Precision engine bearing inserts are manufactured with a small portion of the bearing ends extending beyond the bearing housing or caps. The installation process of these bearings requires sufficient
The method of piston cooling in which oil is delivered through the connecting rod to a compartment within the piston, then distributed by the motion of the pistons, and allowed to drain to the crankcase via one or more holes or pipes, is termed
The piston rod scraper box incorporated in a two-stroke/cycle, crosshead diesel engine serves to
In a large, slow-speed, main propulsion diesel engine, which of the parts listed is under tension when the engine is running?
The main advantage of unit injectors (combined fuel pump and injector) over other fuel injection systems is
Passages are drilled in the crankshafts of diesel engines to provide lubricating oil to the
When may the crankcase ventilation pipes or oil drain pipes of two or more engines be connected?
The main function of tie rods in the construction of large, low speed diesel engines is to
On most modern diesel engines, the main and connecting rod bearings receive their lubricating oil by
Fuel injection pumps using the port and helix metering principle requires the use of a
Lubricating oil is supplied to the crankpin bearings in a marine diesel engine by
gudgeonpin bearings are difficult to lubricate because of their oscillating motion and
The camshaft drive is designed to maintain proper camshaft speed relative to crankshaft speed. In maintaining this relationship, the camshaft drive causes the camshaft to rotate at
Engines having a bore exceeding 250 mm, but not exceeding 300 mm are to have at least
The opening of an exhaust valve on a modern, large, low- speed, main propulsion diesel engine, may be actuated by
Shaker, circulation, and spray are the three general methods used in
The speed of the camshaft in a two-stroke/cycle diesel engine, running at 950 RPM, is
Explosion relief valves on diesel engine crankcases should relieve the pressure at not more than
A two stroke diesel engine exhaust temperaturewill be lower than a four stroke diesel engine of the same displacement because the ___________. I. scavenging air is cooling the exhaust gases II. exhaust cycle time is longer
The sealing surfaces of a diesel engine piston ring are considered to be the faces in contact with the cylinder wall, in addition to the ring groove ___________.
