DESCRIPTION AND OPERATION OF CAMSHAFT AND ROCKER SHAFT/ENGINE BRAKE ASSEMBLY
AND RELATED PARTS
2.1.1
Engine Braking
The engine uses an integral engine brake. Engine braking is controlled electronically by the
engine control system with an electric solenoid. When activated, the solenoid allows oil pressure
to activate a piston on the exhaust rocker arm. Engine braking is accomplished with a single
exhaust valve in each cylinder. The exhaust camshaft uses a separate engine brake-only lobe that
allows for double valve activation for high ef
fi
ciency braking. The exhaust valve is
fi
rst operated
toward the completion of the intake stroke, closed during the compression stroke and opened a
second time when the compression stroke is completed. The engine brake system is enabled using
the following components:
For EPA07 engines:
□
Engine brake solenoid valve in front of engine applies low engine braking.
□
Engine brake solenoid valve in rear of engine applies medium engine braking.
□
For high, both front and rear solenoids are activated.
□
Six exhaust rocker arms with actuator pistons.
□
Six brake rocker arms which are actuated by the brake cam lobes.
□
Exhaust camshaft has one brake cam lobe per cylinder.
