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
