I think for smoke issue with many commercial vehicles is mainly due to poor maintenance. I don't see smoke issues with many diesel cars in Singapore.

Fyi, a poorly maintained petrol car produces smoke as well.

much much lesser then diesel.

its open fact that diesel engine higher emissions of NOx and much higher emissions of particulate matter.

which is smoke.

dpf system store the particulate matter away, but when it work to clean the system, it produce white smoke, and it smell really bad.

In SG where Humidity is nearly 90~100% 365, NOx dissolved to found acid and before reach our system, turn to Nitrate liao.

Hence, our NEA number they ownself publish is NSEW is ZERO lor, there is NO NOx in SG wor........

Then what's the problem here... Knn.. it's all about 💰

They just issue a directive through JTC to stop Uber (last week) and private car (this week) from pumping those 95cts Diesel lor.  Greed level 999 !!

11 Reasons Why Diesel Trumps Gasoline

source: https://www.drivingline.com/articles/11-reasons-why-diesel-trumps-gasoline/

Occasionally, we like to stir the automotive pot, and this one is sure to do it! It’s the age-old diesel vs. gas debate—and it’s guaranteed to get a few of you into a verbal throw down. While both forms of propulsion have their place, diesel tends to dominate when big jobs have to be tackled as efficiently and reliably as possible (hence its preferential use in the military, construction, transportation and railroad industries). On the racing scene, gasoline engines have long held the throne in most categories.

However, in recent years, diesel technology has advanced at a rapid pace, which has only promoted further versatility—namely in 3/4-ton and 1-ton trucks. No longer are these oil-burners limited to workday chores. It’s now common to spot an 8,000lb, diesel-powered Ford, GM or Ram tearing through the quarter-mile in 13, 12, 11 and even 10-second intervals. Diesels have also begun to draw large crowds at chassis dyno competitions and headline the biggest sled pulls in the country. Once upon a time, the Audi R10 TDI even infiltrated (and dominated) the esteemed Le Mans racing series.

So, with diesel excelling in so many key areas, is it the better engine choice? Judging by the title, it’s pretty clear which side yours truly plays for, but whose side are you on? Diesel or Gas?

1. High Compression = More Power & Better Efficiency

What do OEM manufacturers, aftermarket enthusiasts and all-out race teams do to increase power and efficiency in their gas engines? They up compression. Diesels range from roughly 16.5:1 to 19:1 vs. gasoline’s typical 9:1 to 10:1. This means higher cylinder pressures (hello torque), a cleaner in-cylinder burn and—being that diesels rely on compression ignition rather than spark—no worry of pre-ignition or detonation.

2. No Throttle Plate

Unlike a gasoline engine, a diesel doesn’t have a throttle plate (which should more appropriately be labeled a “restriction plate”). This means a diesel’s cylinders are packed completely full of air during every intake stroke, regardless of the driving or operating conditions. By contrast, the only time a gas engine breathes this well occurs under wide-open throttle instances. A lack of throttle (restriction) plate also means no pumping losses for the diesel engine. Did you know a gas engine expends as much as 40-percent of its total power output trying to overcome its own air (throttle) restriction?

3. Any-Purpose Engine

No other internal combustion engine is as versatile as a diesel. For instance, only a diesel-powered pickup can be used as an all-in-one work truck, tow rig, sled puller, drag racer and daily commuter and remain as reliable as it was the day it left the factory. There are thousands upon thousands of diesel trucks making 500hp (1,000 lb-ft) or more that serve all of the above functions, not to mention that four-wheel drive models offer year-round drivability and off-road capability. The allure of a diesel engine is its do-anything nature.

4. Better Ingredients

Because diesels feature high compression ratios, see high cylinder pressures and are typically turbocharged—they’re built with burlier parts to withstand all the stress. This means premium items like forged-steel connecting rods, four-bolt mains, six head bolts per cylinder, compacted graphite iron blocks... even bed plates make it into a lot of diesel engines. As well, nearly all heavy-duty diesel engines are gear-driven (no timing chains or belts).

5. Leaner Air-Fuel Ratio

When you run a gasoline engine too lean you kill its power potential, run the risk of overheating or worse, melting a piston. In an effort to cool down combustion, gas engines will dump extra fuel at wide-open throttle. The complete opposite is true of a diesel. Lean out the fuel and the engine runs cooler. Add fuel to the mix and combustion temps and exhaust gas temperature goes up. This is why diesels run a leaner air-fuel ratio than gas engines. In fact, some diesels utilize an air-fuel ratio as high as 90:1 or 100:1 at idle. Optimum gasoline air-fuel mixtures usually check in around 15:1, while most diesels operate at 18:1 or higher.

6. Better, Safer Fuel

Diesel fuel’s chemical makeup makes it at least 15-percent more energy dense than gasoline. On top of that, diesel fuel is oil-based, which essentially makes it a lubricant when introduced to cylinder walls. By contrast, gasoline is a solvent. Gasoline is also much more volatile than diesel (i.e. more explosive/flammable), which makes diesel much safer in the event of an accident.

