Description
 
The center hub rotating assembly (CHRA) houses the shaft that connects the compressor impeller and turbine. It also must contain a bearing system to suspend the shaft, allowing it to rotate at very high speed with minimal friction. For instance, in automotive appliions the CHRA typically uses a thrust bearing or ball bearing lubried by a constant supply of pressurized engine oil. The CHRA may also be considered "water-cooled" by having an entry and exit point for engine coolant. Water-cooled models use engine coolant to keep lubriing oil cooler, avoiding possible oil coking (destructive distillation of engine oil) from the extreme heat in the turbine. The development of air-foil bearings removed this risk.
Ball bearings designed to support high speeds and temperatures are sometimes used instead of fluid bearings to support the turbine shaft. This helps the turbocharger accelerate more quickly and reduces turbo lag.Some variable nozzle turbochargers use a rotary electric actuator, which uses a direct stepper motor to open and close the vanes, rather than pneumatic controllers that operate based on air pressure.
 
 
Characteristic
 
1.New government fuel economy and emissions targets.
2.Increasing oil prices and a consumer focus on fuel efficiency.
3.Only 10 percent of light vehicles sold in the United States are equipped with turbochargers, making the United States an emerging market, compared with 50 percent of vehicles in Europe that are turbocharged diesel and 27 percent that are petrol boosted.
4.Higher temperature tolerances for petrol engines, ball bearings in the turbine shaft and variable geometry have reduced driveability concerns.
