Task 1. Find the answers to these questions in the text which follows:
a) What are the five actions performed by the fuel injection system?
b) What jobs must the engineer responsible for the main engine do to maintain the fuel injection system in good working order?
c) What is ships fuelling station equipped with?
d) Where is the fill pipe connected to?
e) What is an overflow arrangement needed for?
f) Why is one of the tanks called the day fuel tank?
g) What are the functions of the transfer, pump, booster pump, centrifuge and filter?
The equipment used on board a diesel-driven ship for handling and controlling fuel oil belongs to separate systems.
Fuel injection system performs the following functions: (1) it meters the quantity of the fuel required by the engine and maintains this quantity constant; (2) it injects fuel at the correct point in the cycle at all engine speeds and loads; (3) it begins and ends injection very quickly; (4) it injects fuel at the rate necessary to control combustion; (5) it atomizes fuel in the chamber of each cylinder. The most important devices of this system are high-pressure fuel pumps and fuel injection valves.
The engineer who has the main engine in his charge is responsible for the efficient operation, maintenance, adjustment and repair of the fuel injection system.
Fuel fill and transfer system has the necessary tanks, piping, valves and pumps to receive fuel oil aboard, store it and into the day tank. On either side of the main deck there is a ship’s fuelling station equipped with one or more fill pipes. Special overflow arrangements are provided for this purpose.....

Frictional wear ______ the materials used in the liner and in the piston rings. It ______ between the sliding surfaces of the cylinder liner and the piston rings. It ______ between the sliding surfaces of the cylinder liner and the piston rings. It ______ by inefficient lubrication of the cylinder or by overloading the engine. In addition, engine operating conditions also ______ frictional wear. For example, frictional wear ______ if the air and f
