The engine is the most important component of the three major parts of the car, and the performance and durability of the engine will directly affect the driving experience of the car. When buying a car, many car owners will focus on understanding the power parameters and practical performance of the engine, and the speed of the car is a mirror that reflects the strength of the engine.
What kind of engine performs better? Go for a spin at high speed and observe the speed of the engine to solve the puzzle. Different displacement engines have different power, we can maintain a driving speed of 120 kilometers per hour at high speed, and the lower the speed, the better the performance of the car.
According to the operating state of the engine, when the vehicle maintains a certain speed, the greater the torque, the lower the speed of the car. The power gap between the 2.5T engine and the 1.5T engine is large, and when the two cars maintain a speed of 120 kilometers per hour, the speed of the 2.5T displacement car must be lower than that of 1.5T.
When a 1.5L displacement family scooter travels at a speed of 120 km/h on high speeds, it revs between 2500 and 3000. The 2.0L Toyota Camry travels at a speed of 120 km/h at high speeds, with engine speeds ranging from 2300 to 2600.
The 2.0T Volkswagen Magotan travels at a speed of 120 km / h at a speed of 1800 to 2200. The Cadillac, equipped with a 2.5T engine, only travels at 1700 to 1900 rpm at 120 km/h at high speeds.
From these data analyses we have come to the conclusion that a car with a larger displacement has a lower engine speed when driving at a fixed speed at high speeds. When everyone runs at a high speed of 120 kilometers per hour, the speed exceeding 2500 indicates that the performance of the vehicle is average, and the speed exceeding 3200 indicates that the performance of the car is poor.
The vehicle runs 120 at high speed, and the car with a speed below 1500 has very good performance, and generally only a sports car can reach this level. Ordinary family scooters do not have to put forward such high requirements, the higher the speed, the greater the displacement of the car, the higher the fuel consumption.
If you buy a car just for family transportation, it is best to choose a 2.5L or 2.0T engine. These two displacement models run 120 rpm between 1800 and 2200 at high speed, and this displacement car can meet the power required for daily driving, and the fuel consumption will not be too high, and the cost performance is the highest.
Precautions when running at high speed:
First, control the speed of the car.
The road conditions on the highway are better, the traffic flow is very small, and the throttle is deeper and deeper when the owner runs at high speed, unconsciously exceeding 150. Speeding on the highway is full of dangers, it is useless to step on the brakes when encountering unexpected situations, 10 car accidents 9 times fast, I hope you can control the speed.
Second, keep your distance from the car.
It is very necessary to maintain the distance with the car when running at high speed, in case the front car brakes sharply, the rear car is not well controlled, and it is easy to cause rear-end collision.
Third, don't rely too much on cruise control.
Some car owners rely too much on ground speed cruising, and turn on constant speed cruise every time they run at high speed. Although the cruise control function is easy to use, it should also be cautious, this function can only be used as driving assistance, and the owner must concentrate on observing the road conditions.
Frequently pulling high speed helps to reduce car carbon deposits, I hope that everyone will run more high speed without violating traffic rules, and how much will your car drive to 120 rpm?
