Chapter 1 - Vocabulary Flashcards
Actuators
X
Charge air coolers
X
Compression
X
Compression ignition
The process by which compression raises the air temperature above the fuel’s ignition temperature causing combustion to occur instantly as the fuel is injected, eliminating the need for a mechanical ignition system which are necessary in gasoline engines
Compression ratio
A comparison of the volume of air in a cylinder before compression with its volume after compression
ex. 16:1 compression ratio means that at the top of the compression stroke, the air in the cylinder takes up 1/16 the volume it did when the piston was at the bottom of the compression stroke

Diesel engine
X
Diesel fuel
Fuel used in diesel engines that contains more heat (BTUs or joules) than gasoline does
Electric ignition
X
Electronically controlled fuel injection systems
X
Emission controls
X
Exhaust
X
Four-stroke cycle
X
Governor
A device that senses engine speed and load and changds fuel delivery accordingly
Intake

Stroke
The up or down movement of the piston within the cylinder
Four stroke - One stroke each for intake, compression, power, and exhaust
Two stroke - all four actions are accomplished with only two piston strokes, one up (intake and compression) and one down (power and exhaust).
