Control Unit

ECU receives and processes signals from data sensors and switches to control fuel delivery. Frequency and duration of injection (fuel delivery time) is controlled by ECU. Fuel delivery time is modified for operating conditions such as cold starting, altitude, acceleration and deceleration.

NOTE: Components are grouped into 2 categories. First category covers INPUT DEVICES, which control or produce voltage signals monitored by ECU. Second category covers OUTPUT SIGNALS, which are components controlled by ECU.
