How is the engine of a sports car different from that of other cars?

There is no difference between the two, and the reason why a sports car runs fast is not because of how powerful the engine is, but because of many aspects. The biggest difference between the two is the difference in configuration.

The V-shaped engine is to divide the cylinders equally into two groups, arranged in accordance with the V-shape, there is a certain angle between them, the angle is usually 90 and 60 degrees, there are also 45 degrees for racing, and some because of special requirements, there will be some non-special angles! There are also some supercars that use W12, W16, W18 engines!

Type B is a horizontally opposed engine, as you can tell from the name, the angle between the two sets of cylinders is 180 degrees, and the main engines currently used are Porsche and Subaru!

The L-type is an in-line engine, and many family cars currently use the L4 engine! The Audi 100 has an inline 5-cylinder engine, and the BMW has an L6 engine! First of all, there is no direct relationship between exhaust volume and engine displacement.

The most important thing to do with the exhaust volume is the geometry and volume of the exhaust system.

For example, a 125cc (displacement scooter can also make a loud noise after being modified to go straight out of the exhaust (common on the street), and it is even louder when the exhaust pipe is removed. In order to improve fuel economy, the general family car engine considers more the torque output of the engine at low speeds, because there is rarely a chance to drive the speed above 3000rpm in daily driving (otherwise it is too fuel-intensive).。This requires a high exhaust back pressure to ensure that the engine is charged efficiently at low rpm.

The sound attenuation effect of the exhaust system is contradictory to its exhaust resistance. The better the sound attenuation effect, the larger the volume of the exhaust system, the more complex the internal cavity structure, and the greater the exhaust resistance.

It can be seen that the maximum torque and maximum power speed are much lower.

One thing to clarify:This difference in external characteristics is not only due to differences in the exhaust system. Rather, when designing the exhaust system, it is necessary to consider the characteristics of the engine itself and match it.

I think the engine of a sports car is probably more powerful and stronger, so it can run faster.

I think the engine of a sports car is more bulky, ***, and faster.

The engine of this sports car is much more powerful than the engine of other cars, and the speed of the engine is also very high, and the function is relatively good.

The engine of a sports car is better than that of a regular car.

The engine of the sports car is more efficient, the starting speed is higher, and the power is sufficient, which is a better function setting.

The sports car engine performs better, has a greater power output and is able to accelerate in a short time.

Most sports cars use front longitudinal engines and rear-wheel drive.

It has to be much higher than the average engine speed to have a faster speed.

Its engine power is relatively large, and another is that it is also relatively noisy.

Yes, that is, the rev is faster, the fuel rate is higher, and the acceleration is faster.

Off-road vehicles require lower oil quality than sports cars.

The sports car has a lot of horsepower, so it can run very fast.

The torque of the off-road vehicle bursting out at low speed is large, so it is powerful.

The quality of the oil is determined by the compression ratio of the cylinder, not by the relationship between the old and the new engine.

The large displacement is for sure, but the place of play is different.

Absolutely original.

The engine of a sports car focuses on high revs and horsepower. The engine of an off-road vehicle, on the other hand, focuses on stability and torque.

The sports car engine is generally a four-cylinder engine, and the bore is larger than the stroke, which is conducive to a rapid rise in speed, and after the compression ratio increases, the torque will also be increased accordingly, so it is a high-speed and high-torque engine.

Off-road vehicles do not require much horsepower, and are generally single-cylinder or double-cylinder, and four-cylinder vehicles are rare. Off-road vehicles generally pay more attention to the play of torque, because to climb these hills, horsepower determines speed, and the speed of off-road vehicles does not require how fast, but the torque must be sufficient. So that is, the engine of the off-road vehicle is a stroke that is larger than the bore.

I put the stroke and bore to put it bluntly, that is, the cylinder is a cylinder, the cylinder of the sports car is a little shorter and thicker, and the cylinder of the off-road vehicle is a little longer and thinner, and that's it.

If you put a sports car engine on an off-road vehicle, you can also do it, but how to change it depends on what model you are. As for whether the performance can be fully played, there are too many things to do, and it is not something that can be said in one or two sentences.

Clause.

First, the real off-road vehicle is completely different from the SUV in the city, and the off-road vehicle of a professional rally like Chevrolet burns diesel, because the internal combustion power of gasoline is not as high as that of diesel.

Clause. Second, the displacement of off-road vehicles is definitely much larger than that of supercars, except for some top-of-the-line sports cars. Even if the Lotus trot and the Porsche 911 are 90 gasoline in the United States. A high gasoline number does not mean that there is a lot of power. For details, please see the introduction of the gasoline number.

Clause. 3. The engine system and suspension system of sports cars and off-road vehicles are completely different. The engine of a sports car pays more attention to the problem of horsepower, and the engine of an off-road vehicle pays more attention to the problem of torque; In addition, the suspension of the sports car is to maintain the balance of the body at high speeds, and the suspension system of the off-road vehicle is to keep it more stable in the obstacle course.

I guess your question should be explained.

