Vacuum Lines Schematic Layout :
Description :
The above schematic shows the vacuum circuit. A
vacuum pump provides vacuum to the vacuum
solenoid valve and the brake booster.
The vacuum generated by the vacuum pump is
stored in the vacuum reservoir.
The vacuum circuit of Brake booster and vacuum
solenoid valve are separated by a Non return
valve.
The NRV and vacuum reservoir is provided so
that there is no vacuum starvation by EGR cooler
bypass valve irrespective of braking applications.
The vacuum reservoir is mounted to fire wall with
the help of a bracket.
