What happens to a car with bad gas? Will there be stuffiness?

If the car is filled with bad oil, it may cause a series of problems such as difficulty in starting, or even failure to start, bad exhaust smell, inability to accelerate, and high fuel consumption. If the car is difficult to start, cannot start, the engine shakes, cannot accelerate, shifts the shock, and the vehicle with valve sound should stop immediately and apply to the 4S shop for rescue.

If the cylinder pressure is normal, disassemble the cylinder head for cleaning, completely empty the residual oil in the fuel tank, replenish high-quality gasoline, clean the throttle, clean the nozzle, clean the combustion chamber, replace the gasoline grille and gasoline pump. Poor exhaust emissions (or odor elimination) from gasoline combustion due to substandard oil can be hazardous to three-way catalytic converters and oxygen sensors. Many people may ignore this part, but if it is damaged to a certain extent and there is no maintenance, it needs to be replaced, and it is a very casual thing to spend thousands of dollars to replace.

When refueling daily, you should learn to discern the quality of the oil. The color can be seen, standard gasoline is colorless, transparent or golden yellow, and low-quality gasoline is turbid, dull, and contains suspended impurities; The second is the smell, bad oil used to have a pungent smell, while good oil did not. If you add low-quality gasoline to a car, the car's power will decrease, the driving range will decrease, and the carbon deposits in the engine will increase.

Using low-quality gasoline can lead to poor driving performance and even traffic accidents. If the quality of the gasoline is poor, the most obvious phenomenon is the carbon build-up in the engine, which may not be visible from the outside. If you regularly use low-quality gasoline and inspect the inside of the engine with an endoscope, there will be a lot of black carbon deposited inside the engine.

Poorly processed gasoline needs to drain the residual oil in the empty tank, refill the high-quality gasoline, clean the nozzles, clean the combustion chamber, and replace the tank. The driving is normal, but the engine is slightly idling. Drain the tank thoroughly, empty the empty tank, replenish high-quality gasoline, clean the throttle and nozzles, clean the combustion chamber, replace the gasoline rack and oil pump.

If the car is added with bad gasoline, the impact on the car is very large, because gasoline is actually the heart of the car, if the oil quality is not good, then the car will be poisoned, which will cause damage to the engine; There will be stuffiness, and it will also damage the engine and cause the car to break down, so it is very bad for the car.

There will be problems with the engine, there is no way to provide good kinetic energy, the car is very weak, and there will be a stuffy situation.

There will be stuffiness, and it will feel abnormal during driving, and the taste is not particularly good.

Summary. Hello, I am your exclusive technician, attentive, careful, and dedicated to answering your car questions, and finding corresponding problem solutions and solutions for you!

Based on your question, the following analysis was conducted.

The analysis scheme is as follows:

If your car has a bad gasoline and the car power is not good, this suggestion is that you directly put this origin, if you have half of the good gasoline, this is also not good, because there may be water in the bad oil, so if you add good gasoline to dilute it, you still can't get rid of this water.

I hope my answer will be helpful to you.

My car has bad gas, the car has an effect, and then I add half of the good gas, will it be alleviated?

Dear, this question is up to me, it takes a little time to type, please be patient, thank you!

Solution: In this case, it is best to put all the oil out and refill it again.

I hope my answer will be helpful to you.

The car has been added with inferior oil, and now the belt speed is unstable, how should it be solved?

This can change all the oil and then clean the oil circuit.

Do you go to a 4S shop for cleaning?

Just go to a regular repair shop for repairs.

Summary. Hello, a car with low-quality oil has the following symptoms: it is difficult to start, or even cannot start; Idle engine shakes after starting; Significant vibrations in the body; The smell of the exhaust gas is unpleasant; The valve sounds; Weak acceleration and high fuel consumption; There is a shock to the shifting.

Hello Orange, a car with low-quality oil has the following symptoms: it is difficult to start, or even cannot start; Idle engine shakes after starting; Significant vibrations in the body; The smell of the gas discharged from the attack group is unpleasant; The valve sounds; Weak acceleration and high fuel consumption; There is an eyeing impact in shifting gears.

After adding inferior gasoline, the vehicle maintenance plan is as follows: 1. At present, it can drive normally and there are no symptoms, the remaining oil in the fuel tank should be completely emptied, and the high-quality gasoline should be re-added, the paint nozzle should be cleaned, the combustion chamber should be cleaned, and the gasoline grid should be replaced by a suffocating lead.

2. The driving is normal, but the engine idle speed has a slight shaking, Lao Cha should completely empty the remaining oil in the fuel tank, re-add high-quality gasoline, clean the throttle, clean the paint nozzle, clean the combustion chamber, and replace the gasoline and gasoline pump.

3. Vehicles with difficulty in starting, failure to start, engine shaking, weak acceleration, gear shift impact, and ringing valves should also be stopped immediately and applied for rescue by 4S shop. Measure the cylinder pressure, if the cylinder pressure is normal, disassemble the cylinder cover for cleaning, completely empty the remaining oil in the fuel tank, re-add high-quality gasoline, clean the throttle gate, clean the spare paint nozzle, clean the combustion chamber, and replace the gasoline grid and gasoline pump.

The car accelerates sharply uphill, and the engine has a clattering sound.

It's like a valve sound.

The clatter of the engine when accelerating may be caused by the sound of the valves, or it may be caused by the lack of lubrication in the engine valves. There are many models of engines that use in-cylinder direct injection technology, in-cylinder direct injection requires higher injection pressure, and the engine equipped with in-cylinder direct injection jujube technology will have a high-pressure oil pump in the engine compartment, and the high-pressure oil pump will produce a clattering sound when working, which is normal.

