The speed is 120 per hour, and the engine speed is 3800 rpm, is it normal?The maintenance master will answer
The driving speed and engine speed of the vehicle are important parameters in the operation of the car, and it is important for the owner to know the normal range of these parameters. This article will analyze the engine speed of up to 3800 rpm at 120 km/h, and ask an experienced maintenance master to answer this question for us.
First: vehicle driving parameters.
120 km/h is undoubtedly a higher driving speed, and the speed limit on most highways will not exceed this value. However, there is a relationship between the speed of the vehicle and the engine speed, that is, the higher the driving speed, the higher the engine speed. Generally speaking, it is normal for a car to have a high engine speed when driving at high speeds. However, the so-called "normal" needs to be evaluated in combination with other factors.
Second: the influencing factors of engine speed.
Engine speed is affected by a number of factors, including speed, gear, and driving resistance. When the vehicle is driving at high speeds, in order to maintain a speed of 120 km/h, the engine needs to generate more power, so the rev speed will increase accordingly. In addition, factors such as driving resistance and road conditions will also have an impact on the engine speed, making it possible to further increase the engine speed.
Third: the normal range of engine speed.
For most cars, the normal engine speed range is generally between 1500-3000 rpm. However, some high-performance, high-powered models may have engines that rev more than 3,000 rpm at high speeds, but they usually don't exceed 4,000 rpm. Therefore, an engine speed of 3800 rpm can still be considered within the normal range in most cases.
Fourth: Consider anomalies.
While an engine speed of 3,800 rpm can be considered normal in some cases, there are other anomalies to consider. An abnormal engine speed may indicate a problem with the engine or that it needs to be repaired. Therefore, if the engine speed of the vehicle continues to exceed a certain range (such as 4000 rpm) when the vehicle is driving at high speed, or other abnormal conditions (such as abnormal noise, shaking, etc.), it is necessary to find a professional technician to check the vehicle in time to avoid potential safety hazards.
Fifth: Ask the maintenance master for his point of view.
In order to provide readers with authoritative answers, we interviewed an experienced maintenance master. He said that under normal road conditions and vehicle conditions, at a speed of 120 km/h, the engine speed of 3,800 rpm is within the normal range. Although the revs are slightly higher, there is no noticeable effect on the vehicle. However, he also reminded us that car owners should maintain normal driving habits during daily use and avoid driving at high speeds for long periods of time to prevent engine failures caused by excessive wear.
Conclusion: According to the above analysis, the engine speed of up to 3800 rpm at a speed of 120 km/h can generally be considered normal. However, we can't completely ignore the existence of abnormal conditions, so when other abnormal conditions occur in the engine, it is necessary to seek help from professional technicians in time. Finally, as car owners, we should maintain the normal use and maintenance of the vehicle to improve the safety of driving and the longevity of the vehicle.
