What is the length of the 2020 Audi A4 in meters?
1 Answers
2020 Audi A4 has a length of approximately 4.7 meters. Turbocharger: It is an integrated unit composed of a centrifugal compressor and a turbine. The main difference from a gas engine is that this unit does not have a combustion chamber or corresponding systems. The turbine operates using the exhaust energy from a reciprocating internal combustion engine, and the compressed air provided by its centrifugal compressor serves as the charge for the reciprocating internal combustion engine. In a turbocharger, the compressor impeller and turbine are mounted on the same rotating shaft, called the rotor, which is the key component of the turbocharger. Additionally, the turbocharger includes essential components for normal operation such as bearing systems, lubrication and cooling systems, sealing and insulation devices, as well as fixed parts like the compressor housing, intermediate housing, and turbine housing. Mixed-flow Turbocharger Technology: Also known as diagonal-flow turbine, it is an intermediate form between a radial-flow turbine and an axial-flow turbine. Due to the inclined blade inlet, the airflow can smoothly adapt to changes in blade shape and transition gently to the axial direction. It also effectively prevents airflow separation at the outer diameter of the impeller exit, significantly improving the internal flow field of the impeller. Compared to a radial-flow turbine of the same diameter, the flow capacity increases by about 40%, meeting the development requirements for turbochargers to become faster and higher-capacity.
