Bdc: Bottom Dead Center, Referring To The Location Of The Piston At The Bottom Of The Stroke
Bimetal Engine: Engines Composed Of Cast Iron Block And Aluminum Heads
Blowby: Gasses That Escape Past Piston Rings
Companion Cylinders: Term Given To Pairs Of Cylinders Found In Engines With Even Number Of Cylinders
Compression Ratio: The Ratio At Which The Air Fuel Gas Mixture Is Compressed
Displacement: Refers To The Volume That The Piston Displaces In The Cylinder Firing
Order: The Sequence In Which The Spark Plugs Fire In Each Cylinder
Lower End: Refers To The Location At The Bottom Of The Block Where The Crankshaft And Bearings Are Located

CHAPTER O UTLINE
In A Simple One-Cylinder Engine, The Reciprocating (Up-And-Down) Motion Of The Piston Is Changed
To Usable Rotary Motion By The Connecting Rod And Crankshaft. A Flywheel Gives Momentum To The
Crankshaft Between Power Strokes. Valves Control The Engine’s Intake And Exhaust. (Ppt Slide 4)
During One Four-Stroke Cycle, The Intake, Compression, Power, And Exhaust Strokes Are
Completed. This Action Takes 720°, Or Two Crankshaft Revolutions. (Ppt Slide 5)
