Hyundai Venue: Engine Control System / Injector. Description and operation
Based on information from various sensors, the ECM can calculate the fuel amount
to be injected. The fuel injector is a solenoid-operated valve and the fuel
injection amount is controlled by length of injection time. The ECM controls
each injector by grounding the control circuit. When the ECM energizes the injector
by grounding the control circuit, the circuit voltage should be low (theoretically
0V) and the fuel is injected. When the ECM de-energizes the injector by opening
control circuit, the fuel injector is closed and circuit voltage should momentarily
peak.

Description
Continuous Variable Valve Timing (CVVT) system advances or retards the valve
timing of the intake and exhaust valve in accordance with the ECM control signal
which is calculated by the engine speed and load.
By controlling CVVT, the valve over-lap or under-lap occurs, which makes better
fuel economy and reduces exhaust gases (NOx, HC) and improves engine performance
through reduction of pumping loss, internal EGR effect, improvement of combustion
stability, improvement of volumetric efficiency, and increase of expansion work...

Seat belt warning light (for driver’s seat)
As a reminder to the driver, the seat belt warning light will illuminate for
approximately 6 seconds each time you place the ignition switch to the ON position
regardless of belt fastening. However, if the seat belt is unfasted, a warning chime
will sound for approximately 6 seconds.
