Exhaust gas valve is a component of a diesel engine which serves as the
exhaust gas discharge of combustion in the cylinder and ensure that the former of
combustion gases out of the cylinder in total. This valve is moved using a
mechanical drive. Condition of the exhaust gas valve is very influential on the
diesel generator, because the exhaust gas valve directly connected to the
combustion chamber in diesel engine generator.
Writer take a method of qualitative using analisys techniques Urgency
Seriousness Growth (USG). USG is one of the priorities in order to prepare issues
must be completed. The trick is to determine much address the crisis, seriousness
and development issue with determine a scale of 1-5 or 1-10. Issues that has a
total the highest scores priority is issues.
From the discussion and research conducted, there are some important issues
to be discussed, that is: factors that cause damage to the exhaust gas valve, the
influence of the exhaust gas valve damage to the diesel generator and an attempt
to overcome damage to the exhaust gas valve. The conclusion that can take is the
author of the exhaust gas valve damage can be caused by several factors, that is:
setting improper valve gap, lack of cooling on the valve, the use of heavy fuel and
material fatigue. Suggestions authors regarding the above issue is expected to the
machinist to improve the treatment of exhaust gas valve, with good attention to
the factors that cause damage to the exhaust gas valve and improving the care of
the systems associated with exhaust gas valve.
