1. FUEL FLOW OF D20DT (EURO 4) ENGINE
According to input signals from various sensors, engine ECU calculates driver's demand (position of the
accelerator pedal) and then controls overall operating performance of engine and vehicle on that time. ECU
receives the signals from sensors via data line and then performs effective engine air-fuel ratio controls
based on those signals. Engine speed is measured by crankshaft speed (position) sensor and camshaft
speed (position) sensor determines injection order and ECU detects driver's pedal position (driver's
demand) through electrical signal that is generated by variable resistance changes in accelerator pedal
sensor. HFM (Hot Film Air Mass) sensor detects intake air volume and sends the signals to ECU.
Especially, the engine ECU controls the air-fuel ratio by recognizing instant air volume changes from air flow
sensor to decrease the emissions (EGR valve control). Furthermore, ECU uses signals from coolant
temperature sensor and air temperature sensor, booster pressure sensor and atmospheric pressure sensor
as compensation signal to respond to injection starting, pilot injection set values, various operations and
variables.
