Fuel Injector Data and Fuel Injector Video


BASIC PRINCIPLES FUEL INJECTION
The heart of the fuel injection system is the
control unit, a small electronic ""computer.""
Various sensors transmit information to the
control unit concerning air temperature, engine
temperature, engine speed, and engine load. The
control unit uses this information to determine
the exact amount of fuel to be distributed to the
cylinders.

Fuel System

Figure 5 is a simplified drawing of the fuel
system. The fuel pump draws fuel from the
front-mounted fuel tank through a filter and delivers
it to 4 injectors. A pressure regulator on the return
line maintains fuel pressure at 28 psi. Excess fuel
from the regulator returns to the fuel tank.
The control unit controls the fuel pump through
a relay, not shown in Figure 1 or Figure 4. When
the ignition switch is turned on

Electronic Fuel Injection (EFI) system

General information
From the 1990 model year, an Electronic
Fuel Injection (EFI) system controlled by the
Electronic Engine Control IV (EEC IV) system,
and incorporating an Electronic
Distributorless Ignition system (E-DIS 4) is
used on all 1.6 litre fuel injection models. The
system is designed to meet the requirements
of the European 15.04 exhaust emission
control laws.
Those components more easily related to
the ignition system are described in Chapter
5, Part B. Those relating to the fuel system are
described in this Section.
The engine management and fuel systems
are best described by dividing them into two
separate sub-systems the air inlet system,
and the fuel system.
