How Do We Pinoys Like Our Diesel?

[rst619]

good question. i'm interested in knowing the answer as well. it's a bit late but i just found out that seoil is already offering euro v compliant diesel (see here: http://www.seaoil.com.ph/index.php/Products/Biodiesel), this is good. But what they offer is biodiesel. Bottom line is, its a cleaner diesel, but it has biodiesel blend, is it safe to use on modern CRDIs and D4Ds?

Diba most CRDI's and D4Ds naman kaya up to 5% blend ng biodiesel? so wala sigurong problema.

Ang tanong ko lang is talaga nga bang Euro V ang base diesel ng Seaoil? kasi ibig sabihin nun low sulphur na, tapos kelangan may additive siya for lubricity para sa mga pre-2007 diesel engines.

BTW Unioil daw is 2% blend na. ano ba mas maganda sa modern engines?

Dear Sirs:

The Euro XX standards referred to are strictly speaking, EMISSION or Pollution Control standards, not fuel specification standards. To be more precise they do NOT cover basic fuel properties like lubricity, cloud-point, pour-point, gel-point, maximum allowable water content, energy content, etc.

What the Euro XX standards refer to are merely the maximum permitted emissions (like CO - carbon monoxide, HC - unburned hydrocarbons, NOx - Nitrogen Oxides, S - Sulfur Content and PM - Particulate matter), for various classes of vehicles like passenger cars, light commercial vehicles (<1305 kg, <1760 kg, <3500 kg), and lorries and trucks.

For the correct DIESEL Fuel Properties one should refer to the ASTM (American Society for Testing Materials) International ASTM-D975 standard for automotive diesel fuels. There all of the currently required properties of diesel as an automotive fuel are specified.

Do NOT worry about biodiesel or biodiesel blends as long as they conform to the relavant standard, they should be okay - and I will quote this -

" the ASTM International Biodiesel standards include:

• D6751-08 Specification for Biodeisel Fuel Blend Stock (B100) for Middle Distillate Fuels
• D975-08a Specification for Diesel Fuel Oils (on and off-road applications)
• D396-08b Specification for Fuel Oils (home heating and boiler applications)
• D7467-08 Specification for Diesel Fuel Oil, Biodiesel Blend (B6 to B20)

The standards ensure that the following important factors in the fuel production process are satisfied:

• Acid value
• Complete reaction.
• Removal of glycerin.
• Removal of catalyst.
• Removal of alcohol.
• Absence of free fatty acids.
• Low sulfur content.
• Cold Filter Plugging point
• Cloud Point

"
As you can see the standard requires the removal of ALL alcohol, glycerin, catalyst, FFA's and low sulfur - even for 100% pure biodiesel, let alone biodiesel + petroleum diesel blends.

matipid nga naman talaga ang diesel kaya gusto ng karamihan ng pinoy dahil na rin sa presyo nito.

medyo OT:

ang problema lang kasi kung bakit nagiging mausok ang diesel dahil karamihan sa atin ay hindi maalaga dahil na rin hindi nasusunod ang proper maintainance nito at hindi lang yan kung kaya't mauusok rin ng mga diesel dito sa atin dahil ang timplada ng diesel sa atin dito sa pinas paano naman kasi hinahaluan ito ng extenders para nga naman dumami ang diesel para nang sa ganon ay dumoble ang kita ng mga ang mga nagbebenta nito.

bakit ko nasabi ito? dahil ako mismo ay nakasubok na ng diesel fuel na galing japan noong umorder ako ng makinang diesel kaibigan ko na nagpaparating ng japan surplus para sa pinapa-assemble kong XLT na AUV, nung dumating na ang makina na inaantay ko binigyan pa ako ng libreng dalawang container na krudo mula sa surplus na tangke ng isuzu GIGA paano may laman din kasama.

