilis ng response pag nag accelerate ka kaya ko ito binili. Nakupo, pano na ito, napasubo ata ako, akala ko ba malinis na diesel dyan sa atin? :confused:
