Operating principle and advantages of turbocharger


The power output of an engine is proportional to the amount of air and fuel that can burn in the cylinder. Higher air flow through the engine provides more energy and, thus, more power. With a turbocharged engine, the air is compressed before entering the cylinder. Since it is under great pressure, a large amount of air enters the combustion chamber, which results in greater efficiency in fuel combustion. This increases the power output of the engine, giving more force and higher speed than conventional naturally aspirated engines, and also reduces the emission of exhaust gases.


Turbocharger advantages


Strict rules on emissions of exhaust gases around the world pose a challenge for car manufacturers to design engines that meet environmental standards, and simultaneously offer a comfortable and pleasant drive. Turbochargers meet this challenge and contribute to the benefits to the end user. Compared to conventional engines of the identical power, the fuel consumption of a turbocharger engine is lower, and a portion of the energy of exhaust gases, which is usually unused, is used in these engines and contributes to improving their efficiency.


Quick reaction


In standard applications, it is quite realistic that the turbocharger doubles the engine power, which results in a faster reaction when driving. Turbochargers also influence the loss of power at high engine speeds, providing advantages to trucks, construction and other engines whose motors are equipped with turbochargers.




Turbochargers recycle the energy produced by car engines, transforming more energy created by combustion of fuel in power by creating less useless heat and friction. As a result, there is a higher fuel economy in the turbocharger engine compared to conventional turbocharger-free engines. The Power / Weight ratio, with a turbocharger engine, is much better than in conventional engines. A turbocharged engine requires less space for installation than conventional engines of the same power.



Since turbochargers force more air into the engine, internal combustion is easier, more straightforward and therefore cleaner. Today's turbocharged diesel engines produce 50% less CO2 compared to conventional engines without a turbocharger.

Performance at higher altitudes


Turbo engine performance at higher altitudes is significantly better. Lower air pressure at higher altitudes can cause loss of power in conventional engines.

In contrast, the performance of the turbine improves in the same conditions due to the increased pressure difference in the turbine and the outer atmospheric pressure, which decreases with increasing altitude.

The lower air density on the compressor suction is mainly equalized. Therefore, the turbocharger hardly suffers any loss of power at higher altitudes.
