In order to answer consumers' questions about E10 bio-gasoline, Lao Dong Newspaper had an interview with Assoc. Prof. Dr. Tran Thi Thu Huong - Lecturer at the Faculty of Mechanical Engineering, Mechanical School, Hanoi University of Science and Technology.
Answering about whether using E10 gasoline causes fuel consumption or affects the compatibility and durability of the engine, Assoc. Prof. Dr. Tran Thi Thu Huong - Lecturer at the Faculty of Mechanical Engineering, Mechanical School, Hanoi University of Science and Technology - said that in theory, if calculated in the same unit of mass or volume, gasoline mixed with ethanol will have a lower energy level (thermal value) than traditional gasoline.
However, the blending ratio of E10 is only 10% (in 1 liter of gasoline, only 0.1 liters of ethanol is replaced). This is an extremely small ratio" - Assoc. Prof. Dr. Tran Thi Thu Huong analyzed.
If consumers feel "gasoline waste", this may depend on many other factors such as changes in routes, consumption habits, impacts from weather conditions or the use of air conditioning more in the hot season when traveling by car.
Switching between these types of gasoline does not significantly affect the operation of the vehicle. In case the vehicle is using traditional RON95 gasoline or E5 gasoline (gasoline mixed with 5% ethanol), users can switch to using E10 gasoline while the vehicle still operates normally.
According to Assoc. Prof. Dr. Tran Thi Thu Huong, in theory, if the fuel and blending ratio both ensure quality standards, switching from E5 to E10 can even help the engine operate more stably in suitable conditions.
The essence of ethanol is an additive that helps increase the octane index (anti-detonation index) of gasoline. With E10 gasoline, the anti-detonation index is much better, helping the car operate more smoothly and has the ability to generate greater power due to being able to withstand a higher compression ratio" - Assoc. Prof. Dr. Tran Thi Thu Huong informed.
