Day 6 Progress Check Flashcards
(11 cards)
What is the primary function of a reciprocating engine?
To convert pressure into rotational motion
What is the primary advantage of liquid cooling in aircraft engines?
Improved efficiency
What is the role of the crankshaft during the power stroke?
It converts linear motion to rotary motion.
How do air-cooled engines transfer heat from cylinders to the air?
Via metal fins on the cylinders
In an aircraft, where does the crankshaft transfer power to?
Propeller(s)
What is the cooling method used by most aircraft engines?
Air cooling
Where do reciprocating engines transfer excess heat to for cooling?
Surrounding air
When does the intake valve typically close during the compression stroke?
Around 50° to 75° after BDC
What are some fuels that reciprocating engines can use?
Gasoline, diesel, or alternative fuels
How does the intake stroke of a reciprocating engine function?
Air-fuel mixture is drawn into the cylinder.
In a two-stroke-cycle engine, does the intake and the exhaust process take place within the same stroke?
yes
