First, the application of ceramics in the car engine

New ceramic is zirconia and other inorganic non-metallic sintering made. Zirconia ceramic compared with the previous use of alumina ceramics, the strength is more than three times its ability to withstand more than 1000 degrees Celsius high temperature, new materials to promote the development of new uses on the car. For example: to reduce the fuel consumption of diesel engines more than 30%, it can be said that the new ceramic is an indispensable material. Now the gasoline engine, the burning energy of about 78% is lost in the heat and heat transfer, diesel engine thermal efficiency of 33%, compared with the gasoline engine is very advantageous, but still more than 60% of the thermal energy loss. Therefore, in order to reduce this part of the loss, with good insulation properties of ceramic materials around the combustion chamber for insulation, and then use exhaust turbocharger and power turbine to recover the exhaust energy, test proved that this can increase the thermal efficiency to 48%. Zirconia ceramic parts zirconia ceramic parts At the same time, due to the use of new ceramics, diesel engine instantaneous fast start will become possible. With a new type of ceramic turbocharger, it has more superior heat resistance than today's superalloys and only about one-third of the metal turbines. Therefore, the new ceramic turbine can compensate for the shortcomings of metal turbine dynamic response. Other studies are carried out: the use of new ceramic piston pin and piston rings and other moving parts. Engine efficiency is expected to improve due to weight reduction.

Second, the special sensitive ceramic in the automotive sensor applications

The requirements for automotive sensors are long-term for the harsh environment (high temperature, low temperature, vibration, acceleration, humidity, noise, exhaust) unique to the car, and should have the characteristics of small light weight, good reusability and wide output range. Ceramic heat-resistant, corrosion-resistant, wear-resistant and its potential excellent electromagnetic and optical properties, in recent years with the progress of manufacturing technology and make full use of sensitive ceramic materials made of the sensor can fully meet the above requirements.

Third, the application of ceramics in the automotive brake

 Ceramic brakes are made on the basis of carbon fiber brakes. A carbon fiber brake disc is originally made of carbon fiber and resin, it is pressed by the machine forming, and then after heating, carbonation, heating, cooling and other processes made of ceramic brakes, ceramic brakes on the surface of carbon silicon compounds hardness close to the diamond, disc The carbon fiber structure inside it is strong impact resistance, corrosion resistance, so that the disc is extremely wearable. At present, such technology in addition to the F1 car in the application, in the super civilian sports car also involved, such as Mercedes-Benz CL55 AMG.

Fourth, the application of ceramics in the car shock absorber advanced

The vibration damping device of the car is a kind of intelligent shock absorber which is successfully developed by using the positive piezoelectric effect of the sensitive ceramic, the reverse piezoelectric effect and the electrostrictive effect. Due to the use of highly sensitive ceramic components, this shock absorber has the ability to identify pavement and can do self-regulation, the car can be caused by rough road vibration to a minimum.
