How to identify diesel, how to distinguish diesel from gasoline?

Diesel testing can consult Guangzhou Institute of Machinery Science ****, over the years, we have a reasonable and good service has won the appreciation of our customers, the company has "machinery industry oil inspection and evaluation center", "equipment lubrication and wear status monitoring center", "equipment lubrication management consulting center" three professional institutions, has maintained a long-term cooperative relationship with a number of enterprises, the service is assured and thoughtful, want to know more about the relevant information, welcome to call for consultation.

One. Looking at the color, the national standard diesel is golden in color, clear and transparent without impurities, and the non-standard diesel is generally brown and turbid. Two.

Smelling the smell, the national standard diesel has a normal diesel smell and is not pungent, while the non-standard diesel generally has a strong smell. Three. Depending on how much foam there is, put the oil into the bottle and shake it, the national standard diesel will only produce a little foam, and the non-standard diesel will produce a lot of foam after shaking.

1. Gasoline is pungent and diesel has a light taste.

2. Gasoline is thinnerDiesel is stronger.

3. Their colors are different, gasoline is light, diesel is dark.

4. Gasoline is highly volatile, while diesel is difficult to volatile.

1. Gasoline is very volatile, the smell is very pungent, you can smell it from a distance, the oil color is very clear, while diesel is less volatile and has a faint smell, 2. The color of diesel is darker.

Gasoline and diesel. 3. You can take a small amount of gasoline and diesel, (pay attention to safety) let them burn, the gasoline burning point is low, one point is on, and the combustion is violent, on the contrary, the diesel combustion point is very high, not easy to ignite, and the combustion is also very slow!

1. Look at the evaporation rate. If you put oil on your hands, it will evaporate on its own after a while, and it is difficult for diesel to smoke on its own.

2. The color of the oil. Gasoline is generally colorless and transparent (aircraft gasoline has a blue tinge, low-quality gasoline has a slight yellowish color), diesel has a yellow color similar to cooking oil (much heavier than low-quality gasoline), and heavy diesel oil is black.

3. Gasoline is very easy to burn, almost smokeless when burning, and diesel is more difficult, slow to burn, and has a strong smoke color.

4. Gasoline has low viscosity and good fluidity, while diesel has high viscosity and poor fluidity (especially for heavy diesel).

1. Gasoline is pungent and diesel has a light taste.

2. Gasoline is thinner and diesel is stronger.

3. Gasoline is light and diesel is dark.

The ignition method is different on the vehicle, gasoline is ignited by spark plugs, and diesel is compression-ignited. Diesel fuel is less resistant to knockout. Diesel has less horsepower than gasoline, is heavily polluting, and emits black smoke, but ** is lower.

Contains energyGasoline will be lighter than diesel, and the hydrocarbon compound molecules of diesel contain more carbon atoms than gasoline, and the more carbon atoms, the greater the energy released, so diesel will release more energy than gasoline when it is fully combusted. That's why larger cars are increasingly powered by diesel.

Mixing with air:Gasoline has volatile properties and can easily enter the air, so it mixes well with air, and gasoline can burn more fully after mixing with air. Diesel is not easy to mix with air, and because of this, diesel is easy to appear when the engine is burning, and black smoke is emitted due to insufficient combustion.

Precautions for diesel vehicles.

Do not press the gas pedal when starting the diesel car, and at the same time do not start too fast and the speed is not too high. When the engine runs at high speed for a long time, do not shut down immediately, continue to run at idle speed for about 2 minutes, and then shut down after the temperature is lowered to avoid heat accumulation.

The power of the diesel engine is very good, and it is also very fuel-efficient, the diesel engine of the same displacement is much more powerful than the gasoline engine, and the fuel consumption is also very low. However, a diesel engine should never be refueled after it has run out of diesel, as the engine will run idle and draw in air, which will cause serious damage to the engine.

The smell of gasoline is pungent. The smell of diesel is strong, but it is depressing. In terms of color, gasoline is more like water, and thinner than diesel. Diesel is a bit viscous.

The taste is obviously different, and once you smell it, you can easily tell it.

The color diesel is much darker, a little saucey, and the gasoline is a very pale yellow. It should be mentioned here that the diesel fuel used by the army is also very light, similar to gasoline, which is not easy to have carbon deposits, and the engine exhaust is obviously more snorting than the use of ordinary diesel.

1. Gasoline is pungent and diesel has a light taste.

2. Gasoline is thinnerDiesel is stronger.

3. Their colors are different, gasoline is light, diesel is dark.

4. Gasoline is highly volatile, while diesel is difficult to volatile.

When <> distinguish the quality of diesel, the color of diesel can be observed, and the better diesel color is mostly light yellow or yellow, and the texture is relatively clear. Diesel with poor quality is mostly black or uncurved sail color, and the texture is cloudy. Good quality diesel has a greasy or pungent smell, while poor quality Sohao Banquet diesel is prone to foul smell.
