Starting The Engine; Before Starting; General About Starting - Volvo TAMD74C Operator's Manual

Starting the engine

Make a habit of "visually" inspecting the engine and engine room before starting This will help you to quickly de-
tect abnormalities that have occurred or are about to occur. Make sure instruments and warning displays indi-
cate normal values after starting the engine.
We recommend installing a heater for the engine room to minimize start smoke when cold starting at tempera-
tures below +5°C (41°F).
WARNING! Never use start spray or similar start help. Risk for explosion!
Measures before start
1. Open the fuel cock
2. Open the seawater cock
3. Carry out the actions in the "Daily before the first start-
up" section in the maintenance schedule
4. Switch on the main switch
IMPORTANT! Never break the circuit with the
main switches while the engine is running. This
could damage the alternator.

General about starting

The engine speed control must be set to idle when the
engine is started. The EDC system ensures that the en-
gine receives the correct amount of fuel – even when the
engine is cold.
The EDC system allows the starter motor to turn over the
engine a few revolutions before fuel is injected. The lower
the engine coolant temperature the more the number of
revolutions. This raises the temperature in the combustion
chamber, ensuring reliable starting and reducing smoke
during starting.
The idling speed is also governed by the engine coolant
temperature (ECT) and is slightly higher when starting
from cold.
