The engine preheating assembly (4) provides a cold-start capability for the diesel engine. This assembly
A heating system with air and exhaust hoses, supplied with fuel from the fuel tank assembly through
two fuel hoses (inflow and return flow);
An electric oil pump connected with oil hoses to the diesel engine sump and to an air-oil-heat
An air-oil-heat exchanger connected with an oil hose to the diesel engine oil filler neck;
A heat exchanger box containing the air-oil-heat exchanger and electric oil pump; and an air flap, ac-
tuated by a puller magnet, mounted on the heat exchanger box;
An air hose, located above the oil hose from the sump to the electric oil pump, through which hot air is
An air hose running from the air flap to the diesel engine, through which hot air is blown onto the fuel
injection pump and diesel engine cylinder heads;
A length of pipe flanged onto the heat exchanger box, through which hot air is blown onto the gen-
The control circuit installed in the control cabinet assembly.
Qualification for desert conditions - i.e. protection of the diesel engine from sand and dust - is the result
of suitably dimensioned air, fuel, and oil filters.
1.11.3 Generator Compartment.
The generator compartment contains the synchronous generator, control cabinet assembly, fuel tank as-
sembly, battery set assembly, and air filter assembly.
The synchronous generator (13) is fastened to the base frame assembly by two shock absorbers, and
connected to the diesel engine with a clutch. It is cooled by a fan wheel located on the engine end of the
generator shaft. Cooling air is drawn in at the back of the unit hood assembly, passes over the windings
of the synchronous generator, and is exhausted through an air guide box in the base frame assembly.
The synchronous generator cables, protected by corrugated hoses, are bolted to the control cabinet. The
control cabinet (11) is fastened to the base frame assembly by four shock absorbers, and connected to
the base frame assembly by a ground strap (9). Assemblies N1 to N5, the contactors, the timing relays,
the thermistor relay F12, the circuit breakers, and the filter box (FK) are mounted to the back wall either
directly or on mounting bars. The controls and displays are located in the front panel section. After un-
locking four quick- release fasteners, the upper front panel section can be swung to the right and se-
cured. The key that unlocks the fasteners is located on the housing frame. The connection panel with the
connectors is located in the lower front panel section, which is bolted to the control cabinet. The connec-
tion panel is used to connect the control and power cables that are permanently connected to the EPP III
power distribution unit.
The fuel tank assembly (8) consists of a tank with a capacity of 101.7 gallons (385 liters), on which an
electric fuel pump is mounted. The fuel tank is connected to the tank by a fuel hose. Mounted on the in-