No, the engine of the off-road vehicle can be added to the old gasoline, and the 97 of the sports car is reluctant, if it goes to remote areas such as Qinghai-Tibet, it will die if there is no gas.

The engine types of sports cars are:

V6 engine, V8 engine, V10 engine, V12 engine, W16 engine, H4, H6 engine.

These are the engines that are commonly used in sports cars, and there are also some L4 engines, which are in-line fours.

First, the V-type engine is a V-shaped two-row piston side view, and the W-type is a combination of two V-shaped engines, and the two V-shaped combinations are WH-type engine, which means horizontally opposed engine.

The V-engine's small height and length make it easier to arrange on a car. In particular, modern automobiles pay more attention to aerodynamics, requiring the car to have as small a windward side as possible, which requires the engine cover to be as low as possible. In addition, if the engine length is shortened, more space is left in the cockpit.

Since the cylinders are staggered from each other, it is convenient to increase the displacement and power by enlarging the cylinder diameter and is suitable for higher cylinder counts. In addition, the V-shaped engine cylinders are arranged in opposite directions, which can also counteract some vibrations, making the engine run more smoothly.

The disadvantage of the V-engine is that it has to use two cylinder heads, which is more complex and costly. In addition, after its width is increased, the space on both sides of the engine is smaller, and it is not easy to arrange other devices.

Second, the W-type engine, the W-type engine is the exclusive engine technology of German Volkswagen. The V-shaped engine is staggered at a small angle on each side of the cylinder to form a W-shaped engine. In other words, the cylinder arrangement of the W-type engine is composed of two small V-shapes to form a large V-shape.

Strictly speaking, the W-type engine should also be a variant of the V-type engine.

The W model can be made shorter than the V engine, and the crankshaft can be shorter, which saves space on the engine and is lighter, but it is wider and the engine compartment is fuller.

The biggest problem with the W engine is that the engine is divided into two parts as a whole, which is bound to cause a lot of vibration when operating. In response to this problem, Volkswagen designed two counter-rotating balance shafts on the W engine, so that the vibrations of the two parts cancel each other out internally.

3. H-type engine.

Low center of gravity: The lateral vibration generated is easily absorbed by the bracket, effectively lowering the center of gravity of the heavier engine of the whole car, and making it easier to achieve overall balance.

Low vibration: The piston movement is well balanced (around 180 degrees offset). Compared to the in-line type, the counterweight factor required for the crankshaft is reduced, which helps to increase the rotational speed.

It can maintain a low speed of 650 rpm and ensure that the engine works smoothly. It also has the lowest fuel consumption compared to other engines.

I chose the H-type because the H-type engine is a Porsche haha.

The automobile engine is the initiating part of the engine, including fuel injectors, spark plugs (diesel cars do not have spark plugs), pistons, cylinders, intake and exhaust systems. If there is carbon deposit in this area, the car will not run smoothly.

In fact, many people have heard the word engine tuning (jiao), through different tuning, even if the power and even torque curve are the same, you can also get different power performance. Especially in the current situation that many parts of the engine are controlled by computers, two or even several completely different performances can be achieved through different control programs. There are many factors that affect the performance of the engine under different working conditions, such as fuel injection program, ignition timing control, camshaft timing control, etc., which can have an impact on the power under a certain working condition, and even the throttle valve will be different due to the different tuning.

For example, in comfort mode, even if you press the accelerator pedal deeply and give the computer a signal to open the throttle, the computer will delay the opening of the throttle in order to make the acceleration smoother and the fuel more economical, and you will feel that the power is not coming as expected. On the contrary, in Sport mode, even if the throttle is shallow pressed, the computer will deliberately make the throttle open faster and bigger, and the power will be very strong at this time.

The car engine can be said to be the heart of the car, there may be many car lovers who think that the engine used in different models of different vehicles will be different, in fact, although the ** of some vehicles is very different, but the engine is the same. Today, let's take a look at the same engine used in those cars.

1. Mitsubishi 4A91 engine.

Let's talk about Mitsubishi engine first, Mitsubishi is China's largest engine manufacturer, Chi Wei and this Mitsubishi 4A91 engine is also very common among riders. For example, Southeast V5 Lingzhi, V6 Lingshi, Dongfeng Fengxing Jingyi, Zotye Z300, Zhonghua FRV, Mazda2, etc. all use this engine.

2、prvv6

Peugeot, Renault and Volvo jointly developed the PRV V6 engine, this engine is not only installed in Peugeot, Volvo, Renault, but also in more than a dozen car brands such as Citroen, Dodge, Lancia, etc.

3. Ford DurateCV6

The DurateCV6 has been used in almost every Ford Group, including Ford, Lincoln, Mercury, Mazda, Jaguar and Aston Martin, and is now derived from the EcoBoost V6 engine promoted by Ford.

It's not the same. Although the engine equipment is the same, the gearbox is different, so the power performance is also different.

The dynamics are of course the same. Now it is very defeating to talk about different car models, including the same engine. And the power of the engine is only related to the displacement of the engine.

I think the power performance is still different, and the power of each engine is different.
