PURGE SWITCHOVER VALVE
1 Purge Switchover Valve
2 Line to Engine
3 Line to Canister
4 Canister
Functions The fuel vaporization control system is installed to inhibit the fuel vaporized gas from discharging into the atmosphere. Thefuel vaporized gas that is accumulated in the canister abstractsthrough the purge switchover valve purification during the engine combustion (except the decreasing mode) and coolant temperature of over 80 °C. For this reason, the ECU transacts
the engine speed, air inflow quantity, coolant temperature, andintake temperature. The purge switchover valve is activated by the ECU frequency according with the engine rotating speed to adjust the purification rate. The purification rate is determined by the continuous valve opening interval. The purge switchover valve is activated by the ECU for the following conditions :
Coolant temperature of over 80 °C
Engine speed of over 1000rpm
2 Minutes after starting
When the fuel cut-off mode is not activated

HUBER EGR
SYSTEM DESCRIPTION The following chart shows the relationship between the input and the output in Huber EGR control unit. Compared to traditional system that only operates theEGR valve with RPM sensor and Micro switch, the HuberEGR control unit bring big differences that of traditionalsystem on the functions.
Input Signal
RPM sensor (CPS)
EGR valve lift sensor
Throttle position sensor (TPS) - M/T
Shift lever position
Throttle position sensor (TPS)
Vehicle speed sensor(VSS) Basic input signal for EGR operation Engine cold or hot signal
Position signal of EGR valve that is triggered by vacuum modulator 1 Transfer the engine load signal to the control unit directly (manual transmission)
TCU (A/T)
EGR
Control
Unit
Coolant temperature sensor (CTS)
Solenoid valve (Control forvacuum modulator 2)
If the control unit determines it is in no-load sharp accel- eration mode after analyzing the input signals, this conver- sion type switch reduces the fuel consumption by cutting off the intake air pressure from
fuel injection ALDA and gen- erating the vacuum pressure. In no-load sharp acceleration
mode, Duty Control ( continu- ous precise control) is acti- vated according to the varia- tions of the input signals when the solenoid valve generates the vacuum pressure in ALDA.
Vacuum modulator 2
The opening value of the modulator is precisely con- trolled by input signals and programmed MAP, and the opening value of EGR valve is also changed by the varia- tions of vacuum pressure to EGR valve. The changed opening value is transferred to the control unit as input signal.
Vacuum modulator 1
TCU in automatic transmission equipped vehicle transfers the information such as driving conditions and speeds into the EGR control unit. EGR control unit uses the shift lever position and vehicle speed as important information for operating the solenoid valve during no-load sharp acceleration mode. In manual transmission, the signal of vehicle speed is transferred into the EGR control unit directly.
Clutch switch
In manual transmission, the clutch switch is the one of core elements to determine driving condition. Output Signal
