Land Rover Diesel Distributor Pumps Bosch Bosch Manual

Advantages
– Flexible adaptation enables optimi-
zation of engine behavior and emission
control.
– Clear-cut delineation of individual func-
tions: The curve of full-load injected fuel
quantity is independent of governor
characteristic and hydraulic configuration.
– Processing of parameters which pre-
viously could not be performed me-
chanically (e.g., temperature-correction
of the injected fuel quantity characteris-
tic, load-independent idle control).
– High degree of accuracy throughout
complete...

Prospects
On the electronically-controlled distrib-
utor pumps of the future, the electrical
actuator mechanism with control collar
for fuel metering will be superseded by a
high-pressure solenoid valve. This will
permit an even higher degree of flexibility
in the fuel metering and in the variability
of the start of injection. 
Design and construction
This pump is of modular design. The field-
proven distributor injection pump can thus
be combined with a new electronically
controlled fuel-metering system...

High-pressure solenoid valve
The high-pressure solenoid valve must
fulfill the following assignments:
– Large valve cross-section for efficient
filling of the high-pressure chamber,
even at very high rotational speeds,
– Low weight (low moving masses), to
keep the loading of the parts to a mini-
mum,
– Short switching times to guarantee
high-precision fuel metering, and
–
Magnetic forces which are powerful
enough to cope with the high pressures.
The high-pressure solenoid valve is com-
prised of:
– The...

Since leakage and heat losses reduce the
pressure and the temperature of the A/F
mixture at the end of the compression
stroke, the cold diesel engine is more diffi-
cult to start and the mixture more difficult to
ignitethan it is when hot. These facts make 
it particularly important that start-assist
systemsare used. The minimum starting
temperature depends upon the engine
type. Pre-chamber and swirl-chamber
engines are equipped with a sheathed-
element glow plug (GSK) in the auxiliary
combustion chamber...

Flame glow plug
The flame glow plug burns fuel to heat
the intake air. Normally, the injection 
system’s supply pump delivers fuel to the
flame plug through a solenoid valve. The
flame plug’s connection fitting is pro-
vided with a filter, and a metering device
which permits passage of precisely 
the correct amount of fuel appropriate 
to the particular engine. This fuel then
evaporates in an evaporator tube sur-
rounding the tubular heating element 
and mixes with the intake air. The resulting
mixture...
