Many modern large slow speed diesel engines used for main propulsion operate with a so called constant pressure turbocharging system. What is meant by constant pressure when used to describe such a turbocharging system?

Pressure variations in the scavenge air supply are avoided by supplementing the air supply with air from the auxiliary blowers so keeping a constant pressure across the load and speed range.

Pressure variations at the turbocharger inlet are damped out due to the large volume of the exhaust receiver and the short lengths of pipe from individual cylinders.

The exhaust pipes from groups of three cylinders are joined together before entry into the turbocharger so that the exhaust pulses from each cylinder cancel each other giving a constant inlet pressure.

The exhaust gas pressure is maintained constant by using a bypass waste gate to dump excess pressure at high engine loads.

Which type of cargo pump works by the cargo being drawn into the pump at high speed and being thown outwards against the pump casing by rotating impellers?

Centrifugal.

Positive displacement.

Reciprocating.

Self-priming.

Apart from temperature there are few differences between carrying cargoes of chilled meat, minus 1 degree Celsius, and frozen meat, minus 18 degrees Celsius. A key difference is that for frozen meat the cooling fans are operated at half speed or some are switched off whereas for chilled meat the fans are run constantly at full speed. Select, from the options given, the main reason for this difference in fan operation.

It is an energy saving measure since chilled meat cargoes do not require as much cold air.

The chilled meat is more sensitive to damage and therefore tighter temperature control is necessary.

The fans may be damaged if they were run at full speed delivering very cold air to the frozen cargo.

Running the fans at full speed would generate too much heat which may affect the frozen meat.

The time-weighted concentration of a substance to which a worker may be repeatedly exposed for a normal 8 hour working day and 40 hour week without adverse health effects.

The maximum concentration of harmful vapour to which a worker may be exposed for a period of 15 minutes up to 4 times within any 24 hour period without adverse respiratory effects.

Indicate the correct name for the part marked on the sketch:

Exhaust valve

Piston

Cylinder liner

Main bearing

Modern medium speed diesel engines normally have relatively short crankshafts with large diameter pins. How do these design features affect the reliability of crankshaft deflection readings?

The design of the crankshaft has very little effect on the readings when compared to the inaccuracies that arise due to human error.

Very short, stiff crankshafts do not deflect even when the engine is running so the readings are unaffected.

They increase the risk of inaccurate readings due to the 'stiff' shaft having very small natural sag which may therefore result in 'floating journals' in the static condition.

They reduce the risk of inaccurate readings as the large diameter pins result in a relatively heavy shaft which will reduce the risk of 'floating journals'.

During bilge pumping operations the pump suction gauge indicates a high vacuum. What is the most likely cause of the high vacuum reading?

Leaking pump gland.

A glogged bilge strainer.

A hole in the suction line.

Broken suction gauge.
