Unit injectors

P0006026

The engine has unit injectors with two solenoids for
more precise injection. This provides better combus-
tion and minimizes particle emissions, which provides
for cleaner exhaust.

The injectors are centrally located between the four
valves and are held in place in the cylinder head by
yokes (

1

). The lower injector section is separated from

the cooling jacket by the copper sleeve (

2

) and the O-

ring (

3

). The unit injector's lower part is sealed against

the copper sleeve by a steel gasket (

4

). The ring-

shaped space for fuel metering (

5

) around each injec-

tor is sealed with two O-rings (

6

and

7

).

A unit injector can in principle be divided into three
main parts:

A Pump section

B Valve section (actuator)

C Nozzle section

The valve section contains two solenoid valves – the
spill valve (

8

) and the needle valve (

11

) with solenoids

(

9

and

10

) and return springs.

During the

filling phase

the pump piston moves up

and fuel from the cylinder head fuel channels is forced
into the unit injector.

During the

spill phase

he pump piston moves down

and fuel is forced back out into the cylinder head fuel
channels. During the period when the solenoids are
unenergized and the spill valve is open no pressure
is able to be built up in the fuel channel to the injector.

In the

pressure building phase

the spill valve sole-

noid is energized and the spill valve closes. A high
pressure then builds up in the fuel channel (

14

). The

pressure also builds up in the chamber (

15

) behind

the needle valve, which acts on the needle valve pis-
ton (

12

) and prevents the needle valve (

11

) from

opening the nozzle valve (

13

).
