Is a small displacement turbo really not suitable for a hardcore SUV? What do you think?

I think that the turbocharging of small displacement is not very suitable for the hard SUV, because the demand for power of the hard SUV is higher than that of ordinary models, if the power is insufficient, it will affect the driving, and the experience of driving will also feel very difficult. Land Cruiser This model uses the engine and the engine, if the displacement is too small, there will be a significant attenuation in power. Some hardcore SUVs will choose to use naturally aspirated engines, also because this kind of engine will be more reliable and more durable.

In fact, the turbocharged engine can also be used off-road, but the gap between the two engines is also more obvious after comparison. <>

Not all engines are suitable for off-road vehicles, and the engine also needs to have some characteristics, and the engine must have enough torque during driving so that driving on dirt roads will not have some problems. In the process of low-speed driving, the torque requirements for the engine are also relatively high, with many hard SUVs are used yes or displacement, only this kind of engine can withstand the hard SUV, but also to achieve real off-road. <>

The naturally aspirated engine is also in a weak position in terms of torque characteristics, and the turbocharged engine has more advantages than the naturally aspirated engine in terms of torque, but the fuel consumption problem of the turbocharged engine is higher than that of the natural information engine in the process of use. In fact, the turbocharged engine can achieve off-roading, and in terms of displacement and torque, it is more sufficient than the naturally aspirated engine. <>

Whether it is a naturally aspirated hard SUV or a turbocharged hard SUV, they all have their own advantages, and the reason why many models will choose naturally aspirated engines is also because of their better performance in terms of performance and lower fuel consumption.

You don't have to look at it, pull 5 people, you can know it uphill on the ice and snow road in the Northeast in winter, and you can feel it uphill in summer!! Try it yourself and find out!!

I think so, because whatever the boost is only enabled at high speeds, that is, the turbo does not intervene in the work when off-road.

I think that's true, because turbocharging doesn't help off-road, off-road looks at the displacement.

I think it's really not suitable. Because it will lead to a decrease in power and an increase in friction, resulting in a reduction in the life of the car.

I don't think there's anything wrong with it, because the performance of each car is different, so you can't generalize.

When it comes to turbocharged and naturally aspirated engines, it is impossible to say who is better, only that each has its own advantages.

At low engine speeds, turbocharging is often not started, so the power output of a turbocharged engine is no different from that of a naturally aspirated engine with a small displacement. At this time, the naturally aspirated engine with the same maximum power has a better power performance at low rpm due to its larger displacement and linear output. At high revs, when the turbo is turned on, the power output can be on par with a more naturally aspirated engine with a displacement.

However, there is a "turbo lag" of 1 2 seconds when the turbo starts, and many of its models will have a noticeable sense of abruptness, and the power will suddenly come out. The naturally aspirated engine, on the other hand, has a very linear power delivery and is relatively smooth from start to finish.

In urban traffic jams, where the engine is often at low revs, a turbocharged engine with a smaller displacement is more fuel-efficient than an engine with the same maximum power. Because in most congestion situations, the turbo is not started, which is only equivalent to a naturally aspirated engine with a small displacement working, and fuel consumption is naturally reduced. That's why major automakers have launched small-displacement turbocharged engines.

In simple terms, a turbocharged engine is the equivalent of a naturally aspirated engine with variable displacement.

Although the power output of natural aspiration is relatively linear, the overall power point is late, and the maximum torque can only be achieved at about 4000 rpm; The turbocharged model burst out of torque earlier, 1500 to 2000 rpm burst. Daily travel, 2000 shifts, supercharged models do have incomparable advantages, with fuel consumption equivalent to their actual displacement of natural aspirated models in exchange for times the power, but also in the economic speed range, double fuel saving. However, in terms of the smoothness and durability of the power output, as well as the maintenance cost, naturally aspirated has an inherent advantage.

