Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of turbochargers, in particular to a turbocharger with a variable cross-section. Background Art
[0002] The variable geometry turbocharger (VGT) is an advanced supercharging technology. Its background technology primarily addresses the limitations of traditional turbochargers. A turbocharger combines a centrifugal compressor and turbine into a single unit. Unlike a gas turbine, this unit lacks a combustion chamber and associated systems. Instead, the turbine utilizes the exhaust energy of a reciprocating internal combustion engine, and the compressed air provided by the centrifugal compressor acts as the engine's charge. In traditional turbochargers, turbine size, turbine airflow, and turbine hysteresis are three mutually exclusive considerations. While conventional turbochargers offer a substantial airflow at full load, they are unable to reach the operating speed at low engine speeds due to insufficient exhaust gas driving force. This results in poor low-speed performance, even inferior to that of a naturally aspirated engine of the same displacement.
[0003] While variable-geometry turbochargers improve engine efficiency, they also face the challenge of high-temperature operating environments. Effective heat dissipation is key to ensuring the long-term stable operation of variable-geometry turbochargers, and worn parts need to be replaced in a timely manner to avoid heat dissipation problems caused by component failure. Most existing variable-geometry turbochargers are complicated to disassemble and inconvenient to replace parts; therefore, we propose a variable-geometry turbocharger to solve this problem.
