What are the dangers of low quality gasoline to cars?

Inferior gasoline can cause the following hazards to a car:

Reduced engine performance: Low-quality gasoline may contain impurities, sediments, and contaminants that can affect the combustion process and the proper functioning of the fuel injection system. This can lead to degraded engine performance such as lack of power, poor acceleration, and reduced fuel economy.

Engine carbon deposits: Additives and impurities in low-quality gasoline can cause carbon deposits to build up inside the engine, especially on cylinder walls, piston rings, and intake valves. Carbon deposits can affect combustion efficiency, increase engine wear, reduce engine performance and lead to erratic idling and misfire problems.

Problems at high temperatures: Inferior gasoline can evaporate and oxidize at high temperatures, forming sediments and gums. These deposits can clog fuel nozzles, fuel filters, and other parts of the fuel system, leading to low fuel**, incomplete combustion, and engine failure.

Oxygen sensor and catalytic converter failure: Contaminants and additives in low-quality gasoline can damage oxygen sensors and catalytic converters. Oxygen sensors are an important component in controlling fuel mix ratios and emissions, while catalytic converters help reduce emissions of harmful gases.

Poor quality gasoline can cause these components to fail prematurely, increase emissions and may cause vehicles to fail emissions testing.

1.Clog the injectors.

Once unqualified gasoline is added, although there will be no abnormality in a short period of time, with the increase of the use time of inferior gasoline, the most obvious changes in the vehicle are the decrease in power, engine idle shake, and the extension of cold start time. Moreover, the smell of exhaust gases after starting is not the smell of normal gasoline, but a smelly and pungent smell.

But there are too many impurities in low-quality fuel, especially for the injector, the nozzle hole itself is small, once blocked, it will lead to poor oil supply, which may lead to a decrease in engine performance, and even the engine stalls or even fails to start. Not only that, but auto parts such as fuel filters, fuel pumps, and oil pump filters are also prone to clogging.

2.The rate of carbon deposition is accelerating.

Because there are too many impurities in low-quality fuel, which are usually present in gasoline in the form of colloids, they can be deposited in the air intakes, valves and cylinders, even through the filtration unit, causing carbon deposits to form more quickly. Ordinary fuel may only wash the throttle once every 20,000 to 30,000 kilometers, and cars with inferior fuel may wash once every 10,000 kilometers. However, if there is too much carbon deposit, there will be difficulties in cold start, abnormal acceleration, increased fuel consumption, detonation, etc.

3.Resulting in poisoning of the three-way catalytic converter.

As we all know, the three-way catalytic converter is a kind of purification device in the automobile exhaust system, which can redox harmful gases such as CO, HC, and NOX in automobile exhaust into harmless carbon dioxide, water and nitrogen. If there are too many impurities in the fuel, these impurities will adhere to the three-way catalytic converter after combustion.

If the three-way catalytic converter is slightly clogged, the exhaust emissions will not meet the standard. In severe cases, the working temperature of the three-way catalytic converter will increase, the three-way catalytic converter will burn, the power will be seriously reduced, and the flameout will often occur. What's more, the three-way catalytic converter will be directly clogged after adding a low-quality fuel.

Knowing that a one-time replacement of a three-way catalytic converter is enough for you to add a few more tanks of oil.

Inferior gasoline can cause the following hazards to a car:

Reduced engine performance: Inferior gasoline may contain impurities and foreign substances, which can reduce the explosiveness and cleanliness of gasoline, resulting in inadequate engine combustion, accelerated wear and aging.

Oil circuit blockage: The sediment and impurities that may exist in inferior gasoline will accumulate and accumulate in the oil circuit, resulting in oil circuit blockage and affecting the normal operation of the car.

Reduced fuel economy: Inferior gasoline may contain more incomplete combustion products, resulting in a decrease in fuel economy and an increase in fuel consumption.

Inferior gasoline has multiple hazards to automobiles, including but not limited to the following:

1.Reduced oil quality: The chemical composition of inferior gasoline is unstable, which may contain a large number of impurities and excessive acids, which will have a corrosive effect on the internal metal parts of the engine, destroy the lubrication system, lead to premature aging of the engine, and reduce the service life and quality of the oil.

2.Affect engine performance: Incomplete combustion of inferior gasoline, in which low-quality alkanes will lead to an increase in carbon monoxide, nitrogen oxides and other harmful substances in the exhaust gas, and at the same time will increase the amount of carbon deposits in the engine, resulting in engine knocking, power decline, fuel consumption and other problems.

