DEFINITION
• Engine: machine for converting energy into motion or mechanical work
• Fuel (oil, petrol, steam …) Engine mechanical energy (rotary motion of shaft)
• Engine vs. Motor

CLASSIFICATIONS
– form of energy they utilize, as steam, compressed air, diesel and gasoline
– the type of motion of their principal parts, as reciprocating and rotary
– the place where the exchange from chemical to heat energy takes place, as internal combustion and external combustion
– the position of the cylinders of the engine, as V, in-line, flat, and radial
– the number of strokes of the piston for a complete cycle, as two-stroke and

INTERNAL COMBUSTION ENGINES
• Continuous combustion: gas turbine, jet engine, etc.
• Intermittent combustion: 2 stroke, 4 stroke, Wankel rotary engine, etc.

4 STROKE PETROL ENGINE
• STROKE: The distance the piston moves when traveling from Bottom dead center (BDC) to Top dead center (TDC) or vice versa.

4 TROKE PETROL ENGINE – Cooling system
keep the engine from overheating by transferring this heat to the air
allow the engine to heat up as quickly as possible, and then to keep the engine at a constant temperature.
