As we all know, the engine is the heart of the car, and the speed is the working state of the engine. So, what exactly are the factors that affect the speed limit of the engine?Let's talk about this topic in more detail.
It is important to know that the limit of engine speed is not a fixed value, but is influenced by a variety of factors. For example, one of the most common factors is the displacement of the engine. Generally speaking, the larger the displacement of the engine, the higher the speed limit. This is because engines with large displacements require more air and fuel to keep them running, and these need to be achieved at higher revs.
In addition to displacement, the engine speed limit is also affected by the compression ratio. The compression ratio refers to the degree to which the air in the cylinder is compressed, and the higher the compression ratio, the higher the pressure and temperature in the cylinder. In this case, in order to prevent the engine from deflagrating or overheating, the speed limit is lowered accordingly.
The engine speed limit is also related to the ignition advance angle. The ignition advance angle is the angle between the ignition moment and the top dead center of the piston. If the ignition advance angle is too large, it will lead to deflagration or overheating, thus limiting the speed limit of the engineOn the contrary, if the ignition advance angle is too small, it will lead to insufficient engine power and weak acceleration. Therefore, in order to achieve the best ignition time, we need to adjust according to the actual situation.
In addition, the engine speed limit is also affected by many factors such as the lubrication system, cooling system, valve train, etc. For example, if there is a problem with the lubrication system, it can lead to increased friction and limit the speed of the engine;If the cooling system does not remove the heat in time, it will cause the engine to overheat, which will limit the rev.
According to the above, there are many factors that affect the engine speed limit, and these factors are also interrelated. Therefore, in actual use, we need to comprehensively consider various factors and reasonably adjust the working state of the engine to achieve the best performance.
I would like to remind you of this: don't blindly go for high revs and acceleration. While these can give us a short-term euphoria, overuse can cause irreversible damage to the engine. Therefore, we should use the engine reasonably according to the actual situation when driving, so that it is always in good working condition. Only in this way can our car stay with us for a longer time.
