Introduction
Basic Description
The 6 cylinder mechanical engine has fuel ignited by
compression ignition (C.I.). The engine operates on
a four stroke cycle.
The engine is started by an electric starter motor. The
starter motor turns the engine via a pinion and teeth
on the engine flywheel, refer to (PIL 09-75).
When the engine runs the crankshaft drives the
camshaft via gears. The camshaft opens and closes
the inlet and exhaust valves and via push rods in time
with the four stroke cycle. The engine has 24 valves,
2 inlet and 2 exhaust valves for each cylinder.
The crankshaft also drives a mechanical fuel
injection pump via gears. The pump injects fuel via
injectors, or atomisers into each cylinder in time with
the four stroke cycle.
The pump injects fuel via injectors, or atomisers
into each cylinder in time with the four stroke cycle.
The pump is part of the mechanically actuated fuel
injection system, refer to (PIL 18-00).
Air is drawn into the engine, via the inlet manifold
and exhaust gases exit via the exhaust manifold. The
engine uses a turbocharger which pressurises the air
at the inlet manifold, refer to (PIL 18-36).
A mechanical lubrication oil pump is driven by
the crankshaft via gears. The pump pressurises
and circulates oil for engine lubrication and cooling
purposes.
A drive belt driven by the crankshaft, drives a
coolant circulation pump, alternator, radiator cooling
fan and other ancillaries such as an air conditioning
compressor.