3.Damage to the oil system: Inferior gasoline may contain a large number of suspended particles and impurities, which will clog the oil system, affect the fuel**, and cause the engine to fail to start normally or have difficulty starting.

Inferior gasoline can have a big impact on the performance and longevity of a car. Here are some of the possible hazards:

Deterioration of engine performance: Inferior gasoline may contain more impurities and inadequate combustion substances, which will affect the combustion efficiency of the fuel, reduce the power of the engine, and make the acceleration worse.

Carbon deposition in the combustion chamber: Inferior gasoline may lead to carbon deposition in the combustion chamber, making the automobile engine run unstable, and abnormal phenomena such as shaking and abnormal noise.

Engine failure: If there are too many impurities in low-quality gasoline, these substances may clog the engine's fuel injectors, oil pumps, oil circuits and other components, causing engine failure.

Increased maintenance costs: Poor quality gasoline can lead to various breakdowns in the car that require more frequent maintenance and repairs, which increases the maintenance cost of car owners.

In short, in order to ensure the normal operation of the car and prolong the service life of the car, we should choose the best gasoline as much as possible and follow the manufacturer's instructions for use.

The use of low-quality gasoline can cause the following hazards to the car:

Reduce oil quality: Inferior gasoline has a high content of impurities, which is easy to be deposited in all parts of the engine, reducing the quality of oil.

Polluting the engine: Impurities in inferior gasoline are easy to accumulate in the engine, contaminating the oil circuit, oil pump and fuel injector, resulting in the engine not working properly.

Affect engine performance: The low combustion value in low-quality gasoline may lead to problems such as insufficient engine power, increased fuel consumption, and even flameout.

Damage to the oxidation catalyst: Impurities and additives in low-quality gasoline can damage the oxidation catalyst and affect exhaust emissions.

Delay fault detection: Poor quality gasoline may affect the operation of the engine, causing the vehicle to fail fault detection such as emission detection normally.

If the long-term use of gasoline lower than the required number of the car is equivalent to the use of low-quality gasoline, it can be said to be a car killer. Because it does not meet the requirements of the vehicle compression ratio, the gasoline combustion is not sufficient, which will lead to the aggravation of the engine, the decrease of power, the increase of fuel consumption, the increase of carbon deposition of the cylinder and the noveil, etc., if the knocking has been generated, the piston ring will be broken, the connecting rod will be broken, and the service life of the engine will be greatly shortened.

Poor quality gasoline can lead to insufficient combustion, damage to the vehicle's engine, and environmental impact.

Inferior gasoline is not burned sufficiently, and the resulting carbon deposits clog the fuel injectors, combustion chambers, and air intakes. The harm caused by fuel consumption increases, the power becomes weaker, and the engine shakes greatly. Driving performance and comfort are reduced.

1.There are many impurities in the inferior oil that blocks the oil circuit, which can easily lead to insufficient fuel combustion, resulting in many fuel impurities, making the car oil supply not smooth, and making the car shake seriously when driving. 2.

Some of the carbon deposits produced during the insufficient combustion of gasoline in the engine will adhere to the surface of the engine, which will soon increase the fuel consumption of the car, and the engine will be easily damaged over time. 3.The three-way catalytic converter and the oxygen sensor damage oil product is unqualified and causes the exhaust gas emission produced after gasoline combustion is not smooth, the three-way catalytic converter has the effect of purifying the exhaust gas for discharge, if there are more impurities in the exhaust gas, it will be attached to the three-way catalytic converter, resulting in the damage of the three-way catalytic converter.

The hazards of low-quality gasoline to automobiles include the following:1Block the oil circuit.

Due to the large number of impurities in the inferior oil, it is easy to lead to insufficient fuel combustion, and a large number of fuel impurities are produced, resulting in poor fuel supply and serious shaking of the car. 2.Activate the spine of this key machine to deposit carbon.

In the process of insufficient combustion, some carbon deposits will be generated, which will adhere to the surface of the engine, increase the fuel consumption of the car, and the accumulation over a long period of time may also lead to engine damage. 3.The three-way catalytic converter and oxygen sensor are damaged.

The three-way catalytic converter can purify the exhaust gas, but if there are a large number of impurities in the exhaust gas, it will adhere to the three-way catalytic converter, affecting its work efficiency, and then causing damage to the three-way catalytic converter and even the oxygen sensor.
