In recent yearsNew energy carsThe heat has been high. A lot of friends change cars around, and the first reaction is to give priority to pure trams. The power of electric cars is cheap, and they drive quietly and smoothly. But there's a real problem. It's always stopping people from buying cars: the neighborhood can't fitCharge stakesI don't know。
The absence of fixed spaces, the exclusion of property from loading, and the inadequate load of old circuits are common. It takes time to rely on external public recharge poles, line up during peak periods, float electricity prices, run round and round, and long-term calculations reduce the cost advantage of motor vehicles. Many families find themselves in a dilemma: trying to buy a low-cost walker without having access to a tram; continuing to choose traditionFuel truckThere are concerns about high oil prices and the daily cost of commuting。
Against this background, a number of new fuel trucks and high-efficiency hybrids slowly entered the public eye, and many found that the tankers appeared to have a quiet turn-off. It's clear here that not all tankers can afford to be low-cost, but a group of main playersLow fuel consumptionThe type of car, which puts the cost per kilometre at a very low level, makes it possible for some of the next kilometre to be around 20 cents, which is suitable for ordinary households that are not charged with a pedestal and are not easily charged。
Many questions arise in the first place: oil prices have fluctuated and how do tankers reach 2 cents a kilometre? Let's start by accounting for the costs, not exaggerating, not fabricating, in a way that ordinary people can understand。
First, we set reference conditions, domestic price 92 gasoline, and we take the common daily range of 7. 5 yuan/l as the baseline. Simple conversion: 2. 7 ÷100 x 7. 5 = 0. 2025 kilometre, i. E. Almost 1 kilometre of 2 cents per km, if the combined fuel consumption of a vehicle is controlled at 2. 7 litres per 100 km. Many people find it incredible to see this fuel consumption, with the traditional old sedan driving at 6 to 8 litres, and suvs even higher。
It's not an old fuel car, it's a new generation of fuel-efficient, non-plugged powerMixer modelI don't know. Many people are easily confused with ordinary oil. Interpolation can charge the poles outside, close to the trams when they are available; and the models we are talking about today, which do not need to charge the stakes, are fuel-driven, rely on engine optimization, mix the system to work together, reduce fuel consumption, and run directly without chargeting, and without recharging, without continuing anxiety。
It must be objectively stated that 2. 7 l/100 km is the ideal combination of fuel consumption, mostly urban smooth and smooth driving. If there is frequent traffic jams, frequent parking, full loads or high-speed driving, fuel consumption increases and costs increase. Most daily commuting scenarios, with combined fuel consumption of between 3 and 4 litres per 100 km, cost approximately 0. 22 to 0. 3 per km. Compared to the average fuel truck, which consumes 7 litres per 100 km, the same price of $7. 5 per km is more than $0. 5 per km, leaving the gap wide open。
Now, let's talk about the low-fueled cars, which families, which people will step on the pits and find the right location。
Priority is given to families who are not in a position to install household chargers. This is also the focus of the article. Many of the friends who live in old neighbourhoods, rented houses, parking spaces are temporarily shared spaces and want to get on a tram or plug in, and the hardware conditions are not supported. Public charging stakes are unevenly distributed, with even fewer in peri-urban areas and towns. The time cost is high if there are dozens of kilometres of daily commuters and frequent charging stations. Such low-fueled hybrids, which need only a gas station to be replenished, have a high national coverage, do not have to plan the recharge route in advance, refuel in three or five minutes, and have a consistent usage pattern for traditional tankers, with low learning costs。
Second, users who often travel long distances across the city. The long journey of pure trams, the advance planning of charging stakes, and the queuing of holiday high-speed charge stakes is a familiar problem. Such non-charged hybrids, long-distance travels require only normal refuelling, without the distress of power decay and cold runoff. In winter, when fuel consumption increases slightly, it does not continue like a tram, and northern users feel more clearly。
Thirdly, with a limited budget, users seeking to stabilize their minds. Many people buy cars that do not want to cause complex battery maintenance and battery decay. Non-interpolated hybrids have no large-capacity power cells, which are small and are used primarily to support the drive and to recover brake energy. The structure is mature, maintenance processes and common fuel vehicles are close to each other, and the high cost of replacement of late large-capacity batteries is not covered. For those who want to stabilize their steps, who don't want to develop recharge strategies and who are concerned about the cost of battery maintenance, it is much easier。
