Scavenge

port

inspection

provides

useful

information

about

the

condition

of

cylinders,

pistons,

and rings, at low expense. The inspection consists of visually examining the piston, the rings and

the lower part of the cylinder liner, directly through the scavenge air ports To reduce the risk of

scavenge box fire, remove any oil sludge and carbon deposits in the scavenge air box and receiver

in connection with the inspection.

The port inspection should be carried out at the first stop after a long voyage, e.g. by anchoring if

possible, to obtain the most reliable result with regard to the effectiveness and sufficiency of the

cylinder lubrication and the combustion cycle (complete or incomplete)

A misleading result

may be obtained if the port

inspection is carried out after arrival at harbor,

since

manoeuvring

to

the

quay

and

low-load

running,

e.g.

river

or

canal

passage,

requires

increased

cylinder

oil

dosage,

i.e.

the

cylinders

are

excessively

lubricated,

Further,

during

low

load, the combustion ccle might not be as effective and complete as expected, due to the actual

fuel

oil

qualities

and

service

(running)

condition

of

the

fuel

injection

equipment.

It

is

highly

recommended to take this information into consideration.

89. The components of an engine involved in normal scavenge port inspection comprise _______.

①

the piston

②

piston rings

③

the lower part of the cylinder liner

④

the fuel injector

90. If the scavenge box had too much oil sludge and carbon deposits, what would occur?

A. excessive cylinder oil consumption

B. the scavenge box fire

C. the crankcase explosion

D. excessive wear of the cylinder liner

91. In order to obtain the most reliable result with regard to the effectiveness and sufficiency of

the cylinder lubrication and the combustion cycle, when should the scavenge port inspection be

carried out?

A. at the first stop after a long voyage, e.g. by anchoring if possible

B. at the first stop after arrival at harbor

C. at the first stop after low load running

D. at the first stop after passing river or canal passage

Current regulations with respect to the discharge of oily water set limits of concentration 15 parts

per million. A monitor is required to measure these values and provide both continuous records

and an alarm where the permitted level is exceeded.

The principle used is that of ultra-violet fluorescence. This is the emission of light by a molecule

that has absorbed light. During the short interval between absorption and emission, energy is lost

and

light

of

a

longer

wavelength

is

emitted.

Oil

fluoresces

more

readily

than

water

and

this

provides the means for its detection.

A

sample

is

drawn

off

from

the

overboard

discharge

and

passes

through

a

sample

cell.

An

ultra-violet light is directed at the sample and the fluorescence is monitored by a photoelectric cell

Where an excessive level of contamination is detected an alarm is sounded and diverting valves

are operated. The discharging liquid is then passed to a slop tank.

93. The passage is mainly about ________.

A. oily water separator

B. current regulations related to oil pollution

C. oil in water monitor

D. the principle of ultra-violet fluorescence

94. A monitor can obtain all of the following functions except _______.

A. measuring oil content values

B. providing continuous records

C. lowering the oil content below 15 ppm

D. providing an alarm unit warning of levels of discharge in excess of 15 ppm
