Phil. Diesel -> not CRDi ready?

[wowiesy]

with all the opinions i'm reading about our current local diesel not being fit for CRDi technology.. sana we can do some sort of survey here:

1. what type / year / make model of vehicle with CRD engine? (isuzu trooper? dmax? hilux?)
2. how old are your vehicles
3. have you experienced troubles with your engine and if so ano ang nature ng sira? anything engine related although maaaring remotely connected with the quality of diesel we have... malay natin di ba, pinagtatakpan lang ng mga service centers yung fact na diesel talaga natin ang problem...

i just want to prove or disprove na yung diesel natin ay fit / unfit for CRD engines..

[KCboy]

i think the 1st local crdi to be made available was the trooper 4jx1, dami ko na kilala including mine ha, nasira yung crdi namin.

now ive talked to the wheels personnel and sabi nila, yung rexton n sorrento na crdi will suffer the same fate kasi nga bulok ang diesel natin. cguro in a year or 2, they'll start stacking up on the injectors which is usually the culprit in crdi engines dto sa pinas.

i think sa x5 ganun din.

[av8or5]

excuse me for my ignorance..but can you refresh me and maybe the others what crdi stands for and it's purpose on a diesel engine.

CRDi -> Common Rail Direct injection

correct me if am wrong

[nugundam93]

yup, that's what it stands for.

it's basically a way to deliver diesel through high-pressure injectors on a common rail/line

With today's diesel prices, the fuel giants should, at least, add some quality to our diesel fuel! Do they think every diesel vehicle in the RP is a jeepney? Are they that stooopid?

Maybe not, but the government does think that way. I.e.:
Jeepney drivers/operators = voters
CRDi owners = voters
Jeepney drivers/operators > CRDi owners.

imo, most of the problems faced by diesel users here have mostly to do with water contamination. i don't think that sulfur content is the main culprit of the perceived dirty diesel. it think the problem lies in the combination of water and fuel that is combusted together.

imagine 50 cc of water that infiltrated the fuel tank. the 50cc of water may have come from many avenues. the condensation inside the fuel tank that naturally happens everytime we park our cars for the night; the humid atmospheric air that enters the fuel tank everytime we open the fuel cap; water pumped along with the fuel from the service station. imagine that 50cc of water sloshing about in 40 liters of diesel inside the fuel tank when the vehicle is in motion. that translates into a lot of dissolved water in the diesel.

just think of it this way: kunwari you have a wok of very hot oil. if you sprinkle a little water on it di ba umuusok at tumitilamsik? that happens because the small drop of water vaporizes instantly because of the heat. the small drop water expands suddenly and converts into a huge amount of steam. imagine that reaction concentrated in the nozzle tips of the injection system and repeated many times over. eventually, the tolerances go way off, fuel is not combusted properly, smoke belching occurs and problems become imminent.

FYI, a combination of water and fuel combusting isn't possible because water (vapor) is a byproduct of combustion. The water simply won't burn because it can't. If the amount of water isn't large enough to displace enough fuel and/or air, the combustion will still take place, but it'll be a smaller fire.

What water does affect is the properties of the fuel itself (lubricity, boiling point, freezing point, corrosiveness et. al.). The fuel was designed to have specific properties that will work best in a diesel fuel system/engine, and water contamination changes those properties. If there's enough water to change the fuel enough, your fuel will become "out of spec" and will start damaging your fuel system. In countries where they have winter, fuel in the summer is different from fuel in the winter.

P.S. the same also applies to your engine's cooling system. Theoretically, water is still the best coolant if you're only talking about cooling. But if you don't want your coolant to rust out your radiator, or freeze in the winter, et al. you add coolant/antifreeze to change the water's properties.

Yes its true may refinery dto ang Petron & Shell sa Pinas (the latter is in Batangas). and i'm pretty sure they are operating that will rival international standards. so the shady part is how are those fuel transferred to distributors and how clean are the tanks of those retailers.

Ditto.

tanong lang uli...

ano diff nung CRDi sa mga injection system ng for example sa Frontier?

[KCboy]

crdi does not have an injection pump. direct na. kaya dapat less black smoke but we have shitty diesels so black talaga.

[diesoline]

kcboy: pls share naman in detail what was the 4jx1's problem in your trooper and the others na nasiraan din. or if you have posted it na before, paki share na lang yung thread. tnx.

[KCboy]

sa trooper, the injectors just get clogged, thru time, u feel ur engine getting weaker and stalls sometimes until it just doesn't want to start or just dies on you while running, for me ayaw na magstart. a couple of my friends, namatayan, had to get their troopers towed pa. sa mga hi end vehicles like x5, siguro mamatay o maaffected pa yung ibang parts. sama talaga diesel natin dito,

KCboy, so how do get it fixed? does it entail injector replacement or could it be cleaned and recalibrated later? did you follow maintenance schedule of filter replacement religiously? how about in the other threads i've heard of suggesting doubling the filter - do you think it would work?. tnx for sharing info.

hmm.. ano kaya ang plano ng mga dealers here.. 2 years is within the warranty period pa ah.. tapos ganyan ang mangyayari... if and when this behavior exhibits itself after the warranty period.. may lusot na sila.. pero pag within... problem nila to..

considering na ang lakas ng benta ng innova at napakarami ay diesel ang kinukuha... ano kaya ang plano at strategy ng toyota about this issue?

[diesoline]

how many kms have you travelled when those symptoms started coming out? this was around two years ago ba?

[Doc Diesel]

ang trick dyan e nasa filtration......have an extra fuel filter installed and regularly check it. and go to one regular gas station when filling up.

[KCboy]

24000kms nun when it first exhibited the symptoms, may ginawa p asila nun para gumanda but after a few months, bumalik ulit at wala na daw sa warranty so i had to pay 47000 p to replace the injectors, u can double the filters but it would just delay the inevitable, screwed up injectors. disposable daw yun so once its clogged, palit na.

[Doc Diesel]

it is true that when it gets clogged up, palit na kaagad yan pero it still boils down to how you maintain it.

my dad's vito is still running very strong with two filters installed. never pang nasira.....

if you would like to install an additional filter, look for RACOR.

imo too, it all up to prudent filter monitoring. the only difference (i think) between local diesel and europe's diesel is the sulfur content, europe's being lower. lower sulfur content means fewer diesel particulates. hence, if local diesel has more particulates, then fuel filter changes should be more frequent than what the vehicle's regular maintenance intervals recommend.

with my car being a grey market kia sedona crdi, it was impossible to get a fuel filter in the local parts stores. buti na lang tsikoteer totoybato was very kind enough to send me one direct from korea. due to the absence of local filter availability, i find doc diesel's solution of an additional fuel filter practical. baka mapapasyal ako sa betan, kahit malayo....

doc diesel: masikip na engine bay ko. mapagkasya pa kaya ni racor ang extra filter dito? the fuel filter is between the two blue caps in the middle left side of the photo.

[al_motor]

i remember once a mechanic in san juan told me that if you're running a CRDi vehicle, you should stick to one particular brand of diesel, I forget which one if it's Total or Shell.

My dad is running a European vehicle with a hi-performance diesel...he's using two fuel filters and monitoring those two filters on a regular basis. Though, he claims the sound of the engine has changed a bit since he bought the car. Km reading is above the indicated 24000 expected lifespan mentioned here.
