When the car is running normally, we end up not even noticing if it has a problem. However, we only notice this when symptoms appear that indicate that the car is failing. There are some factors that imply in the failure of the motor of the automobile, being of extreme importance perceive them and verify what is really happening.
Power and power failures in general are the major sources of problems that will cause the vehicle to fail.
Among the various causes of a car failing, the electrical part is one of the largest. When you realize that the car is not going as it should, it is best to be aware of the symptoms to get an idea of what is happening. In this case the electrical part, candle cables, spark plugs and coils, for example, may simply fail or stop working, generating changes in the operation of the propellant.
When you see a car failing, one of the first things many people do is imagine that the sails are worn out. Yes, you need to check the condition of the spark plugs , since the carbonization may arise from a very rich air-fuel mixture and change the operation of the spark plugs . This may cause the spark not to have the same intensity in front of a thick layer of accumulated material. Then you should remove the candles and check their condition, usually replacing them with new ones. Automotive manuals indicate the exchange time between periodic reviews.
Another component that can make the car fail is the candle feeder, the cables that come from the coils. Covered in protective material, the sail cables can be damaged, especially mechanical ones. The test measures the current that is sent to the spark plugs. If there is any change, it will be necessary to change the set. The candle cables, as well as the spark plugs themselves, have varying prices. However, another important component can be damaged by spark plugs and cables in poor condition. This is the coil , which is currently electronic and converts the 12V battery charge up to 45,000V so there are sparks in the combustion chamber.
Failure in the coil is usually due to faults in the candles and cables, which ends up forcing this component. Car failing with gear engaged and bumps when at high speed are some of the symptoms of problems in the coil, which also raises consumption. Prices and services vary by brand and model.
Other than the electrical part, other things can end up in a failing car. Food is one of them. Several problems are associated with fuels and their engine injection devices. These are defects and problems that can be easily solved in specialized workshops. Fuel, electronic fuel injection, fuel filter, fuel pump and injector nozzles may present defects and compromise the operation of the propellant.
Of these, the first is the one that attacks most modern vehicles today, the result of the dishonesty of many owners of stations, who want to earn more. Therefore, they adulterate the fuel . Gasoline with water, kerosene or with a high percentage of ethanol, in this case affecting gasoline-powered cars, may simply contribute to a failing car. The low quality of the product is below the minimum set by the electronic injection system and as a result, it generates a poor burn.
In addition to knocking down the car’s performance, also generating faults, a bad fuel – which can also be ethanol mixed with other substances or even diesel – will affect the electronic injection , especially the so-called “TBI” which is the intake throttle body that can being dirty or faulty. Depending on the make / model, the propeller does not even work as a form of protection.
Another element that may generate malfunction is the fuel filter , affected by impurities present in the product that has been fueled over time in the vehicle. Thus, with the dirty element, the fuel pressure for the injection will be lower and may cause malfunctions, especially at low engine speeds. If it is clogged, it will not start. The nozzles are also affected by dirt or electrical failures. They spray the fuel into the inlet manifold so that the air-fuel mixture can enter with volume inside the combustion chamber and detonate.
However, the decrease in the injected fuel flow by only a little, around 10%, can generate ignitions and engine running. The failing car will have erratic performance, increased fuel consumption and emission, and may even simply stop working, even while driving. The fuel pump is another component that contributes to a failing vehicle on the streets. Dirt in the internal sieve or even electric failure can cause the vehicle to have problems.
At high speeds, the car can choke. On the downside, besides working irregularly, he is also likely to die easily. Lack of strength in the climbs, that pushing effect without accelerating and even failure to start, are symptoms of a problem pump. Therefore, when you notice any of the symptoms described above, seek a specialist workshop to check all components that may be malfunctioning.