syempre tuwang-tuwa ako dahil maski papaano sabi ko sa sarili ko "ayos naka-libre ako ng krudo na galing japan", ang napansin ko sa kulay ng krudo halos wala syang kulay at kung makikita mo aakalain mong kerosene ito at isa pa iba ang amoy ng krudo nya hindi mabaho parang ang amoy nya may pagkahawig sa kerosene, tinawagan ko agad ang kaibigan ko at tinanong ko "pre bakit kakaiba ang amoy ng krudo may halo ba ito?" ang sabi naman nya ay wala kasi maganda ang quality ng diesel fuel ng japan at isa pa nakita ko naman na galing sa surplus na tangke yun.

nung isalin ko sa XLT ko ang krudo na yun ang ganda ng tunog ng makina na inilagay ko XLT parang bagong makina at nung ni-rev ko ng matindi wala siyang usok kaya ginamit ko na ang krudong galing japan hanggang sa maubos, pero nung maglagay na ako ng krudo na binebenta dito unti-unting pumapanget na ang tunog ng makina ko at nagiging mausok na rin sya kaya sa obserbasyon ko na ang diesel natin ay may daya ang timpla, maski sa gasolina na nasubukan ko galing japan na inilagay ko sa XL corolla ko gumanda ang andar ng makina ko pero nung naubusan na ako at balik sa gasolina ng pinas ay balik na naman sa dati ang andar ng makina ko ok rin naman yun dating andar ng makina ko pero mas naging ok yun nagkarga ako ng gasolina na galing japan.

kaya ang medyo obserbasyon ko lang ay talagang may daya ang timpla ng fuel natin dito yun sinasabi nilang 93 at 95 octane hindi sya ganun ka-accurate

Dear Sir:

Japanese automotive diesels conform to the standards set for ultra low-sulphur diesel fuels and as such have been subjected to a more sophisticated and comprehensive refining process.

This is NOT possible in the Philippines because our refineries are all old and outmoded and are not (because of their relatively small size along with that of the market) considered economical to upgrade.

To put it simply, Japan is a wealthy and modern country and can refine its fuels to meet the highest standards. We are poor and do not have our own technology so we cannot do the same.

medyo ot lang...

yung biodiesel ba, may issue pag ginamit sa old school diesel engines like 4m40, td42, 4d56, and the likes?

[duskylim]

Dear Sir:

If made by a properly run and equipped facility there is no reason why biodiesel should not work well with the older engines. In fact the older engines are much more tolerant of bad fuels than the new ones.

Why? Well there are several reasons:

First, the new engines all use the common-rail fuel injection systems, which involves the use of a very high-pressure fuel pump to raise the injection pressure to 25 000 to 30 000 psi in the most modern engines.

These pumps have very close tolerances and are easily damaged by the smallest particles or impurities or by a reduction in their lubrication.

It is important to realize that the modern diesel fuel pump is lubricated not just by the engine oil but also by the diesel fuel itself, problems with the fuel will cause problems with the pump.

Any impurities that reduce the diesel fuel's lubricity results in a damaged fuel pump - and as any new car owner who was unfortunate enough to experience it, replacement pumps are frighteningly expensive.

The older injection pumps operate at much lower pressures (around 1500 to 2500 psi) and have wider tolerances allowing them to withstand minor impurities and diesel fuels of varying lubricity.

Second control of these engines now resembles that of modern fuel-injected gasoline engines with numerous sensors feeding a computer-controlled injection system.

These systems are much more accurate but much more sensitive to fuel qualities than the older systems.

The older engines can even be run on mixtures of diesel fuel and SVO Straight Vegetable Oil (non-refined cooking oil), or even WVO Waste Vegetable Oil (usually collected from restaurants) - try that on your modern diesel!

There are many forums and websites that focus on this topic.

sir Dusky any info kung alin ang best diesel fuel dito sa atin? TIA

[badkuk]

and that may be the reason why diesel cars/trucks here are "dirty".

if only the biodiesel thing really goes full swing, that would solve the emissions issue real quick. no more Euro I/II/IV/V standards, just clean biodiesel.

[scharnhorst]

If diesel prices were to go up, then commodities transported overland would certainly experience price hikes as well. Also applies to public transportation.

kawawa ang common pinoy.

Right now it's not particularly feasible to insist making ULSD or B100 mandatory here in the country.
