The engine is the most important component in a car, consisting of thousands of components. When we buy a car, we generally consider whether the quality of the "three major parts" of the car is too good, and the inventory of the "three major parts" is the most important. In the daily maintenance of the car, the maintenance of the engine is also the most. The engine is like the "heart" of the human body, not only usually needs maintenance, but also always pay attention to details in daily driving to avoid the behavior of injuring the engine during driving. This time, not only beginner drivers, but even veteran drivers who have been driving for decades have to take stock of the five ways to hurt the engine the most. Please do not know until the next engine is scrapped.
Gasoline that is often added that does not match the recommended number varies according to the label of the petrol that needs to be added to the engine of each model. At the factory, the manufacturer recommends adding a label of gasoline and attaching it to the gas cover. Many friends may not pay attention to this detail. Different numbers of gasoline do not represent the quality of gasoline, but only the same thing. That's "explosion resistance." The higher the number of gasoline, the higher the explosion resistance. For example, No. 92 gasoline is not as good as No. 95 gasoline in terms of explosion resistance. On the other hand, some engines have high compression, and if higher number gasoline is used, gasoline can cause knocking when burned, improving stability. On the other hand, if the manufacturer proposes to add the engine of No. 95 gasoline, occasionally adding No. 92 gasoline once or twice will not have any impact, but if you often add gasoline that is inconsistent with the recommended number, it will inevitably affect the engine and cause engine wear.
Do not know the origin or often add gas station oil, the mainland has strict specifications for gasoline standards, personal gas station gasoline also meets the national standards, but in general Sinopec and Sinopec gasoline standards are higher, oil quality is better. Second, gasoline from household gas stations may store gasoline for a long time. After the oil has been settled for a long time, colloids will form. This colloid is easy to clog the injector and increase the fuel consumption of the car. In addition, gasoline that does not know the origin cannot be added again. The gasoline is cheap, but there is no guarantee of quality. If this inferior gasoline is used for a long time, the inside of the engine is prone to carbon deposition. These carbons are not cleaned up in time, gradually accumulating on top of the spark plug, slight pulling cylinder phenomenon, increased maintenance and maintenance costs in the later stage, and the problem of adding "inferior" oil, which is also common for some old drivers.
There is no habit of changing the oil regularly, and many drivers know that changing oil is the most common item. I know that I usually need to change the oil, but I have no idea when to change the oil. Some people say that every 5,000 kilograms, others say that every 10,000 kilograms, but in fact when the oil needs to be changed, it is clearly written in the maintenance manual that comes with the purchase of the car. As described in the manual, add oil on time, quantitatively, and by model. The role of the oil is mainly to lubricate the engine, for a long time do not replace the oil will make the oil emulsified or deteriorated, lose the lubrication effect, the situation is light, it will affect the increase of fuel consumption and the blockage of the oil circuit, heavy if the engine will directly become "cylinder scrap".
The engine is always high speed, the engine at the beginning of the design, taking into account the owner's fierce operation, designed to even if the speed is increased will not cause harm to the engine, but if always increase the speed, speed up, overload, will inevitably bring load to the engine, these so we in the daily driving, should avoid often increase the engine speed behavior, but also to avoid overload, overload. When driving a manual transmission car, we must also pay attention to the matching of gear shifting and power, learn which gear shift to use at what speed, and do not drive at low gear and high speed, which can reduce fuel consumption and maintenance costs, and it is also a safety behavior that we are responsible for traveling.
The debate about whether to heat a car in winter for a long time and whether or not to need a hot car in winter has long been debated, but in fact, the idea that the engine needs a hot car has so far misunderstood many people. The claim that the first car needs a hot car is actually some old models, and after the vehicle is started, it is necessary to wait for the antifreeze to heat up to about 90 degrees before entering the best condition of the car. But now many new cars With the advancement of science and technology and the improvement of materials, winter has not needed a long time of hot cars. Once the vehicle is started, it is possible to drive as soon as the oil pressure is established. Prolonged hot cars will only allow carbon to accumulate on the engine, with no other benefits.
Summary: The engine is the most important component of the car, we must always pay attention to keep the engine in the best condition, avoid overloading and other incorrect driving behavior, but engine technology after decades of development, is not as "fragile" as we think. If you develop the habit of driving, according to the maintenance manual to maintain the vehicle regularly, the current car engine usually travels more than 500,000 kilometers without major failures.
