Iron content in gasoline inevitably leads to various engine problems. This element may be present in fuel as a result of the use of iron-containing additives.

Accumulating on the surface of parts such as pistons, valves, rings and cylinders, iron leads to wear and damage, increased fuel consumption and, in some cases, engine damage. Excess iron in gasoline can also lead to the formation of conductive coatings on spark plugs, which makes it difficult to start the engine and leads to its malfunction. In addition, the presence of iron in the fuel can affect the amount of harmful emissions, such as oxides of nitrogen and carbon, which leads to environmental pollution.

Conclusion: high content of iron additives (and additives containing lead and manganese compounds) in gasoline not only negatively affects engine performance, but also has a negative impact on the environment. Therefore, it is important to use only high-quality gasoline to ensure long and reliable engine operation.

What is fractional analysis?

Fractional composition is the main indicator of fuel volatility.

The combustion rate of diesel fuel directly depends on the content of light fractions in it - the lower the start temperature of boiling and distillation at 10% vol., the faster the fuel burns. However, there is a downside - with a high content of light fractions, the viscosity of diesel fuel is reduced, which entails more severe engine operation. Low boiling points at 50% vol. distillation of diesel fuel characterize easier starting of the engine.

If the values obtained during the distillation of diesel fuel are outside the limits at the boil-off control point at 95% vol., this indicates the content of heavy fractions in the fuel, which have a negative effect on mixture formation and, as consequently, on the completeness of fuel combustion.

The volatility of gasoline is associated with such engine characteristics as starting at low temperatures, the probability of formation of vapor locks, vehicle acceleration, engine warm-up rate, as well as wear of the cylinder-piston group and fuel consumption.

The characteristic of gasoline for cold start is usually associated with the volume fraction (%) of gasoline distilled at 70 ° C. The rate of engine warm-up and the throttle response of the car when driving are affected by the volatility of medium fractions, denoted by the distillation control point at 100°C.

Heavy fractions in gasoline, as a rule, are limited due to the possibility of their incomplete evaporation and getting into the engine in liquid state. In this case, the fuel that has entered the cylinders washes away the oil film, which leads to increased engine wear, thinning and increased oil consumption, increased fuel consumption.

In the course of determining the fractional composition, petroleum products are separated into fractions in accordance with their boiling range. Thus, based on the values obtained during distillation, both the chemical composition and its influence on some characteristics that affect the operation of the engine can be predicted.

The fractional composition is determined in the laboratory and is an important tool for the oil industry, as how it allows you to determine the optimal conditions for the production of various petroleum products in accordance with their chemical and physical properties.

Why is it important to use quality automotive fuel?

The reasons why it is important to use quality fuel:

1. Engine performance. High-quality fuel contains fewer impurities and has a higher octane rating, resulting in better engine performance, smoother acceleration and reduced fuel consumption.
2. Engine durability. Due to low-quality fuel, contaminants accumulate in the engine, which lead to its wear, and the risk of breakdown is significantly increased.
3. Compliance with environmental standards. When using high-quality fuel, emissions of harmful substances into the atmosphere are reduced, such as as nitric oxide, hydrocarbons and carbon dioxide, and therefore environmental standards are met.
4. Reliability of work. High-quality fuel helps to avoid problems with ignition, combustion and the formation of soot in the engine, which inevitably leads to a decrease in power and breakdowns.

The use of high-quality fuel helps to ensure reliable engine operation, reduce repair costs, increase productivity and reduce harmful emissions, which is beneficial for both the budget of a private car owner or business, and the health of the environment.

How to check the quality of automotive fuel?

The quality of automotive fuel can be checked using the following methods:

• 👀 Visual inspection. We pay attention, first of all, to the color and transparency of the fuel. Gasoline should be light yellow or colorless, and diesel fuel - light yellow or greenish. The fuel must be transparent, without mechanical impurities or water (stratified drops, turbidity). Of course, the definition of quality "by eye" is not enough.

• 🧪 Using rapid tests. There are special strips of cardboard onto which polymer composite material is applied that changes color when interacting with metals. The principle of their operation is that if you touch such a strip with a filling nozzle, its color will change depending on the content of certain substances in the fuel. Intensity of staining can indicate an excess of sulfur, nitrogen-containing compounds, the presence of lead or iron. But the use of rapid tests allows assessing the quality of gasoline or diesel rather superficially and the result of the study will not have legal force, to say nothing of the sensitivity of the test that might fail.

• 🚘 Using sensors. A special sensor that can be installed on the car's fuel system can measure certain parameters fuels such as density, viscosity, water content and others. The principle of its operation is based on various refractive index of the fuel depending on its quality. However, installing such a sensor will require to prepare the fuel system and involve certain manipulations with it. Moreover, the sensor itself must be subject to periodic maintenance, so that its indicators remain reliable.

• 🔬 Fuel analysis in the lab ⚗️. The most reliable method, which involves a comprehensive study of the fuel for its quality. It allows you to get accurate data without prior intervention in the fuel system and before purchasing a significant amount of petroleum products. At the same time, the study of the fractional composition, the content of water, methanol, sulfates and other substances in the fuel is carried out. Thanks to the conclusions issued by the laboratory, it is possible to compare samples from different suppliers.

It is recommended to use fuel only from reliable suppliers, keep it in stock and, if necessary, carry out quality checks in the laboratory. This will ensure efficient and safe operation of the car, eliminate the risk of buying low-quality petroleum products saving you from the financial costs associated with equipment repair.

There are several types of diesel fuel that differ in their properties and characteristics:

High iron content in gasoline inevitably leads to various engine problems.

1. Class "A" diesel fuel is the highest quality fuel, which is characterized by a high cetane number (more than 50 units) and low sulfur content (up to 0.005%). It is used in modern high-tech diesel engines, operated using high quality fuel and equipped with emission neutralization systems.
2. Class "B" diesel fuel is a medium quality fuel with a cetane number ranging from 45 to 50 units, allowing sulfur content up to 0.2%. Used in older diesel engines that are not equipped with emission control systems.

   Each type of diesel fuel has its advantages and disadvantages, and the choice of a particular type depends on the requirements of the vehicle manufacturer, climatic conditions and other factors.

3. Winter Diesel is a fuel that is designed for use in winter. Contains additives that prevent the formation of paraffin in the fuel at low temperatures.
4. Biodiesel is a fuel that is produced from vegetable oils or animal fats. Considered environmentally friendly, as opposed to traditional diesel fuel. Can be used in conventional diesel engines without additional modifications.
