1. OVERVIEW

The pre-heating system for D20DTF engine has the glow plug to the cylinder head (combustion

chamber), and improves the cold start performance and reduces the emission level.

The pre-heating resistor (air heater) is used to heat the intake air.

This enables the diesel fuel to be ignited in low temperature condition.

The ECU receives the information such as, engine rpm, coolant temperature, engine torque, etc.,

through CAN communication during pre-heating process; and the pre-heating control unit controls the

pre-heating, heating during cranking and post-heating by the PWM control.
