Many friends will blindly think that the four -wheel drive of the SUV will be better than the two -wheel drive when choosing to buy SUV, but in fact, when we choose to buy a vehicle, we must know our needs.If you are, the two -wheel drive will be more suitable for your daily life. If you are an off -road, you will directly consider the four -wheel drive SUV. Let ’s take a look at the differences between the four -wheel drive and the two -wheel drive with Xiaobian!
Progressive power, strong passability, suitable for off -road
The four -wheel drive can distribute the power of the engine to 4 wheels, which can greatly improve the control and traffic capacity of the vehicle.At present, the four -wheel drive system is generally divided into: full -time four -wheel drive, time -sharing four -wheel drive and timely four -wheel drive.
The full -time four -wheel drive refers to the model of the 4 -wheel drive of the vehicle during the entire driving process.This driving mode has good off -road and control performance, but it cannot adjust torque distribution according to the conditions of the road. The disadvantages are relatively obvious, the fuel consumption is too large, and the economy is poor.
Time four -wheel drive is a driver mode manually switched by the driver. The driver can choose a two -wheel drive or four -wheel drive mode by connecting or disconnecting the brake.This is a relatively common driver mode in the SUV model. Its advantage is that it can ensure the dynamicity and passability of the vehicle, but also take into account the fuel economy. What is slightly insufficient is that the driver needs to judge the road conditions by himself and manually operate the driver mode.
Limited four -wheel drive is also known as real -time four -wheel drive. It is a driver technology that has only developed in recent years. It controls the two -wheel drive and four -wheel drive switching by computer chips.The significant feature of the system is that it makes up for their shortcomings while inheriting the advantages of full -time four -wheel drive and time -sharing four -wheel drive.It can identify the driving environment by itself and control the switch between the two -wheel drive and four -wheel drive according to the change of the driving environment.In the road with low adhesion such as bumps, Duo Duo Duo Duo, the vehicle is automatically set to a four -wheel drive mode to obtain a stronger traffic ability. In the flat road conditions such as urban roadsDrive to reduce fuel loss.If necessary, the driver of some vehicles can also press the "LOCK" key on the center console to achieve a full -time four -wheel drive.
The price is reasonable, taking into account off -road and city traffic
In recent years, my countrys SUV sales have continued to rise, but many of them are known as "high fuel consumption". The low -end SUV brand accounts for less than 40%of the market share, which shows that fuel consumption is still very good when buying a car when buying a car when buying a car. Important reference indicators.In order to meet the needs of consumers and fill the gap in the market, many domestic SUV models have launched two -wheel drive products, which are favored by many consumers.
In fact, the two -wheel drive SUV models are no different from the four -wheel drive model, whether it looks, interior, interior, or driving vision and driving experience.However, because it is a two -wheel drive model, the load of its engine is significantly reduced, and the fuel consumption has been significantly reduced.In addition, the price of SUV is generally lower than the four -wheel drive model.More importantly, most car owners travel between towns mostly. The four -wheel drive system is somewhat similar to them, and the owners must also bear more car costs for this.Therefore, for consumers who love SUVs shapes and controls but not the four -wheel drive function, the two -wheel drive SUV is more suitable.
Precautions for buying diesel off -road vehicles
Pay attention to
Diesel is a complex hydrocarbon mixture, so it is more difficult to ignite. It is a relatively safer choice for fuel.The quality of diesel is the guarantee of the "health" operation of the diesel engine. Inferior diesel containing water or impurities will cause serious damage to high -pressure distribution pumps.Therefore, for users, the best way is to carefully choose gas stations and ask for bills after refueling.
Diesel cars must not be able to add gasoline wrong. If the gas station staff mistakenly add gasoline, the owner should not mobilize the car, and immediately contact the maintenance station or 4S shop to seek technical support.
Pay attention to the second
The diesel engine is very durable, the speed of the diesel engine is relatively low, the wear of the engine components is relatively reduced, and the diesel vehicle does not have a high -pressure ignition system and the throttle valve body, so the engine failure rate is low.kilometer.However, the requirements of diesel engines are different from gasoline, and it requires special oil.And its maintenance time limit is related to the engine produced by each manufacturer and local oil products.For example, when the Land Rover diesel engine, when the sulfur content of fuel exceeds 0.7%, it is best not to exceed 6,000 kilometers. Of course, if the diesel is lower than this value, the maintenance cycle can reach 12,000 kilometers.
During use, the three filters of air filter, oil filter, and diesel filter should also be strengthened to give full play to their role.
Pay attention to
The power of diesel engines is very good and fuel -efficient. Diesel engines of the same displacement are much higher than the power of the gasoline engine, and the fuel consumption is also very low.However, diesel engines must not consume diesel after refueling, because in this case, the engine will be empty and inhaled in the air, which will cause the engine to be severely damaged.
Pay attention to the four
Most of the new diesel engines have a preheating plug device. The indicator indicates that the user is heating. When the engine is in a cold state, turn on the ignition switch. The light can be turned on when the indicator light is extinguished.If the engine is warm, the light is not bright, and the engine can be started directly.At the same time, the light also has alarm function. During the driving process, the indicator light shone, indicating that the engine management system failed.
Pay attention to five
Do not step on the refueling pedal when the diesel vehicle starts, do not start at the same time, and the speed should not be too high.When the engine runs at a high speed for a long time, do not shut down immediately. Continue to run for about 2 minutes at idle speed. After the temperature is reduced, shut down to avoid the accumulation of heat.
Pay attention to
Finally, get to know a concept-condensed point.The temperature that starts to liquidity at diesel is called condensation point.If the condensation point is too high, it is easy to cause the oil road to block at low temperature.The label of diesel in my country is made by condensation points. The height of the condensation point is the main basis for using diesel. Therefore, appropriate diesel should be selected in different regions and different seasons.
