Advantages and Disadvantages of Turbocharger

A turbocharged engine is an engine with a turbocharger. Its working principle is to use the inertial momentum of the exhaust gas discharged from the engine to drive the turbine in the turbine chamber, and the turbine in the turbine chamber drives the coaxial impeller, and the coaxial impeller presses the air from the air filter tube into the cylinder for pressure.

When the engine speed increases, the exhaust gas discharge speed, and the turbine speed also increase simultaneously, and the impeller compresses more air into the cylinder. The increase in air pressure and density burns more fuel, and by correspondingly increasing the amount of fuel and adjusting the engine speed, the output power of the engine can be increased.

Advantages of a turbocharger

The advantages of a turbocharger are mainly reflected in the fact that the turbocharger improves the performance and efficiency of the engine. First of all, turbochargers can significantly increase power and torque without increasing engine displacement, giving mechanical equipment excellent acceleration performance and stronger climbing ability. Secondly, the turbocharger helps improve combustion efficiency by increasing the compression ratio of the air and providing more oxygen, thereby making the fuel burn more fully, improving fuel utilization, and reducing carbon oxide and particulate matter emissions.

In addition, the advantages of the turbocharger include that the structure of the turbocharger is relatively simple, easier to install, and can be applied to engines from low speed to high speed, two-stroke to four-stroke, and small bore to large bore. Finally, turbocharged engines are usually more energy-efficient than naturally aspirated engines and comply with modern environmental protection requirements.

Disadvantages of a turbocharger

Disadvantages of turbochargers include response lag, which is due to the inertia effect between the turbine and impeller, causing the engine to have a certain delay in throttle response, which affects the operator's driving experience. In addition, the turbocharger system is more complex than a naturally aspirated engine and requires additional components, which increases maintenance costs and increases the potential risk of failure.

Moreover,  a turbocharger gives you more power, which means more energy output per second. This means you have to put in more energy and burn more fuel. This makes a turbocharger no more fuel-efficient than a non-turbo engine.

Disadvantages of a turbocharger include the fact that a turbocharger increases the pressure and temperature inside the engine, which can shorten the engine's service life. High temperature and high-pressure environments can cause damage to engine components and lubrication systems. Finally, the turbocharger requires a cooling system to control the temperature, otherwise overheating can damage the engine. Therefore, although the turbocharger provides an increase in engine performance, it also comes with these potential problems that need to be dealt with carefully.

Advantages of turbocharged engines

The biggest advantage of turbocharging is that it can greatly increase the power and torque of the engine without increasing the engine displacement. Turbocharged engines not only save more fuel but also reduce carbon monoxide, hydrocarbons, and particulate matter in emissions.

The turbocharged engine has a simple structure, convenient installation, and wide technical adaptability, and can be applied from low speed to high speed, from two-stroke to four-stroke, and from small bore to large bore.

In addition, turbocharged engines are less noisy than naturally aspirated engines.

Disadvantages of turbocharged engines

Granted, turbocharging does increase the power of an engine, but it also has a number of drawbacks, the most obvious of which is the laggy response of the power output. Due to the inertia of the impeller, the reaction to sudden changes in the throttle is slower, which means that there is a time difference between the time when the accelerator is stepped on to increase power and the time when the impeller rotates to send more air pressure into the engine to obtain more power. Generally speaking, a modified turbo takes at least 2 seconds to increase or decrease the power output of the engine.

With the advancement of technology, although various turbocharger manufacturers are improving turbocharger technology for air intake & exhaust system, due to the design principle, the driving experience of a car equipped with a turbocharger is different from that of a large-displacement car.

After supercharging, the pressure and temperature of the engine during operation are greatly increased, so the engine life will be shorter than that of the same displacement engine without supercharging, and the mechanical performance and lubrication performance will be affected, which is also to a certain extent. Limits the application of turbocharging technology in the engine. Therefore, timely cooling of the cylinder is a major problem that needs to be broken through at present.
