What's wrong with the engine shock sensor?

1. When the engine inhales the fuel steam and air mixture and enters the compression link, the spark plug will automatically explode before ignition, resulting in cylinder vibration, which is the explosion. This phenomenon is particularly common because fuel contains low-flammable substances.

2. It is usually piezoelectric ceramics. When the engine vibrates, the ceramics inside are squeezed to produce electrical signals. Because this electrical signal is very weak, the connection wires of ordinary shock sensors are wrapped with shielded wires. The explosion sensor is an AC signal generator, but it is very different from most other AC signal generators in cars.

3. First of all, the shell and internal parts of the blast sensor are very fragile and are easily affected by factors such as vibration, temperature change and chemical corrosion, resulting in failure. Especially in high temperature, humidity and corrosion environments, the failure rate of the blast sensor will increase greatly. Secondly, the use environment of the car is also related to the life of the shock sensor.

4. The reasons for the engine explosion are as follows: the air-fuel ratio is incorrect. Too thinThe fuel-air mixing ratio will increase the combustion temperature, and the increase in the combustion temperature will cause the engine temperature to rise, which is of course easy to explode; the engine accumulates excessive carbon.

5. Unlike stators and magnetoresistors, they are usually piezoelectric components. They are made of special materials that can sense mechanical pressure or vibration (for example, when the engine starts to explode, it can generate AC voltage). Engine explosions caused by too early fire, poor exhaust gas recycling and poor-quality fuel will cause engine damage.

6. The cause of the failure of the detonation sensor. The phenomenon of the failure of the detonation sensor is that the engine does not have an obvious response, and the fuel consumption increases and the engine shakes slightly: when the engine is working, the ignition time is too early (ignition advance angle), the load, temperature and fuel quality of the engine will cause The motive explodes.

What is the function of the explosion sensor?

It is used to measure engine shake and adjust the ignition advance angle when the engine detonates. It is usually piezoelectric ceramics. When the engine vibrates, the ceramics inside are squeezed to produce electrical signals. Because this electrical signal is very weak, the connection wires of ordinary shock sensors are wrapped with shielded wires.

It is used to measure engine shake and adjust the ignition advance angle when the engine explodes; generally, it is piezoelectric ceramic, and when the engine vibrates, the ceramic inside will be pressed to generate an electrical signal. Because the electrical signal is relatively weak, the connection wire of the general shock sensor is covered by the shielded wire.

Explosive sensor is a piezoelectric sensor that can convert vibration into voltage. The detonation sensor is usually installed on the generator of a car to detect whether the engine may cause detonation, so as to adjust the ignition advance time through the electronic control system to avoid the occurrence of detonation.

What is the function of the engine shock sensor?

1. The explosion sensor is an AC signal generator, butThey are very different from most other automotive AC signal generators. In addition to detecting the speed and position of the hinge like magnetoelectric crankshaft and camshaft position sensors, they also detect vibration or mechanical pressure. Unlike stators and magnetoresistors, they are usually piezoelectric devices.

2. It is used to measure engine jitter and adjust the ignition advance angle when the engine bursts. It is usually piezoelectric ceramics. When the engine vibrates, the ceramics inside are squeezed to produce electrical signals. Because this electrical signal is very weak, the connection wires of ordinary shock sensors are wrapped with shielded wires.

3. It is used to determine the vibration of the engine, and it is used to adjust the ignition advance angle when the engine explodes. There are many kinds of x0dx0a detonation sensors, among which the earliest application is the magneto-retractable detonation sensor, which is mainly composed of magnetic cores, permanent magnets and induction coils.

4. The function of the explosion sensor is to detect the vibration of the engine when the engine speed changes. The shock sensor will express the vibration of the engine in the form of voltage. In order to avoid explosion during ignition, the electronic control module will delay the ignition to avoid engine explosion. .

5. The detonation sensor has several functions of the detonation sensor. The function of the detonation sensor is: it is used to determine the jitter of the engine, and it is used to adjust the ignition advance angle when the engine produces an explosion; it is an AC signal generator to detect the speed and position of the hinge. Explosive sensors include: magnetic core, permanent magnet, induction coil.

6. The functions of the automobile detonation sensor are as follows: 1. Explosive sensor is a kind of AC signal generator, but it is very different from most other car AC signal generators.
