Question 4

Compression ignition

Answer 4

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

Question 5

Compression ratio

Answer 5

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
