How to Solve Problems Using Biodiesel on Common Rail? – Energy problems are human problems in general. This is no exception whether you use a vehicle or not. Especially those who use vehicles in every activity, of course, you should be more concerned. This is what gives rise to efforts to make new breakthroughs in replacing fossil fuels.

But replacing fossil fuels is not an easy matter. An example is a biodiesel. This is easy for us to make. Even at home, we can make our own biodiesel. However, in addition to these conveniences, there are problems that occur. In some cases, it turns out that biodiesel causes problems in diesel engines. We will try to discuss it in this article.

How to Solve Problems Using Biodiesel on Common Rail?

If your car is stuck drinking biodiesel, I suggest changing the fuel filter frequently. The use of biodiesel fuel is often done by car owners.

“The fuel filter is the main filter for dirt particles from the fuel in the engine’s fuel line system,” said an expert.

Ideally, we change the fuel filter every 10,000 km. If we count in months, then the distance is equal to 6 months. Or at least we replace the filter together with regular service. A maximum of 5,000 km or 3 months have to change the fuel filter.

According to him, biodiesel contains quite a lot of sulfur particles which make the filter dirty quickly. In addition, there is a vegetable element FAME contained which facilitates the occurrence of clots that trigger blockages.

What exactly is Biodiesel? – Solve Problems Using Biodiesel on Common Rail

Biodiesel is an alternative fuel derived from natural materials such as vegetable and animal oils. This fuel is a methyl ester compound resulting from the esterification or transesterification process of vegetable oils or animal fats. Because its physical properties are the same as diesel oil, biodiesel can be a substitute fuel, especially for diesel-engined vehicles.

In this fuel, there is no petroleum fuel content. However, it can still be mixed according to a certain ratio. The advantage of the existence of biodiesel is that it is easy to use and most importantly can be decomposed naturally without causing harmful toxins.

With combustion products that do not cause harmful toxins, the presence of biodiesel is one solution to overcome the greenhouse effect. Now various countries are trying to use biodiesel. Of course, on the other hand, the government is also seriously directing the public to use electric or hybrid vehicles.

Benefits of biodiesel

Biodiesel has the main benefit of replacing the role of non-renewable fossil energy. Burning these conventional fuels leaves more greenhouse gas emissions. And it destroys the ozone layer on earth. As a result, global warming occurs which threatens habitats on earth. In addition, biodiesel also has many other benefits as follows;

  1. Biodiesel is a fuel made from plants so carbon dioxide gas is as high as fossil fuels.
  2. If you are bothered by the unpleasant smell of burning fossil fuels, this biodiesel combustion does not produce black acid so the aroma of the combustion results is more like the smell of used oil from frying food.
  3. Biodiesel is also a solution for utilizing waste and household waste.
  4. For diesel engines, biodiesel combustion is more complete than diesel fuel so that the engine is better maintained.

Can you make your own biodiesel at home?

As I said earlier, biodiesel is a fuel made from vegetable oil or animal livestock. We can get it from the esterification or transesterification reactions of fatty acids as well as trigleria. Therefore, this environmentally friendly fuel can be renewed by making it. In fact, we can make it ourselves at home.

The raw material for biodiesel can be palm oil. It can also be from oil from nuts such as peanut oil or soybean oil and castor oil. Of all these vegetable ingredients, oil from palm oil is more important. This is because considering that the infrastructure and superstructure already exist in almost all countries.

In addition, the quality of biodiesel from palm oil is much better than that of castor oil and peanut oil. In addition to good quality and definitely more environmentally friendly. Biodiesel from palm oil to make it is also not difficult. In fact, everyone can make their own. Generally, biodiesel synthesis from fatty acid esters has a carbon chain between C6-C22. Meanwhile, palm oil is a type of fatty acid with a carbon chain of C14-C20 so it has the potential to be a raw material for biodiesel.

Biodiesel Making Process

The way biodiesel works are through a two-stage transesterification process. Next, it is necessary to carry out washing, drying, and filtration in the last round.

However, if the raw material comes from CPO, it is better to go through the esterification stage first. The transesterification process consists of two stages. In the first step, mix Potassium Hydroxide (KOH) and methanol (CH30H) with palm oil. The first transesterification reaction takes place for two hours at a temperature of 58-65 degrees C. Fatty acids are the first ingredients that we must put into the reactor. Then we heat it up to a certain temperature.

In this reactor, there is a heater and stirrer. During the heating process, the stirrer continues to run. When it reaches 63 degrees C, we will put the mixture of methanol and KOH into the reactor and start calculating the reaction time. At the end of the reaction, a methyl ester is formed with a conversion rate of about 94%. We then precipitate this product for a certain time to separate the methyl ester and glycerol. This glycerol is in the bottom layer because it is heavier than the methyl ester.

After the transesterification II process is complete, we need to re-precipitate so that the glycerol is separated from the methyl ester completely. Precipitation II is usually shorter than precipitation I. This is because less glycerol is formed and will dissolve after the washing process. This process aims to precipitate and remove unnecessary compounds such as residual glycerol and methanol. We do this washing at a temperature of about 55 degrees C three times until the pH of the mixture becomes normal (pH 6.8-7.2).

The next process is drying. Drying aims to remove the water mixed in the methyl ester. This process takes 10 minutes with a temperature of 130 degrees C. In the final stage, there is a process of making biodiesel which is filtration with the aim of removing biodiesel impurity particles formed during the process. Usually, these particles are in the form of rust originating from the reactor walls, pipe walls, or dirt from raw materials.