Let's talk about the wrong crowd and avoid the blind. If you already have a charger in your home, a day-to-day shuttle short-distance, easy to charge, a pure tram or plug-in, the overall cost of use would probably be lower, and there would be no need for hard selection of low-oil vehicles. If you are more aggressive in driving and like to drive fast and often over the country, the main fuel-saving vehicle type is soft, it is difficult to get low fuel consumption, and a kilometre of low cost is difficult to achieve. Moreover, it is difficult to meet the demand for heavy-powered, large-space hard-core suvs, which are mostly of a domestic, compact car or small suv type。
A central concern for many readers is how low fuel consumption can be achieved. It's not some kind of black technology, it's the result of a combination of technologies。
First, the heat efficiency of the engine itself increases. Previously, many domestic engines had only about 35 per cent heat efficiency, and now a new generation of atkinson cycle engines can achieve more than 40 per cent heat efficiency. A simple understanding is that the same litre of gasoline can transform more energy into a driver, less heat is wasted and fuel consumption decreases naturally. However, these engines are self-absorbed with weak motor characteristics and use alone to drive meat, so they are generally combined with mixing systems。
Second, the energy recovery system. When vehicles are slowing down and brakes are stomped, the traditional tankers transform the kinetic energy into heat consumption. The hybrid vehicle type will recycle this part of the kinetic energy to small batteries, which will be electrically driven as they move at low speed, and the engine will try to avoid the low speed zone with the highest fuel consumption. Urban blockages, which have the most visible effect on fuel savings, are also key to low fuel consumption for urban commuters。
Third, power logic optimization. Low-speed electric power, flat-speed cruise engines, and fast-track oil and electricity were used together. The computer automatically determines the road transition mode and the driver does not operate manually. The engine can be shut down when there is a traffic jam, and it can only slide by the electric engine, avoiding long periods of impurities。
Fourth, lightweight, low wind resistance design. Many of the new ones are fuel-efficient, have optimized body materials, chassis structures, better control of the overall weight of the vehicle and have reduced high-speed wind resistance and further pressure on fuel consumption. Tyres will also be accompanied by low-roll-back tyres, which will reduce wear and tear。
Having said that, we compare objectively three types of vehicles: pure electric cars, conventional fuel trucks, low-fuel hybrid vehicles that do not have charge-free requirements, so that everyone can choose among themselves。
First look at pure trams: where there are private stakes, the price of electricity in the valley is cheap, the cost of a kilometre may be as low as 5 minutes to 1 cent, and the cost of using the car is the strongest. Shortboards are dependent on charging stakes, unlicensed users rely on public stakes, expensive electricity, queuing time, shrinking water in winter, long travel concerns, and battery decay and replacement costs are long-term concerns。
Traditional fuel vehicles: easy to refuel, many models and a lot of power options. Shortboards are high fuel consumption, with a common ratio of 6 to 9 litres per 100 km and high long-term transportation costs. The technology is mature, but the cost of using a car is not advantageous。
Uncharged mixed oil tankers: no recharge stakes, refuelling supplies, low combined fuel consumption, and normal commuting costs of 2 to 3 kilometre. Fuel costs are higher than those for electric cars; high-speed, rapid and sustained acceleration will reduce the advantage of fuel; the purchase price and configuration of vehicles, which are often more expensive than ordinary fuel trucks, will need to be driven over a long period of time to save the difference from the oil. Here it is recalled that the difference in the price of cars is an easy one for many to ignore. For example, the difference between the same vehicle type, common fuel version and hybrid version is 15,000. If it takes 10,000 kilometres per year, 0. 2 dollars per km of province and 2,000 dollars per year, it takes more than seven years to return to the capital. It would be more cost-effective to directly select the general fuel version if there were very few miles to travel each year, three or 5,000 kilometres a year, saving savings and making it difficult to cover the difference in the purchase price。
This is a very critical logic of calculation, and the purchase of vehicles cannot be based solely on the cost per kilometre, but also on annual mileage. A lot of sales will only tell you how cheap a mile is, and it won't help you get back to the cycle. When you pick a car, you have to judge how many kilometres you run each year。
In addition to the cost of fuel, there are other items, such as insurance, maintenance, repair and depreciation, which are described briefly。
