1 4T powertrain or 1 5L powertrain, which system is more fuel efficient?

In general, the fuel consumption of the self-priming engine is significantly higher than that of the engine, but after the engine turbine enters the work, the fuel consumption of the self-priming engine is lower than the engine fuel consumption. A few words about my personal reasons.

First of all, it should be noted that fuel consumption is not only determined by engine displacement, in fact, it is related to many factors, such as road conditions, driving habits, etc., if you remove the other 10,000 fuel consumption factors, and compare fuel consumption with engine displacement and turbocharging, then the above conclusion is absolutely correct, and there is no controversy.

Secondly, the fuel consumption of the self-priming engine is actually very easy to calculate, the larger the displacement, the greater the fuel consumption, such as the self-priming engine must be larger than the self-priming engine; The opposite is true, the fuel consumption of the self-priming engine must be less than the fuel consumption of the self-priming engine, so the exhaust volume of the self-priming engine is equal to the fuel consumption, which is quite easy to calculate. However, turbocharged engines are slightly different from self-priming engines.

The principle of turbocharged engine is also very simple, that is, the exhaust gas inertia impact force sent by the engine is used to promote the turbine to rotate, and after the turbine rotates, it drives the coaxial impeller to rotate, so as to supercharge the intake of the engine and make more new air enter the engine. Because the air density in the cylinder of the turbine engine is much greater than that of the self-priming engine, in order to fully burn the air, more fuel must be injected, so that the conditions of the engine displacement can be completely changed and the output power of the engine can be increased.

At present, the turboization of small-displacement vehicles has been the trend of the times, and all major automobile manufacturers are taking this road, mainly because of the applicability of small-displacement vehicles in dealing with various working conditions is not strong, but with turbocharged engines, it can make small-displacement vehicles more widely used in working conditions, which has become the consensus of the industry and the future development direction.

If you run in the city, it will definitely be more fuel-efficient in liters, but if you run at high speed for a long time, the engine will be more fuel-efficient.

It is definitely that the latter is more fuel-efficient, because the power of the latter is worse than that of the former.

The horsepower is stronger, that is, the power is higher.

However, the torque ratio is larger, that is to say, the acceleration in a short time, or the explosive force ratio in a short period of time is stronger, which is more suitable for overtaking. The ratio of the high-speed is more comfortable, first of all, the speed of the high-speed itself is at 2000 rpm, at this time, the turbo work efficiency is excellent, the supercharging value is also very large, and the high-speed overtaking is still faster.

under similar parameters. If you want to self-prime, you don't lose the turbo, then the red line shifts.

Otherwise, the self-priming air has parameters, and the full performance cannot be exerted.

We are typing the answer by hand, so please be patient for a while. I'll give you a solution in a few minutes, thanks! ❤️

The maximum power of the engine is 150 hp, and the maximum power of the engine is 154 hp, and in this data it can be seen that the naturally aspirated engine is slightly superior. However, in terms of torque, the peak torque of the engine can reach 250 Nm, but the peak torque is only 204 Nm, and it can be seen in these figures that the turbocharged engine is more powerful than the naturally aspirated engine. So it's more suitable for overtaking.

Which is better turbo or self-priming? What is the difference in power levels? The old driver came to tell you.

If we judge empirically, the power of turbocharged engines and naturally aspirated engines is comparable, but if we look at this comparison from a rigorous point of view, there is no universal answer, and we must compare specific engines before we can draw a pertinent conclusion.

The engine is a very complex multi-component machine, and it is difficult to judge its merits and performance by one or two constraints. Therefore, it is more meaningful not to pay too much attention to the performance parameters and technology of the engine itself, but to focus on the actual driving experience and performance feeling.

The engine is only the initial part of the vehicle's powertrain, and it also needs to go through a long drive system to transmit power, and often the performance of the transmission mechanism has a greater impact on the driving quality of the vehicle.

Difference with high horsepower:

1. The engine is different

It is a natural inhalation to start the blind circular machine. The turbocharger is a professional technology, which is more fuel-efficient, environmentally friendly and more powerful than the naturally aspirated engine. It is a turbocharger and a direct-injection engine.

