Vietnam Accelerates E10 Gasoline Rollout to April 30
Translated from Vietnamese, summarized and contextualized by DistantNews.
TLDR
- Vietnam will accelerate the nationwide adoption of E10 gasoline, a blend of 10% ethanol and 90% mineral gasoline, by one month to April 30.
- Experts state E10 combustion is cleaner and more efficient, potentially improving engine performance and fuel economy while reducing harmful emissions like carbon monoxide.
- Despite lower heat value, E10's overall impact on engine durability and fuel consumption is comparable to mineral gasoline, making it suitable for existing vehicles.
As Vietnam pushes forward with its green energy transition, the Ministry of Industry and Trade has announced an accelerated timeline for the nationwide rollout of E10 gasoline, now set for April 30. This move, a month ahead of the original schedule, underscores the nation's commitment to cleaner fuel alternatives and environmental protection.
Ethanol contains oxygen, which helps the combustion process in the engine to be more complete and cleaner. As a result, the combustion efficiency is improved, contributing to enhancing the engine's operating efficiency.
Experts like PGS.TS Phạm Hữu Tuyến from Hanoi University of Science and Technology explain that E10, a blend of 10% ethanol and 90% mineral gasoline, offers significant environmental benefits. The ethanol component introduces oxygen, leading to more complete and cleaner combustion within engines. This not only enhances engine efficiency and potentially improves fuel economy but also substantially reduces harmful emissions, including carbon monoxide and unburned hydrocarbons. These improvements are crucial for Vietnam as it grapples with air quality challenges in its urban centers.
The difference in heat value is not large (only about a few percent) and is compensated by a more efficient combustion process in the engine.
Concerns about ethanol's lower heat value potentially impacting fuel energy and increasing consumption are largely allayed by research. Tuyến clarifies that the difference in heat value is minimal and is offset by the more efficient combustion process. Real-world studies and tests indicate that E10's performance in terms of engine power and fuel consumption is comparable to traditional gasoline, with some cases even showing improvements. This assurance is vital for consumer confidence and the smooth adoption of the new fuel standard.
In reality, this fuel does not cause negative impacts on engine durability and is completely suitable for existing vehicles.
Furthermore, the integration of E10 aligns with Vietnam's broader strategy for developing biofuels, building upon the earlier introduction of E5 gasoline in 2018. TS Đào Duy Anh from the Ministry of Industry and Trade highlights the importance of continuously updating fuel standards to match evolving engine technologies, such as the upcoming Euro 5 emission standards for new vehicles in 2025. The ministry's proactive approach in addressing challenges across the fuel supply chain, from production to distribution, coupled with robust public communication campaigns, is essential for a successful transition. This initiative reflects Vietnam's dedication to sustainable development and its proactive stance in adopting environmentally friendly technologies.
The engine technology is constantly being improved, leading to changes in technical standards for fuel over time.
