What is the difference between a motor and an engine?
x5
motor used to power smaller electronics, while engines used to provide more power to heavier equipment
A disk or wheel that changes the energy of moving gases or liquids into rotary motion
x4
Turbine
A plug that slides inside a cylinder in an engine
Piston
What was the problem with using steam engines as a source of power for transportation?
x4
Did not produce enough power
What happens during the power stroke in a four-cycle gasoline engine?
Pressure in the cylinder builds up very quickly and pushes the piston down
What is the purpose of the electric spark used in an internal combustion engine?
To cause combustion starting the engine
A type of engine that pushes a vehicle forward as hot air and exhaust are shot out of the back of the engine
Jet Engine
The part of an engine that changes the reciprocating motion of the pistons to rotary motion that turns the wheels
Crankshaft
Name the three forms of transportation people used until the development of engines
x3
Wind
Flowing Water
Muscle Power
Name the three different types of gas turbine engines
x3
Turbojet
Turbofan
Turboprop (Turboshaft)
Which is the most reliable internal combustion engine?
Gas Turbine
A fuel mixture that causes an explosive thrust; once started it can be started or stopped at any time
Liquid Propellant
A fuel mixture that causes an explosive thrust; once started it cannot be stopped
Solid Propellant
what is the difference between operating a steam engine and a steam turbine?
x2
Steam Engines - Pistons moving up and down
Steam Turbines - Develop power from spinning disk
What ignites the fuel inside the diesel engine?
The high air temperature ignites the fuel immediately
Why cant a jet engine operate in space?
Needs oxygen in order for thrust from the engines