There is a quote from one of Europe's top designers that sums up their dispute to the effect that turbocharging is an imperfect, compromising choice!

Off-road is naturally self-priming, and the power continuity is better.

Add T, like an off-road vehicle, mainly just to squeeze more power, but the power output is not linear enough, in the off-road to get out of trouble and so on, the power output is not linear, of course, if the large displacement plus T is also possible, such as Touareg and Q7, but these two supercharged versions or diesel TDI is better, because the torque range of diesel TDI is much larger than gasoline.

The domestic traffic situation is still self-priming, and the turbine does not play a role in many cases.

SUVs, of course, need to be supercharged, especially small-brand pseudo-SUVs for domestic use

Turbocharging helps to improve power and save fuel. However, maintenance costs after turbocharging are high.

In short, the pros outweigh the cons.

Is it better to be naturally aspirated or turbocharged for off-road vehicles Off-road vehicles are equipped with turbocharged engines such as the Haval H9, Haval H5 and BJ40. In recent years, turbocharged engines have become more and more widely used, and Japanese cars that started with self-priming are gradually equipped with turbocharged engines. The advantages of the turbocharged engine are self-evident, in the case of getting the same power output hail, the power is strong, the explosiveness is high, and the fuel consumption is low.

But the turbocharged engine has its inherent flaws from the day it was born, which is why it is not widely used in hardcore off-road vehicles. First of all, due to the presence of turbines, turbocharging can lead to power lag, whether it is a turbine blade with large inertia or small inertia, the power lag problem will manifest itself. However, the lag of power when off-road is very disadvantageous.

If an emergency requires electrical support, lagging power can be life-threatening. In addition, the structure of the turbocharged engine is complex. Although there is no problem with daily driving, it is easy to have problems when dealing with complex road conditions, and it is also troublesome to maintain in the field.

Moreover, there are many bumps in the off-road section, and it is inevitable that there will be such and such failures. The oil required to start the turbo is relatively high, and there are many gas stations in the city that provide No. 95 gasoline, but there is no high fuel supply in the remote no-man's land, which is embarrassing. An off-road vehicle without oil is really inferior to a person's legs.

Therefore, the general off-road vehicle is still more inclined to be equipped with a chain-lifting naturally aspirated engine, which can have a stable power output and good reliability. Turbocharged engines still have some drawbacks in off-road. @2019

Now the development of the automotive industry can be said to be very rapid, a variety of first-class models emerge one after another, and the engine is also increasingly updated. Recently, many friends have asked me whether to choose a turbocharged engine or a naturally aspirated engine for the same model.

How to choose between the two engines, let's first understand the advantages of turbocharged models, after the turbo intervention, the air intake of the engine will be greatly increased, the power will naturally be stronger, and it is more fuel-efficient than the naturally aspirated engine of the same displacement. The disadvantage is that turbocharged engine models not only have a higher price, but also have higher requirements for gasoline, engine oil, spark plugs, etc., and the maintenance costs in the later stage are naturally relatively high.

Therefore, turbocharged models are more suitable for consumers who have higher power requirements and have a very generous budget to buy and maintain a car. Let's take a look at the advantages of naturally aspirated engine models, which have a very long history of ownership, and the technology is relatively mature and durable.

SUV I recommend choosing a naturally aspirated engine, although Turbo can increase engine power, but the Turbo LAG phenomenon is inevitable, SUV needs power coherence and explosiveness when driving on non-paved roads, just like most of the decent off-road SUV models used above are large-bore V-arranged large-displacement engines, which want the explosiveness of power, or a large-displacement engine with a long stroke, and the consistency of power. However, due to the phenomenon of Turbo Lag, the Turbo engine is not actually suitable for off-road SUVs. I think the Turbo is more suitable for urban SUVs because the Turbo engine can produce more power at the same fuel consumption.

Each has its own benefits Individuals still prefer turbines.