7. They Aren’t Picky Eaters

Being that diesel is an oil-based fuel, it shouldn’t come as a surprise that virtually any oil-based alternative can be burned. We’ve seen diesel engines running on vegetable oil, grease, used engine oil and even automatic transmission fluid. But the diesel engine has always been capable of operating on alternative fuel sources. Case in point, the original diesel engine was designed to run on coal dust, but Rudolf Diesel subsequently found that it would also run (much more safely) on peanut oil.

8. Most Powerful

The most powerful engine in the world is diesel. Measuring approximately 90-feet long, 44-feet high and weighing some 2,300 tons, the Wartsila-Sulzer RTA96-C cranks out 109,000hp. The Finnish-designed, 14-cylinder, low-speed two-stroke diesel behemoth spins a maximum of 102 rpm, but generates as much as 80,080 KW of power—enough to power a moderately sized suburban town. Fitting for the world’s largest engine, the Wartsila-Sulzer RTA96-C is used to propel the largest ocean-going vessels in the world, such as 1,300-foot long, 70,000-ton cargo ships.

9. Big Torque at Low RPM

Thanks in part to the extreme cylinder pressures they see, most diesel engine’s produce their peak torque figure at or below 2,000 rpm. This not only makes diesel the ideal means of getting heavy loads up and moving quickly, but makes it easier for them to maintain speed while out on the highway. An abundance of low-rpm torque is also why 8,000lb diesel trucks can cut 1.5 to 1.8-second 60-foot times at the drag strip. While most gas power plants are just beginning to come to life between 3,000 and 4,000 rpm, a diesel is ready for the next gear. Living life at a lower rpm also lends itself to a diesel engine’s long-term durability.

10. A Mechanical Diesel is the Ultimate Doomsday Engine

Older, mechanically injected diesel engines are stupid simple and require virtually zero electronics to run. Once started, all a fully mechanical diesel needs to stay running is a steady supply of fuel. There is no need to worry about air, as once you fuel the engine the air will follow. If things ever go dark, you’ll find us driving something with a 12-valve 5.9L Cummins under the hood.

11. Diesel Makes the World Go Round

Frankly, if diesel isn’t superior to gasoline, why do the construction, trucking, shipping, railroad, aviation and mining industries rely on it almost exclusively? And why does every branch of the military depend on it? It’s because diesel is more efficient, powerful, reliable and versatile. With the power of diesel, you can travel farther, get more work done and even use an alternative fuel source if you have to.

So, still think gas is best? Or is electric now the future? Join the conversation in comments below.

 

 

Whole world already knows diesel is very dirty and cannot be made clean, except by cheating and doctoring tests.

It is only tolerated for industrial or heavy duty applications because of its specific favourable characteristics.

Why suddenly come out with this article even at a time when VW and the german makes have already started clearing out their diesel after decades of cheating? Can't see the writing on the wall?

On a side track, diesel high compression architecture is making a comeback.

When did, in recent times, Cnergy /Smart sell diesel at 95cts laaa ?

There is a really really really Zero Frill Diesel Station lor, they folded a key 95cts supplier, the next range is the 104cts ....... I have been driving with this type of fuel happily until this week lor ......

Sigh ........ too late.  They folded the 95cts one, one of SG largest 3-tier lor.

The most recent one on 19 @Jalan Tepong lor......

2 more branches one in Defu and one in some ulu place....... it is like driving in a desert and suddenly an Oasis for Diesel Car ...... ya ....... got sell AdBlue too..... Maybe still can buy Adblue ...... for those SCR car ......

Aiya, all along is media, ownself say ownself song one. As for VW, I never own one lor. 

As for pollution ....... Here are the facts from NEA hor, not some juicy 3rd Party App ...... As for the North South East West, you ownself find out hor..... It is Anytime like that one.....

BTW, are you those surveyed that SG need to spend 100B for Climate ?? ST SAID Majority of Singaporeans Surveyed is OK to PAY MORE to save Climate wor ?  Fake News ? Garment should include a Referendum in the coming Elections ASKING if WE are OK to Spend 100B (S$100,000,000,000.00 ..... it is that long) lor.  It is NOT a small sum hor.  Example, to build T5 we are paying alot for Airport Tax hor.

Thanks bro.

Looks lok kok 😂 but will pay them a visit to have a look see 🙂

Any comments on SPC diesel?

I personally siam their petrol, especially the RON 95 as it does feel more lethargy.

which part of Defu can share more?

im driving a diesel car, got it not cos of high mileage( i do about 15k or less per yr).

is bcos of the driving feel. tiak tiak sound cant hear once you close door. only people outside can hear(not that i care)

Oh ...... you are late.  They stop selling to Pte Car and PHV liao.

They SAID JTC don't allow them to sell to us wor.

Go give a try, maybe they change their mind.  Report here.

Need to register token $10.

haha, has been pumping smart energy / caltex all along, sometimes esso.

is their diesel euro5? my friend pumped euro2/3 diesel in msia and car really omit smoke alot ..and no power.

Er ...... all diesel selling in SG is Euro5 lor.  Have been happily pumping 80~104cts until they closed up.  Pumping Cnergy now, more ex 110cts.

Your friend driving a 3008/5008 ah, they said AD OK them to pump Euro2+ wor, it is about 10sen cheaper lor.  These car can tahan the high sulfur meh ?

C&C has to put in write I will only use Euro5 Diesel lor....
