•  A variable geometry turbocharger has been adopted.

•  The turbocharger consists of mainly a turbine wheel, a compressor wheel, guide blades, and a guide blade actuator.

•  When the exhaust gas flows to the turbine wheel, the turbine wheel and the compressor wheel that is on the same axis as the turbine wheel rotate to compress the intake air.

•  The opening angle of the guide blades changes according to the movement of the guide blade actuator rod.
