How the car turbine works

2021-02-25

The turbocharger is a forced guidance system. It compresses the air flowing into the engine. The compressed air allows the engine to press more air into the cylinder, and more air means more fuel can be injected into the cylinder. Therefore, the combustion stroke of each cylinder can generate more power. Turbocharged engine produces much more power than the same ordinary engine. In this way, the power of the engine can be significantly improved. In order to obtain this performance improvement, the turbocharger uses the exhaust gas discharged from the engine to drive the turbine to rotate, and the turbine drives the air pump to rotate. The maximum speed of the turbine in the turbine is 150,000 revolutions per minute-which is equivalent to 30 times the speed of most car engines. At the same time, due to the connection with the exhaust pipe, the temperature of the turbine is usually very high. To

Turbochargers are generally installed behind the exhaust manifold of the engine. The exhaust gas discharged from the exhaust branch pipe drives the turbine to rotate, and the turbine is connected to a compressor installed between the air filter and the suction pipe through a shaft. The compressor compresses the air into the cylinder. The exhaust air from the cylinder passes through the turbine blades, causing the turbine to spin. The more exhaust gas that flows through the blades, the faster the turbine spins. At the other end of the shaft connecting the turbine, the compressor draws air into the cylinder. The compressor is a centrifugal pump that sucks air in the center of the blades and throws the air outside as it rotates. In order to adapt to speeds up to 150,000 rpm, turbochargers use hydraulic bearings. Hydraulic bearings can reduce the friction encountered when the shaft rotates. The components connected to the turbine are: exhaust branch pipe, three-way catalytic converter, intake pipe, water pipe, oil pipe, etc.
