Fuel System (TLDI)
5. Air Injector
The air injector injects fuel and compressed air into the
combustion chamber of each cylinder. The component
is controlled by ECU to inject the amount of fuel mixture
at the timing that is best suited to the current engine
operation conditions based on the information from
sensors.
6. Fuel Injector
The fuel injector supplies the gasoline contained in the air
rail to the air injector through the fuel injector insert. The
component is controlled by ECU to supply the amount
of fuel that is best suited to the current engine operation
conditions based on the information from sensors.
7. MAP (Manifold Pressure) Sensor (optional)
MAP sensor is located on the upper area of air chamber,
and measures the air chamber inner pressure (vacuum
pressure) and sends the signal to ECU.
ECU uses this signal to establish fuel injection amount
and ignition timing.
8. M AT ( M a n i f o l d Te m p e r a t u r e ) S e n s o r
(optional)
MAT sensor is located on the upper area of air chamber,
and measures intake air temperature and sends the signal
to ECU.
