排量和油耗（Displacement and fuel consumption）

排量和油耗（Displacement and fuel consumption） 排量和油耗(Displacement and fuel consumption) Emissions and fuel consumption between the larger displacement car fuel consumption more, but not quite, the 2 city driving engine throttle less, so the displacement of 2 fuel consumption will be a little, on the highway, because it is constant, so the displacement of 1.6 less fuel consumption. Many people think that if a car is increased by 20%, then its fuel consumption is well deserved to increase 15%-20%. But in fact, does not have a direct proportion relationship between emissions and fuel consumption. Automobile fuel generated energy is divided into three parts: the first part is used to overcome the resistance of the car, including the sliding force of tire rolling resistance, air resistance and the acceleration of the inertial force and climbing; the second part is the use of the engine itself and dissipation; the third part is the transmission system losses. In the driving situation under certain circumstances, the car driving resistance and its displacement almost Never mind. Especially in the straight road speed, air resistance and rolling resistance of tire of the vehicle only design and car and body shape, tire speed, has nothing to do with the displacement. In accelerating or climbing, big cars are just because of some more weight and produced a little extra resistance, but the extra resistance is usually not worth mentioning. Of course, if someone wants to give full play to the power of big cars, playing need for speed in the street, then he will become a regular gas station. When the engine speed under the same large displacement engine needs more energy utilization and dissipation. Because of the large displacement engine with sliding valve spring stiffness, inertia greater connecting rod and piston and greater resistance to the side, these parts of the "The new supersedes the old. consumes more energy.". At the same time, arch-criminal more ventilation loss and heat loss is large displacement engine fuel consumption high. But for the reason of the driver, the larger displacement means lower speed, it will offset some of the excess fuel consumption. The transmission system losses are the three parts in the least, and the size of displacement is independent. For the automatic transmission, the energy loss is only related to the size of the engine output, which normally output large displacement engine is not much bigger than the small displacement engine. For the manual transmission car, we can ignore the transmission loss. Modern vehicle engines are using the electronic fuel injection technology, computer not only because of a greater engine displacement and more fuel injection. Compared with the small displacement engine, large displacement engine usually just to maintain and drink The new supersedes the old. needs a little oil. Only when you really need it came, it will truly reflect the strength and appetite The meaning of gold displacement "Gold displacement" meaning can be interpreted from 3 aspects: 1, have the characteristics of fuel economy; 2, good control, power and comfort; 3, can satisfy consumers in various forms, such as business, travel, tourism and so on. In other words, can satisfy the needs of consumers in the car, and has reasonable price models, namely, gold gold displacement models. At present, there are two different views. Some people think that the market capacity of the largest 1.6L cars, should be elected, but most people think that 2.0L is the displacement of today's auto market gold displacement. 2.0L seems to be more fully elected reasons: one is because the vast majority of manufacturers spend more energy in the design of 2.0L cars, look more dignified and delicate, and the displacement of the various models of price and make the most of the consumers, in line with Chinese a good face psychology; two is more commonly used 2.0L models advanced technology cars, compared with the displacement of 1.6L has obvious advantages, the fuel economy and the use cost is better than 2.4L and larger displacement models. While for car prices, 2. The 0L model described as fame and fortune, because it can not only enhance the brand awareness, and considerable profits, so even if the current car city 2.0L the Legion has very bloated, there are still many manufacturers have introduced new models of the displacement.

The characteristics of the short wheelbase of the opposite seat, vertical space cramped, speed instability, steering flexibility improved, small turning radius, strong maneuverability. This situation is obviously: the shorter wheelbase is good for off-road vehicles. Also because the design orientation, off-road vehicles do not consider speed. As for the Wrangler two door and four door. It depends on your LZ off-road vehicle use, if you only then choose the two door SUV version. I think four compared with daily use. There are many things in this way, there is no good or bad, is good.
