Preservation and Storage of Engine
If the engine is to be put out of service for a comparatively long period of time, it is necessary to preserve it according to the following procedure:-
After the engine stops and still does not cool yet, drain out completely the lube oil, cold water and fuel immediately. Clean the oil sump and oil strainer.
Clear out the dust and oil on the engine surface. With antirust oil smear all the unpainted exposed surfaces of engine except rubber and plastic parts.
Heat the filtered lube oil to 110 to 120°C until all bubbles in the surface of oil disappear, then pour the dehydrated oil in to the oil sump until oil level reaches the upper mark, and turn the engine in order to make sure that the lube system is completely filled up with this oil.
Pour some dehydrated oil into cylinder through injector assembled holes on the cylinder head and turn the crankshaft to make sure that the piston, piston rings, cylinder liner and valve seat are all covered with a layer of this oil.
Block the outlets of intake and exhaust manifolds (silencer) with wooden plugs or wrap up properly with plastic film in order to prevent any dust from getting in.
The engine should be stored in a clean room with good ventilation and low humidity. The engine should be covered. Chemicals near it are strictly prohibited.
The preservation according to the above procedure may be valid for 3 months. Over this Period, repeat the procedure.
In RSRTC bus 6 cylinder four stroke diesel engine is used. There are various parts of such engine.
The piston of an internal combustion engine is acted upon by the pressure of the expanding combustion gases in the combustion chamber space at the top of the cylinder. This force then acts downwards through the connecting rod and onto the crankshaft. The connecting rod is attached to the piston by a swiveling gudgeon pin (US: wrist pin). This pin is mounted within the piston: unlike the steam engine, there is no piston rod or crosshead.
The pin itself is of hardened steel and is fixed in the piston, but free to move in the connecting rod. A few designs use a 'fully floating' design that is loose in both components. All pins must be prevented from moving sideways and the ends of the pin digging into the cylinder wall, usually by circlips(lock).
Pistons are cast from aluminium alloys. For better strength and fatigue life, some racing pistons may be forged instead. Early pistons were of cast iron, but there were obvious benefits for engine balancing if a lighter alloy could be used. To produce pistons that could survive engine combustion temperatures, it was necessary to develop new alloys such as Y alloy and Hiduminium, specifically for use as pistons.
