What's the difference between a three-cylinder engine and a four-cylinder engine? This is a professional answer

1. The engine is different. Balance is different: The key difference between a three-cylinder engine and a four-cylinder engine is that the balance is different. The balance of the three-cylinder engine is not as good as that of the four-cylinder engine.

2. The engine of a three-cylinder car has only three cylinders, and the engine of a four-cylinder car has four cylinders. Generally speaking, the four-cylinder engine is better than the three-cylinder engine.The more stable power performance is different. The three-cylinder engine has one less cylinder than the four-cylinder engine. The fuel consumption will definitely be reduced, and the maintenance will be relatively simple. Because the three-cylinder engine is smaller, the weight of the car will also be corresponding.

3. The biggest difference between a three-cylinder engine and a four-cylinder engine is that there is one less cylinder and many accessories. Moreover, the ride comfort of the three-cylinder engine is not as good as that of the four-cylinder engine. The noise of the three-cylinder engine must be louder than that of the four-cylinder engine, which is also the reason why many consumers don't like three-cylinder engines.

4. However, the smoothness of the three-cylinder engine is not as smooth as that of the four-cylinder engine, and the noise of the three-cylinder engine must be greater than that of the four-cylinder engine, which is also the reason why many consumers do not like the three-cylinder engine. Engineers are also using various technical means to make up for the shortcomings of the lack of smoothness of the three-cylinder engine.

5. [Pacific Automobile Network] The structure of the three-cylinder engine is simple, small in size, light in weight and easy in layout, while the structure of the four-cylinder engine is relatively complex. The three-cylinder engine has one less cylinder than the four-cylinder engine in terms of structural design. In addition, the three-cylinder engine loses less pumping air. Theoretically, the engine has one less cylinder, and the resistance will be smaller.

6. Lower weight brings higher fuel economy. And the volume of the three-cylinder engine is also smaller than that of the four-cylinder engine, so many hybrid cars will use three-cylinder engines. Hybrid cars use three-cylinder engines because the size of this engine is smaller, so an electric motor can be placed in the engine compartment.

The best engine thermal efficiency is only 41%, is it possible to reach 100% thermal efficiency?

Therefore, neither the current technology nor the application of materials can make the thermal efficiency reach 100%. It is impossible to increase the compression ratio infinitely. Theoretically, the higher the compression ratio, the higher the thermal efficiency, but the increase of the compression ratio is also limited.

The thermal efficiency reaches 100%. Are you kidding me? It's impossible. No matter how technology develops in the future, no matter how incredible it happens, it is impossible to achieve 100% thermal efficiency.

The thermal efficiency reaches 100%, are you kidding me? This is impossible. No matter how the technology develops in the future, no matter how incredible things happen, it is impossible to achieve 100% thermal efficiency.

For example, the thermal efficiency of Toyota engines is the first in the automobile industry toBrands that can achieve the highest thermal efficiency, once Toyota's best technology could only ensure that the thermal efficiency of the engine reached about 40%. Later, after years of efforts, the efficiency reached 41%, which can be regarded as the achievement of Toyota Hidapuben.

Of course, there are many reasons for heat dissipation. But these three points are the most serious parts of heat loss. Not to mention 100% thermal efficiency, 41% is not easy. If 50% of Mazda Chuangchi Blue Sky II is achieved, it will definitely be a landmark breakthrough. In fact, the engine is also a kind of thermal engine. As long as it is a hot machine, it is impossible to reach 100%.

The debate on whether a three-cylinder engine is good or not, perhaps the curtain can be pulled down!

1. So much so that some consumers who support three-cylinder engines think that three-cylinder engines are better than four-cylinder (naturally aspirated) engines! Because with the support of the turbine, the comprehensive performance of some three-cylinder engines is no worse than that of four-cylinder self-aspirated engines.

2. Therefore, there is no big problem. The basic advantage of a three-cylinder engine over a four-cylinder engine is that it is essentially more fuel-efficient (because it burns less fuel than a single-cylinder engine). The smaller the size of the engine, the less fuel it burns, so it is more fuel-efficient.

3. Of course, although the three-cylinder engine has more advantages, its disadvantages are also obvious, and its disadvantages are greater than its advantages. First of all, it is an indisputable fact that the noise of the three-cylinder engine is loud. Although it has improved compared with before, it is still insufficient compared with the four-cylinder engine.

Is the Meirui XL1.3T worth buying? Is the Maruibao XL three-cylinder engine reliable?

Is the Maruibao XL a three-cylinder? What about the Maruibao xl three-cylinder car? The 3t version of the Mairibao xl uses a three-cylinder engine with a maximum power of 121kw, a maximum torque of 240 Nm, and a maximum power speed of 5600 per minute. Turn.

The new Marui XL looks more handsome, and the power system is equipped with a 3T three-cylinder/0T turbocharged engine. The appearance is more handsome and dynamic, and the interior performance is more regular. When you first see the new Marui XL, you will definitely be attracted by the handsome and dynamic high-value appearance of this new car.

Therefore, the "3T+CVT" Marui is more like some low-end Japanese cars of poor quality. The 2020 Marui XL-550T version has a high comprehensive quality. 550T=LSY type 0T" engine, this machine is of course an in-line four-cylinder engine, and the NVH experience is much better than 535.

Let's talk about the power performance of the Marui XL. The car is equipped with a 0T/5L naturally aspirated engine, with a maximum power of 175 horsepower and 206 horsepower respectively, and a peak torque of 260 Nm and 253 Nm respectively.

The Merrybo XL3T is a car with a three-cylinder engine from General Chevrolet, but it can still be considered for purchase.