1. It does not meet the requirements of the vehicle compression ratio, and the gasoline combustion is not sufficient, which will lead to the aggravation of the detonation of the engine, the decrease in power, the increase in fuel consumption, the increase in carbon deposition of the cylinder and the noveil, etc., if the detonation has been generated, the piston ring will be broken, and the connecting rod will be broken, which will greatly shorten the service life of the engine.

2. It will lead to the poisoning of the oxygen sensor, which will block the exhaust pipe and the three-way catalytic force, resulting in a decrease in engine power. When the engine uses leaded gasoline, the spark plug insulator is generally white powder or yellow.

3. If it leads to deposition in the intake system or the intake valve is bonded, it is generally required that the gasoline is not washed with less than 30mg 100ml before adding detergent. If the gasoline gum is too high, then there will be problems with the air intake system.

The first and very simple truth is that it does not burn well. The car was sluggish, produced a lot of carbon deposits, and it didn't take long for the valves and spark plugs to be prevented from starting the car by carbon deposits.

Second, it depends on how bad the quality of the oil is added.

If the quality is too poor, such as impurities, water, etc., the effect will be immediately apparent: the car will be difficult to start, emit black smoke, fire during driving, and damage the engine.

If the quality is not too bad, the effect is like chronic poisoning, which is easy to produce carbon deposits, acceleration weakness, and increased fuel consumption. Long-term use will not only reduce the performance of the car, but also cause serious damage to the engine!

Third, it is mainly necessary to pay attention to the key indicators of oil products, such as the octane number of gasoline, if the octane number is low, engine knocking may occur, which will shorten the service life of the engine and damage the engine; When the actual gum of gasoline is too high, it will produce gum and carbon deposits during the combustion process, thereby damaging the engine, and in serious cases, the engine of the hot and cold cars will make abnormal noise, idle shaking, serious lack of power, and even the engine can not start. Finally, there is the evaporation and sulfur content of gasoline. The important indicators of diesel fuel are cetane number, kinematic viscosity, flash point, sulfur content, etc.

Bad gasoline. Generally, the new value is high, the car model is low, the new value is good, the ignition point of the car is low, the car may emit black smoke, detonation, and poor acceleration of the car, which will aggravate the wear and tear of the engine.

What kind of bad law are you referring to? It is low octane. Or leaded gasoline. I don't know if you're a car or something else. A low octane number can produce a violent. Lead can make the three-way catalysis ineffective and the oxygen sensor poisoned.

It broke down that day, and the trailer oil washing road accessories man-hours were two or three thousand.

Black smoke should be because you add inferior gasoline to cause damage to the oxygen sensor, the oxygen sensor can not perceive the oxygen content in the exhaust after the damage of the oxygen sensor, so it transmits an error signal to the ECU computer, resulting in the ECU command fuel injection system to increase the amount of fuel injection, due to the excessive amount of fuel injection, the exhaust pipe will emit black smoke, and the engine power will also decrease.

What happens if the gasoline is not good, if the gasoline used is not good, it will cause a loss of power in the car, and the car will have no power; If it is severe, it will knock, pull the cylinder, and eventually the engine will be scrapped. The concept of low-quality gasoline is a bit vague because there are many types of gasoline, and the symptoms of each case will be different. Therefore, it is necessary to distinguish and analyze according to different situations.

Gasoline is not good, and there are several common situations: the first is that there are too many impurities. Too many impurities in gasoline can cause the car's small holes or filter parts to become clogged, resulting in poor oil supply and reduced engine function.

The second is that there is too much moisture. First thing to know: water is heavier than gasoline, and the moisture in gasoline will be deposited at the bottom of the tank.

When the moisture reaches a certain amount, it will first block the oil circuit, causing the vehicle to fail to start. Then, the metal parts of the oil circuit, such as the oil pump bearings, rust, lead to accelerated damage. When the water content is higher than the inlet position of the oil pump, it is transported to the fuel line, sprayed into the intake manifold in a mist through the injector, and then into the cylinder.

In this case, even if the engine is not scrapped, it should be overhauled. The third is leaded gasoline. Leaded gasoline can cause oxygen sensor poisoning, clogged exhaust pipes and three-way catalytic converters, and reduced engine power.

If the gasoline used is not good, the car will be poisoned, the acceleration of the vehicle will be affected by the light air grill, and the engine will be damaged, and it needs to be dismantled and repaired.

The concept of bad gas is a bit vague because bad gas can be divided into many conditions, and the symptoms that come with each condition will be different. Therefore, it is necessary to distinguish the analysis according to different situations. Gasoline is not good, and the common ones are the following:

The first is that it contains too many impurities. Too much gasoline impurities can cause small holes or filtering parts in the car to be blocked, resulting in poor oil supply and reduced engine function.

The second is that it contains too much water. First thing to know: water is heavier than gasoline, and the moisture in gasoline is deposited at the bottom of the tank.

When the moisture reaches a certain amount, it will first block the oil circuit and cause the vehicle to fail to start. Then the key loss of the metal manuscript pin parts of the oil circuit (such as the oil pump bearing) is corroded, and the damage is accelerated. When the moisture is above the inlet of the pump, it is transported to the fuel line, through the injector, sprayed into the intake manifold in a mist and then into the cylinder.

In this case, the engine must be overhauled, if not scrapped.

The third type is leaded gasoline. Gasoline containing lead can poison the oxygen sensor, clog the exhaust pipe and three-way catalytic converter, and cause the engine power to decrease.
