What is a turbocharger
A turbocharger is an air compressor that compresses air to increase the intake volume, thereby increasing the power output of an engine. It uses the inertia force of exhaust gas discharged by the engine to push the turbine inside the turbine, and the turbine drives a coaxial impeller, which compresses air into the cylinder to increase the pressure and density of the air, thus burning more fuel and improving the output power of the engine.
The main components of the turbocharger include rotor, bearing device, lubrication and cooling system, sealing and heat insulation device and compressor housing. The rotor is the key component of the turbocharger, responsible for compressed air into the cylinder. In addition, turbochargers also include bearing devices, lubrication and cooling systems, sealing and heat insulation devices, and fixed parts such as compressor housing, intermediate housing and turbine housing that are necessary for normal operation.
Turbocharged technology is widely used in automobiles, such as Corolla 1.2T, lavida 1.4T and other models have adopted turbocharged engines. The advantages of turbochargers include a significant increase in power and torque without increasing the displacement, but there are also some disadvantages, such as the lag in power output, which may affect the driving experience, and the working pressure and temperature of the engine after supercharging are greatly increased, which may reduce the engine life.
The main role of turbocharger is to increase the intake of the automobile engine, so as to increase the torque and power of the engine, so that the car has more power . After the turbocharger is installed, the power of the car can be increased by 40% or more, for example, the power of a 1.5T turbocharged car is equivalent to that of a 2.0L~2.3L naturally aspirated car. In addition, turbochargers can improve fuel economy and reduce vehicle exhaust emissions.
The working principle of the turbocharger is that the exhaust gas from the engine drives the turbine inside the turbine to rotate, and then drives the coaxial impeller compressed air into the cylinder. As the engine speed increases, the exhaust gas discharge speed and the turbine speed also increase, thus compressing more air into the cylinder, increasing the pressure and density of the air, so that more fuel can be burned, and thus increasing the engine output power.
However, turbochargers operate under conditions of high temperature and high-speed rotation and may face some challenges, such as high temperature and wear. To meet these challenges, the use of high-quality oil such as Petronas Flascent synthetic oil can increase thermal efficiency and reduce wear, thus extending the service life of the turbocharger.