Naturally aspirated is better than turbocharged! If you think about SUVs, it is recommended that the Global Hawk GX7 or Changan CS75 have quite a lot of naturally aspirated SUVs made in China.

1. High reliability, naturally aspirated engine After years of market testing, stable and reliable performance is definitely a highlight.

2. Low maintenance costs, compared with turbocharged engines, naturally aspirated engines have lower requirements for oil and oil products, and consumption is less, so the subsequent use and maintenance costs are also cheaper.

3. The power is smooth and linear, the intuitive feeling of the natural aspiration initiator is the linear power, theoretically how much power will come when the throttle is stepped on, as for the actual follow-up power to give people the feeling of surging power or getting weaker and weaker, it depends on the engine displacement.

I recommend the self-priming, the one with T is suitable for the highway, and the general urban road is still self-priming, which is easy to take care of.

SUVs or off-road vehicles are generally naturally aspirated, and the low-speed torque is larger when self-priming, and the power output is also linear, which is more suitable for off-road and bad roads. The starting power of turbocharging is weak, and the power is increased only when the rev speed reaches a certain level, which is more suitable for the road. Self-priming is recommended for SUVs.

The fuel consumption ratio is slightly higher, better than the speed, the driving is relatively smooth, often running on the high speed, often in the urban area to choose self-priming, the later maintenance is slightly more expensive.

Turbo power is better, and vehicle and vessel taxes are low.

In general, natural aspiration is recommended in cities, because traffic congestion does not exert the effect of turbocharging.

Advantages of naturally aspirated models:

1. High reliability. The naturally aspirated engine has been tested in the market for many years, and the stable and reliable performance is definitely a highlight.

2. The power is smooth and linear. The intuitive feeling of the natural aspiration initiator is that the power is linear, and theoretically the power will come as much as the throttle is pressed, as for the actual follow-up power to give people the feeling of surging power or getting weaker and weaker, it depends on the engine displacement.

3. Low maintenance cost. Compared with turbocharged engines, naturally aspirated engines have lower oil requirements and lower consumption, so subsequent use and maintenance costs are cheaper.

Advantages of turbocharged models:

1. Energy saving and environmental protection. With the same horsepower, the turbocharged model has a smaller displacement and has more advantages in terms of energy saving and emission reduction.

2. The cost of buying a car is relatively low. At present, most of the civilian models in China are equipped with turbocharged engines, and they can enjoy preferential purchase tax according to national policies when purchasing cars.

3. Abundant power. After the turbo intervention, the power will usher in an explosive period, and there will be a stronger power performance than the self-priming engine of the same level.

4. Fuel consumption has advantages. Theoretically, turbocharged engines will be more fuel efficient and consume more fuel than self-priming engines.

Disadvantages of turbocharged models:

1. High cost of use. Turbocharged engines are more precise than self-priming engines, and the requirements for oil will be higher, and it is generally recommended to add more than 95 gasoline. And self-priming engines can mostly eat coarse grains, 92 is enough.

2. High oil cost. Turbocharged engines also have higher requirements for engine oil, and it is generally recommended to use fully synthetic engine oil, and the consumption of engine oil is also larger, which is commonly referred to as burning engine oil. Self-priming basically has no problem in this regard, and you only need to change the ordinary semi-synthetic engine oil to change the oil.

3. High maintenance cost. Turbocharged engines have shorter service intervals than self-aspirated engines. Therefore, the maintenance cost is higher.

4. The abruptness of turbine intervention. Although some manufacturers have a lot of experience in the tuning of the turbo, there is still a gap between the turbocharged engine tuned by most manufacturers and the self-priming engine in terms of smoothness, especially the abruptness when the turbo is involved, and there is also a problem that the low torque is weak and the start is slow, which is also a common problem of many small-displacement turbocharged engines.

In summary, turbocharged engines and naturally aspirated engines can be said to have their own advantages and disadvantages, if the choice is completely up to personal preference, don't think too much.
