The weather is cold. What happens when the car doesn't burn?

experts suggest: first check the spark plug
winter comes, as the temperature continues to decline, some of the car's small problems begin to appear. Recently, Mr. Zhang, who lived in double flow, entered the 114 hotline of the newspaper love car. In the last week, he found that the car was very difficult in the morning and sometimes had to be hit several times. At the same time, in the process of driving, often can hear abnormal sound.
for this purpose, reporter Lu Jingen, a senior automotive after-sales service expert, consulted this question. He suggested that owners should check the spark plugs first if they encounter difficulties in winter. The spark plug is the key of the automobile ignition system, and the ignition system is the key point of the engine work. Therefore, the performance of the spark plug is related to the performance and efficiency of the vehicle. How to pick the right spark plug, when to change? How to maintain the spark plug to make the engine more "strong"?
20 thousand km resistance spark plug has to change
the spark plug is a major component in the engine ignition system, all of which are spark plugs on the gasoline engine. One cylinder, one individual high-speed gasoline engine has two spark plugs per cylinder. The spark plug is used to introduce the high voltage generated by the ignition coil into the engine cylinder, and spark ignites the mixture between the gap of the spark plug electrode.
Lu Jingen told reporters that the spark plugs currently used are divided into resistance spark plugs, wave gold spark plugs and iridium spark plugs. Generally speaking, the life span of the resistance spark plug is 20 thousand kilometers, the lifetime of the sparking plug is 40 thousand kilometers, and the life of the iridium gold spark plug can reach 6 to 80 thousand kilometers. Therefore, the original spark plug of the low-end vehicle is a resistive spark plug, while the original spark plugs of luxury cars and high-end models are mostly iridium spark plugs.
how to determine how to determine the expiration of the service life of the spark plug? Lu Jingen indicates whether the spark plug needs to be replaced, and the dismantling will be known to see if the color of the burning, the gap between the electrodes, the gap between the porcelain body and the metal shell is leaking, and so on. In addition, he also said that if the car owners find that the car is more difficult to start in the state of a cool car, there is a clear sense of setback, idling jitter, or when the engine's acceleration performance drops, the spark plug should be checked in time. As a result of the above performance, it may be caused by the aging of spark plugs.
spark plug is not the more expensive the better
for the "winter car difficult" topic, the reporter immediately in a friend's club website launched an investigation, the owner of the car, Mr. Fang said, last month, his car after 20 thousand kilometers of replacement of the original spark plug, listen to friends said the iridium spark plug can Enough to improve the power performance of the car, and then, after 20 thousand kilometers, the acceleration performance of the economic car has declined, so it can not resist the temptation to spend "a lot of money" on the car to replace a set of iridium spark plug. After replacement and use, he felt that the acceleration performance of the car had not improved. He called himself a big head and was deceived.
for Mr. Fang's "Dang", Lu Jingen said that in fact, the improvement of vehicle power performance is not the more expensive the spark plug is, the better. Good spark plugs have some help for the power performance of the car, but the owner can't expect too much of this help, and the help of the spark plug on the power performance depends on the engine itself. If the engine does not reach a certain "level", the advanced spark plug will not have too much power performance. Help. But Mr. Fang did not have to be unfair to himself. "Although a good spark plug can not improve the dynamic performance of all engines, it will certainly reduce engine coke, prolong the service life of the engine, and have some help for fuel saving," Lu Jingen said.
clean spark plug is not difficult for the owner to do it yourself
when the car runs to a certain number of kilometers, the spark plug will produce the coke and the gap between the electrode. The coke will increase the fuel consumption of the engine, and the spark plug gap will cause the difficulty of the start. Therefore, regular inspection and maintenance of spark plugs can extend engine life.
Lu Jingen recommended car owners, maintenance should first clean up the air filter, to avoid dust with mixed gas into the combustion, so that the spark plug can be prevented from corrosion. Secondly, the owner can also remove the spark plug by himself and clean the dirt and coke on the ignition head. It is particularly important to note that when the spark plugs are disassembled, we should pay attention to the spark plug in and out, do not let the dust enter the cylinder, and clean up the surrounding in advance when the spark plug is dismantled. If there is oil in the cylinder, the piston ring or other components should be replaced in time, so as to avoid the short circuit of electrodes caused by spark plugs. In addition, the fuel oil is also closely related to the life of the spark plug. Therefore, the owners must pay attention to the refueling, and should not be greedy for the oil products that are cheap to add quality problems.
