Turbocharged engines run at high speed for four hours, do you have to wait a few minutes when you stop in the service area?
Yes, not only need to turn off the engine, but also need to cool it down, it is best to buy an air conditioning fan, use the air conditioning fan to blow the cabin, and then pour some cold water to take a towel to wipe the engine, and then buy a popsicle for the engine to eat, be sure to remember if it is an old Beijing popsicle.
This classmate you are really a car lover, are you anti-Japanese drama watched too much? Or is your mind stuck in the '90s? Current family models, whether self-priming or turbocharged, do not need to deliberately worry about the failure of the vehicle for a long time, rest assured, your car is more resistant to construction than the driver.
The load of running a high-speed car is not large
Many people have a misunderstanding, that is, the car runs so fast, is the load of the vehicle relatively large? In fact, on the contrary, when running high speed, the engine speed is low, generally the highest grade, like the 2.0T engine, only need 1500-2000 rpm or so, 1.5T engine, about 2500 rpm, far from reaching the red line of the speed of the vehicle, but the urban driving because of the need for frequent start and acceleration and deceleration, the load of the car is greater. For example, if you ride a bicycle, driving in the city is like going uphill, pedaling for life, running at high speed is like flat ground + downhill, just step on a few stirrups.
The vehicle has a perfect heat dissipation system
General family cars have a complete cooling system, including water pumps, radiators, cooling fans, compensating water tanks, thermostats, water jackets in the engine body and cylinder heads, and accessories. When the vehicle is driving at high speed, the intake grille will pour into a large amount of air, basically do not need additional heat dissipation, even if the temperature of the engine is too high, the coolant will start to work, through the water pump into the engine to dissipate heat to the machine. Fans at low speeds and idle in place will also help dissipate heat according to the temperature of the engine, including the turbo delay cooling system of turbocharged models, so the general vehicle will not overheat the engine when the coolant is sufficient.
Vehicles leave the factory undergoing durability tests
All models have to be tested for durability before leaving the factory, generally 40,000 kilometers of structural durability and 400,000 road simulation tests, and some also have to carry out 1,000 hours of uninterrupted operation tests or high-speed tests of more than 15 hours of rotational speed in the red line area, which are much more extreme than the high-speed conditions you run for several hours.
Therefore, instead of worrying about the overheating problem of the vehicle running for several hours at high speed, it is better to worry about whether the driver is tired of driving, letting the driver stop in the service area to rest and rest is the right thing, blindly worrying about what, the car is more durable than the driver, how long you can drive, how long the vehicle can run, but still remember not to fatigue driving.
