(2) Cylinder pressure leakage test
If the measured value of the compression pressure test is not within the specifications, perform the
cylinder pressure leakage test.Specified value ▶
Perform this test in the sequence of firing order.
Do not test the cylinder pressure leakage with wet type test procedure. (do not inject the engine oil
into the combustion chamber) -
-
Test condition: normal engine operating
temperature (80˚C)Specified value
Whole engine below 25%
at valve and cylinder head gasket below 10%
at piston ring below 20%
Crank the engine for approx. 10 seconds by
using the start motor. 2.
Record the test result and measure the
compression pressure of other cylinders with
same manner. 3.
If the measured value is out of specified
value, perform the cylinder pressure leakage
test. 4.

Vacuum pump
Pump capacity: 210 cc/rev
Camshaft speed:
375 to 3,000 rpm
Lubrication temperature:
-40 to 155°C
Oil: 5W30
Drive type: Driven by exhaust
Camshaft sprocket
EGR cooler bypass valve
This valve is controlled by ECU. When the engine
is cooled, the exhaust gas goes to combustion
chamber without passing through EGR cooler
because the valve is closed by vacuum pressure.
2. VACUUM PUMP
Vacuum pump generates the vacuum pressure and supplies it to EGR cooler bypass solenoid. This
pump is single vane type and displacement is 210 cc/rev. The lubrication oil is supplied through the
hole in hollow shaft.

1. SYSTEM DESCRIPTION OF E-VGT
(Electric-Variable Geometry Turbine)
The E-VGT turbocharger has one shaft where at each ends are installed with two turbines having
different angles to connect one end of housing to the intake manifold and the other end to the exhaust
manifold. 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.
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.
The E-VGT system installed to the D20DTR 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
(EActuator) which controls more quickly and precisely than the previous vacuum type actuator.
