Turbocharged working principle

Turbo is referred to as TURBO. If you see TURBO or T at the rear of the car, it means that the engine used in the car is a turbocharged engine. For example, Volkswagen's 1.8T, Passat's 1.8T, Audi's 2.0T and so on. The engine work of these cars relies on the fuel to burn in the engine cylinders to output power. In the case of a certain engine displacement, if you want to increase the output of the engine, the most effective way is to provide more fuel combustion. However, it is easy to provide more fuel into the cylinder, but it is difficult to provide a sufficient amount of air to support complete combustion of the fuel, which is difficult to achieve by conventional engine intake systems.

In terms of the working principle of the gasoline engine, each kilogram of gasoline is supplied to the cylinder, and about 15 kilograms of air is required to the cylinder to ensure full combustion of the gasoline. However, the volume of this 15 kg of air will be very large, and it is not easy to completely inhale such a large volume of air by the vacuum generated by the cylinder during the engine intake. Therefore, it is particularly important to increase the ability of the engine to draw in gas, that is, to increase the efficiency of the engine. Supercharging technology is a way to improve the intake capacity of the engine. In principle, it uses a special compressor to pre-compress the gas before entering the cylinder, increasing the density of gas entering the cylinder and reducing the volume of the gas. Thus, the mass of the gas is greatly increased per unit volume. The amount of intake air can meet the combustion needs of the fuel, thereby achieving the purpose of improving the engine power. The compressor used in the pressurization process is also called a supercharger.
