1106 Perkins diesel engine with electronically controlled
The 6 cylinder 1106D diesel engine uses an Electronic Control Module (ECM) that receives signals from the fuel injection pump and other sensors in order to control the fuel injectors. The pump supplies fuel to the fuel injectors. The six cylinders are arranged in-line. The cylinder head assembly has two inlet valves and two exhaust valves for each cylinder.
The ports for the exhaust valves are on the right side of the cylinder
head. The ports for the inlet valves are on the left side of the
cylinder head. Each cylinder valve has a single valve spring. Each
cylinder of 6 cylinder diesel has a piston cooling jet that is installed
in the cylinder block. The piston cooling jet sprays engine oil onto the
inner surface of the piston in order to cool the piston.

The pistons have a Quiescent combustion chamber in the top of the piston
in order to achieve clean exhaust emissions. The piston pin is
off-center in order to reduce the noise level. The pistons have two
compression rings and an oil control ring. The groove for the top ring
has a hard metal insert in order to reduce wear of the groove. The skirt
has a coating of graphite in order to reduce wear when the engine is
new.
The correct piston height is important in order to ensure that the
piston does not contact the cylinder head. The correct piston height
also ensures the efficient combustion of fuel which is necessary in
order to conform to requirements for emissions. A piston and a
connecting rod are matched to each cylinder. The piston height is
controlled by the distance between the center of the big end bearing and
the center of the small end bearing of the connecting rod.
Three different lengths of connecting rods are available in order to
attain the correct piston height. The three different lengths of
connecting rods are made by machining the blank small end bearing of
each rod at three fixed distances vertically above the centerline of the
big end bearing. . The crankshaft has seven main bearing journals. End
play is controlled by thrust washers which are located on both sides of
the number six main bearing. The timing case is made of aluminum.
The timing gears are stamped with timing marks in order to ensure the
correct assembly of the gears. When the number 1 piston is at the top
center position on the compression stroke, the marked teeth on the idler
gear will match with the marks that are on the fuel injection pump, the
camshaft, and the gear on the crankshaft. There is no timing mark on the
rear face of the timing case. The crankshaft gear turns the idler gear
which then turns the following gears: the camshaft gear, the fuel
injection pump.
The camshaft and the fuel injection pump run at half the rpm of the
crankshaft. The cylinder bores are machined into the cylinder block. The
fuel injection pump (1) that is installed on the left side of the
Perkins 1106D engine is gear-driven from the timing case. The fuel
transfer pump (33) is attached to the fuel injection pump (1). The fuel
transfer pump draws low pressure fuel from the primary fuel filter. The
fuel transfer pump delivers the fuel to the secondary filter at a
pressure of 400 kPa (58 psi) to 500 kPa (72.5200 psi).
The fuel injection pump draws fuel from the secondary filter. The fuel
injection pump increases the fuel to a maximum pressure of 130 MPa
(18855 psi). The fuel injection pump delivers the fuel to the fuel
manifold. The fuel injection pump is not serviceable. Adjustments to the
pump timing should only be made by personnel that have had the correct
training. The fuel injection pump uses the engine ECM to control the
engine RPM.
