7.5 DPF System (Diesel Particulate Filter)
(1) General Description
• This system reduces emissions of PM (particulate matter). In order to collect PM, a DPF cleaner with built-in catalytic
filter is mounted on the center pipe. The collected PM is handled with combustion processing during operation.
(2) System Configuration
(3) Various Sensors
Exhaust Gas Temperature Sensor
• The exhaust gas temperature sensor is installed to the front and rear of the DPF to detect the temperature in these
positions. The engine ECU controls the exhaust temperature for PM combustion based on the signals from this sen-
sor. The sensor element is a thermistor.
