Find the cause of a series of fire engines

While waiting for the final conclusion of the authorities, the incident of running motorcycles suddenly caught fire or exploded in the middle of the road; experts, scientists recommend, be cautious with the electric system, battery, gasoline in the motorbike.

While public opinion is not over, the authorities have yet to find out the cause of the Honda Dream motorbike exploding, causing a pregnant woman to die and make a seriously injured baby in Bac Ninh, noon 12 / 12 a Honda SH motorcycle caught fire on Kim Ma Street (Hanoi). Before that, in the afternoon of December 9, the Honda Air Blade motorbike carrying BKS 90H8 - 7458 also set itself on fire while circulating on Nguyen Trai Street (Thanh Xuan, Hanoi).

There is fire, there is gasoline as a fire engine

According to experts, for electric motorbikes, the burning of cars is not strange, just short-circuiting, fire that meets gasoline is a fire engine immediately. The joints lead to a non-enclosed gasoline or a leaked gasoline conductor that causes gasoline to leak out to high-voltage power. Battery, spark plugs when starting electric spark will cause fire or even in the process of circulation because the bumpy road makes metal devices that are not fixed tightly can collide with each other to generate sparks.

For old motorcycles, gas leaks are mostly caused by cracked pipes, cracked joints, tight joints; and the new cars are mainly bitten by rats, punctured with electric wires, fueled. With nearly 20 years of experience in repairing cars, Mr. Nguyen Duy Thanh, Duy Thanh Motorcycle Maintenance and Repair Center (Me Linh, Hanoi) affirmed that the new motorbikes run electronic fuel injection if they are punctured with gasoline wires. more dangerous because just the owner of the car turns the lock on the car, the gasoline will spray out in the form of fog, covering the engine. Just a small spark can quickly burn the car down within 10 minutes.

Mr. Do Van Nhat, Nhat Huyen Motorcycle Repair Center (Soc Son, Hanoi) said that the situation of self-improvement, installation of horns, lights, lights, floating batteries, non-genuine now is very universal. turn. This additional installation has changed the intensity, current capacity, standard voltage on the vehicle, resulting in overload, causing short-circuit and fire incidents at any time.

According to Associate Prof. Dr. Pham Van Nho, Department of Physics, University of Natural Sciences (VNU), there is gas leak and sparks will lead to vehicle fire. Burning in a closed environment will lead to explosion. The vehicle explosion in Bac Ninh may be due to a gas tank explosion.'It is necessary to wait for the results of the inspection by the competent authority to know the cause of the vehicle explosion. However, it must be affirmed that gas tank explosion is extremely rare. In a closed environment in a volume of 4, 5 liters like a gas tank, if it explodes its destructive power, it is as big as exploding a mine , 'Professor Nho said.

Consumers suffer

Expert, scientist recommends, be careful
important for electrical system, battery, gasoline .

The fire and explosion of motorbikes is unusual, but more unusual in the fact that the fire and explosion motorbikes are mostly new and recently purchased or under warranty and most of the same manufacturer. . This has caused doubts about vehicle quality from experts. Mr. Japan explained: 'If Chinese cars are burnt and blamed, it is blamed for low quality due to low prices, but in reality it shows that there is no Chinese motorbike that burns and explodes, but all of Honda firms, a few Yamaha's. I think the quality of motorbikes is definitely problematic. '

In this view, KS Nguyen Trung Thanh, Thai Nguyen University of Industrial Technology, said that in order to compete, firms compete to launch new models, sometimes a few models. Production is not up to demand, so quality is not guaranteed.

In Vietnam, mainly the oral training, the wrong wiring causes short-circuiting, which can lead to fire and explosion of dangerous lives to consumers. While the cause of motorcycle fire and explosion has not been clarified, according to Assoc. Pham Van Nho, consumers should be more cautious when using motorcycles. Please check the car carefully before departure, make sure the gasoline is not leaking, no straw, paper, paper or other flammable objects under the car. Regularly maintain to check and overcome errors of wires, spark plugs, carburetors, fuel tanks . at reputable establishments and do not add electrical equipment on the vehicle.
