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

It represents the net power output of the engine at the crankshaft. * Your answer If the fuelair ratio is proper and ignition timing is correct, the combustion process should be completed just after center at the beginning of the power stroke. * our answer The ignition time varies from 20 to 35 degrees before the top dead center to ensure complete combustion when the piston is slightly past the top quiet center position. TRUE OR FALSE? * Your answer
