Remember "oil to gas"? In the New Year, the electric brother returned to his hometown and saw this familiar figure, which can be called the Renaissance.
Why coach cars and taxis regard it as a pearl in the palm of their hand;
Environmental protection, 0 emissions per kilometer as long as 3 cents;
Why did the king who once ran everywhere become more and more sparse on the road?
Behind all this, is it a distortion of human nature or a moral degeneration? Is it the regression of technology or the obstruction of capital? Stay tuned for today...
Seriously, in the past, when you take a driver's license and take a taxi, you will find the "big can" equipped with the trunk.
There is a saying that the unit price of natural gas is cheap and not polluted, and the most important thing is that there is no endurance anxiety, which is far more extended than the extender range, and it should be an invincible existence. But now, suddenly everyone is no longer using it, what is the reason for this?
The logic behind any behavior is mostly just for profit, the following is from the cost, efficiency, safety hazards and other aspects of the analysis, after reading you will understand.
First, it costs a lot of money, and the effect is still slow
Choose oil to gas, the core appeal is still cheap, but from the general compact car transformation cost, gas cylinders, wiring, supercharger a set of hardware to do down, generally to 5500 yuan up and down.
This belongs to the one-time cost, long-term use of the process, the average cost of natural gas per kilometer in the early 3 cents, of course, the price of gas will be a little different, of course, now the oil price is very expensive, according to 8.5L / 100 km of fuel consumption + 92 gasoline to calculate, 6 cents per kilometer up, but have to run 10,000 km to save 3,000 pieces.
High-intensity use of 2 years of pure burning gas, in order to barely save back the cost of modification, compared with the cost of hybrid and pure electricity, it is more redundant, tossing half a day turned out to be a headache to pat the butt - blind delay.
Second, trouble, is real trouble
The first step is to roughly sum the cost is very discouraged, the point is that the operating vehicles are now very formal, and individual users are not allowed to modify the fuel pipeline without permission.
Even if you have strong hands-on ability, it is indispensable to handle the core certificate and solve the problem of follow-up annual review.
Well, you can get these done, it is important to solve the problem of refueling, if it is not a large-scale operation of vehicles, it is difficult to do regular refueling, the volume of the gas tank after the transformation of our ordinary compact sedan is generally more than ten liters, pure combustion gas can only adhere to 200 kilometers, suddenly found that this is more than the endurance anxiety of electric vehicles, minus the round-trip replenishment loss has been left.
If it is a city along the north-west gas-to-east gas transmission line, it may be slightly more convenient to refuel. Not to mention that after burning the gas, you still have to burn the oil, which is the mysterious button of "one-click switching". Then why not directly carry this tens of pounds of gas tanks, directly burn oil it is not fragrant?
Third, the experience is average, and there are safety hazards
We all know that there will be a certain proportion (about 10% or more) of the loss of the burning gas power, which is also the reason why we always feel that the car is "boring" in the early years when we practice driving school, and we always remember the fear of being dominated by the start of the half slope. The gas tank itself also has to add extra loads to the entire car.
Therefore, in the normal use process, it is easy to "die the fire", to increase the speed.
It must also be noted that the consumption of burnt gas on the consumables of the fireworks plug is very large, and it must be replaced basically every year.
And everyone can't remember the previous training, the car NVH is also very affected, it seems that it is always very "shaky", so the throttle basically has to be washed once a year.
After all, the combustion gas has changed the original intention of the design of the internal combustion engine, the combustion chamber temperature is high, the life must have an impact, and it must be in the compression ratio and other parameters, which cannot meet the design requirements.
We carry an atmospheric tank every day, although this compressed natural gas, the pressure is not particularly terrible, but there are still leaks and other risks, once a rear-end or open fire, even if not, burning up is certainly no problem, think about the heart always feel worried.
Fourth, the efficiency of CNG is too low, and LNG is suitable for operating vehicles
The private cars just mentioned are CNG, that is, compressed natural gas, which itself needs high-pressure storage, not to mention, the volume energy density is still at the bottom, only less than 1/3 of gasoline.
In addition to taxis, large commercial vehicles such as buses will be more suitable, after all, the storage space is abundant, the operating routes are very fixed, and it is more convenient to refuel.
However, these large commercial vehicles use more LNG, that is, liquefied natural gas, which is safer, and the volume energy density is 2/3 of that of gasoline and there is change, which is much more efficient. Of course, LNG pretreatment is more difficult, storage requirements are higher, but LNG is a more stringent sense of clean energy, so we can still see many bus lines choose LNG system.
However, with the rapid development of power batteries, unless the northern environment temperature constraints, now large bus pure electrification is also the mainstream.
Fifth, finally, it is the dimensionality reduction strike of real new energy vehicles
First put aside the electricity must eventually replace the fossil fuel these macro level things, pure electric vehicles, whether it is driving experience or use cost, compared to the combustion gas is a dimensionality reduction blow, electric drive is very direct power responsiveness, quietness are much better, there is electricity than gas cheaper, more stable.
Whether it is for operating vehicles or private vehicles, the convenience of electrical energy replenishment is much better than refueling. At the same time, the power battery is in a very exuberant period of technological iteration, such as semi-solid-state, solid-state batteries and other technologies emerge in an endless stream, every one or two years with the same specifications of the battery pack life to increase by more than 100 kilometers, directly approaching the gasoline internal combustion engine model.
Charging also has a variety of ways such as slow charging, fast charging, and power exchange, compared to natural gas has no slight advantage, not to mention the consumption of parts, maintenance cost gap is huge, maintenance fees can further reduce the cost performance of burning gas.
To a large extent, fossil fuels are irreversible resources after all, and electric energy itself is pure clean energy, power generation channels are also diversified and more and more clean, from 2010 to 2020, China's clean power generation accounted for from less than 5% to nearly 30%, and with the backward thermal power de-capacity and clean power generation in various places to increase rapidly, this trend will continue to rise rapidly.
At present, electric energy can not be convenient transportation and storage, from the economic and environmental protection point of view, the surplus electricity, through large-scale industrial production into hydrogen is also much more reliable and efficient than the direct use of natural gas, itself hydrogen and electricity natural also have better complementary characteristics.
No matter from the cost, efficiency, safety hazards at all levels, it seems that natural gas models do not have the inevitability of existence, let alone oil to gas.
It is not difficult to see that the transformation of oil into gas has become a historical process, and it is indeed an inevitable choice.