With regard to insurance, the premium is slightly higher than that of a car equipped with pure fuel, owing to the presence of batteries, and the difference is not particularly large and is far lower than the increase in the premium for a car that is pure and interpolated. Upon maintenance, the engine maintenance line is the same as the normal fuel truck, and oil, machine filters and filters are replaced on a cycle basis. Small-capacity hybrid battery manufacturers generally provide longer quality assurance cycles, normal household use and lower risk of battery failure during quality assurance cycles。
This component of depreciation preservation has steadily increased over the last two years, unlike the old mixed car second-hand relationship. However, some cold-door hybrid vehicles remain weak compared to mainstream fuel domestic vehicles. Friends who were planning to change cars in three or four years needed to know the local second-hand car in advance; the impact of preserving a car would be much smaller if they were to move for 8 to 10 years。
There are several practical driving techniques, not genres, that can be done directly。
First, to drive as smoothly as possible and to reduce the frequency of severe and accelerated brakes. At a time of rapid acceleration, both engines and electric generators work simultaneously and fuel consumption increases rapidly. Urban commuters, pre-empting road conditions, untying the gas doors and allowing vehicle energy recovery systems to work are the most efficient。
Second, it's hard to save fuel for short-distance cold cars. Just starting in the morning, the engine needs to heat up, and the cooler phase is fueled. If one or two kilometres of a single car were to be driven, the vehicle would reach its destination before it was hot, and fuel-saving car-type fuel consumption would increase significantly. It is not expected to be too high if such short steps are often made。
Third, reduce the additional burden. The long-term build-up of the trunks with heavy loads and upholstery should increase the driving load and fuel consumption. Tire pressure maintains the standard recommended by the manufacturer, the tire pressure is low, the tire rolls are high, and fuel consumption is equally high。
Fourth, high-speed conditions, no speeding. Wind resistance multiplyes after speeds exceeding 100 kilometres per hour, which is also the main reason for the marked increase in fuel consumption for many fuel-saving vehicles. The flat speed range of 90 to 100 km/h is the most economical of these types of vehicles。
When we talk about strengths, costs, people who fit, we also have to look rationally at the limitations of this type of car。
First, fluctuations in oil prices can have a direct impact on vehicle costs. If oil prices continue to fall, the gap between them and ordinary tankers will be narrowed; the value of oil savings will be magnified when oil prices rise. Its low cost is based on low fuel consumption and cannot be separated from oil prices by a single kilometre of 2 cents。
Second, the power correction is biased towards saving oil. In order to reduce fuel consumption, the engine is designed to be conservative and to start and accelerate the eruption at a low rate. A driver who's used to driving a chariot can feel light power。
Third, maintenance of network and spare parts coverage. Mainty large-brand hybrid system maintenance has matured, small brand hybrid vehicles, late maintenance spares are waiting time, maintenance costs are more uncertain, and the purchase of vehicles is preferred to high-tensure and after-sales brands。
Fourth, the long-term direction of environmental policy. Local emission policies continue to be updated, fuel vehicle-type future restrictions and phase-out rhythms differ from one city to another, and it is recommended that local emissions policies be updated before purchasing vehicles, avoiding old storage vehicles。
In combination, the greatest value of such low-fuel hybrid vehicles, which are not charged, is to fill the low-cost step gap for families without charge stakes. The choice had been to polarize: there was a train to save electricity, and there was no more than a traditional one. There is now an additional option to keep the daily shuttle fare at a very low level without changing refuelling habits or placing charge points, which is at the heart of what many people say is a chance for a tanker to turn around。
It does not replace the tram, nor does it mean that all the tankers are worth buying, but provides a new option for families with specific needs. Would it be appropriate to finally return to three questions: can we charge the stake at home? How many kilometres per year? Can't you accept a smooth power style
Buying a car is a long-term expense, and should not be moved by the figure of “two cents per kilometre” alone, first to calculate the difference in the purchase price, then to return to the current cycle, and then to make its own decisions in relation to the scene. It's not always for yourself。
Finally, i'd like to ask you: do you have any conditions to charge the stakes? If you don't have a private stake, do you prefer low-fuel hybrid cars, or do you continue to think about pure trams, plugs? What's the cost of a kilometer of your daily commute? Welcome to the comment section about your use of the car, interested in asking for attention, and to continue to share the real, ground-breeding, car-calculation content to help avoid the car selection。
