Methane gas is the main one. Assuming we understand his pure methane, click to see the details so if the full combustion of methane is released from water and carbon dioxide.
Water pollution, the greenhouse gas carbon dioxide is stationary, and according to the reflection equation, carbon dioxide emissions are still large.
However, nitrogen oxides, hydrocarbons, etc., have a significant environmental effect, but they still emit greenhouse gases, so basically they can only reduce pollution, not completely. Click to see the details of methane although this thing, he is a greenhouse gas, and also destroys the ozone layer, and if he leaks out, he far exceeds the extent of damage, such as carbon dioxide and freon.
China, but now considered a natural product more than it, try to constantly adapt, click to see details currently believes that the cleanest energy source is hydrogen, as long as the hydrogen storage technology is sufficient, he is not dangerous, although there is a way to produce large amounts of hydrogen, then he is the future of hydrogen combustion energy, only water, released after pollution, and electrolysis of water, or other means can also obtain light.

I promise that you will be satisfied, I am using this software now, I know the function of this software very well, as long as you add the bus route, you can find the function, where to go now, what is the next stop, and how long will the bus arrive at your station, just click on it, you can see anything, and you don't have to worry about finding the bus when you go out in the future.

Summary. Natural gas buses, like other vehicles, need to be warmed up before starting, but the warm-up time may vary slightly. Because natural gas fuel needs to be preheated to a certain temperature before it can be ignited, natural gas buses need to be preheated before they start.

I'm sorry I don't understand, but can you elaborate on that?
Generally speaking, natural gas buses need to be heated for 20 30 minutes when the air temperature is lower than 10 degrees Celsius to make the temperature in the car reach the set value and avoid damage caused by the engine temperature being too low. If the temperature is very cold, the warm-up time may be longer. In general, the Tianhe Yuanranqi bus needs to be hot, but the specific time and method may vary, depending on the actual situation.
Generally speaking, there are detailed operating steps and instructions in the car's instruction manual, and the driver of the vehicle will also receive relevant training and guidance. Therefore, you can read the instruction manual carefully when using a natural gas bus to understand the collapse and precautions of the hot car.
That is, the pressure of natural gas transported by the external trunk pipeline is very high, about dozens of kilograms, and the natural gas pressure used at home needs to be relatively low, about 3kpa, so an intermediate device is needed to adjust the natural gas pressure of the pipeline for civil use. These devices are placed in the house and are called pressure regulating stations.
Compressed natural gas (25MPa) is about 1 250 of the volume of natural gas of the same mass in the standard state.
Liquefied natural gas.

Oil and natural gas are formed by organisms in the earth's crust, and the corpses of these organisms go through various reactions to produce some oil, which forms natural gas or oil.
It is cheap to cook with natural gas, and electricity is a tiered electricity price, that is, for example, the electricity you are using now is the first tier, five cents per kilowatt-hour, and there are only five first-tier electricity per year, and when these five are used up, it will become the second-tier electricity price, and each kilowatt-hour of electricity will be much more expensive, so it is still cheaper to use natural gas.
