How turbocharger contribute to environmental protection

It should start with the working principle of turbocharger, which is a turbine-driven, force extra compressed air into the engine to increases an internal combustion engine’s power output. To conclude, turbocharger could increase fuel efficiency and reduce toxic engine emissions, which is a big step to control carbon emission of vehicle.

In terms of turbocharger, there are many component parts, such as turbine wheel, turbo compressor, compressor housing, compressor housing, turbine housing, turbine shaft and turbo repair kit.

In recent years, the international community imposes stricter requirements on carbon emissions. Thus, turbocharger is constantly innovating and renewal.

Firstly, to achieve highly efficient supercharging in the consumption-relevant operating ranges of the engine at the same time as sufficient flexibility to achieve the peak load operation points in a reliable way. Hybrid con­cepts also require combustion engines that are as efficient as possible in order to achieve excellent CO2 values. Turbocharging with Variable Turbine Geometry (VTG) is an optimum supercharging system for this cycle.

Another effective option for increas­ing the efficiency is the use of ball bearings for the turbocharger. This increases the efficiencies by reducing the frictional power and improving flow geometries. Turbochargers with ball bearings, have much lower mechanical losses than those with jour­nal bearings of the same size. In addi­tion, the good rotor stability allows the tip clearance on the compressor side and on the turbine side to be optimized, allowing a further increase in the over­all efficiency.

Therefore, progress made in the field of turbocharging is paving the way for further increases in the efficiency of combustion engines. Looking forward to the new development for turbocharger that contribute more to the environmental protection.
