What is the principle of turbocharging?

The earliest turbochargers were used in sports cars or formula racing cars, which made the engine gain more power in those racing competitions with limited engine displacement.

As we all know, the engine generates electricity by burning the fuel in the cylinder. Because the fuel input is limited by the amount of air sucked into the cylinder, the power generated by the engine is also limited. If the running performance of the engine is in the best state, increasing the output power can only increase the fuel quantity by compressing more air into the cylinder, thus improving the combustion function. Therefore, under the current technical conditions, the turbocharger is the only mechanical device that can increase the output power of the engine without changing the working efficiency.

The turbocharging device we usually talk about is actually an air compressor, which increases the air intake of the engine by compressing air. Generally speaking, turbocharging is to use the inertia impulse of the exhaust gas discharged by the engine to drive the turbine in the turbine room, and the turbine drives the coaxial impeller to pressurize the air sent by the air cleaner pipeline into the cylinder. When the engine speed increases, the exhaust gas discharge speed increases synchronously with the turbine speed, and the impeller compresses more air into the cylinder. With the increase of air pressure and density, more fuel can be burned. The output power of the engine can be increased by increasing the fuel quantity and adjusting the engine speed accordingly.

You may think that the turbocharger is complicated, but it is not. Turbocharging device is mainly composed of turbine chamber and supercharger. First, the air inlet of the turbine chamber is connected with the exhaust manifold of the engine, and the air outlet is connected with the exhaust pipe. Then the air inlet of the supercharger is connected with the air cleaner pipeline, and the air outlet is connected with the air inlet manifold. Finally, the turbine and the impeller are respectively installed in the turbine chamber and the supercharger, and are coaxially and rigidly connected. Such an integrated turbocharging device is completed, and your engine is "overclocked" like a computer CPU.

Supplement: Theoretically speaking, turbocharging technology can be installed in all cars, but there are differences in each model. For example, the crankshaft, crankshaft bearing and connecting rod bearing of the engine equipped with turbocharger are reinforced, and the air flow sensor, pressure sensor and computer data adjustment are different from ordinary cars. Therefore, it is not easy to install a turbocharger on an ordinary car unless you have relevant professional technology and equipment.
