ENGINE MOUNTING APPARATUS OF DIESEL ENGINE USING VARIABLE GEOMETRY TURBOCHARGER

摘要

An engine mounting apparatus for a diesel engine using a VGT is provided to improve vibration and noise performance by reducing a dynamic spring constant of an engine mounting in high speed and high load. An engine mounting apparatus for a diesel engine using a VGT comprises a VGT(Variable Geometry Turbocharger) system, an ECU, a solenoid valve and an engine mounting(10). The ECU receives transfer information of a vehicle from the VGT system. The solenoid valve receives air pressure from the VGT system according to exhausted flow rate and receives an operation signal from the ECU according to the transfer information. The engine mounting receives air pressure from the solenoid valve. The engine mounting comprises a connection support(12), a rubber section(14), an upper case(16), a lower case(46), a partition(30), an upper fluid chamber(20), a diaphragm(44), a lower fluid chamber(40), an opening and closing device(35), a hose(45) and a frame support(42).
