What is the benefit of E5 petrol - 'A replacement'?

Find out what benefits the "replacement" E5 will dominate when A92 gasoline is removed.

The difference of A92 petrol and A95 petrol

Gasoline is one of the finished products of petroleum distillation, used as a fuel, fuel for vehicles with internal combustion engines, or some items such as lighters, fireplaces .

The gasoline that we are using is finished gasoline with certain quality indicators, suitable for each type of engine. One of the criteria to distinguish is octane index - expression of anti-knocking properties of gasoline.

The higher the octane index, the higher the anti-knocking properties. This is also the meaning of the number in the name of gasoline: gasoline A92 (or RON 92) has an octane value of 92. Similarly, gasoline A95 (or RON 95) has an octane rating of 95.

The use of gasoline A92 or A95 is closely related to the compression ratio of internal combustion engines. Vehicles with engine compression ratios below 9/1 (usually digital vehicles like Honda Dream, Wave, Jupiter .) need to use A92 gasoline, while automatic vehicles (also called scooters) have compression ratio above 9.5 / 1 so it is often used with A95 gasoline.

The low compression ratio of high octane gasoline will prevent the gasoline from burning completely, causing fuel loss , reduced power, and causing sedimentation to cause the machine to fail.

In contrast, high compression ratio cars using A92 gasoline can cause detonation - gasoline burns before the spark plug ignites, causing energy loss, causing a heater, reducing performance, which is very harmful to the engine. .

Eliminate A92 gasoline and E5 biological 'substitute'

A92 petrol or A95 gasoline is essentially petroleum , which is derived from fossil fuels . Fossil fuels contain high levels of carbon and hydrocarbons - formed by anaerobic decomposition of dead organisms buried more than 300 million years ago. Products made after burning fuels include CO2 and CO - gases that are very harmful to the environment.

On the other hand, E5 gasoline is A92 gasoline mixed with 5% ethanol with 99.5% concentration.Ethanol in gasoline is prepared from compounds derived from plants and animals, such as fat, cereals, agricultural waste (straw, straw) .

According to studies, E5 bio-petrol when burning has a much lower level of toxic emissions than conventional fossil fuels.

Experimental results show that, thanks to the higher oxygen content of common gasoline, the internal combustion process is more efficient, increasing engine power and reducing fuel consumption.

Biomass E5.

Regarding safety indicators , since octane in ethanol is higher than regular gasoline, the final octane of E95 gasoline will fall to 93-94.

This is beneficial when mainly vehicles in Vietnam have a higher compression ratio than 9/1. The use of A92 gasoline, whether more or less, also results in detonation, machine wear and reduced engine performance.

According to some experts, for vehicles with old-type engines (before 1993) - acids in bio-fuels can affect engine rubber, plastic, and polymer grades.

But with motor vehicles produced after 1993, this is almost impossible. The reason is because the engine's material, especially the fuel supply system, has been improved.

Therefore, the acid in gasoline cannot affect the engine. Moreover, during combustion, this gas does not cause any other side effects.

Does the quality of E5 gasoline in Vietnam ensure the general standard of the world?

E100 materials as well as RON 92 before being warehoused by independent inspection companies (such as PV EIC and QUATEST), check the quality of products and quality products according to the current TCVNs. .

After that, E5 gasoline was prepared at dispensing stations distributed in E5 petrol business areas. After preparation, E5 gasoline is assessed by QUATEST Regional Quality Measurement Standards Centers 1 and 3 and granted conformity certification according to QCVN 01: 2009 / BKHCN - National technical regulation on gasoline, fuel Diesel materials and Biofuels and E5 petrol products must meet the quality standards according to TCVN 8063: 2009 - Lead-free Gas phase 5% Ethanol Technical requirements.

Thus, before using E5 petrol products, it is strictly controlled in all stages to ensure E5 petrol quality reaches the general standard of E5 gasoline in the world.

After more than 1 year of gasoline use E5 in 8 provinces / cities does not occur any engine problems related to E5 gasoline

Some countries around the world have been using bio-gasoline for a long time. The US pioneered in making ethanol as an additive for gasoline, with E10 (10% alcohol) in 2005 or 2008 Thailand even used E10 and E20 (10 and 20% ethanol).

What is the fuel consumption level of E5 compared to A92?

Mixing ethanol increases the octane value and makes the fuel burn more thoroughly.

The major automobile manufacturers in the world are clearly stated in the Manual for using the compatibility of unleaded gasoline containing 10% or more denatured ethanol volume for engines and still ensure Fully guarantee warranty benefits for vehicle users.

Some major automakers such as General Motors, Ford, Daimler, Infinity, BMW, Lexus, Nissan, Subaru and Toyota also recommend using gasoline containing up to 10% ethanol to improve the performance of the car and reduce emissions, improve air quality.

Many countries around the world have used E20 to increase the efficiency of engines.

Therefore, fuel consumption level of E5 is better than that of A92 petrol.

The continuous conversion between E5 petrol and regular gasoline does not affect the car engine

There are no technical problems with engines that use both E5 and traditional gasoline because in fact E5 bio-petrol is produced on the basis of putting ethanol into traditional gasoline. E5 gasoline is prepared from 95% A92 gasoline and 5% anhydrous ethanol. These materials are quality inspected by Quality Measurement Standards Centers before being warehoused and up to Vietnamese standards.

E5 bio-fuel with the upcoming Ethanol additive will completely replace A92 gasoline.

Currently, there have been studies proving that E5 petrol has absolutely no change in quality over a period of 6 months , so vehicles cannot operate regularly for a period of less than 6 months. E5 gasoline without fear of affecting the engine.

Is E5 petrol after a long time of storage?

The characteristic of alcohol is hydrated, especially the weather in northern Vietnam in the months with much water vapor in the air can create a risk for hydrated E5.

However, this is practically not happening because alcohol used to make gasoline is an alcohol with an alcohol content of 99.95%, which is almost to a snow level of 100% of alcohol, so it cannot be The water in the alcohol is fine, so E5 gasoline also cannot have water in it.

Therefore, we are completely assured of the possibility of E5 gasoline being hydrated.

E5 petrol is cheaper than A92 petrol

E5 gasoline has many advantages over A92 petrol, why E5 gasoline is cheaper than A92 petrol.

The reason is because the State is supporting consumers and gasoline trading companies. Specifically: The State is supporting E5 users at VND500 / liter by setting up a price stabilization fund lower than A95 and A92 gasoline and providing support of VND250 / lit for petrol business hubs to ensure profitability when blending mineral gasoline with E100 fuel.

Interim

In the context of depleting oil resources and devastating natural environment, the use of bio-fuel is a necessary trend.

As predicted by many experts, bio-gasoline will become the main fuel source to replace fossil fuels in the near future.