The turbocharger is a professional technical grinding side collapse technique, which is more fuel-efficient, environmentally friendly and driving force than the natural start-up aspirated engine.

2. The fuel consumption and maintenance cost are different

Taking the A-class car as an example, the Lei Ling and the Nexera are both in fuel consumption of a little more than 7L, which cannot become an influencing factor in the purchase of a car. In terms of maintenance costs, there is not much difference between the three-cylinder engine and the usual four-cylinder engine.

In terms of fuel efficiency alone, it is better.

But it's better to bring T or L, it can only be said that each has its own strengths, and what suits you is the best.

The engine with T is to add a turbo to the engine with L, so that the air intake increases, which can make the combustion of fuel more intense, such an engine can provide more powerful power to the car, and at the same time can also play a role in fuel economy. The engine with L will be worse in power than the engine with T, so the price of the car with T will be relatively higher.

But judging the quality should not only look at the motivation, we also have to look at the second point.

The second point is the smoothness of the power output. At this point, the engine with L is obviously better than the engine with T, because the engine with L will not burn violently when the fuel is working, and it is relatively stable when it burns, so the power that the car can get is also relatively dry and stable, and the comfort of the car will be higher.

In addition to these two points, when buying a car, you should also consider the maintenance costs in the later stage.

This is the last point to be said below, because the engine with L is naturally aspirated, and the overall structure is much simpler than that with T, so it is very convenient when repairing, and the cost is relatively small. The structure of the engine with T is more complex and precise, so it is difficult to maintain and the cost is relatively high. Therefore, when buying a car, whether you want to buy one with L or with T, you still have to think clearly.

It's not a good choice between the one with t and the one with L, but you should choose the one that is most suitable for you.

If you often run at high speed, it will be more suitable to buy a T one, because the car has strong power, no stop-and-go fuel consumption, and relatively low. If you often drive in the city, it is best to choose with L, the car power is completely sufficient, and the comfort of stop-and-go parking is better. There is no need to buy a car with T to drive in the city in order to save fuel, not to mention the comfort of the car, the fuel consumption may be higher than that with L.

Because the turbine will only start when the engine speed reaches a certain speed.

For example, the sum on the same Volkswagen car.

Theoretically high fuel consumption ratio.

But it's a more efficient dual-clutch transmission.

The matching is a 6AT with a slightly worse efficiency

In fact, the advantages and disadvantages of the two combinations in terms of fuel consumption are leveled out by the gearbox.

The power team is still slightly better.

And how much is the difference in power.

Hello dear! The difference with the power is relatively large, it is turbocharged is equal to the power of natural aspiration, and the ratio is different. First, T is the abbreviation of Turbo, which means turbo override.

L is liter, liter meaning, refers to the displacement of the engine for how many liters, there is no ear stool T behind the displacement and the L is generally a naturally aspirated engine. Second, the power of the car is turbocharged, and the power ratio is strong, but it is expensive and maintenance. Third, the power of the car is weak, and the acceleration performance of the general car is poor, but it is cheap and the maintenance is cheap.

Fourth, the displacement of the power of the car is better than guessing the brigade. But the consumption of oil is also greater.

The engine is more fuel-efficient. Generally speaking, the engine is more fuel-efficient, but the turbine engine is a little more complex than the self-priming engine because of the machine itself, because there is an additional turbine component, the price will be relatively higher, and the subsequent maintenance of the turbine will also cost some money. The cost of later maintenance is higher.

Naturally aspirated engines last longer, and turbocharged engines deliver more power and torque. The output of the naturally aspirated engine is more linear and stable, like the Rolls-Royce, which basically uses a large-displacement naturally aspirated engine, and only the participating models use turbocharging.

Turbocharged engines can have hysteresisTurbocharged engines will have hysteresis, especially those with a lower grade of the car, the frustration will be more obvious, but this phenomenon can be adjusted by technology, after adjusting the vortex of most cars is still very timely, and the frustration will not be particularly obvious. However, because of the addition of turbine parts, the price will be relatively higher, and the subsequent maintenance of the turbine will also cost some money.
