Many cars now have an automatic start-stop function, and it is often turned on by default. Whenever we wait for a traffic light, or a short stop, it will put the engine in a state of stoppage, when the driver releases the brakes to start or press the accelerator to start, it will automatically ignite, and the vehicle can continue to drive. However, some people like this function, some people will not like, understand the brother really do not like this function, for some low-end models, the vehicle will feel the body shake will be larger when starting in the car, and there will be a larger noise, the sense of experience is actually not good. Although some of the more high-end models will be better suppressed by the starting sound and body shake, sometimes when there is a traffic jam, there will still be a certain frustration when stopping and stopping, and frequently turning off the ignition.
Why install a start-stop system? Due to the increasing tightening of environmental protection regulations, there are stricter requirements for the models produced by various car companies in terms of emission standards and fuel consumption standards, and the fuel consumption of vehicles is higher than that of driving when idling, so turning off the engine when idling can indeed save a lot of fuel consumption. Vehicles equipped with start-stop systems can save up to 5% of fuel under normal road conditions, and up to about 15% in congested sections. According to authoritative tests, the use of this technology will save 10% to 15% of fuel per year for an ordinary car.
Start-stop damaged engine? In addition to the poor sense of experience, many people will worry about frequent starting and stopping the engine, whether it will cause damage to the engine or increase the wear of the engine. According to the current engine technology, the start-stop function will not actually cause damage to the engine and aggravate the wear, the engine caused more than 80% of the wear is generated during the cold start and operation of the engine, after a long period of parking, the oil will flow in the oil pan position at the bottom of the engine, and because of the low temperature, the oil viscosity is high, the fluidity is not good, so when the cold start, due to insufficient internal lubrication of the engine, it will cause wear to the engine. The state of activation of the start-stop function requires the engine temperature to reach the working standard, and the temperature set by the air conditioner in the cabin does not require the compressor to be strongly cooled to meet various conditions, and the vehicle will open the start-stop function. When the engine is hot started, the organic oil of the internal parts is fully lubricated, and the wear of the engine accounts for less than 20%, so there is no need to worry about the start-stop function will hurt the engine.
Start-stop damage battery? Vehicles equipped with start-stop functions need to use batteries with start-stop functions that are more advanced than ordinary batteries, and general batteries cannot be used. The battery is also a consumable on the vehicle, the price of the start-stop battery will be more expensive than the general battery, and the general light use of the start-stop function is not much harm for the battery with the start-stop function. However, if the start-stop function is frequently used, and there are more power facilities in the car, the battery may be in a state of power loss for a long time, and the life of the battery will be greatly shortened.
When must I turn off the start and stop? When driving in the rain, be sure to turn off the start-stop system, especially in the section of the road that is prone to water accumulation. In general, when the vehicle passes through the water, as long as the depth of the water does not exceed the engine and the air intake, it can still pass. However, if when passing through the waterlogged road section, the stop-stop function is activated to turn off the engine of the vehicle, and then the brake is released to ignite the vehicle, the water will be sucked into the engine, causing the engine to enter the water and scrap. Therefore, when passing through the waterlogged road section, or when driving in the rain, be sure to turn off the start-stop function.
If you are also like me, I think the experience brought by the start-stop function is indeed very bad, and I don't need this function, and I don't want to press the close button after every time I get on the car, some models can brush the way to hide the function, get on the car by default to close the start-stop function, if there is a need, then press the switch to open this function. It can be achieved by using computer brushes to hide them, which are generally used in most European car series.
If the Japanese car wants to turn off the start-stop function, some models can not be closed by the computer brush hidden way, you can also buy a multi-functional OBD plug, plug in the vehicle OBD interface can achieve the start-stop shutdown memory function.
