Eight symptoms before a car engine failure! As early as possible early prevention!

Today's cars are becoming more and more intelligent. Many vehicles integrate trip computers and can indicate hidden troubles. However, when the trip computer issues a warning, it shows that the fault has been formed. In fact, in addition to trip computer tips, before the failure of the vehicle itself will have some signs, as long as we find in time, do inspections and preventive measures, some repairs can be saved. Let's take a look at common symptoms.

01. Engine abnormality

The engine is equivalent to the "heart" of a car. Just as a person's heart beats quickly and indicates that he is sick, severe engine jitter often indicates a failure. It is recommended that we should not continue to move forward after this kind of shaking failure. Parking is the most reliable way to stop.

Suddenly high idling speed refers to the normal running of the car on the road surface. The sudden stoppage of the engine speed when the parking is suspended in the neutral gear exceeds the usual rotation speed. This problem is mainly caused by the idle speed motor jam or circuit failure. A long time idle speed is too high to easily cause the engine. Open the pot.

02. Pungent odor

The odor here does not mean the pungent smell of a new car. It refers to the charred or gasoline smell. When the car is in operation, if there are brake failures, clutch slips and other faults, it will emit the burnt smell of the friction discs; when the engine overheats and the lubricating oil cylinder burns, it will emit a special odor; the circuit is short-circuited and grounded. When the wire burns, it will also have a burnt smell.

Therefore, smell the odor should immediately get off the inspection, and go to the repair shop in time to find out the reasons to prevent greater losses.

03. Obvious oil leakage

This is actually best observed. Before driving, look for a beach of oil underneath the car chassis. However, it should be noted that when the air conditioner is turned on in summer, there will be drip under the car. This is a normal phenomenon, so you must pay attention to distinguish water stains and oil stains.

In addition to looking at the ground, you should regularly open the hood to see what's going on inside. If there is a lot of oil, it's also an oil spill.

04. Abnormal sound of chassis

In the process of driving, there was a sound in the chassis, mainly due to the three-way catalytic converter and suspension problems. The three-way catalytic converter may not be able to accumulate too much accumulated carbon, it will ring in the three yuan shell Granrand. If it is a matter of suspension, it will be more careful. Severe points may break during driving and the consequences may be disastrous. In this case, stop by the roadside and wait for the 4S shop staff to handle it.

05. Brake abnormal sound

The brake abnormal sound is also more common, the new car running abnormal sound, you can try to step on a few foot brakes, has not been eased, it shows that the fault. If you make a harsh squeak while braking for a long time, this is undoubtedly equal to prompting you to replace the new brake pads.

06. Exhaust pipe abnormal sound

Exhaust pipe abnormal sound may be due to silencer or exhaust pipe damage, or may be part of the sheet metal or bumper off, step on the accelerator pedal, will hear the sound of noise from the exhaust pipe, long-term if not resolved, This will increase fuel consumption. The engine is the heart of the vehicle and it is also a critical part of the vehicle. It is also prone to malfunction.

07. Abnormally high fuel consumption

Generally, the fuel consumption will be relatively stable under good conditions of the automobile. Even with traffic jams, fuel consumption should be maintained within a reasonable range.

If it is found that the car's fuel consumption has risen abnormally over a period of time, attention should be paid to the exclusion of driving factors and road factors. It may be that the engine control system is not working properly, or that component failures in the driving line increase the running resistance, resulting in increased fuel consumption.

08. Startup difficulties are delayed

Whether or not to start the fire when there is a delay compared to the usual start, in fact, this is very good judgment, this time we must also consider the issue of external factors, if the weather is cold, it may be caused by a relatively large battery consumption caused by insufficient battery, but if it is If you have used the battery for more than two years, you can be careful about it. You would prefer to replace the battery in advance or not to call the trailer.

How to solve these engine problems?

Cleaning method

1, 4L / barrel packaging, instead of oil running, safe and efficient, more thorough cleaning (crankcase, oil, oil pan, piston, etc.);

2, special lubrication system cleaning equipment (professional value, simple operation);

3, the full name of the cleaning process visualization (transparent window, filter from white to black, customer experience is good);

4, oil filling port into the oil, the oil pan screw out (operational safety without risk, the cost of special joints is 0);

5, dynamic cycle cleaning, sludge, dirt nowhere to escape (oil sludge, dirt in the continuous cycle is filtered into the machine, to ensure that there is no residue in the engine).

Tips: The old engine should not be cleaned. For engines with driving mileage of more than 200,000 kilometers, wear gap is too large and the burning oil is particularly serious, the lubrication system should be carefully cleaned. Because the special cleaning oil can clean the sludge, carbon deposits, etc., which have been sealed and adhered around the piston ring, the seal performance of the piston and the cylinder wall with the original large gap is reduced, and the failure of the burning oil is aggravated.
