Petrolimex Deputy Director General Nguyen Quang Dung said: “The trade of diesel level V instead of level IV in line with the Decision 49 is Petrolimex’s efforts to serve consumers with products of highest quality, making an active contribution to environmental protection. This demonstrates Petrolimex’s business strategy “Competition through product quality and professional services”. To that end, apart from supplying high quality products such as diesel level V, RON 95 petrol level IV since early 2017, Petrolimex has invested into developing the infrastructure system with advanced warehouses and depots, applying IT-based automated management software including ERP, Egas,Vapour Recovery System,petrol payment using ATM cards, etc.”.

Besides the sale of diesel 0.001S-V as of January 1, 2018, Petrolimex has also began selling E5 RON 92 bio-fuel since December 15, 2017, closely following the State roadmap to stop trading mineral petrol RON 92 from January 1, 2018.

Basic information about diesel 0.001S-V (EURO5)

Name of the fuel: Diesel 0.001S-V (EURO5); or DO 0.001S-V in short

The sulfur content index in comparison with diesel of other levels

Advantages of using DO 0.001S – V

(1) Increased durability and efficiency of engine

– Due to low sulfur content, the use of diesel 0.001S-V will minimise the damage to engine, in addition to diesel-powered engines of exhaust emission standard V, diesel 0.001S-V is fully usable for diesel-powered engines of exhaust emission standards II, III and IV.

– Diesel engines are produced in accordance with exhaust emission standards IV and V, have modern structure and high accuracy, and are equipped with exhaust gas recirculation (for complete combustion) and a catalytic system treating exhaust gas before it is discharged into the environment. Therefore, diesel engines produced in accordance with exhaust emission standards IV and V can only use diesel fuel with equivalent emission standards to ensure the durability and operation of engine, and cannot use other types of diesel fuel at lower emission standards.

– The use of diesel fuel with low emission standard for diesel engines that meet the exhaust emission standards IV or V can cause negative effects such as corrosion, reduced engine life, clogging and poisoning catalytic converter.

– Diesel fuel 0.001S-V has a suitable Cetane rating, enabling the efficiency of diesel engines whilst improving engine’s performance.

(2) Safety for users

Diesel 0.001S-V is safer for contact users and those directly contact with the fuel as the Polyaromatic hydrocarbons (PAH) content is controlled at max 11%, minimising the impact of this component on users/those with direct contact.

(3) Environmental protection

– Since the sulfur content in diesel 0.001S-V is limitted to a very low level (10 ppm S), the sulfur oxide SOx emissions (Sulfur oxide emission is a polluting exhaust gas from the burning of sulfur compound in diesel engine) are much lower than the use of other diesel fuels with lower exhaust gas emission standards.

– Besides SOx, the use of diesel 0.001S-V also makes considerable contribution to reducing exhaust gas discharged from engine such as hydrocarbons (HC), nitrogen oxides (NOx), particulate matter (PM), etc. According to the statistics of European emission standards on the website https://en.wikipedia.org:

• Emission standards for passenger cars, the HC, NOx, PM emissions when using diesel 0.001S-V are defined as follows:

+ NOx emission: reducing 64% from 0.5 (g/km) to 0.18 (g/km) as compared to the use of diesel 0.035S-III.

+ NOx + HC emissions: reducing 67% from 0.7 (g/km) to 0.23 (g/km) as compared to the use of diesel 0.05S-II.

+ PM dust particles: reducing 93% from 0.08 (g/km) to 0.005 (g/km) as compared to the use of diesel 0.05S-II.

• Emission standards for trucks (lorries) with tonnage above 1,760kg, the HC, NOx, PM emissions when using diesel 0.001S-V are defined as follows:

+ NOx emissions: reducing 64% from 0.78 (g/km) to 0.28 (g/km) as compared to diesel 0.035S-III.

+ NOx + HC emissions: reducing 71% from 1.2 (g/km) to 0.35 (g/km) as compared to diesel 0.05S-II.

+ PM dust particles: reducing 97% from 0.18 (g/km) to 0.005 (g/km) as compared to diesel 0.05S-II.

RECOMMENDATIONS:

– Diesel 0,001S-V (EURO 5) is usable for diesel engines with exhaust emission standards II, III, or IV.

– Diesel fuel at low level couldn’t be used for diesel engines with higher exhaust emission standards.
