What kind of crankshaft should you use for a v-type engine with 12-cylinder assembly?
A engine develops power output for each two engine revolution. * Your answer It is the difference in expansion amounts between the cylinder head and pushrod that effectively increases the space between the valve stem and the rocker's arm. * Your answer On a four-stroke cycle reciprocating engine, which strokes are both valves close? * Intake Power Ignition Compression Exhaust It represents the net power output of the engine at the crankshaft. * Your answer If the fuel/air ratio is proper and ignition timing is correct, the combustion process should be completed just after center at the beginning of the power stroke. * Your answer
In a four-cylinder engine with a firing order of 1-3-4-2, what stroke is piston #4 on when #1 is on its compression stroke?
Discuss the comparison of 4-stroke and 2-storke cycle engine (provide drawing if necessary)
Which does makes the volumetric efficiency of the reciprocating engine decrease? * Low cylinder head temperatures Improper valve timing Full throttle operation Sharp bends in the induction system High carburetor air temperatures When the piston reaches the bottom center it reverses direction and starts moving up on the compression stroke. TRUE OR FALSE? * Your answer What happens with the volumetric efficiency when the engine's heat increases? Your answer As an aircraft climbs, air density decreases, thereby decreasing the amount of air in the fuel/air mixture. This results in a vibrant air/fuel mixture which causes a reduction in engine power. TRUE OR FALSE? * Your answer

AND ANSWER IN WHOLE NUMBERS ONLY) * Your answer On a four-stroke cycle reciprocating engine, which strokes are both valves open? * Power Compression Intake Exhaust Ignition The primary concern in the firing order of the opposed engine is to keep the power impulses on adjacent cylinders as close as possible to obtain the most outstanding mechanical efficiency. TRUE OR FALSE? * Your answer A nine-cylinder engine with a bore of 5.5 inches and a stroke of 6 inches will have a total piston displacement of? (TYPE NUMBERS ONLY, AND THE UNIT IS CU. INCH AND ANSWER IN WHOLE NUMBERS ONLY) * Your answer
