Tanong sa Mausok na Trooper

[4JX1]

In my experience, SeaOil (the one near the end of Shaw Blvd - almost to C5), I've been using it for 2years on Trooper '01. Emissions are cleaner and smells less irritating than major brands. With SeaOil i usually only get black smoke at the start of the day. After the engine warms up, I accelerate fast - smoke is dark for a while, but after that almost none or very little smoke.

Unfortunately, I had an early trip recently so i did a full tank of Shell nearby, now i get dirty smoke even after pushing the engine. Between the two gas stations and brands, I'm going back to SeaOil.

I'm even thinking of trying Bio-Diesel (using the Senbel and mixing to full tank), has anyone tried this on Trooper '01 with 4JX1 engine? Anyone know if this works ok or does it clog the injectors?

bakit kaya ang tooper ko sobrang usok kapag umaarangkada ako?
Ano kaya ang pwedeng gawin para mawala ito?
I have been reading threads about khaos, aerogas & Ego device... but it seems no positive feedback from real users...

Sir, insist to have the following components check by your dealer even if your Trooper is fairly new:
1. Oil Sump Strainer
2. Injector Sleeve Seals
3. Turbo
The reason for this is the recall that happen in UK for 4Jx1 engines. Here is one selected discussion regarding this matter:

I have the same problem before (trooper 2003). I even bought BD from Gary before....
My experience: mausok sobra if your car's milage is less than 15T... after my 15T check up... the car's engine improved and less smoke, its like having a new car... as of today my trooper is performing above my expectations (unlike when I got it brand new)

Someone told me that diesel engine, smoothen up after 12-15T Kms... Base on my experience, its true.

Now if your milage is above 15T... baka nga naman may problema yun kotse mo.

just my 2 cents

Pease let me emphasize that only a few 4Jx1 are covered by this recall but if your kilometerage is within the range specified by Sir Cta2 then for your peace of mind and to ensure long term durability and reliability of your engine you may want to have those components check by your trusted mechanic that has tech2 equipment to diagnose first generation CRDI engine. Your engine Sir is one of the most advance diesel engine among Japanese SUVs when it was first released in 1999. Imagine it took Toyota nearly six years to have an engine with similar power and torque but at the expense of fuel economy. 4Jx1 on the other hand, manage to provide power and torque with fuel economy unequaled even by the latest diesel engine from its Japanese SUV competitor.

Guys, question lang.... pwede na ba ang biodiesel sa 4jx1-tc na trooper? last time I was reading di daw recommended due to the sensitive injectors ng trooper. Please advise. thanks!

[horexen]

Sir, marami na taga Tsikoters ang nakagamit ng biodiesel (cocodiesel). Tignan niyo dito: http://tsikot.yehey.com/forums/showt...3&page=9&pp=10 Binangit dito 2001 at 2003 model ng Trooper. Simula kasi 2000 model, 4JX1 na ang makina.

Kaya pueding-puede kayo mag biodiesel basta 5%-10% ang blend. Your Trooper's fuel tank capacity is 85 liters. So, 10% of that would be 8.5 liters. This means 8.5 liters of biodiesel for every 76.5 liters of fossil diesel. But why only 10%? Well, fossil diesel leave gunge (latak) on the vehicle's tank and fuel system. Biodiesel will dissolve this gunge. That is why, it is advisable for the first few weeks of using it that you should monitor your fuel filter and change it when needed. So, the end result of this low blend is a gradual cleaning of your fuel system.

Let us not forget that 4JX1 Trooper is also sold in Europe and since 1996 diesels sold there is blended with at least 5% biodiesel. You might want to read this article about biodiesel usage: http://journeytoforever.org/biodiesel_vehicle.html

the strength of the trooper engine is in its toughness n reliability esp sa truck(elf).

Ha? Truck(elf) gumagamit ng Isuzu Engine? sosyal ah
or are you saying that Isuzu engines in general are tough and reliable?

[kimpOy]

Kcboy talaga o...

basta trooper ang init agad ng dugo...

tama biodiesel mababawas yan...

[Isuzoom]

hello amigos! I have no more problem with my 4jx1-tc, I SOLD IT LAST WEEK...no more sakit sa ulo with my maintenance...my problem solved..

[garyq]

You can use BD sa 4JX1. It will NOT clog your injector. Dumi ang bumabara sa injectors. Since 99 when the 4JX1 was launched even in UK(and other EC countries) ginagamitan na nila ito ng B5. Do it logically, do an emission test before and after the BD so you can see and decide intelligently.

Thanks for that information, matagal na ako di nakakalogin kaya medyo di na updated. hehe anyway thanks for that information.

try to remove catalitic converter kc dun naiipon ung carbon nung engine... meron pa dapat barahan para ma by pass ung isang sensor tapos d na masyado mag carbon pati ung throttle ala na masyado carbon.. then makita ninyo improvement ng trooper balik dati lakas pati injector d na masirap....pag dinala ninyo sa casa d nila gawin un..... trooper namin sakin din ulo b4 pero once gawa ko un naging ok n sya

[OTEP]

So removing the catalytic converter improves emissions?

[notarius]

On the advice of Isuzu at the time of purchase, after each week's use, while idling, I rev the Trooper between 3000 and 3500 rpm to purge the catalyctic converter of accumulated soot. This weekly regimen, together with B2 fuel keeps me as a satisfied owner of a 2003 Isuzu Trooper.

[mechanix]

pasado naman sa emision test saka ala naman cya masyado usok not like b4 may catalitic converter sobra usok talaga.... try and see may good improvement ung trooper ninyo

[OTEP]

But the pollutants scrubbed by the cat are not measured by our outdated local test equipment.

Even in the U.S. and Europe, may acceptable levels pa din ng 'black' smoke for diesels so long as the other (usually odorless and colorless) pollutants are scrubbed out.

Guys,

Diesel engines in general emit a lot less carbon dioxide and almost zero carbon monoxide especially those with turbo as compared with modern gasoline engine. This is because diesel engines are lean burners. The fuel to air ratio may be as high as 1 to 100. So, most carbons oxidize completely.

Unfortunately, the very high compression ratio in diesel engine cause nitrogen to oxidize. Producing a lot of nitrogen oxide. The fossil diesel fuel is a complex molecule. It is denser and heavier than gasoline. During combustion it leaves a lot of residue technically known as particulate. The sulfur in the fuel also oxidizes producing sulfur dioxide which eventually becomes sulfuric acid.

The main function of catalytic converters is to transform carbon monoxide into carbon dioxide. There are still no cheap and practical technology for reducing the nitrogen oxide and particulates.
