Turbocharger that in the eyes of many people think is to bring strong power to the vehicle components, from the birth to the general public, to today, it is not only a symbol of strong power, but also bear the responsibility of the car energy saving and environmental protection.

Turbo: The end of large displacement?

In the days before turbochargers were widely used in the automotive sector, large displacement engines were common in both commercial vehicles and passenger cars to meet the demand for vehicle power. The reason is simple, one of the most direct means to improve engine power, that is, inject more fuel and air, and the way to increase the fuel and air is to increase the number of cylinders or increase the cylinder volume.

For example, the first domestic 8-ton diesel truck ---- Huanghe 150, whose naturally aspirated engine displacement is close to 12 liters; then, for example, the Japanese Isuzu GALA bus, with a body of 12 meters, but equipped with a 19-liter naturally aspirated V10 diesel engine. Although the large displacement engine can ensure the smoothness of power and acceleration, but also eat a lot of.

With the maturity of turbocharged technology, its application in the automotive field has also broken the inherent concept of "displacement determines power". Today, turbocharged diesel engines with a displacement of 6 to 13 liters can meet the power needs of conventional commercial vehicles. In the passenger car segment, such examples are everywhere.

Vehicles with turbocharged engines are far more powerful than naturally aspirated engines of the same displacement, because of the intervention of the turbocharger, the engine intake does not only rely on its own negative vacuum pressure to suck in air, but also with the help of turbocharging, the air is pressed into the combustion chamber, improving the volumetric efficiency, so that more air The turbocharger not only relies on its own negative vacuum pressure to suck in air, but also has the help of turbocharging, which presses air into the combustion chamber and improves the volumetric efficiency, so that more air is mixed with fuel to produce higher power output at the same speed.

In addition, due to the application of turbochargers, turbocharged engines can be designed to be smaller than naturally aspirated engines when providing the same power performance.

Turbocharger: I speak for energy saving and environmental protection

The advantage of turbocharging is not only to enhance the power, today it plays a greater role with other engine advanced technology.

In recent years, words such as energy saving, environmental protection and lightweight have long been the development trend of the automotive industry. How to further improve the fuel economy of vehicles and minimize the pollution of the environment has become the focus of domestic and foreign car people. How to improve engine efficiency and achieve energy saving and environmental protection?

In terms of energy saving and emission reduction, the application of turbocharging increases the intake density of the engine and improves the movement speed of airflow in the cylinder, which is conducive to the mixing of fuel and air to achieve more complete combustion, thus reducing exhaust emissions.

It is estimated that CO2 emissions from gasoline engines using turbochargers can be reduced by about 10-20% compared to naturally aspirated engines of the same power level. The application of turbocharging ensures the fuel economy and lower emissions of a smaller engine without the loss of driving pleasure as a price.

Nowadays, in advocating the development of energy saving and environmental protection, turbocharger is not simply a magic weapon to enhance power, but has become the main weapon in the current struggle with environmental pollution in the automotive industry.
