The 1106C genset is electronically controlled. The
1106C genset 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 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. .
