Bosch fuel injection pump
The boost control fitted to the Bosch fuel pump is a
diaphragm type (A1). A KSB type cold starting aid and
a stop solenoid may also be fitted to these pumps.
Lucas DP200 Series fuel injection pump
Lucas DP200 Series fuel injection pumps are fitted to
naturally aspirated engines and turbocharged
engines.
These pumps have an electrically operated cold start
device (B3) which retards the timing for normal
operation. Other features of this pump include a boost
control (B1) and a stop solenoid (B2). These pumps
are fitted with a self-vent feature.
Stanadyne fuel injection pump
Some naturally aspirated engines have a Stanadyne
fuel injection pump (C) fitted. The electrical stop
solenoid on these fuel pumps is fitted inside the
governor housing. The earth connection (C1) and the
electrical supply connection (C2) are on top of the
governor housing.
Atomisers
The atomisers, which are of the valve covered orifice
(VCO) type, have nozzles with five holes. the
atomisers inject fuel in a very fine spray into the
combustion chamber in the top of each piston. Each
atomiser is fastened to the cylinder head by a gland
nut.
The atomisers are set in the factory, but they must be
checked in accordance with the preventive
maintenance schedules. The pressure at which
atomisers operate can be adjusted by a change of
shims fitted above the spring.
For details of the atomiser setting pressures for the
engine, see the data and dimensions at the end of this
section.
