I would like to know what is the maximum torque and maximum power of a car engine

Power and torque are two of the highest indicators of a car.

1. The physical definition of power is the amount of work done by an object per unit of time. In the case of an internal combustion engine, we can understand it as the amount of energy produced by a fuel per unit of time. Therefore, power is only a physical quantity that describes the speed of workmanship, the higher the power, the more energy is produced per unit time, and often the top speed of the car is also higher.

2. The definition of torque on the engine refers to the torque output at the end of the crankshaft, and the magnitude of the torque determines the acceleration of the car. Therefore, torque is a physical quantity that measures the engine's ability to accelerate.

3. The relationship between power and torque: power = n torque speed, as can be seen from their conversion formula, n is a constant, then torque and speed are inversely proportional. This also explains why when the torque reaches its peak, it will drop sharply if it continues to pull up the rpm.

The output power of the engine has a great relationship with the speed, and the power of the engine increases accordingly with the increase of the speed, but after a certain speed, the power shows a downward trend. Generally, the maximum output power is expressed in terms of rpm per minute (r min) in the car instructions, such as 100ps 5000r min, that is, the maximum output power is 100 horsepower at 5000 rpm.

Maximum torque: the torque output by the engine from the end of the crankshaft, the torque is expressed as the maximum torque generally appears in the range of medium and low speeds of the engine, and the torque will decrease as the speed increases. Of course, the choice is accompanied by a trade-off of how to use it wisely without wasting existing features.

For example, it is necessary to turn on the air conditioner in Beijing in winter and summer, and it is necessary to take into account that the engine power should not be too small when choosing it; Just for commuting traffic on urban ring roads, there is no need to pick a high-horsepower engine. Try to achieve economical and reasonable engine selection.

1 horsepower = kilowatt.

1 kW = horsepower.

5500 means that the engine speed is at 5500

3000 means that the engine speed is at 3000

Maximum power (kw) means that the maximum output power in the engine at 5500 rpm is the maximum torque ( at 3000 rpm in the engine is the maximum torque output.

The maximum power speed is literally understood as the speed provided by the engine when it is running at maximum power, and the maximum torque is the torsional torque of the engine crankshaft.

The maximum power speed is literally understood as the speed provided by the engine when the maximum power is running, and the corresponding crankshaft speed when the engine outputs the maximum power is the maximum power speed. There is a direct relationship between the output of the engine and the speed, and the output of the engine will increase as the speed increases at the beginning of the output. However, when the output reaches its maximum, the output decreases as the engine revs increase.

The maximum power speed of different engines is also different. The maximum power speed of a general gasoline engine is 5000-8000r min, while that of a diesel engine is 3000-5000r.

The maximum torque is the torsional torque of the engine crankshaft, and the greater the torque of the car with the same transmission ratio, the stronger the torque. Maximum power is the work done per unit of time by torque and rotational speed. The maximum torque of a naturally aspirated engine is only reached at a certain speed, for example, 4,000 rpm reaches the maximum torque, 3,500 rpm may be 80% of the maximum torque, and 4,500 rpm may only be 50%.

We all know that turbocharged engines are strong, the maximum torque from 1800 to 5000 rpm is in the maximum torque range, in this speed range is the most powerful, below 1800 rpm or above 5000 rpm, it is weak.

In layman's terms, torque is force, regardless of speed, if you want to start fast, you can buy a very low speed that has produced large torque, but if you want to overtake fast on the highway, you must buy a high-power, that is, a large reserve power. The power of Dongfanghong tractor is only 60 horses, less than Wulingzai, but its force is huge, because there is no need to talk about speed, off-road vehicles only talk about torque strength, torque and engine and gearbox tuning is related. But the high power is only related to the engine, the power includes the strength and speed, if you want to overtake the cool or pick the car with the maximum power, the high torque may only be calibrated with the gearbox, it may start faster, but after the speed at medium speed, you will feel meat.

What does the maximum power and maximum torque of the engine mean? The maximum power and torque that the engine can emit is his most important index, whether it is a small horse-drawn cart or a large horse-drawn cart, which is evaluated by power.

Maximum power.

Maximum power refers to the maximum change in the energy of the circuit components in the unit time of the power supply, which is a physical quantity with magnitude and positive and negative. In this case, the maximum output power is specifically referred to. The higher the maximum power, the more devices the power supply can load.

Power: Power refers to the work done by an object in a unit of time. The higher the power, the higher the speed, the higher the maximum speed of the car, and the maximum power is often used to describe the power performance of the car.

Maximum power is generally expressed in horsepower (ps) or kilowatts (kW), with 1 horsepower equal to kilowatts.

Torque: Torque is the force that causes an object to turn. Engine torque is the torque that the engine outputs from the crankshaft end.

Under the condition of fixed power, it is inversely proportional to the engine speed, the faster the speed, the smaller the torque, and vice versa, it reflects the load capacity of the car within a certain range.

Maximum power: Maximum power is expressed in horsepower (ps) or kilowatts (kW). The output power of the engine is related to the speed, generally speaking, with the increase of the speed, the power of the engine also increases accordingly, but after a certain speed, the power shows a downward trend.

What does maximum power mean? It should indicate the maximum speed that the car can reach.

Maximum torque: the torque output of the engine from the end of the crankshaft, the torque is expressed as n m r min, the maximum torque generally appears in the range of the engine's middle speed, and the torque decreases with the increase of speed. We generally drive the engine in the city at 2000 3500 rpm, which means that the engine with a peak torque of less than 4000 rpm is the most suitable.

