Automotive Knowledge Base Turbocharged Engine

The turbocharger is actually an air compressor that increases the amount of intake air by compressing the air. It uses the inertial impulse of the exhaust gas emitted by the engine to propel the turbine in the turbine chamber. The turbine also drives the coaxial impeller. The impeller pressures the air sent from the air filter duct to pressurize it into the cylinder. When the engine speed increases, the exhaust gas discharge speed and the turbine speed also increase at the same time, the impeller will compress more air into the cylinder, the air pressure and density increase can burn more fuel, increase the fuel amount and adjust the engine's Speed, you can increase the engine's output power.
The turbocharger is the only mechanical device that enables the engine to increase its output power without changing its operating efficiency. The earliest turbochargers were used on sports cars or formula cars so that the engines could get more power in racing cars where the engine's displacement was limited. The turbocharged English name is Turbo. Generally speaking, if we see Turbo or T at the rear of the car, it means that the car's engine is a turbocharged engine.
The earliest turbochargers were used on sports cars or formula cars so that the engine could get more power in racing cars where the engine's displacement was limited.
The engine is powered by the combustion of fuel in the cylinder to generate power. Because the amount of fuel input is limited by the amount of air drawn into the cylinder, the power generated by the engine is also limited, if the engine's operating performance is at its best. Increasing the output power can only increase the amount of fuel by compressing more air into the cylinder, thereby improving the combustion performance. 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 operating efficiency.
Turbocharging device is actually an air compressor, which increases the intake air volume of the engine by compressing air. In general, turbocharging uses the inertial impulse of exhaust gas emitted by the engine to propel the turbine in the turbine chamber. The turbine also drives the same. The impeller of the shaft, which pushes the air sent from the air filter duct to pressurize it into the cylinder. When the engine speed increases, the exhaust gas discharge speed and the turbine speed also increase at the same time, the impeller will compress more air into the cylinder, the air pressure and density increase can burn more fuel, increase the fuel amount and adjust the engine's Speed, you can increase the engine's output power.
The main role of turbocharger is to increase the intake of the engine, thereby increasing the power and torque of the engine and making the car more powerful. When an engine is fitted with a turbocharger, its maximum power can be increased by 40% or more compared to when no turbocharger is installed. This means that the same engine can produce more power after being pressurized. Take our most common 1.8T turbocharged engine, after pressurization, the power can reach the level of 2.4L engine, but the fuel consumption is not much higher than the 1.8 engine, on another level is to increase Fuel economy and reduced tailpipe emissions.
However, after pressurization, the pressure and temperature of the engine during operation are greatly increased, so the engine life will be shorter than the engine without the same displacement, and the mechanical performance and lubrication performance will be affected. To a certain extent, it limits the application of turbocharging technology to the engine.
