As the information source of the automotive
electronic control system, automotive sensors are the key components of
automotive electronic control systems. The higher the degree of automotive
electronics and automation, the greater the dependence on sensors. Some
functional ceramic materials can adapt to the harsh environment (high
temperature, low temperature, vibration, acceleration, humidity, noise, exhaust
gas) unique to the car for a long time and be applied to the car sensor.
1. Ceramic temperature sensor. The engine
electronic fuel injection system can use ceramic temperature sensors to
continuously and accurately measure the cooling water temperature, intake air
temperature, and exhaust temperature, so as to correct or compensate the fuel
injection amount according to temperature changes, change the idle speed
control target value, etc., to obtain the best air-fuel ratio.
2. Ceramic exhaust gas sensor. The zirconia
sensor used for automobile exhaust gas monitoring is installed in the manifold
or front exhaust pipe. It uses solid electrolyte gas-sensitive ceramic
materials to measure the O2 concentration in exhaust emissions, and then feeds
the measured value back to the engine intake and fuel supply system , Detect
the air-fuel ratio of the engine, and promote the combustion of the fuel to
always maintain a full combustion state. In addition to saving fuel, it can
also reduce emissions of harmful gases such as CO and NO2. It has high
sensitivity, good reliability and long service life.
3. Ceramic knock sensor. The ceramic knock
sensor can make the engine work at the ignition time close to knocking, the
highest thermal efficiency, and the least fuel consumption, to achieve a
knock-free working state, and to ensure its operation with the maximum possible
power and economic indicators.
4. Ultrasonic sensor. Ultrasonic sensors
are usually composed of aluminum alloy shells, piezoelectric ceramic
transducers, sound-absorbing materials, and lead electrodes. They are used as
car reversing anti-collision alarm devices to guide the safe driving of cars,
especially suitable for long-loaded cars and heavy-duty trucks. , Mining trucks
and other large vehicles. Ultrasonic sensors are also used in air flow meters
to detect the size of engine air intake.
5. Ceramic acceleration sensor. Ceramic
acceleration sensors are used in automobile airbag systems, which can be used
to detect the instantaneous low-speed or high-speed collision strength of the
automobile, and convert it into electrical signal output to ensure that when
the collision strength is high, the airbag is opened accurately and in time to
improve the safety performance of the automobile. It is highly accurate and
reliable, and can quickly distinguish the actual collision situation.
6. Ceramic humidity sensor. The interior of
the automobile humidity sensor is equipped with a porous sintered body made of
metal oxide series ceramic materials. The adsorption of water molecules on the
surface of the sintered body is used to sense humidity. The characteristic
quantity of humidity sensing is resistance, and the humidity is detected by the
change in resistance value. The change. It is suitable for the detection of
anti-frost and condensation of window glass and the air humidity of the engine
intake.
