1. SYSTEM DESCRIPTION OF E-VGT
(Electric-Variable Geometry Turbine)
A turbocharger is a centrifugal compressor powered by a high speed turbine that is driven by an engine's
exhaust gases. Its benefit lies with the compressor increasing the mass of air entering the engine (forced
induction), thereby resulting in greater performance (for either, or both, power and efficiency). As the
turbine, at exhaust end, is rotated by exhaust gas pressure the impeller, at intake end, gets rotated to
send air around center of the impeller, being circumferentially accelerated by the centrifugal force, into
the diffuser. The air, which has been introduced to the diffuser having a passage with big surface,
transforms its speed energy into the pressure energy while being supplied to the cylinder improving the
volume efficiency. Also, the exhaust efficiency improves as the exhaust turbine rotates. The
turbocharger is often referred to as the exhaust turbine turbocharger.
The E-VGT system installed to the D20DTF engine variably controls the passages of the turbine
housing to regulate the flow rate of the exhaust gas. The actuator of E-VGT is a DC motor actuator (E-
Actuator) which controls more quickly and precisely than the previous vacuum type actuator.
The engine ECU controls the E-Actuator electronically as follows:
Diffuser: With the meaning of spreading out it is a device that transforms fluid's speed energy into the
pressure energy by enlarging the fluid's passage to slow down the flow.
At low speed: Narrows the flow passage for the exhaust gas, resulting in increasing the flow speed
of the exhaust gas and running the turbine quickly and powerfully.
At high speed: Expands the flow passage for the exhaust gas, resulting in increasing the mass flow
of the exhaust gas and running the turbine more powerfully. -

Inspection
Measure the current while removing the fuses one by one. If the current drops sharply when a certain
fuse is removed, inspect the affected circuit. 1.
