Engines
856.35 g/kWh was determined to be the CO
during the EU type approval process. This value was
recorded in EU type approval certificate. This CO
measurement results from testing over a fixed test
cycle, under laboratory conditions, with a parent
engine representative of the engine family. This value
shall not imply or express any guarantee of the
performance of a particular engine.
Engaging the Driven
Equipment
1. Operate the engine at one-half of the rated rpm,
when possible.
2. Engage the driven equipment without a load on the
equipment, when possible.
Interrupted starts put excessive stress on the drive
train. Interrupted starts also waste fuel. To get the
driven equipment in motion, engage the clutch
smoothly with no load on the equipment. This
method should produce a start that is smooth and
easy. The engine rpm should not increase and the
clutch should not slip.
3. Ensure that the ranges of the gauges are normal
when the engine is operating at one-half of the
rated rpm. Ensure that all gauges operate
properly.
4. Increase the engine rpm to the rated rpm. Always
increase the engine rpm to the rated rpm before
the load is applied.
5. Apply the load. Begin operating the engine at low
load. Check the gauges and equipment for proper
operation. After normal oil pressure is reached and
the temperature gauge begins to move, the engine
may be operated at full load. Check the gauges
and equipment frequently when the engine is
operated under load.
Extended operation at low idle or at reduced load
may cause increased oil consumption and carbon
buildup in the cylinders. This carbon buildup
results in a loss of power and/or poor
performance.
Fuel Conservation Practices

The efficiency of the engine can affect the fuel
2
economy. Perkins design and technology in
manufacturing provides maximum fuel efficiency in
all applications. Follow the recommended procedures
to attain optimum performance for the life of the
engine.
• Avoid spilling fuel.
i01646335
Fuel expands when it is warmed up. The fuel may
overflow from the fuel tank. Inspect fuel lines for
leaks. Repair the fuel lines, as needed.
• Be aware of the properties of different fuels. Use
only the recommended fuels. Refer to the
Operations and Maintenance Manual, "Fuel
Recommendations" for further information.
• Avoid unnecessary idling.
Shut off the engine rather than allowing the engine to
idle for long periods of time.
• Observe the service indicator frequently. Keep the
air cleaner elements clean.
• Ensure that the turbocharger is operating
correctly. For more information refer to this
Operation and Maintenance Manual,
"Turbocharger - Inspect"
• Maintain a good electrical system.
One faulty battery cell will overwork the alternator.
This fault will consume excess power and excess
fuel.
• The belt should be in good condition. Refer to the
Systems Operation, Testing and Adjusting, "V-Belt
Test" for further information.
• Ensure that all the connections of the hoses are
tight. The connections should not leak.
• Ensure that the driven equipment is in good
working order.
• Cold engines consume excess fuel. Utilize heat
from the jacket water system and the exhaust
system, when possible. Keep cooling system
components clean and keep cooling system
components in good repair. Never operate the
engine without water temperature regulators. All
these items will help maintain operating
temperatures.
