EURO 2 and EURO 4, does it matter

[pctechphcom]

The New ISUZU DMAX 3.0 still uses EURO 2 does it matter?
forgot to mention CRDI din ang DMAX

From a functionality standpoint, Euro 2 or Euro 4 fuel will work exactly the same on a Euro 2 engine.

Euro 4 engines will need Euro 4 fuels. The reduced sulfur content from Euro 4 fuels can extend the life and efficiency of the tailpipe emissions systems that's present on Euro 4 engines.

To summarize:
Euro 2 engines can use Euro 2 and up fuels
Euro 4 engines can use Euro 4 and up fuels

Sulfur in diesel is the counterpart of lead in gasoline. It raises the cetane level & acts as a lube for the valves. It's the old, old diesel engines that are affected.

Sir when you say old diesel engine, how old? Im have my eyes on the just released Isuzu mux 3.0, they say it's new, but then I've read that it's an old engine (4jj1) fitted with VGS. And Isuzu Phils. says that it's not yet Euro 4 compliant. Should I be concerned?

Sulfur is NOT added to Diesel fuel. It's intrinsically part of crude oil as it is extracted from the ground. To adhere to Euro standards, sulfur is selectively removed, along with other undesirables by distillation and other methods.

Since more than a decade ago, sulfur is no longer needed for lubrication. And again, as specified by the Euro standard, lubricity is retained by the use of additives mixed in during the refining process. So as dictated again by the standard, whether it's Euro 2 (regular Sulfur) or Euro 4 (low sulfur) fuel, it will have the same lubricity.

So yes, Euro 4 fuel CAN be used on Euro 4, Euro 2 or older engines but NOT vice versa. Euro 4 engines should ONLY use Euro 4 or higher fuels.

how about the government saying na dapat all car makers should be euro 4 by January 2016, so I wonder why Isuzu still uses EURO 2 on their dmax 2016 model which I really like(have me worried since I am planning to get one on 1st or 2nd quarter next year)

will using euro 4 fuel affect the durability of euro 2 engine?

Last I've heard is that car makers are asking for more time for them to transition to Euro 4. I'm no expert but it's got something to do with the required adjustments in their manufacturing facilities, process and parts changes, logistics, and possibly some re-engineering.

Short answer: No.

Long answer: What makes an engine Euro-compliant pretty much depends on how much NOX, CO, CO2, HC, and particulate matter it's spewing out. The thing is, all these can be readily eliminated using a number of emissions systems in vehicles:
EGR
PCV
EVAP canisters/purge valve
Catalytic converter
Diesel Particulate Filter (DPF)
Selective Catalytic Reduction (SCR)
Diesel Exhaust Fluid (DEF)
O2 sensors
etc.

Car manufacturers, in their goal to meet Euro standards would need to use one or a combination of these emissions 'gizmos' to deal with the pollutants. The higher the Euro level, the car would typically need more of these systems installed. And for the most part, these things work wonders in cleaning up exhaust emissions.... that is assuming that these systems are operating properly.

Now where does sulfur come in? Well sulfur, like lead, are known to foul up exhaust emissions systems, reducing their efficiency or even rendering them useless.

So, reducing sulfur is key at reducing ALL other exhaust pollutants. If you reduce sulfur in fuels, these emissions systems will work more efficiently at reducing CO, CO2, HC, PM (etc.) emissions.

By that logic, if you use fuel with significant amounts of sulfur (or you ignorantly add sulfur to fuel for whatever reasons), sulfuric dioxide (by-product of burnt sulfur) will eventually reduce the life of some of the emissions systems and your car will end up spewing more of the other pollutants.

It doesn't matter only useless info that clutters your brain

What does adding 2T to your diesel do? Does it add sulfur content to the diesel?

Haba na ng thread sir about sa 2T. Andun na lahat ng discussion.

Euro4 rated engine can take only same level or better grade fuel (euro4 or euro5). Feeding lesser grade fuel like euro2 will have adverse effect on a euro4 engine

So beware of your engine rating

Not really going to be a problem with the engine, per se. Rather, lower grade fuel messes up the exhaust emissions system.

Agree. Well a bit as well to the fuel system, will fouled up quicker ang mga fuel nozzle. All others wala significant effect.

more on the dpf, mas madali ma-clogged up. nakakahiya pag binirit mo tapos nag-recycle siya

[potpot2]

So mas ok pala bumili ng euro 2 na engine kasi backward co pati le and at the same time future proof din, while euro 4 engine hindi bacward compatible? Tama po ba?

It's just that Euro 4 engines are better for the environment. There's no more backward compatibility issues now as most, if not all fuels available, are already Euro 4.

Technically yes

In addition, its more practical to get a euro2 engine because its cheaper than euro4

So considering the market, buying 2nd hand or old stock cars which are predominantly euro2 engines will be fine if you feed it euro4 fuel which is prevalent now adays

Feeding euro4 engine with euro2 fuel is a remote possibility now simply because euro4 is the mandate

That's also the reason why the govt can afford to mandate an upgrade in fuel grade without affecting the current car ownership
