2) Belt Tensioner
(1) Overview
The torque deviation from crankshaft affects the components in belt drive system and the belt
movement. The auto tensioner system is to adjust this deviation automatically.
In D20DTR engine, one of the mechanical tensioner, pivot damped tensioner is used to keep the
damping force, system reliability and durability. The single belt drive system needs to use the automatic
belt tensioning device to transfer the power to pulleys effectively. To get this, the tensioner uses the
spring and damping unit.

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.
