Now many 100,000-level cars have been equipped with automatic start-stop function as standard, automatic start-stop refers to the car brake after braking hard, the driving computer will automatically turn off the engine and pull up the handbrake. The owner will start the engine by tapping the throttle again, and the handbrake will automatically be lowered.
The function of automatic start and stop was previously only available on high-end cars, but now this function has become an entry-level configuration for domestic cars. Is the auto-start-stop function really easy to use? Some car owners are tired of automatic start and stop during driving, and they have to turn off this function as soon as they get on the car.
Advantages of automatic start-stop:
First, save fuel. Traffic jams are often encountered in big cities, and cars are particularly expensive when they stop and go. The automatic start-stop function can temporarily shut down the engine, saving some fuel.
Second, energy conservation and environmental protection. During engine start-up, even idle speed emits large amounts of sulfides, carbon monoxide and nitrogen oxide. These exhaust gases pollute the air and with the automatic start-stop function, exhaust emissions can be reduced.
Since the automatic start-stop energy saving and fuel saving, why do many car owners turn off this function as soon as they get on the car?
First, the engine starts frequently.
During the parking process, the owner will frequently step on the accelerator and brake, and the automatic start-stop function of many cars is too sensitive, and the owner will turn off the engine when he gently steps on the brakes. When the owner parks in the parking lot, every time the engine is moved tens of centimeters, it will restart once, which is particularly inconvenient when parking.
In the rush hour of commuting in large cities, the traffic jam phenomenon is very serious, when the traffic jam is parked, if the automatic start and stop function is too sharp, the engine will frequently turn off and start. The owner's mood is already very irritable when the traffic jam is stuck, and the frequent engine shutdown will only make the owner more disgusted.
Second, it affects the operation of air conditioning.
In winter, the temperature is low, and it is best to turn off the automatic start-stop function when the owner starts the cold car. Because the air conditioner in the car is driven by the engine, when the engine automatically turns off, the air conditioner is no longer refrigerated and heated, and the automatic start-stop function will affect the normal operation of the air conditioner.
Third, damage to the car battery.
Many car owners are worried that turning on the automatic start and stop, the frequent shutdown and start of the engine will damage the engine, in fact, the damage is not the engine but the battery. Frequent shutdowns and ignition of vehicles can lead to a shorter battery lifespan.
Fourth, damage the engine when wading through water.
When driving on the ground with accumulated water on a rainy day, it is best to turn off the automatic start-stop function. In case the engine suddenly stops when the vehicle is wading through the water, the owner lightly presses the accelerator and ignites the engine again, and the air pressure generated by the engine will attract rainwater into the engine, resulting in engine damage.
The original intention of the car company to invent the automatic start-stop function is good, this function will indeed reduce fuel in the daily use process, but the owner must use the automatic start-stop must be divided into occasions.
The owner of the car is driving in a traffic jam, and the automatic start-stop function must be turned off in advance when the vehicle is stopped and stopped. The vehicle stops on the ramp, or when the car is stuck on the ramp, the automatic start-stop function should also be turned off, otherwise when the engine is started again, the vehicle may slip for a short time due to gravity.
Usually driving in the urban area, as long as the road is not congested, the owner does not need to turn off the automatic start-stop function. The automatic start-stop function when waiting for traffic lights for a long time can indeed reduce some fuel and improve the fuel economy of the engine. Do you think the automatic start-stop function is easy to use?
