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. The work of turbocharging is closely related to the engine. Therefore, to understand turbocharging, we must first start with the working principle of the engine.
Turbocharger Work Theory
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. The work of turbocharging is closely related to the engine. Therefore, to understand turbocharging, we must first start with the working principle of the engine.
How the engine works
The engine is powered by the combustion of fuel in the cylinder to generate power. The amount of fuel input is limited by the amount of air sucked into the cylinder. The power generated will also be limited. If the engine’s operating performance is already at its best, increase it. The output power can only increase the amount of fuel by compressing more air into the cylinder, improving the combustion function. 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.
Turbocharger mechanism of action
In fact, the turbocharger can be considered as an air compressor, which increases the intake air volume 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 by the air filter duct and pressurizes 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.
Disadvantages of turbocharger
“Hysteresis response” means that the response of the throttle due to the inertia of the impeller is slow to react. Even if the modified response time is 1.7 seconds, the engine delay will increase or decrease the output power. This will be a little off the hook for a car that suddenly accelerates or overtakes. But with the improvement of technology, this shortcoming is being gradually overcome.
In general, if we see Turbo or T in the rear of the car, it means that the engine used in the car is a turbocharged engine. I believe we all have seen many such models on the road, such as the Audi A6 1.8T, Passat 1.8T, Bora 1.8T and so on. Turbocharged vehicles require more attention when it comes to maintenance, especially for the engine. Pay special attention to the maintenance of oil and air filters.
