New announcement about the cause of vehicle fire

Today (May 17), Ho Chi Minh City Department of Science and Technology organized a press conference to officially announce the cause of vehicle fire in the past time.

This is the research result that the Department has directed the Center for Research of Petrochemical Technology (RPTC), the Key Internal Combustion Engine Laboratory (Polytechnic University of Ho Chi Minh City) after the series. consecutive car fires occur.

According to Dr. Huynh Quyen, Research Center for Petrochemical Technology, the research team initially focused on researching motorbike engines. Previous studies have shown three groups of causes for vehicle fires such as the use of poor quality gasoline (mixed with methanol, ethanol) not technically correct; short-circuiting and objective and subjective factors by users. Now scientists are continuing to study and argue about the results achieved.

Of the three causes, the use of poor quality fuel such as gasoline mixed with methanol, low quality ethanol and improper techniques is believed to be the cause of gasoline leaks due to the fact that the pipeline system has been destroyed or Due to the high steam pressure, there are also cases where the user carelessly leaks. Gasoline leaks in contact with sufficient heat source generated by the source: machine operation, or friction of the brake system, or sparks generated by short circuit of the electric system in the vehicle (phenomenon This is explained by the fuse protection system no longer works or poor quality fuse) . According to the judgment, these are the factors that make up the ability to cause car fire.

Earlier, on April 26, Ministry of Science and Technology, Ministry of Industry and Trade, Ministry of Transport, Ministry of Public Security also had a press conference to announce the initial results of research on the cause of vehicle fire. At the meeting, Mr. Tran Van Vinh, Deputy Director General of the Directorate for Standards, Metrology and Quality, Ministry of Science and Technology also gave the initial results of research on fuel, fuel and fuel mixture. with addition of methanol and ethanol with concentrations below 30% cannot automatically ignite, does not cause vehicle and motor vehicle fire except in special cases of fuel leakage and exposure to large heat sources Over 400 degrees Celsius. On the other hand, gasoline fuel with high methanol and ethanol content causes aging of the fuel fuel pipeline, resulting in fuel leakage that creates a potentially explosive atmosphere when there is a high heat source, especially when available. Ignite the electric spark.

However, exchanging with PV on May 16, Mr. Vinh affirmed that the above-mentioned studies have not yet confirmed the exact fuel and oil is the main cause of car fire. Therefore more research is needed.
