What are the advantages and disadvantages of burning oil and steam in automobiles?

Comparison of the advantages and disadvantages of burning gas and burning oil.

Merit. Economic benefits.

Higher. Natural gas is easy to mix evenly with air in the engine, and the combustion is relatively complete, clean, and not easy to produce carbon deposits.

Good anti-knock performance, will not dilute the lubricating oil, so that the wear of parts in the engine cylinder is greatly reduced, can prolong the life of the engine and the service life of the lubricating oil.

Social benefits. Good. Compared with petroleum fuels, gaseous fuels have less energy loss and less harmful emission pollutants in the preparation process, which is more beneficial to environmental protection.

High level of security. A slight leak in the natural gas itself can quickly spread into the atmosphere, and the various components of the gaseous fuel system, especially the sealing sections, are rigorously inspected. Therefore, natural gas is relatively safe as a fuel for automobiles.

Natural gas is easy to mix evenly with air in the engine, and the combustion is relatively complete and clean, and the anti-explosion performance is good. On the other hand, gaseous fuels have less energy loss and less harmful emissions of pollutants in the preparation process, which is more beneficial to environmental protection. For the majority of car owners, the biggest benefit of "oil to gas" is that it can save money.

Hefei's industrial and commercial gas ** is yuan cubic meters, and No. 93 gasoline ** is about yuan liters. Based on the ratio of natural gas energy equivalent to 1 liter of gasoline per cubic meter, the cost of using natural gas as fuel is more than half that of gasoline. According to a survey of taxi drivers in Hefei, the cost of gas per kilometer of natural gas is about yuan.

In any case, the savings from "oil to gas" are significant for those vehicles that are used more frequently.

Shortcoming. Due to the energy density of gaseous fuels.

Low, natural gas cars.

It carries less fuel and has a shorter mileage than a gasoline car. And the natural gas engine used is mostly made of gasoline engines.

Modifications, so the power of gasoline cars tends to drop by about 10% to 20% after switching to natural gas.

Since the natural gas vehicle is modified on the basis of the original gasoline and diesel vehicles, the fuel system of the original gasoline and diesel engine is mostly retained. Therefore, it is necessary to add a natural gas fuel system to the original car, especially the gas cylinder, so that the effective use of the original car trunk space is reduced, and the self-weight itself is also increased.

Natural gas is a gaseous fuel that is not easily stored and carried. For this reason, it is necessary to pressurize or liquefy for bottling, and it is also necessary to build a refueling station with a larger investment than gasoline and diesel gas stations, which is more difficult to refuel in areas where there is a shortage of refueling stations.

This is like a child drinking milk powder and eating breast milk?

It can only be said that each has its own merits, but it depends on the situation. The first is: after the gasoline car is changed to a gasoline and natural gas dual-fuel vehicle, burning natural gas is naturally cheaper, more than 3 yuan per cubic meter of natural gas, and the heat burned is equivalent to a liter of gasoline, that is, the ** that burns natural gas is basically half of gasoline!

So you can save a year on changing your car. It also depends on the power: because the natural gas is transported from the intake pipe of the engine, the amount of air intake is less, and the air-fuel ratio of the engine is reduced.

Thus the motivation decreases. I also found such an answer in the car gang Q&A, and there are more detailed questions and answers you can get on the car gang Q&A to understand clearly, I hope it will help you.

Under the same vehicle conditions, the oil-burning ones are "stronger" than the steam-burning ones.

If you burn gas, it is more environmentally friendly, and the power of burning oil is sufficient, which is basically the difference, and generally more oil is used.

The gas burning is completely different from the oil burning, the engine structure is also different, and the emission pollution is also different, and the performance is also different.

Gas- and fuel-saving words!

"The cost of burning oil is high and the pollution is high, but the power performance is good. The combustion power is small, but the cost is low. Advantages of "oil-to-gas":

1.The economic benefits are high. Natural gas is easy to be evenly mixed with air in the engine, the combustion is relatively complete, clean, not easy to produce carbon deposits, good anti-explosion performance, will not dilute the lubricating oil, so that the wear of parts in the engine cylinder is greatly reduced, and the life of the engine and the service life of the lubricating oil can be prolonged.

2.Society.

Cars can also burn methanol, in fact, alcohol with a high concentration can also be put into the car, as well as liquefied gas, gas, biofuels, etc., can be used in the engine, and even some solid engines, wood powder and the like, but the overall performance is not as good as gasoline engines.