The maximum torque determines the car's acceleration performance, especially at low speeds. Compression ratio: The ratio of the maximum volume of gas in the cylinder before compression to the minimum volume after compression.

Engines with larger compression ratios burn faster and more fully, and the more power is emitted, the more economical it is. However, the larger the compression ratio, the more the vibration will increase when the engine is working, and the possibility of abnormal combustion phenomena such as "deflagration" and "surface ignition" will increase.

The maximum power determines how fast a car can run, and the maximum torque determines how good a car's acceleration performance is.

The maximum power of the engine is that he has such a big baby.

The relationship is as follows: 1. Torque is the product of force and force arm, that is, how many horsepower people often say.

2. The displacement is the amount of exhaust gas produced after the chemical combustion of gasoline, and the power is kw h to determine the engine efficiency.

3. Power determines the maximum speed, the larger the displacement, the stronger the power, and the greater the torque, the faster the acceleration.

Supplementary notes: 1. The mechanism that converts internal energy into kinetic energy is called the engine, and the form of automobile engine is mainly an internal combustion engine with cylinders and pistons as the conversion mechanism. According to the different fuel and ignition form, it can be divided into gasoline engine or diesel engine, or there is an engine fueled by hydrogen, natural gas and petroleum gas, and its combustion form is less different from that of gasoline engine.

2. According to the characteristics of the working cycle and the piston stroke, it can be divided into two-stroke and four-stroke engines, and the automobile engines involved in this project are mainly four-stroke gasoline engines or four-stroke diesel engines.

3. A gasoline engine is an engine that uses gasoline as fuel. Because gasoline is less viscous and evaporates quickly, gasoline can be injected into the cylinder with a gasoline injection system, and after compression reaches a certain temperature and pressure, it is ignited with a spark plug to make the gas expand to do work. The gasoline engine is characterized by high speed, simple structure, light weight, low cost and stable operation.

1. Torque mainly reflects the strength of a car, and its unit is N·m (N·m). Take an easy-to-understand example: there are two people, A can pick up a maximum of 50kg of dumbbells with all his strength, and B can only pick up a 25kg dumbbell with the same maximum effort, then it can be shown that A's strength is greater than B's.

By analogy, it can be said that the torque of car A is greater than that of car B, and usually, the torque will be said to be the same as the speed, for example, some cars will reach their maximum torque at 3000 rpm.

2. Another parameter that complements torque is power. The unit of power is kilowatts (kW), which is a measure of how much energy an engine is capable of producing. Again, an easy-to-understand example:

It's still the dumbbells that the two people lift the same weight, A has great strength, but the physical strength is not good, and they can only last for half an hour; b, although he has little strength, he is able to hold out for an hour.

By analogy, with the same load, A will do less work than B. Therefore, power is what determines a car's ability to accelerate continuously (i.e., its top speed).

3. Horsepower is another unit of power (abbreviation: ps) and the conversion relationship between them is: 1kw=. Some people often talk about how much horsepower, that is, power.

Overall, power can determine how much a car can go at top speed; Torque can determine how fast a car can accelerate, but when torque can't increase speed, then power needs to be relied on to increase speed. Therefore, power and torque go hand in hand.

With the rapid development of society, automobiles have entered our lives. For people, the car is a very important trading tool, and even an important partner for veteran drivers. But do friends really understand cars?

It is the power unit of the automobile, which is composed of two major mechanisms and five major systems: crank connecting rod mechanism, air valve mechanism, cooling system, oil supply system, lubrication system, ignition system and starting system. So what is the maximum power and torque of a car?

What is the maximum power and torque of a car? When it comes to the heart of the car, my friends know they're talking about the engine. As the engine of the car, the engine can be said to bear the power output of the entire car.

As for its function, some friends say that it is a connector for the fuel tank and transmission, and some people say that it is the output source of the car's power. A car's engine is like a computer's processor. The higher the frequency of the CPU, the better the processing power and the faster the speed, and the engine of the car is no exception.

In addition to the aura of the brand, it is the performance parameters of the engine, of which the engine is undoubtedly the core of the core. Complications aside, the average consumer only looks at the torque and power of the engine. What is the maximum power and maximum torque of a car?

Maximum powerMaximum power speed literally means the speed provided when the engine is running at maximum power, and the corresponding crankshaft speed when the engine outputs maximum power is the maximum power speed. The output of the engine is directly related to the speed. At the beginning of the output, the output power of the engine increases as the rev increases.

But when the output reaches its maximum, the output power decreases as the engine speed increases. The maximum power speed is also different for different engines. Most gasoline engines have a maximum power speed of 5000-8000 rpm, while diesel engines have a maximum power speed of 3000-5000 rpm.

What is the maximum power and maximum torque of the carThe maximum torque is the torsional torque of the engine crankshaft. Maximum power is the work done per unit of time by torque and rotational speed. The maximum torque of a naturally aspirated engine is only reached at a certain speed, for example, 4,000 rpm reaches the maximum torque, 3,500 rpm may be 80% of the maximum torque, and 4,500 rpm may only be 50%.

We all know that turbocharged engines are strong, and the maximum torque from 1800 to 5000 rpm is in the maximum torque range, and all of them are the most powerful in this speed range, and if they are below 1800 rpm or above 5000 rpm, they are weak. The above is all the content of the car repair I have for the maximum power and maximum torque of the car, for the maximum power and maximum torque of the car, I have introduced three aspects of the car for the friends, namely the car engine, the maximum power and the maximum torque, so after reading the car repair my content introduction, how much do the friends all know? In the afternoon, my content introduction can help you!
