Racing Engine Data ??? The difference between the engine of a racing car and a sports car

Every team's engine is different.

1. Different places of use.

A supercar is an ordinary car that can be driven on the road, and it does not require much smoothness on the road; Racing cars are not allowed to drive on the road, only on the designated track, the smoothness and friction of the road surface, imitation and even wind and rain have a great impact on the racing car.

2. The composition of the car is different.

Supercars are all the components of the brand's entire range; Car notices are usually modified sections. Different tires can be changed for different road conditions and weather conditions during the race. The steering wheel of an F1 car is usually split and configured by the driver himself, and changing one part of the car, such as the engine, will have a big impact on the outcome of the race.

3. Different configuration functions.

Supercars are used for home use or collections. There are a lot of entertainment features in the configuration, and you can modify the speaker channels, interior, and more to your liking. The purpose of racing is to race, and the demand for entertainment functions is not particularly large, mainly because the requirements for safety and convenience are relatively high in configuration, so comfort will be affected accordingly.

From the birth of the car to the present, the speed has never stopped! Aerodynamics, a faster, more efficient drivetrain, grippy tires, and an air suspension that can adapt to changing road conditions are all powerful tools for speed. Of course, there's a more straightforward and effective way to increase speed – a more powerful engine!

First of all, what is an engine, an engine is a machine that converts chemical energy into mechanical energy. There are several types of engines, the most widely used of which is the reciprocating engine, also known as piston engine. It usually consists of a crank linkage, a valve mechanism, and five systems:

Lubrication, lubrication, cooling, ignition and starting. The crank linkage mechanism consists of a cylinder block, cylinder head, piston, connecting rod, crankshaft and flywheel. This is the mechanism by which the engine generates power and converts the linear reciprocating motion of the piston into the rotational motion of the crankshaft to output power.

The parts and components of racing engines should work at higher speeds, temperatures and compression ratios, and their requirements for materials and technology are naturally much higher than those of civilian engines, especially those directly related to speed, temperature and pressure, such as cylinders, pistons, connecting rods, timing, injection molding and cooling, which require high strength, high temperature resistance and wear resistance.

For example, if the strength of the piston connecting rod is not enough, it will inevitably affect the running trajectory of the piston, the power supply connection is not smooth, and in the worst case, the cylinder will burst directly; Or the piston ring wear resistance is not enough, which will inevitably lead to the air tightness of the cylinder. The power slide is a big deal for every minute of the game.

Racing engines, in order to meet the strength requirements, need to replace racing engines with new materials such as high-strength forged aluminum, titanium alloys, magnesium alloys and carbon fiber. No matter how much it costs, as long as it is expensive and easy to use. For naturally aspirated engines, increasing the rpm is an effective way to increase the power, but increasing the rpm is not easy.

As the speed increases, the piston will rub against the cylinder faster and the crankshaft will move faster. In order to maintain the durability of these components, almost all engine components need to be particularly strengthened.

It is said that the competition field is the touchstone of engine technology. Improving the performance of the engine from a new perspective has great benefits for the advancement of engine technology. Looking at current civilian engines, many technologies have been introduced from racing cars, such as turbocharging and diesel-electric hybrids.

The configuration of the racing engine is that the car has a large displacement, a very large cylinder block, 4 valves per cylinder, equipped with a naturally aspirated engine, and the maximum power of the car is 700 horsepower.

Thermal motor, turbocharging, dual-clutch transmission, paddle shifting, naturally aspirated, these configurations are very good, and the horsepower is very good.

The duplex engine has a crank connecting rod and has 5 systems for better power output, with cylinders, connecting rods and pistons.

Let's talk about the speed first, the ordinary engine is generally 12,000 rpm, and the racing engine can easily go up to 20,000 or even 30,000 rpm.

Speaking of displacement, I don't know what the concept of what you call an ordinary engine, in the case of the most common 125 in China, then it refers to a single cylinder with a displacement of 125cc. The general racing engine is an in-line 4-cylinder or V-shaped 4-cylinder, and the displacement is generally more than 1000cc. The advantage of a multi-cylinder engine is that it runs more smoothly and has less vibration, as is typical of the straight 4 engine.

One, four, two, three two up and down work at the same time, can offset the inertia of the piston up and down operation. And there is another difference between the racing engine and the street car engine of the same displacement, the angle of the front is larger, so that the engine accelerates faster.

On a second note, in order to dissipate heat faster and more evenly in high-revving engines, racing engines typically have a built-in water circulation system with internal water channels flowing through the cylinder block and separate fins and fans.

Horsepower: A unit of power, 1 horsepower is equal to the work done to lift a 75-kilogram object by 1 meter per second. It should be related to the ability to accelerate.

Speed: The speed of the engine is related to the number of work times per unit time or the effective power of the engine, that is, the effective power of the engine changes with the different speeds. Therefore, when explaining the effective power of the engine, the jujube branch must also indicate its corresponding speed.

The effective power specified on the engine product label and its corresponding speed are called the rated power and the rated speed, respectively. The working condition of the engine at the rated power and rated speed is called the calibration condition. The rated power is not the maximum power that the engine can emit, it is the maximum use limit of the effective power of the stool posture according to the use of the engine.

The nominal power value of the same type of engine is not the same when its use is different. The effective torque also varies with the engine condition. Therefore, the maximum torque that the automobile engine can output and its corresponding speed are used as an index to evaluate the engine dynamics.

The more horsepower, the faster you can propulsion, and if it's f1, it's completely different from 850 and 900. But the smaller the horsepower, the more fuel-efficient. Commonly used cars, it is recommended to adjust the horsepower to a little noisy.

The speed is nothing, just a trillion to guess how much your engine revs in 1 minute. 4000 is 4000 rpm. It's not the ability to accelerate, it's just how fast you use the revs to **.

The engine of the car moves through the pistons, which produces the rotational speed, which is the speed of rotation, which is how many revolutions it makes in one minute.

Horsepower is the unit of power, and power is the force multiplied by the speed and the torque multiplied by the speed, so the power is determined by both torque and speed.

The maximum speed is determined by the road conditions, tire conditions, vehicle quality and other aspects, and the overall speed is when the power is equal to the resistance, that is, the ......Maximum speed is related to horsepower, but it is not the only determining factor.

The acceleration ability is determined by the torque and the mass of the vehicle, and the torque is the force multiplied by the force arm

In addition to horsepower acceleration and so on, handling is important in the performance of the car. Because when the rules define the amount of horsepower mass and exhaust, the handling is decisive. That is, the car is not well controlled, and better control will have more speed when cornering.

The rotational speed is just a ......The amount of natural occurrence, because the torque is not the same at different speeds, so in order to ensure the torque, it is necessary to add a transmission to ensure that the speed of the vehicle is maintained within a relatively large torque range, so there is an upper limit on the speed. The general car is only 9000 rpm, and the actual use is 4000 rpm, and the rest are basically used ...... when racingF1 is a two-stroke engine, so the revs will be high

The F1 engine accelerates from 0 to 100 km/h in seconds; The maximum speed of the engine can exceed 19,000 rpm; With just a little longer distance than a tennis court, it can reduce the speed from 300 kilometers per hour to 60 kilometers per hour ......And these jaw-dropping stats are just a test of Formula 1 racing.

Super engine.

Every car in Formula 1 has a super engine. At present, the FIA stipulates that the displacement of Formula 1 racing engines is limited to 2400cc, which is an eight-cylinder engine in a V-shaped arrangement, so the displacement of racing engines is set at 2400cc.
