“Wear†is the killer that harms the car's well-being. According to statistics, 80% of the car problems stem from the lack of internal protection of the car; causing excessive engine wear; showing the decline of power, fuel consumption, engine noise, car shake, burning oil, etc.; Affecting the normal progress of the vehicle. The nano-smooth oil increase agent developed by Professor Li Zhengxiao of Peking University, USA, provides a useful plan to reduce wear.
The nano-smooth oil increase agent is nano-assembled and dissipated; the nano-diamond is evenly dispersed into the smooth oil; constitutes a thermodynamically stable phase; significantly promotes the application performance of the smooth oil. Because the "nano-ball bearing layout film" is depicted as a special Adsorption function; change to tumbling; not only reduce the wear and tear; and it can reduce the hard conflict situation when the engine is working at high speed in the gap; then reach the intention of keeping the car safe; together; because hundreds of millions of spherical nano-diamonds The stability of the smooth oil exists; the smooth oil film becomes a composite layout; the strength is greatly enhanced; the air tightness is correspondingly improved; the useful power of the engine and the cylinder pressure are improved. The data indicates: participating in the nano smooth oil increase agent in the engine oil; After 5 minutes of work; the cylinder pressure can be promoted by 20 to 30%; the engine noise is reduced by 18 decibels.
Nano-smooth oil increase agent is the physical skill to improve the smooth oil application performance; 1 to 1000 micro-increasing share does not change the physical and chemical goals of the oil itself; nor does it have any chemical reaction inside the engine oil or engine. Good effect and safety High, easy to use. Let users spend 1 yuan to save 10 yuan. If the cooperative fuel increase agent is used together; can also experience more and more strange effects.

The vibration sensor(Vibration Transmitter) is one of the key components in the testing technology of Vibration Measurement. Its main function is to receive the mechanical quantity and convert it into a proportional electric quantity. Because it is also an electromechanical conversion device. So we sometimes call it a transducer, a vibration pickup, etc.
Commonly used vibration sensors are as follows:
1. Piezoelectric resonant
The piezoelectric sheet is used to receive the vibration signal, and the resonance frequency of the piezoelectric sheet is relatively high. In order to reduce the resonance frequency, it is realized by increasing the mass of the piezoelectric sheet vibrating body, and using a spring ball instead of an appendage to reduce the two resonance frequencies and enhance the vibration effect. Its advantages are high sensitivity and simple structure. However, the signal needs to be amplified and sent to a TTL circuit or a single-chip microcomputer circuit, but it is enough to use a triode single-stage amplification
2. mechanical vibration
In the traditional vibration detection method, after being vibrated, the spring ball vibrates at a reduced amplitude for a long time, and this vibration is easy to be detected by the detection circuit. The vibration output switch signal is determined by the output impedance and the resistance value of the matching output. According to the input impedance of the detection circuit, it can be made into a high-impedance output mode.
3. Micro Vibration Sensor
The mechanical vibration sensor is miniaturized, the vibration body is carbonized and sealed, and its working performance is more reliable. The output switching signal is directly connected with the TTL circuit and or the input circuit of the single-chip microcomputer, and the circuit structure is simple. The output impedance is high, and the quiescent working current is small.
Advantages of Vibration Sensors
1. Small size and light weight. It can be applied to some vibration test systems that are greatly affected by the additional mass.
2. It has a wider response frequency range of 4Hz-2000Hz than the magnetoelectric speed sensor, and the mechanical moving parts are not easy to damage
