Is fuel treasure useful or not? For better or worse, let's talk about beaker experiments.

I believe that many car owners have been promoted to refueling treasure when they refuel at gas stations. The salesman is right, but the passengers are always suspicious. After all, it is added to the fuel tank, so we have to be cautious. So what's the role of fuel treasure? With so many kinds of fuel treasure on the market, how should we choose?

Whether it is useful or not, I will introduce it in detail later. Let me talk about the classification of fuel treasure:

Fuel treasure in the market can be roughly divided into three types, namely:

1, maintenance type 2, clean type? 3. Power lifting type

Both maintenance type and cleaning type can clean carbon deposits, and their fundamental difference lies in the different addition amount;

Generally, the curing additive is less than 80ml, which can well inhibit the generation of carbon deposit, and is suitable for new cars, cars without carbon deposit or cars with less carbon deposit.

The cleaning type has a large capacity, about 200-400m, and is suitable for vehicles with 20-30 thousand kilometers. After use, it can effectively remove carbon deposits in the fuel system.

Power fuel treasure mainly means that the power of the engine will be obviously improved after using the product, which is suitable for old cars that have already felt obvious power shortage.

Maintenance and cleaning ingredients can be roughly divided into two categories: peas? And PIBA. PEA can effectively remove carbon deposits in the combustion chamber of internal direct injection engine. PEA (Polyether Amine) is the only added chemical component that can adapt to this high temperature and high pressure environment and does not produce deposits because the in-cylinder direct injection system injects gasoline directly into the combustion chamber. In the traditional fuel treasure, PIBA (polyisobutylene amine) is the main component. This additive can effectively remove carbon deposits on multi-point injection vehicles, but it has poor volatility in the high temperature and high pressure environment (combustion chamber) of direct injection vehicles and will quickly form deposits. Therefore, adding the traditional fuel treasure to the in-cylinder direct injection vehicle can not only clean up the carbon deposit in the combustion chamber, but also seriously increase the accumulation of carbon deposit. So if you choose products in the future, you must choose the ingredients of PIBA.

Next, let's talk about whether fuel treasure is useful or not. I looked up some information on the Internet, and finally decided to do a beaker experiment to test whether fuel treasure can remove carbon deposits.

My experiment today is mainly divided into the following steps.

1. Simulate the combustion chamber environment to make carbon deposit samples.

2. Add the mixed proportion of Fubao gasoline to the prepared carbon deposit sample and clean the carbon deposit.

3. Simulate the combustion chamber environment, heat the mixture to about 300 degrees, and observe the cleaning effect of carbon deposit.

A week before I was going to do it, I bought all the instruments that might be used in the experiment from a website.

Fuel treasure has selected four popular products on the Internet. This time, let's have a test to see how fuel treasure works.

The first one is Chevron gasoline additive in the United States, the main component content is pea, and a bottle of 355ml blended with 50L gasoline;

Second, Japanese HKS gasoline additive, the main component content is peas, a bottle of 225ml blended with 50L gasoline;

The third is the domestic mustard green gasoline additive, the main component content is peas, a bottle of 400ml blended with 50L gasoline;

Next, I started my experiment:

Step 1: simulate the combustion chamber environment and make carbon deposit;

Firstly, take out 20 ml of gasoline from the measuring cylinder, add the gasoline in the measuring cylinder into four beakers respectively, and number the beakers as 1, 2, 3 and 4;

4 gasoline samples were obtained; ?

Next, four carbon deposit samples were heated. I used a lichen heater and adjusted the temperature of the heater to 292 degrees. Test the temperature of each point with a temperature tester to ensure that the temperatures of the four beakers are similar;

Four gasoline samples were heated on a heating furnace;

After about 20 minutes, the gasoline in the four beakers is almost dry, and the smell is very strong. After airing for another half an hour, four carbon deposit samples were finally obtained. ?

Step 2: Add fuel treasure gasoline into the prepared carbon deposit sample according to the mixing ratio, and clean the carbon deposit.

Because it is the first time to do beaker experiment, the carbon deposit sample is not mature enough. Some friends may ask, why do you need to make four carbon deposit samples for testing three products, because there is another one as a control. Next, 50 ml of gasoline was taken out of the measuring cylinder and added to each carbon deposit sample to obtain four kinds of mixed liquids of carbon deposit and gasoline again.

The next step is the most critical step, according to the blending ratio of the three products, adding fuel treasure suitable for proportional capacity;

Pipet into beaker No.2, 355UL Chevron fuel treasure.

First, replace the newly used pipette tip with a new pipette. In order to ensure the accuracy of the experiment, continue to add 225ULHKS fuel treasure to beaker 3;

Suck 400uL of mustard green fuel solution with a pipette, and add No.4 carbon deposit;

Finally, four samples were obtained, and the next step was the most critical step in the experiment.

Simulate the combustion chamber environment, heat the mixture to about 300 degrees, and observe the cleaning effect of carbon deposit.

Adjust the heating furnace to 300 degrees for heating. To avoid drying, check the effect every 10 minute.

After getting four final samples, there is still some gasoline that is not completely burned. When finally observing the effect, the experimental effect will not be affected by pouring waste liquid into it. Finally, let's take a look at the cleaning effect after adding the product. In the beaker without adding any fuel treasure, there is almost no dissolved carbon deposit;

After adding Chevron to No.2, the carbon deposit has a certain removal effect, but there is still some residual carbon deposit.

I'm looking forward to beaker No.3 with HKS, because the official promotion contains 70% peas. The final result is not satisfactory, some carbon deposits have been removed, but the removal is not very thorough;

Finally, the No.4 beaker of mustard green burning treasure really gave me a big surprise. Among the three products, mustard green has the best effect of removing carbon deposits, most of which have been removed and the bottom of the cup is relatively clean.

Seeing the final effect, there are surprises and surprises. The removal effect of the three products is very good, Chevron and HKS are worthy of being big brands, and they are excellent in removing carbon deposits.

But to my surprise, compared with fuel treasure, two foreign network celebrities, mustard green in China has a better effect of removing carbon deposits, and the strength of domestic e-commerce brands should not be underestimated! Seeing this result, I dare to guess, is it because the quality of foreign gasoline is high, so the cleaning effect in fuel treasure is not too high? Domestic products are better because they are developed for domestic oil products and road conditions.

statement

The purpose of this experiment is to simulate the ability of each additive to dissolve carbon deposits at high temperature as much as possible under feasible experimental conditions. Although this experiment is repeatable, it is still far from the bench test. The results are for reference only, and no qualitative conclusions can be given. Please understand.