It is fair to say that cars have many fuels in addition to gasoline, such as hydrogen, electricity, and methanol fuel.

Ethanol fuel, natural gas fuel, just can't use what you say, because he doesn't have such a strong stomach as many.

Water can actually be broken down into other gases that can be used as fuel, but the equipment will be very large and inefficient, critical to the explosive power of combustion.

And the calorific value is not good, and the power is not good. For example, natural gas, such as ethanol, such as methanol, can be, especially methanol, Geely has developed gasoline methanol dual-fuel vehicles, Yuchai.

I developed a methanol engine, and I also have a gasoline methanol dual-fuel cold start.

What about patents. Methanol is a liquid like gasoline, which is convenient for transportation and storage, and the most important thing is that China has a lot of coal, coal to methanol, methanol is cheap, and it saves nearly 50% more money than gasolineSaving money is king.

Second, the production and manufacturing process should be simple, third, it should be easy to preserve and transport, fourth, it is flammable and fast and explosive energy, fifth, it is a gas or liquid state, sixth, the final product of combustion has no harmful substances, and seventh, it is convenient and fast to use.

<> gasoline burns in the engine when the explosive force is strong and relatively stable, less flammable residue, diesel is lower than gasoline ignition point, diesel engine power is strong, but the throttle is loose, the oil in the engine has not been burned, the car with natural gas on the road is still very normal, once the low-grade uphill power is insufficient. In fact, now people widely know, car fuel or gasoline and diesel, the understanding of gasoline is more extensive, because gasoline is particularly dangerous, very flammable, so this is also in the development of our car gasoline, as one of the main fuels of the engine water can not be used as fuel, so it can not provide energy. Unless solar power is used, electrolysis of water.

If you can use the hydrogen produced as fuel, why not use solar power to make an electric car?

There is also diesel, basically the car can only burn these two oils, because diesel will condense at low temperatures, so family cars basically choose to use gasoline, and very few have diesel versions.

You can also use diesel or vegetable oil, which was used in early cars, but over time, gasoline was found to be more efficient, so it was eliminated.

The difference between a gas-burning car and an oil-burning car is as follows:1. Different fuels: The fuel used in fuel vehicles is gasoline, and the fuel used in gas vehicles is natural gas.

2. The ignition point is different: the ignition point of gasoline is 427 degrees, and the ignition point of natural gas is 650 degrees.

3. The fuel reserve method is different: the fuel reserve is in the iron rubberized fuel tank, and the natural gas reserve is in the high-pressure cylinder.

4. The economy is different: burning gas is cheaper than burning oil, about half (depending on the specific situation), but the power of burning gas is not as good as burning oil, because the engine of the general car is designed for burning oil, and burning gas will obviously feel that the horsepower is insufficient.

The difference between burning oil and gas in automobiles is: different fuels, different safety, and different fuel storage methods.

First, the fuel is different.

1. Fuel vehicles: The fuel used is gasoline.

2. Gas vehicles: The fuel used is natural gas.

Second, security is different.

1. Fuel vehicles: the spontaneous ignition point of gasoline is 427 degrees.

2. Gas vehicles: the spontaneous ignition point of natural gas is 650 degrees.

Third, the fuel reserve method is different.

1. Fuel vehicles: The fuel reserve is in the iron rubberized fuel tank.

2. Gas vehicles: natural gas is stored in high-pressure cylinders.

I think it's cheap, but I personally feel that the horsepower is not very sufficient, to put it bluntly, the car is boring to run, not as strong as the gasoline car. If it is a car, it may not be so obvious, if it is a box truck like Wuling Rongguang, after loading the goods, the feeling is particularly obvious. My personal feelings, the sleepiness is just for reference.

The economy of burning gas is good, burning gas is cheaper than burning oil, about half (depending on the specific situation), but the power of burning gas is not as good as burning oil, because the engine of the general car is designed for burning oil, burning gas will obviously feel that the horsepower is insufficient, burning gas is not polluted, and burning oil is polluted.

The biggest difference is to save money, secondly, you can't feel the power of the car with gas, and then it has a certain impact on the service life of the engine.

There is no essential difference!

The only difference is that the fuel is not the same.

When the gas is burned, the exhaust gas emission is almost zero

Save a little money compared to gas oil.

But the power of the car drops a lot!
