The car drives every day, but have you noticed the engine speed? Let's take you to know the speed of the car engine!

What is the appropriate engine speed?

The general speed is also between 1000 ~ 3500. The engine output torque is the maximum at about 3000 rpm, and then it is inversely proportional to the speed. Therefore, the general driving speed is about 3000 rpm. The higher the engine speed is, the more work is done per unit time, so the higher the power is, but the higher the speed is, the faster the whole cycle speed is, and the fuel is discharged without enough time for complete combustion. Therefore, the fuel consumption will increase several times. So the higher the speed, the better. The speed depends mainly on the speed and gear. It's enough to maintain it at about 3000. At this time, the engine has the greatest strength. In addition, avoid low-grade high-speed and high-grade low-speed, which are harmful to the engine.

What's the best engine speed?

1. When the idle speed of the ignition engine is lower than 800 / min and higher than 1200 / min during cold start, it should be noted that this is the performance of poor engine working conditions.
2. Try not to let the engine work below 2000r / min when the vehicle is running, because if the speed is too low, the engine will feel insufficient power. If the load of the engine is too large at low speed, it will damage the engine and easily form carbon deposition
3. When the engine operates above 400or / min, the fuel consumption will increase significantly due to the short combustion time and insufficient fuel combustion. If the fifth gear is used for normal driving, the speed can generally reach 150km / h, which has reached a more dangerous speed.
4. The engine working at 2200 ~ 3500r / min is the most economical and the best working condition of the engine. The speed of the car should be kept within this range as much as possible.
If the economy is considered when driving, it is generally more fuel-efficient to drive at 2500-3200 speed. For power, use low gear and high speed for acceleration, generally 4500-5000 rpm. More than 5000 engines are bad and consume fuel.

Now you should know something about the appropriate knowledge of engine speed! Car maintenance network Xiaobian reminds everyone to pay attention to safety when driving! Don't be a little careless.
