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 _____________./crankshaft speed in a two-stroke cycle diesel engine Camshafts are usually driven by timing gears or ___________./chain drives Additional explosion relief valves are fitted on separate spaces of the crankcase such as gear or chain cases for camshaft or similar drives when the __________./gross volume of such spaces exceeds 21 cubic feet Additional explosion relief valves are fitted on separate spaces of the crankcase, such as gear or chain cases for camshaft or similar drives, when the _______./gross volume of such space exceeds 0.6 cubic meter The valve cam slope angle determines the _____________./acceleration rate of valve opening and closing The shape of a diesel engine cam determines the ___________./all of the above The valve cam slope angle determines the _____________./opening and closing rate of the valve The arrangement and shape of the cams on a diesel engine camshaft directly control which of the listed groups of operating conditions?/Firing order, valve timing, and valve lift When two cams of the same diameter, one with tangential flanks and the other with convex flanks are compared, the cam with tangential flanks will cause___________./more abrupt valve action When a hydraulic valve lifter is on the base circle of the cam, "zero" valve lash is maintained by the ______________./plunger spring In a diesel engine, with the valves set to specification, the shape of the cam determines the valve _____________./all of the above The shape of a cam on a diesel engine determines the valve's __________./All of the above are correct. On a large diesel engine installation, crankshaft axial alignment is maintained by the ______________./engine thrust bearing The main reason counterweights are added to crankshafts is to _____________./provide uniform loading and wear of main bearings A crankshaft whose center of gravity coincides with its center line is said to be __________./statically balanced The amount of fuel injected in a particular time, or degree, of crankshaft rotation is termed _____________./rate of injection The governor controlling a diesel engine modulates crankshaft RPM by adjusting the _____________./fuel injection pumps The most important factor in engine performance is the actual power output at the end of the crankshaft available for doing work. This is known as _____________./brake horsepower A diesel engine which is rated for normal operation at a crankshaft speed of 800 RPM, is commonly classed as a ____________./medium-speed diesel A crankshaft whose center of gravity coincides with its center line is said to be __________.
