What is the main thing for young people to see when buying a car? Of course, it is to be handsome, how can the appearance of a car not pull the wind attract the attention of the little sister? So the major manufacturers have mastered this psychology of consumers, began to work the appearance, for example, the number of exhaust pipes of different models is different, unilateral double out, unilateral single out, bilateral single out, bilateral double out, all kinds of shapes have, indeed to the car to add a lot of sense of sport. However, now many people say that in fact, from the number of exhaust pipes can be seen, the displacement of this car is large or small, the more exhaust holes mean that the larger the displacement, the more fuel consumption? Is this statement correct?
In fact, this statement is one-sided, and the displacement and fuel consumption of this car cannot be determined only by looking at the number of exhaust holes.
Generally speaking, as the exhaust device of the car, the role of the exhaust hole is to allow the engine to discharge the exhaust gas in time at work, and to achieve the role of purification and noise reduction. Originally some large-displacement cars are indeed to distinguish from ordinary cars, in the design of the exhaust pipe is different, add a few exhaust pipes, it looks like the visual impact is stronger, let people feel "so many exhaust holes, must be used to exhaust, indicating that the displacement is large."
In fact, the reason why such a statement is one-sided is because it is partial to the whole. Some large-displacement cars, it is true that multiple exhaust holes are needed to achieve the effect of eliminating exhaust gas, if there is only one exhaust pipe, then the caliber should be very large to ensure that the exhaust is normal, but the larger the exhaust port, the louder the noise caused, so in order to look good and reduce noise, many large-displacement cars will involve several exhaust pipes.
But if you say so, you can conclude that this car has a large displacement based on the number of exhaust holes, which is a bit exaggerated.
Now many private cars will also use unilateral double out, bilateral double out of the exhaust design, but these designs are actually not related to the displacement of this car, purely for the sake of good looks, let people feel that this car has a large exhaust volume, full of dynamics, generally this design is also used in sports models. Many knowledgeable old drivers said that the exhaust pipe on this type of model is designed by the real 4S shop in order to make money, and it can be said that "the more exhaust holes in this type of car, the more the price increase"!
In fact, for the exhaust design of the car, we do not need too much entanglement, because no matter how many exhaust pipes, they have undergone strict design and testing, as long as the engine maintenance is good, it will not affect our driving and control. The only thing we need to pay attention to is the problem of engine carbon deposits, which is the culprit that leads to increased fuel consumption and failed exhaust annual inspection. We can also manually clean the carbon deposit during daily maintenance, so that we are responsible for the car, what do you think?
