Things come when we often drive directly cold car start, time is long, the car can always smell a smell of gasoline, in fact, this smell of gasoline is very dangerous, you are unlucky, there may be spontaneous combustion of the car, then spontaneous combustion occurs during the driving process, the harm can be imagined, it is not as simple as a simple traffic accident.
Under normal circumstances, it is normal to smell gasoline, it is a smell produced by gasoline that is not burning at the time of start-up, but sometimes it can not be careless, in case this is the smell caused by the failure? Let's analyze the reasons for the smell of gasoline now.
First point:
One of the situations is that the car gasoline may leak, if we smell a strong smell of gasoline while driving, we can't be sure where the cause is, we can get out of the car and check the exhaust pipe and the engine. If we find a pool of gasoline in the groove of the engine, then we need to deal with it in time, otherwise there will be unimaginable consequences or even nature.
The cause of the gasoline leakage is also very simple, mainly because the engine compartment part has some places that are metal, some places are rubber, and in the winter, the rubber part will harden, and the vibration of the engine will cause leakage after the interface between the metal tubing and the rubber tubing, which also leads to the occurrence of the engine routing situation.
Second point:
Many drivers will say the word "windgate", but where is this damper? The damper generally appears on the handlebar of a motorcycle and is similar to the function of a motorcycle handlebar. After we open the damper, the oil supply of the carburetor will be greatly improved, and once the oil supply is increased, the concentration of the mixture will also come up, then the spark plug will be particularly easy to ignite at this time, and the engine will be easier to start. However, the increase in fuel supply has led to a large amount of gasoline not evaporating, or existing in the cylinder in the form of liquid, they can not be fully burned, and eventually discharged from the car with the exhaust gas, which also leads to the reason for the strong smell of gasoline.
Third point:
Under normal circumstances, after we heat up the car, the smell of gasoline will disappear, which also means that there is no abnormality in the engine and other places. But nowadays all vehicles carry a three-way catalytic converter, the main function of which is to fully burn the gasoline that has not been fully burned, so it can effectively prevent you from smelling gasoline.
But when we can still smell the gasoline after passing the hot car, then we need to check the condition of the engine to see if the engine is missing cylinders, after all, it is not harmful to check the vehicle for safety. But when the working state of the engine still has the smell of gasoline when it reaches the normal value, then we need to pay attention, we need to send our car to the repair shop to repair it, and check which place has the problem. We can see if the ternary catalyst shows signs of burning red after the hot car, and if there is, it proves that the gasoline in the exhaust gas has not been fully burned, then the ternary catalyst also needs to be repaired.
That's all about why we can smell gasoline in the car. The above is the reason for the appearance of all the gasoline smell of the car, if there is any reason for you, please leave a message in the comment area to discuss. The picture comes from the network, please contact to delete ah.
