Car self-start-stop function, strictly speaking, it is also called engine automatic start-stop technology, this technology actually appeared as early as the 30s of the last century, in the 70s, Toyota had done a similar test on the Crown sedan, the test results showed that the fuel saving rate increased by 10%, the trigger mechanism is when the car stops 1.5S, the engine will automatically turn off!
Then, Mazda also developed the i-Stop system, and then more and more models began to apply this technology to their own vehicles, including some Of the German brands and French brands we are now familiar with, for now, due to the control of environmental treaties, more and more car companies have also joined the ranks of engine self-start and stop, and also called it: "energy saving and emission reduction, reducing fuel consumption!" ”
In fact, according to the reason, the engine self-start-stop technology does have this effect! Especially for car owners who use large displacements and often pass through congested road sections, it is indeed a big cost. China Automotive Technology and Research Center and Bosch in Germany have also done special tests on engine self-start-stop, and the results show that the test subjects using automatic engine start-stop technology have obtained different degrees of fuel saving rate!
In this way, the advantages of engine self-start-stop technology are still good! However, it should be noted that there cannot be a perfect technology in this world, and there will definitely be disadvantages to the advantages! If you want to get something, there must be something that one party needs to pay!
Obviously, the paying side is our engine, the engine starts frequently, and the number of wear and tear caused to the engine must be more, but this is actually not its disadvantage, because the engine self-start-stop function is generally used to stop again after the vehicle has been driving for a period of time, which means that the engine at this time is hot start, the wear of the engine will not be very large, the old drivers should know that the car will cause maximum wear to the engine when it starts cold, right? So the paying party is not from the engine, where does it come from?
In fact, the party that pays for this comes from the engine-related components, that is, its starter and battery, the starting principle of the engine is that the battery transmits electrical energy to the starter, the starter generates mechanical energy after moving, and then transmits the mechanical energy to the engine, and the engine begins to realize the real operation!
Therefore, it is false that frequent starting of the engine will cause great loss to the engine, and it is true that the loss caused by the starter and the battery is true! Of course, although some car companies in order to reduce wear, has tried to use enhanced starters and batteries, but the loss is after all a loss, despite this, with the engine self-start-stop function of the vehicle, their starter and battery failure rate are higher than the engine self-start-stop function vehicles, of course, the starter and battery maintenance costs, as well as the quality of the oil, etc. are going to rise, which means that the maintenance cost is also to be improved!
Write at the end
In fact, as far as I am concerned, the view of the function of engine self-start and stop is that it is available for models that have passed the technical pass, and models that are not technically passed are still good to use cautiously! Here to share a personal experience, when in Chengdu to do business, to the local to rent a car (specific which car is not to say), this car is with the engine self-start-stop function, but when driving to the congestion section of Chengdu, I found the problem, when I stepped on the brake, the engine self-start-stop function intervened, congestion lifted, when stepping on the accelerator to walk, it actually retreated, at that time can scare me not lightly, and then I decisively turned it off!
However, as far as normal vehicles are concerned, the engine self-start-stop function is still more convenient, for example, when you are waiting for traffic lights, the waiting time is relatively long, and the engine self-start-stop function intervenes, at this time it is YYDS! So in different cases, turning on and off the engine self-start-stop function will make you get an unexpected driving experience, after all, it is also fuel-efficient!
Finally, I would like to leave you with a question for discussion, what is your opinion on the self-start-stop function of the engine?
