Diesel vehicles have more power. Can 1 year save a lot of oil?

Diesel vehicles are more powerful, and 1 year can save more than 2000 yuan in fuel costs. How did it do it?

Diesel engines and gasoline engines have different structures.

What's so good about this diesel car? It can save more than 2000 yuan a year. Why do big trucks consume more fuel and cars consume less?

The first reaction we heard from diesel vehicles was fuel saving, good power and difficult refueling. Why can diesel vehicles save fuel? First of all, it has a lot to do with its engine structure.

Then we know that the power generated by the engine is the mixture of air and oil, which explodes when burning, resulting in this power, but the process of its generation is completely different from that of diesel engines and gasoline engines.

How deep is the accelerator pedal of diesel engine and how much oil is injected?

Well, first of all, let's talk about the throttle. The throttle of diesel engine is really the door to control oil. The deeper you step on it, the more oil you spit out.

The throttle of a gasoline engine controls the throttle.

The throttle of a gasoline engine actually controls the throttle, and the throttle is actually a throttle. The bigger I step on it, the more air I take in and the more oil I spray. That's because of these two different structures, the pumping loss of diesel engine is much smaller than that of gasoline engine.

So, for example, an engine with the same displacement of 2.0 and a diesel engine, even if I don't step on the accelerator, the engine can really inhale two liters of air per cycle, but the amount of oil sprayed is less.

How about this gasoline engine? It indirectly reduces the fuel injection by inhaling less, so this 2.0-liter gasoline engine may only inhale 0.5 liter of air when idling, with a difference of 4 times.

The throttle takes in less air.

Then the inhaled air has little effect. Let me give you an analogy.

It's like a needle cylinder. Block one end of the syringe with your hand. At this time, it takes a lot of effort to pull the piston behind the syringe, just like vacuuming. The longer we pull, the harder it will be, right?

If we take one hand away, it will be convenient to take out the syringe at once.

The pumping loss of diesel vehicles will be much smaller.

So is the engine. It's rare for a gasoline engine to fully open its throttle, but we don't often do it, do we? Then usually less air will be inhaled.

That's extra effort. It takes effort to pull it out with the piston in this engine, that is, with the syringe just now.

This effort, which could have driven the car back and forth, was wasted in the process of pulling the needle cylinder. This thing is called pumping loss, and the problem of diesel vehicles will be much smaller.

The compression ratio of diesel engine is very high.

Then I finished the throttle and talked about this compression ratio. Our friends who use gasoline cars basically understand that the higher the compression ratio, the better the power, the more fuel-saving, and the more energy released by each explosion, right?

The compression ratio of that car 10: 1 is not bad, and the more powerful 13: 1, 14: 1 is very powerful?

What about diesel cars? It is 20: 1 or even higher. The harder you compress it, it's like a punch before we fight. The farther back this punch is, the greater the power to hit the front. Almost.

High compression ratio and high energy bring higher working efficiency.

So why can the efficiency of diesel engines be higher? It's because the gasoline engine doesn't work well.

As for gasoline engines, high compression ratio is easy to explode, while diesel engines are unlikely to have this problem because of their own structure, so the compression ratio is high.

For example, this gasoline engine is like firecrackers. We need to light it with a lighter first. It will burn on the fuse for a while, and it will explode if you throw it into the air. It's perfect, beautiful and loud.

Your fuse is short, and it explodes in your hand in advance, hurting your hand and wasting energy. This is called an impact explosion. If you throw it out and fry it on the ground, it will also cause the problem of wrong timing.

Diesel engine has high compression ratio and will not explode.

But diesel engine, it won't have this problem, it doesn't have this fuse, it is a cannon. Throw it out and hit the ground. When it hits, it starts to explode.

Then this time not only there is no explosion, but also the compression ratio can be made better. Moreover, in the process of burning this fuse, it is actually a waste of energy and opportunity, and the diesel engine using cannons will not produce such waste.

Therefore, in general, diesel engines waste less energy in the near future, with higher efficiency, so they are more fuel-efficient, which is determined by their mechanical structure.

How much oil can a car with a diesel engine save in a year?

The fuel consumption of diesel vehicles per 100 kilometers is 27% lower than that of gasoline vehicles.

So how much money can you save? If this diesel car is sold in Europe, the fuel consumption per 100 kilometers is basically about 27% lower than that of the gasoline version with the same displacement.

Diesel cars can save more than 2000 yuan a year.

That hair is that we drive 15000 kilometers a year, and the naturally aspirated car is about 65438+ 10,000 yuan. If you refuel seven kilometers on average, it will be 1050 liters of gasoline and diesel in a year, just 766.5 liters.

Plus the price is different. No.92 gasoline 6. 17, No.95 gasoline 6.56, No.0 diesel 5.77.

This year, diesel vehicles can save 2056 yuan compared with No.92 gasoline vehicles and 2465 yuan compared with No.95 gasoline vehicles. The money saved is enough for several minor maintenance, which is quite cost-effective.

Therefore, the more gas-guzzling a car is, the more likely it is to choose diesel. You see fewer and fewer trucks using gasoline, right?

Although more urea is needed, it costs little.

Some serious friends may say that you think diesel vehicles need diesel and urea, but there is a certain ratio between urea and diesel, generally between 100:3 and 100:5.

In other words, 100 liter of diesel consumes 3-50 liters of urea. What about urea? A liter is about a few dollars, and driving thousands of kilometers is tens of dollars, which is basically negligible. It's ten dollars and twenty dollars to park a car now, right?

Having said so much today, it can be said that from the design principle, diesel vehicles are more efficient, stronger and more fuel-efficient than gasoline vehicles.
