1. Read the text, translate and answer the questions. Operating troubles in general

Every engineer knows that it is impossible to predict ail the possible troubles that may arise in an engine room. Most of the possibilities for derangements of a general nature include the following.

CRACKED CYLINDERS AND CYLINDER HEADS - Cracks may result from unequal heating due to poor design, bad castings, air pockets in jackets, lack of cooling water and overloading.

Cracking from the first two causes seldom occurs. Troubles arising from air pockets are eliminated by periodical opening of the vent cocks on the cylinder heads. When for any reason the cooling water supply to part or all of cylinders fails, the engine should not be kept in operation long while the trouble is being corrected.

CRACKED CRANKSHAFTS - When a crankshaft does crack the fracture usually occurs in a crank pin or crankweb. If one bearing wears down more than the others the shaft bends, which results in breakage.

VIBRATION.- Normally Diesel engines run with very little vibration, but it sometimes happens that the engine has a critical speed, at which the twisting impulses, imparted to the crankshaft by the pressure acting on the piston, coincide with the natural period of vibration of the crankshaft. At this speed violent vibration occurs. This critical speed should be passed through as rapidly as possible when maneuvering and the engine should always operate below or above these speeds.

2. Speak about fuel oil characteristics.
