Please ask Mr. Fei, I heard that hybrid vehicles are prone to oil emulsification, is this so? Will the range-extender hybrid also?
A - Theoretically, the engine of a hybrid is indeed more prone to oil problems, and range extended hybrid is no exception. The reason is also very simple, compared to the normally open state of the pure fuel vehicle engine, the hybrid engine is not always in the working state, so it is more difficult to maintain the operating temperature, which will lead to exhaust gas recirculation or insufficient ventilation of the crankcase, which will cause gasoline condensation into the lubrication system.
Of course, specific to the process of using the car, manufacturers will also take into account this aspect of the problem, strengthen the warmer, and shorten the cycle of oil change, and for users, usually drive as much as possible to be grumpy, as far as possible to maintain the engine operating temperature is also an effective means. Off-topic, individuals do not recommend choosing a range extender hybrid, not what advanced technology, can not do low power loss fuel consumption, pure pure IQ tax.
Talk about the economy, practicality, durability, cost of the car, and which cars are worth recommending for 60,000-80,000, SUVs, and sedans.
A-CS75 and Envision X6 are the main cost-effective products of their respective brands, perhaps you can not see the latest technology of their respective brands in them, the characteristics of this type of car is cheap + affordable. On the whole, CS75 and Vision X6 are more recommended for the former, the fuel consumption of the two vehicles is about 8L, and the cost of the late car maintenance is not too much, and the reason for recommending CS75 is that its ownership is larger and the driving quality will be better. At this price, Auchan X5 and Jetway X70 PLUS can be selected.
Hello teacher, BMW iX3 is said to be very good? Although it is an oil-to-electricity car, compared to those trams with cheap pure electric platforms, what is the better of this oil-to-electricity tram?
A - In general, the pure electric platform model in terms of layout and other aspects is naturally better than the "oil to electricity" or to be professional, iX3's three-electric system does not have any core advantages, the main competitiveness is that the driving quality is indeed very good, which is also a lot of domestic cars or some pure electric platforms generally lack of things. In addition, the price of iX3 is relatively good, in general, an electric car is priced higher than its fuel version, but in contrast, iX3, the terminal price is lower than the X3.
Hello, Teacher Fei, I would like to ask a question about the car refueling. Car fuel tank is recommended as long as you add more than 92 gasoline on the line, but friends around are generally add 95 oil, said that after adding, the car shakes less, acceleration faster and more sensitive, is there really such a thing or psychological effect? Colleagues said that after adding 95 oil once, they could not go back to adding 92.
A - This kind of thing, reasonable scoring car. In principle, if your engine optimization is done well, the technology is advanced, and you can run a high compression ratio, then adding No. 95 gasoline will indeed be more stable, but the acceleration sensitivity is indeed a bit ridiculous, because at large loads, the engine will increase the amount of fuel injected and reduce the compression ratio to obtain high power output.
Personally, I think that if the fuel tank cover is written above 92, then add No. 92, saving two packs of cigarette money is definitely more fragrant than the illusory experience improvement, really value the maintenance of the car, and should also be preferred to consider changing the fully synthetic oil, rather than upgrading the fuel label.
Q&A column is updated every working day, everyone has any questions about the car can be left below the column to ask questions (not the dialog box of the public number Ha, easy to leak), we will arrange the answer in order, no answer to please be patient, sometimes more questions will be ranked to the second or third day, keep an eye on it ~
