In domestic small displacement engine trend more obvious today, turbo is becoming

a major maker to adopt technology, even if the Japanese companies adhere to the

naturally aspirated, is also a comprehensive layout smaller turbocharged engine. So,

we often say the turbo is how to make small displacement engines close to or even

greater than that of large displacement engine performance.

In 2020 countries for domestic passenger cars under the background of the average

fuel consumption of 5.0 L / 100 km, energy-saving technology development and cost

is a big difficulty for automakers. The current trend is that the main loading models

turbochargers emphasis on low emission, high power advantage The external

environment,the strict emissions and fuel consumption standard is the important factor

to promote the development of turbo.

It is worth mentioning that the future development trend of turbocharger is electronic

supercharging technology. Electronic supercharging is to use the motor to replace the

exhaust to drive the turbine to rotate, which can eliminate the prevailing turbine

hysteresis phenomenon of turbocharging, because the control of the motor is more

accurate. Electronic supercharger is not popular at present, because the work of electronic

supercharger needs voltage support, but now the 12V voltage on the car is not enough to

meet the needs of electronic supercharger.

As the market size has grown in recent years, the penetration rate of turbochargers for

passenger vehicles in China has increased from 22 percent in 2013 to 32 percent in 2016,

reaching 7.65 million units, according to Gaishi Automotive Research Institute Gasi

Automotive Research Institute predicts that under the background of the national requirement

of the average fuel consumption of domestic passenger cars in 2020 of 5.0L/100km, turbo

permeability will reach 48% in 2020.
