In a dozen years ago to buy a car or a big deal, actually there are people and therefore a large banquet, but now, buying a car has become another way to shop outside the shopping, casually buy a car is not minority, after all, and real estate is different is that the automotive industry is often “price change”, BBA under high discounts have become commonplace, not to mention the original price is not high brands. However, when buying a car has become the norm, the car has become the livelihood of attention, look at the prices in 2019 will always be more than the price of fuel, as well as the older generation of “large displacement equal big fuel consumption,” conclusion, as well as the original are equipped with a naturally aspirated 3.0 or later God car engine, is also changed to high power 2.0T turbocharged engine version, is not the phenomena are explained, this view is correct, that is to say, a large row = amount of high fuel consumption, fuel-efficient small-displacement =, but really true? The car circle pseudo-proposition, in the end how much white it will deceive it?
in the end what is the displacement of
estimates before saying this, a lot of people will say that the size of the displacement of rhetoric, but really want to say to what is displacement, as well as the specific definition of displacement, many people do not know, then what trespass ghost girl here, in fact, the cylinder volume of the engine, that is to say the greater the volume displacement of the engine cylinder together, the greater the displacement , if the change in the human body, it is vital capacity, so a question arises, you can not eat and lung Does it matter? It was the stomach, big brother, and stomach is a relationship, so basically emissions and fuel consumption are not directly related.
What can determine fuel consumption
Since the emissions and fuel consumption does not matter, then in the end what is the level of consumption of deadly factors that determine it? In fact, there are many, in the first place is the weight of the vehicle, which is good to understand it, of course we need more heavy fuel, light course will be relatively less. The second point is the resistance, whether it is air resistance or drag the drive, there is also a ramp or friction resistance, are resistance, which will impact on fuel consumption, which is one of the most obvious is air resistance, wind resistance is on, a lot of fuel and fuel-efficient vehicles are not, it depends largely on the drag coefficient.
Next,It should be the engine fuel kinetic energy conversion rate, with no displacement this relationship, as long as the engine, it will have to squeeze out power, and power is squeezed more and more, of course, the higher the efficiency. At this point, naturally aspirated will occupy more kinetic energy, and with under-horsepower high-power, high-power than the turbo will be more economical fuel consumption.
Why do low-emission fuel-efficient
See here and someone will say, that really is my turbocharged naturally aspirated fuel-efficient than friends ah, this is supposed to say? The reason is simple, because adding newer and more advanced technologies, such as the tenth generation Honda Accord, in comparison with the previous generation, the biggest change is the use L15B 1.5T turbocharged engine replaces the ninth generation of the 2.4L naturally aspirated 2.0L K24Z2 and the R20A. Because the use of new technology, so of course, be in power and fuel economy improvement, in addition to other vehicles beyond this vehicle, have the same example, now in the fierce market competition, it also resorted to their own housekeeping skills.
Guiche: Why are so many cars now are taking small displacement of the wind, not simply because of money, because more rows the amount of tax reasons, large displacement in fact, there are many inherent advantages, small displacement but also to more environmentally friendly.
